Bluetooth General Usage

2012 model year, and up (This information is subject to change)

  1. GM vehicles, equipped with a Bluetooth system, can use a Bluetooth-capable cell phone with a “Hands Free Profile” to make and receive phone calls.
  2. Not all phones support all functions, and not all phones are guaranteed to work with the in-vehicle Bluetooth system. For phone-specific instructions and compatibility information visit: http://www.gmtotalconnect.ca/
  3. The Bluetooth system uses voice recognition to interpret voice commands to dial phone numbers and name tags.
  4. When using the in-vehicle Bluetooth system, sound comes through the vehicle’s front audio system speakers and overrides the audio system.
  5. Use the audio system volume knob, during a call, to change the volume level. The adjusted volume level remains in memory for later calls.
  6. The system can be used while the key is in ON/RUN or ACC/ACCESSORY position.
  7. The range of the Bluetooth system can be up to 10 meters.
  8. In a Cadillac equipped w/NAV, you must say “Hands Free” before saying “Bluetooth” to access the Bluetooth menu.

The process for accessing the Voice Recognition menu will depend upon the GM model and whether it’s equipped with an onboard navigation system. You have successfully entered the Voice Recognition menu when the system responds with “Ready”. The Bluetooth control buttons (phone answer and phone disconnect) are located on the steering wheel on most GM models. Calls can be ended by pressing the (phone disconnect) button (on most GM models).

Pair Your Phone

  1. Press and hold (phone answer) for two seconds. You should hear “Ready” followed by a tone.
  2. Say “Bluetooth.” You should hear “Bluetooth ready” followed by a tone. (Most model year 2014 vehicles can skip this step and you can just say “pair phone” as your first command).
  3. Say “Pair.” You should hear “Please start a search on your Bluetooth phone” and a four-six digit PIN number. Depending on the phone, you may have to press “scan for new devices”, and/or “make this device visible to other Bluetooth capable devices” before it will be discovered. The PIN number will be used in the next step.
  4. Start the Pairing process on the cell phone that will be paired to the vehicle. Locate the device named “General Motors”. Select that device for pairing and enter the PIN number that was provided in the previous step. (Some smart phones may perform this step for you, and you will only need to press “Pair”) Reference the cell phone manufacturer’s user guide for further information on this process. For phone-specific instructions and compatibility information go to: http://www.gmtotalconnect.ca
  5. The system may prompt for a name for the phone. Use a name that best describes the phone so you will recognize it in the future, i.e. “Mike’s phone”. The system then confirms the name provided.
  6. You should hear confirmation feedback, i.e., “Mike’s phone has been successfully paired” after the pairing process is complete.
  7. Repeat Steps 1 through 7 for up to five phones to be paired. (Up to ten devices may be paired on later model 2014 vehicles).

Listing & Deleting Paired & Connected Phones

  1. Press and hold (phone answer) for two seconds. You should hear “Ready” followed by a tone.
  2. Say “Bluetooth.” You should hear “Bluetooth ready” followed by a tone.
  3. Say “List.” You should hear all of the paired phones. Only one phone can be connected at a time and the system will inform you of the connected phone with the feedback, i.e., “Mike’s phone is connected.” *Newer models may also have this option inside the telephone “App” on your infotainment system.
  4. Phones may also be deleted by saying “delete” and repeating the name tag, or by pressing the “-“ symbol inside the App (on model year 2014 vehicles and up).

Connecting to a Different Paired Phone

  1. Press and hold (phone answer) for two seconds. You should hear “Ready” followed by a tone.
  2. Say “Bluetooth.” You should hear “Bluetooth ready” followed by a tone.

Fast Facts & How To

OnStar 2G Decommission

OnStar will enable the broadest deployment of 4G LTE in the automotive industry beginning with 2015 Chevrolet, Buick, GMC and Cadillac vehicles. OnStar is committed to delivering more value and convenience for our customers through the inventive use of technology. This new, purposeful solution will make it easier for our consumers who want to connect. OnStar is constantly focused on improving our service and with 4G LTE, we will enable the most powerful OnStar connection ever.

As we integrate 4G LTE services in many of our 2015MY vehicles, OnStar has recently been informed that Canadian wireless service providers plan to decommission their 2G CDMA network services starting this year, with more significant actions commencing in mid-2015. OnStar currently depends on active and functioning 2G CDMA networks to deliver services. As a result, in order to continue to provide OnStar services without interruption, Canadian vehicles that do not have 4G LTE will need a hardware upgrade.

OnStar is working with its suppliers and service providers on the necessary hardware upgrade solutions. No action is required by our customers at this time. We will communicate additional details about the hardware upgrade solutions for all of our Canadian customers and dealers by January 2015.

  6. Get the Remote Link app here:



  7. 6 - Open the OnStar RemoteLink app on your smartphone. Enter your username and password (you will be prompted to create a new password, this will be different from your 4 digit PIN# that was set up during your OnStar welcome call. Both passwords will be valid, and your PIN# will be used inside of the app to perform functions such as remote lock and unlock). If you forget your PIN#, press the blue OnStar button in your vehicle, or call: 1-888-4-ONSTAR (888-466-7827)

OnStar RemoteLink Key Fob Services Information

The OnStar RemoteLink App is available for any (2012 model year and up) OnStar equipped vehicle.

If the app is activated during the 6 month free trial period, on any new MY 2014 and up vehicle (*with factory installed remote start and remote power-lock/unlock), after June 1st/14, the app, monthly email diagnostics, and dealer maintenance notifications will function for a 5 year period from the date of activation, even if the OnStar subscription is not renewed by the customer. (*However, if the subscription is not renewed, the real-time diagnostics and in-app NAV functions will be unavailable, as they require an active OnStar account*)

If the app is activated during the 3 month free trial period, on any used vehicle (2012 model year and up, with a factory installed remote starter) the app will function only as long as the OnStar account is kept activated by the customer. If the OnStar account is not renewed by the customer, all in app functions will cease to function.

“Factory installed remote start” refers to a remote starter being installed during the original factory build of the vehicle; any aftermarket or dealer installed remote starter is unable to be activated directly by OnStar, or the OnStar Remote Link App.

An active OnStar Directions & Connections or Safe & Sound service plan is required to access most RemoteLink features.

OnStar RemoteLink Key Fob Services do not include any emergency services, Automatic Crash Response, stolen vehicle assistance, live Advisor service, or Hands-Free Calling. If you sell your GM vehicle or wish to cancel use of OnStar Key Fob Services, you must contact OnStar at 1.888.4.ONSTAR. Subsequent owners will be able to activate the remaining term of Key Fob Services by calling 1.888.4.ONSTAR.

When OnStar RemoteLink Key Fob Services are active, location information is collected each time you use the app.

The goal for time it takes to remote start your vehicle is 30 sec.-1.5 minutes; however, it can take up to 5 minutes for the signal to remote start or lock/unlock your vehicle and respond to your phone confirming that the command has gone through, often due to weak cell signal strength, and network difficulties connecting your system to the network.

IPhone’s do seem to have a few more instances of error messages than the other brands of smartphones… ie) “error #220, your keys are within 40 feet of your vehicle”

It is also recommended that you connect to OnStar (press your blue button) once a month, and request that the advisor “check your location”, this should download and install any OnStar updates that have been released since the last time you connected to the OnStar network!

If you use the Application without an OnStar Plan, but began using the RemoteLink Key Fob Services during the free trial period, or any consecutive OnStar Plan with no lapse in coverage, you should have access to the RemoteLink Key Fob Services for a period of up to 5 years beginning on the date of the original retail sale or lease of your new OnStar equipped Model Year 2014 vehicle, or the remainder of such period if you purchase or lease a used OnStar equipped 2014 Model Year (and up) vehicle, or until the RemoteLink Key Fob Services are cancelled. To determine the amount of time remaining on the 5 year contract, please contact OnStar at 1.888.4ONSTAR.

If there is a lapse in coverage, then you may only use the RemoteLink Key Fob Services when you have a paid OnStar Plan, and will not be able to use the services after such plan expires, even if it is within 5 years of the date of the original retail sale, or lease of your vehicle. After Jan./2015, a new 4G capable mirror is needed to use OnStar services within Canada.

If the vehicle has sat for more than 4 consecutive days without a manual key-turn start, the RemoteLink remote start feature may not remote start your vehicle. This is due to the battery charge having been reduced over the 4 day span, and the onboard computer must ensure enough battery charge is present to allow the vehicle to turn over during the next key turn start. If this occurs, your remote start is functioning correctly within its programming parameters, even though no remote start has occurred.

To disconnect, cancel and fully deactivate your OnStar Plan or RemoteLink Key Fob Services, contact OnStar at 1.888.4ONSTAR.

Uninstalling the Application DOES NOT cancel these services.

***Please note: OnStar data/services may not be available in all locations, please refer to the OnStar services coverage map (be aware there are separate tabs at the top of the map indicating regular OnStar services v.s. OnStar data services (telephone, Remotelink app, turn by turn navigation directions, etc…)

Saving Navigation Destinations to Favorites

GMC Model Year 2014 and Up, Equipped With The 8” Intellilink Touch Screen
  1. Open your “NAV” icon on your Intellilink screen
  2. Click “Destination”
  3. Click either “Address”, or “Points of Interest”
  4. Type in your destination, or select one from the “Points of Interest” options
  5. This will take you to a screen that displays the options “Go” and “Save”
  6. Tap on the “Favorites” arrow on the bottom right corner of your Intellilink screen
  7. Find a blank “Favorites” block, or one that you can overwrite
  8. Press and Hold the “Favorites” block of your choice
  9. Press the “Exit” button on the top right of your Intellilink screen
  10. Tap on the “Favorites” arrow on the bottom right corner of your Intellilink screen
  11. You should now see the destination that you saved as a choice in your “Favorites” bar

Program Lat/Long Coordinates

To program a NAV destination such as coordinates from longitude and latitude, you must save the text file as a “CSV file” format, then insert it into the (USB or SD) data card slot (depending on the type of media you used to save and transfer the file), and then download the info into your NAV system.

There are two kinds of points of interest data supported by the system:

  1. User POIs — user-defined points of interest (POIs) that can later be set as a destination and found using route guidance.
  2. POI-Warnings — user-supplied areas such as hazard spots that the system displays in a pop-up window when the vehicle is approaching the designated area.

Creating User-Defined Points of Interest (POIs)

A CSV file can be created with any spreadsheet program, such as Microsoft Excel, Open Office Calc, or Google Spreadsheets.

  1. In the first column, enter the longitude value of the position of the POI.
  2. In the second column, enter the latitude value of the position of the POI.
  3. In the third column, enter the name of the POI.
49.697302 -112.786050 Davis GMC Buick
49.705321 -113.653353 Head Smashed In Buffalo Jump
49.084471 -111.616637 Writing-on-Stone Provincial Park
50.760026 -111.481762 Dinosaur Provincial Park
49.645382 -110.095231 Cypress Hills Interprovincial Park
  1. Save the file with the extension ".csv". For example: myplacesfile.csv. The name of the .CSV file will be used to create a My Points of Interest category in the system. Create separate .CSV files with different names to create other My Points of Interest categories.
  2. Make sure to select the USB mass storage device as the location to save, using the exact folder name /myPOIs for the User POIs or /myPOIs/myPOIwarnings. For POI-warnings.

Adding POIs to The System

Navigate to the "Points Of Interest" section of your Navigation. If a USB mass storage device with the new POI data is connected, the system will automatically ask if you want to transfer the POI data. Press Download to begin the transfer or Cancel to cancel the procedure.

New POI data will overwrite POI data already in the internal memory.

A maximum of 8 MB of POI data can be added to the system.

For POI-warnings, leave the storage device connected to the vehicle’s port.

Update Navigation Map Discs

Because location information on a vehicle’s navigation system ages at a rate of 10-20% per year, you may want to update the data in your navigation system to be sure it has the latest information including streets, exits, and points of interest.

The GM Navigation Disc Center has the latest information on map versions and compatibility. Map updates can be purchased two ways:

  1. Call the GM Navigation Disc Center at 1-877-628-3472
  2. Visit gmnavdisc.com

Customer Pay

GM offered a Navigation Disc Update Program for 2006 and 2007 model year vehicles. Customers who purchased vehicles with navigation systems were eligible for two free map updates.

This program concluded on December 31, 2009. The DVD Navigation Update Program policy has expired. Communications were sent to 2006 MY and 2007 MY vehicle owners when the program ended, informing them that they are no longer eligible for free annual updates.

Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is a non-flammable fluid comprised of 33% ammonia based urea and 67% purified water. DEF is used with diesel engine exhaust systems to reduce the amount of emissions produced by turning Nitrogen Oxide (NOx) into nitrogen and water vapor. DEF technology has a proven track record since it has been used in Europe for years.

Selective Catalytic Reduction (SCR)

The SCR system is an after-treatment system, since it treats the vehicle’s exhaust after combustion.

  1. A fine mist of DEF is injected into the exhaust while the engine is running.
  2. The heat from the exhaust converts the DEF into ammonia.
  3. When the ammonia, mixed with exhaust gases, reaches the SCR catalyst, the NOx emissions are broken down.
  4. The Diesel Particulate Filter (DPF) then captures soot to incinerate it during regeneration cycles.
  5. Water vapor, nitrogen and reduced emissions exit the exhaust system.

The SCR system uses DEF at a rate of about 1 to 1.25% of the vehicle’s diesel fuel usage. A full tank of DEF provides a driving range of about 8,000 kilometers. Since DEF usage is directly related to fuel consumption, range will vary depending on driving conditions.

Purchasing DEF

DEF is available at GM dealerships and most major truck stop chains. GM DEF is available in a variety of package sizes to service both individual consumers and fleets, including 3.78 litre (1-U.S. gal.) and 9.46 litre (2.5-U.S. gal.) jugs. GM will also be announcing a 208 Litre (55-U.S. gal.) drum and 1249 Litre (330-U.S. gal.) tote product offering in the later part of 2010 For your convenience, listed below are the GM part numbers for the 1- and 2.5-U.S. gallon sizes.

  1. 3.78 litre (1-U.S. gal.) part number is 88862660
  2. 9.46 litre (2.5-U.S. gal.) part number is 88863524

If purchasing DEF outside of a dealership, you must use API-certified or ISO 22241 labeled DEF.

Refilling Your DEF Tank

DEF is stored in a 20 litre tank located under the passenger side of the cab. The DEF tank fill point is conveniently located under the hood, along with other fluids that require periodic maintenance. It‘s easily identified with a blue cap.

Do not over-fill the DEF tank.

Storing DEF

DEF shelf life is typically at least one year, depending on the storage temperature. It is best stored out of direct sunlight between -5ºC and 20ºC. Small DEF spills can be cleaned up by absorbing it with dry earth, sand, or other non-combustible material and scooping it into a container for disposal. While DEF is not listed as a hazardous waste by the U.S. federal government, please use proper disposal methods. Do not empty into drains; dispose of this material and its container in accordance with all applicable local and national regulations.

Electronic Onboard Warning System

An electronic onboard warning system provides you with numerous warnings in the Driver Information Centre (DIC) to help you maintain adequate DEF levels, alert you if the DEF quality is poor or if there are concerns with the system.

Maintaining DEF Fluid Levels

The electronic onboard warning system will provide a message alerting the driver when the DEF level is around 1,600 km remaining range.

Additional messages that must be acknowledged alert the driver at the 500km, LOW, and 0km fluid ranges as the DEF tank gradually empties. The fluid level in the DEF tank must be maintained for the vehicle to run correctly. If the DEF tank is allowed to run empty, the system will alert the driver. If fluid is not added at the next vehicle start, the vehicle speed will be limited to 90 km/h and ultimately to 6 km/h in accordance with federal and provincial requirements.

Adding DEF to an Empty or Low Tank

Always add at least 1 U.S. gallon (3.78 litres) to release the vehicle from any speed limitation. Once the system is refilled, the system resets itself and a service visit is not required. It may take up to 30 seconds in park or several kilometres of driving to update the DEF level warning.

Maintaining DEF Quality

The quality of DEF in the tank must be maintained for the vehicle to run correctly. Care should be taken to prevent any contaminants from getting into the fluid. Only GM-approved DEF, or DEF fluid containing the API certified or ISO 22241 label, should be used.

Warranty Conerns

Care should be taken to avoid introducing any contaminants into the DEF tank or fluid. The SCR system is covered under the emissions limited warranty just like any other emissions component. However, system damage caused by using incorrect fluid is not eligible for warranty reimbursement. See dealer for details.

Tampering with the Exhaust System

No modifications should be made to the exhaust system in the area between the engine and the Diesel Particulate Filter (DPF). Modifications to the exhaust routing after the DPF are allowed within guidelines published on www.gmupfitter.com

Universal Remote System - 3 Light

Universal Home Remote System Three Light System

Universal Remote System Programing - One Light Model

TThis system provides a way to replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices.

Do not use this system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1st, 1982. Read the instructions completely before attempting to program the transmitter. Because of the steps involved, it may be helpful to have another person assist with programming the transmitter. Be sure to keep the original remote control transmitter for use in other vehicles, as well as, for future programming. Only the original remote control transmitter is needed for Fixed Code programming. The programmed buttons should be erased when the vehicle is sold or the lease ends. See “Erasing Universal Home Remote Buttons” later in this section. Park the vehicle outside of the garage when programming a garage door. Be sure that people and objects are clear of the garage door or gate that is being programmed.

Most garage door openers sold after 1996 are Rolling Code units. Programming a garage door opener involves time-sensitive actions, so read the entire procedure before starting. Otherwise, the device will time out and the procedure will have to be repeated

For questions or help programming the universal remote system, call 1-800-355-3515 or see www.homelink.com

Programming the Universal Remote System

***(Programming involves time-sensitive actions, and may time out causing the procedure to be repeated. If the programming hasn’t worked after completing step 3, proceed to steps 4-6)***
  1. 1 - Hold the end of the hand-held transmitter about 3 to 8 cm (1-3 inches) away from the universal remote system buttons, with the indicator light in view. (The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver.)
  2. 2 - At the same time, press and hold both the hand-held transmitter button and one of the three universal remote system buttons to be used to operate the garage door. Do not release either button until the indicator light goes from a slow to a rapid flashing light. Then release both buttons. (Some garage door openers may require substitution of step 2 with the procedure under “Radio Signals for Canada and Some Gate Operators” later in this section.)
  3. 3 - Press and hold the newly programmed universal remote system button for five seconds while watching the indicator light and garage door activation.

If the indicator light stays on continuously or the garage door moves when the button is pressed, then programming is complete. There is no need to complete Steps 4-6.

If the indicator light Does Not turn on, or the garage door does not move, a second button press may be required. For a second time, press and hold the newly programmed button for five seconds. If the light stays on or the garage door moves, programming is complete.

If the indicator light blinks rapidly for two seconds, then changes to a solid light and the garage door does not move, continue with programming Steps 4-6.

  1. 4 - After completing Steps 1-3, locate the “Learn” or “Smart” button inside the garage, on the garage door opener receiver itself. (The name and color of the button may vary by manufacturer.)
  2. 5 - Press and release the “Learn” or “Smart” button. Step 6 must be completed within 30 seconds of pressing this button.
  3. 6 - Inside the vehicle, press and hold the newly programmed universal remote system button for two seconds and then release it. If the garage door does not move or the lamp on the garage door opener receiver does not flash, press and hold the same button a second time for two seconds, then release it. Again, if the door does not move or the garage door lamp does not flash, press and hold the same button a third time for two seconds, then release it.

The universal remote system should now activate the garage door. Repeat the process for programming the remaining two buttons.

Radio Signals for Canada and Some Gate Operators

Canadian radio-frequency laws and some U.S. gate operators require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for the universal remote system to pick up the signal during programming.

*If the programming did not work, replace step #2 under “Programming the universal remote system” with the following:

Press and hold the universal remote system button while pressing and releasing the hand-held transmitter button every 2 seconds until the signal has been successfully accepted by the universal remote system. The universal remote system indicator light will flash slowly at first and then rapidly. Proceed with step #3 under “Programming the universal remote system” to complete.

Driver Assistance Systems

Some driver assistance features alert the driver of obstacles by beeping or, if equipped with the Safety Alert Seat, the driver’s seat cushion may provide a vibrating pulse alert.

The Forward Collision Alert (FCA) System

Provides a red flashing alert on the windshield, and beeps or pulses the Safety Alert Seat when approaching a vehicle directly ahead too quickly. FCA is a warning system only and does not apply the brakes.

TIP/FYI

FCA may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service.

Collision Alert

Flashes six red lights on the windshield when the vehicle approaches another vehicle too rapidly. In addition, either eight beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times.

Tailgating Alert

Will display the “Vehicle Ahead” indicator in amber when following a vehicle ahead too closely.

The Lane Departure Warning (LDW)

System is designed to help avoid crashes due to unintentional lane departures. LDW uses a camera sensor on the windshield ahead of the rear-view mirror to detect the lane markings.

Rear Vision Camera

Displays an image of the area behind the vehicle in the center stack display when the vehicle is shifted into Reverse. The camera and Rear Park Assist will not work properly if the tailgate is down.

Ultrasonic Park Assist

Operate at speeds of less than 5 mph (8 km/h) and detect objects 10 in. (25 cm) high off the ground and below bumper level, using the sensors on the bumpers. URPA detects objects up to 8 ft (2.5 m) behind the vehicle, and Front Park Assist detects objects up to 1.2 m (4 ft) in front of the vehicle. These detection distances may be less during warmer or humid weather.

Active Fuel Management

Cylinder deactivation, also known as Active Fuel Management, is now standard on all three engines. The system uses oil pressure, controlled by the Powertrain Control Module, to deactivate the lifters on selected cylinders, closing the valves for those cylinders. It deactivates four of the cylinders on the V8 engines and two cylinders on the V6 under light load conditions — operating the engines as a V4 — and seamlessly reactivates the cylinders when the driver demands greater power. The transition takes less than 20 milliseconds and is imperceptible.

Cargo & Lighting Systems





Side Blind Zone Alert

The side blind zone alert system uses two side object sensor modules to notify the driver that an object is present in one of the driver’s side blind zones. An icon on the left or right side view mirror is illuminated when an object is detected. The side object sensor modules are located on each side of the vehicle behind the rear fascia.

The Side Blind Zone Alert system may become active with no objects within range of sensors. If false side blind zone alerts occur, inspect the rear bumper fascia for signs of damage.

TIP: If the vehicle is towing a trailer or has an object such as a bicycle rack attached to the rear of the vehicle, the Side Blind Zone Alert system may not function properly and the indicators may illuminate intermittently or remain illuminated all the time.

Extending Remote Start Time

You can use your remote to extend the run time of the remote start event. Reprogramming the computer for a longer run time is not an option at this time. The Remote Vehicle Start(RVS) function allows engine starting while not in the vehicle. It also allows the vehicle HVAC system and other vehicle systems to enable, providing a comfortable vehicle upon entry.

RVS functions have an operating range of up to 195 feet, depending on conditions. The RVS sequence begins by pressing and releasing the lock button and then pressing and holding the RVS buttons on the keyless entry transmitter. The turn signal lamps will illuminate to indicate the vehicle has received the remote start request. Each time an RVS is performed, the vehicle doors are locked, however they may then be unlocked/locked with the transmitter or vehicle key at any time. Once activated, the engine is allowed to run for 10 minutes.

The RVS time may be extended by an additional 10 minutes by again pressing and releasing the lock button and then pressing and holding the RVS buttons on the transmitter. This feature is called a "RVS continue" and allows a maximum of 20 minutes of engine running. If the RVS continue is performed at 7 minutes into the initial 10 minute time-out, a total of 17 minutes of engine running would occur.

The RVS event may be suspended at any time by pressing only the RVS button on the transmitter or by entering the vehicle and turning ON the hazard lamps.

In between ignition cycles, only 2 RVS events may occur or be attempted. Once 2 events or attempts have been made, future RVS events will be suspended until the vehicle is started using the ignition.

GM Paid Oil Changes

Davis GMC Buick Lethbridge is pleased to announce a new 2-Year Scheduled Lube-Oil-Filter (LOF) Maintenance Program that will be included with the purchase or lease of all new 2014 or 2015 model year Buick and GMC vehicles.

The 2-Year Scheduled Lube-Oil-Filter Maintenance Program will provide all owners 4 L.O.F. services at no additional charge, for two years or 40,000 km (whichever occurs first). Customers are limited to four (4) LOF events during this service period.

Heated and Ventilated Seat Operation during a Remote Start

On some 2014’s, the heated or ventilated seats must be enabled through the personalization menu or they will not turn on during a Remote Vehicle Start event.

After verifying that the vehicle’s heated or ventilated seats will not turn on after a remote start has been initiated, check the vehicle’s personalization menu to see if these options have been enabled. The heated and ventilated seats both have to be selected independently in order for each to operate.

To turn on both options, navigate to the Vehicle Settings > Climate and Air Quality menu and select both the Remote Start Auto Cool Seat option and Remote Start Auto Heat Seat option. (Or, they may be found under the Comfort and Convenience menu.)

The system uses the information obtained from the Outside Ambient Temperature sensor on the vehicle. When it reads 27°C or higher, it will allow the operation of the ventilated seats during a remote start. When it reads 10°C or lower, the system will allow operation of the heated seat during a remote start. If the sensor reads anything in between these temperatures, neither the heated nor ventilated seats will turn on regardless if they are enabled in the personalization menu.

Climate Control & Heated/Cooled Seat Operation During a Remote Start

Climate Control (HVAC) Settings
During a remote start, the HVAC settings will operate at the previous HVAC settings when the vehicle was last turned off. If the owner desires a certain HVAC setting during a remote start, the HVAC mode, blower and temperature should be set prior to turning off the truck.

Rear Window Defogger
During a remote start, the rear window defogger will turn on if the outside temperature is 7°C or below. It will stay on for 10 minutes when the key is turned to Run/On. The rear window defogger indicator will not be illuminated until the key is turned to Run/On.

Heated Seats
During a remote start, the heated seats will turn on (if enabled) to the high setting when the ambient temperature is below 10°C. They will turn off when the key is turned to Run/On. The heated seat indicators will not be illuminated when the heated seats are on during a remote start. To enable the heated seats to operate during a remote start, go to the Vehicle Settings menu.

Cooled Seats
During a remote start, the cooled seats will turn on (if enabled) to the high setting when the ambient temperature is above 27°C. They will turn off when the key is turned to Run/On. The cooled seat indicators will not be illuminated when the cooled seats are on during a remote start. To enable the cooled seats to operate during a remote start, go to the Vehicle Settings menu.

Heated Steering Wheel
During a remote start the heated steering wheel does not turn on.

Memory Seat Operation

Memory Seat Buttons

The available memory seat system on certain GM vehicles provides the convenience of remembering the desired (stored) position of the driver’s seat and outside mirrors, and adjusting the seat and mirrors to that position upon demand. *(The gas and brake pedal positions may also be adjusted on vehicles equipped with adjustable pedal controls, often located on the bottom left of the center control console} This may be performed manually using the memory buttons or automatically when either the ignition is turned on or when the driver’s door is unlocked and opened with the Remote Keyless Entry (RKE) transmitter (key fob) present.

Memory Seat Operation

The memory seat system performs Memory Seat Recall and Easy Exit functions. These functions can be operated manually or automatically. The automatic recall operation can be enabled by the customer in the vehicle’s Comfort and Convenience menu settings. Automatic recalls can be provided upon Ignition On or Door Open/Unlock.

TIP: If the Door Open/Unlock setting is selected, the driver’s door must also be unlocked for the automatic recall feature to operate.

The infotainment system reports the automatic memory recall option settings to the seat’s Memory Seat Module as well as other receiving modules via serial data messages. The module stores the memory recall option settings that control its automatic memory recall operations.

Wireless Charging Pad

The vehicle may have a dock spot for wireless charging on top of the center console. The system wirelessly charges one PMA or QI compatible mobile device.

*To check for phone or other device wireless charging compatibility, see: http://www.gmtotalconnect.ca/assets/pdf/GM_Wireless_Charging_Compatible_Device_USE_andCAE.pdf

From Wikipedia Nov. 2014

Power Matters Alliance (PMA) is a global, not-for-profit, industry organization whose mission is to advance a suite of standards and protocols for wireless power transfer. Founded by Procter & Gamble and Powermat Technologies in March 2012, PMA is networking technology companies in order to guarantee consumers interoperable devices which employ wireless power technology. Marked by the electron “P”, PMA interface standard describes analog power transfer (inductive and resonant), digital transceiver communication, cloud based power management, and environmental sustainability. The PMA board of directors includes representatives from AT&T, Duracell, Starbucks, Powermat Technologies, Flextronics, Federal Communications Commission (FCC), and Energy Star. The membership of the PMA is made up of companies across the mobile device ecosystem, including handset providers, service providers, chipset suppliers, manufacturers, test labs and public establishments.

Qi (pronounced CHEE) is an interface standard developed by the Wireless Power Consortium for inductive electrical power transfer over distances of up to 4cm. The Qi system comprises a power transmission pad and a compatible receiver in a portable device. To use the system, the mobile device is placed on top of the power transmission pad, which charges it via resonant inductive coupling

Mobile device manufacturers that are working with the Qi standard include Asus, HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, BlackBerry, and Sony

Hill Descent Control / Integrated Trailer Brake Control / Trailer Sway Control

Hill Descent Control

Hill Descent Control (HDC) sets and maintains vehicle speed while descending a very steep decline in a forward or reverse gear. Press the HDC switch on the center of the instrument panel to enable or disable HDC. Vehicle speed must be less than 50km/h. The HDC light displays on the instrument cluster when enabled.

2015 Chevrolet Silverado HD

HDC can maintain vehicle speeds between 3 and 22km/h on an incline greater than or equal to a 10% grade. A blinking HDC light indicates the system is actively applying the brakes to maintain vehicle speed.

When HDC is activated, the initial HDC speed is set to the current driving speed. It can be increased or decreased by applying the accelerator or brake pedal. This adjusted speed becomes the new set speed. HDC will remain enabled between 22 and 60km/h; however, vehicle speed cannot be set or maintained in this range. It will automatically disable if the vehicle speed is equal to or greater than 80km/h, or more than 60 km/h for at least 30 seconds. Press the HDC switch again to re-enable HDC.

Integrated Trailer Brake Control

New for 2015 HD trucks, the Integrated Trailer Brake Control is now compatible with electric over hydraulic trailer brakes. The Integrated Trailer Brake Control system can be used to adjust the amount of power output, or Trailer Gain, available to the trailer brakes. The control panel also allows manual application of the trailer brakes.

Trailer Sway Control

Trailer Sway Control will detect any vehicle yaw (rotation) instability, caused by unintended side-to-side motion of a trailer while being towed. If sway is detected, the vehicle brakes are selectively applied at each wheel to help reduce excessive trailer sway. The engine torque also may be reduced to slow down the vehicle.

Exhaust Brake

CNG 2500HD


The new 2015 Silverado 2500HD and Sierra 2500HD pickup trucks feature bi-fuel gasoline/CNG operation. The operation of the bi-fuel gasoline/CNG 6.0L V8 engine (RPO LC8) is very similar to past model years. For 2015, there are new switches and Driver Information Center (DIC) messages. The 6.0L V8 engine is equipped with special hardened valves and valve seats to enable operation on gasoline or compressed natural gas (CNG).

CNG Indicator Lamp

2015 Silverado 2500HD Bi-Fuel

The CNG fuel selector switch indicator on the center of the instrument panel shows the current fuel mode, indicates a transition between fuels and if there is a system error.

  1. OFF: Vehicle is currently operating on gasoline.
  2. ON: Vehicle is currently operating on CNG.
  3. Flashing Slowly (Once per Second): Vehicle is awaiting changeover to selected fuel or has started the changeover.
  4. Flashing Rapidly (10 Times per Second): CNG system error. The light will continue to flash rapidly until the problem is corrected.

CNG Fuel Selector Switch

Regardless of which fuel mode is selected, gasoline or CNG, the vehicle always starts on gasoline. When the ignition is in ON/RUN, press the CNG fuel selector switch to select gasoline or CNG. When CNG mode is selected, the vehicle will automatically transition from gasoline to CNG when conditions for CNG operation have been met. While waiting to transition, the fuel selector switch indicator will flash. At temperatures colder than 0°C, it may take 10 to 15 minutes for the vehicle to switch from gasoline to CNG.

If operating in CNG mode and the CNG tank is emptied, the vehicle will automatically switch to gasoline operation and the switch indicator will flash continuously. Press the CNG fuel selector switch to stop the indicator flashing. Always keep the gasoline tank adequately filled. The system will not switch over to CNG operation if the vehicle runs out of gasoline.

TIP: If the vehicle is heavily loaded, such as when towing a trailer up a grade, it may be prevented from switching to CNG. Once the high loads are no longer present, the system will switch.

Fuel Gauge Operation

2015 Silverado 2500HD Bi-Fuel

Regardless of which fuel mode is selected, gasoline or CNG, the vehicle always starts on gasoline. When the ignition is in ON/RUN, press the CNG fuel selector switch to select gasoline or CNG. When CNG mode is selected, the vehicle will automatically transition from gasoline to CNG when conditions for CNG operation have been met. While waiting to transition, the fuel selector switch indicator will flash. At temperatures colder than 0°C, it may take 10 to 15 minutes for the vehicle to switch from gasoline to CNG.

CNG Fuel Tank

There are two methods of refueling: fast filling or slow filling. Fast filling is normally used in fuel stations for natural gas vehicles. It takes about six to eight minutes to fill up the fuel tank. Slow filling is done with a vehicle refueling appliance or a time-fill post provided by the fleet operator. Refueling time varies depending upon the refueling system used.

Turn off the engine prior to refilling. Remove the dust cap from the fuel fill valve/receptacle, clean off any dirt or debris on the fuel fill valve/receptacle, and follow the refueling instructions on the pump or provided by the station operator. Refueling will stop automatically when the tank is full. Wait for the high pressure fuel to be purged from the hose before disconnecting.

To disconnect the vehicle from the refueling station, remove the nozzle from the fuel fill valve/receptacle. A hissing sound may be heard as a small amount of natural gas escapes. This is normal. Put the fill valve dust cap on securely and close the fuel fill door.

Valet Mode - Infotainment Lockout


Valet Mode Infotainment Lockout
(If Equipped, model year 2014 and up)
