Trailering App

If equipped, the Trailering App is on the Home Page of the infotainment display.

If equipped this feature allows profiles for connected trailers to be created to view status, to store and track trailer usage information, and to set up towing assistance features.

The Trailering App Preview will appear when the Trailering App is opened for the first time from the Home Page. Touch GET STARTED in the Trailering App to go into the app.

When a trailer is electrically connected, there will be an option to create a profile, use a guest profile, or cancel. After Cancel is selected a third time, Don’t Remind Me will display and touching that will turn off the trailer detection pop-up. To turn the Trailer Detection Alert on, select ON in the Settings tab.

When a trailer is electrically connected and after a Trailer Profile has been created, the trailer detection pop-up will appear with a list of all of the custom Trailer Profiles made on the vehicle. To load an existing Trailer Profile, select one of the Trailer Profiles listed, or load the Guest Trailer Profile by selecting GUEST TRAILER. Touching Cancel, Accessory/No trailer, or shifting the vehicle from P (Park), will select Accessory/No trailer as the active Trailer Profile and will dismiss the pop- up.

Create a Trailer Profile

  1. Touch Create Profile on the pop-up or touch + Add Trailer in the Trailering App.
  2. Create a name for the trailer.
  3. Select the hitch type. A checklist profile will be created based on the type selected.
  4. Select the trailer type.

A pop-up will indicate the setup is complete. Touch DONE to complete the process or touch TRAILER FEATURE SETUP to set up the Tow/Haul Mode reminder, Trailer Tire Pressure Monitoring System, if equipped, maintenance reminders, or towing assistance, if equipped.

Import a Trailer Profile

A trailer profile saved to an OnStar account can be imported to the vehicle.

  2. Select a trailer profile from the list.
  3. Touch IMPORT.

A pop-up will indicate the import was successful. Touch OK to return to the trailer list and select the trailer profile. The Tow/Haul Mode reminder, Brake Gain Setting and Trailer Tire Pressure sensor learning, if equipped, do not import.

Trailer Feature Setup

Tow/Haul Mode Reminder

To turn the Tow/Haul Mode Reminder setting on, touch Yes. To turn it off, touch No.

Trailer Tire Pressure Setup

If the Trailer Tire Pressure Monitoring System (TTPMS) is detected, touch the Tire Pressure Monitoring icon to set up tire pressure monitoring.Touch Yes to set up the sensors or touch No to return to the previous screen.

A trailer must be electrically connected to the vehicle before  starting the sensor-to-vehicle learn process.

After selecting Start from the Learn Sensors screen, use the Tool Method or the Manual Method (described below) to learn each tire sensor, during which the current tire number will be highlighted.

Each sensor has a minimum of two minutes to learn, shown by a timer. After a sensor is learned, a checkmark appears next to the tire, the vehicle horn will sound, the vehicle’s brake lamps will flash, and all working trailer lamps will flash. It then moves to the next sensor.

To cancel the process touch Stop.

The recommended tire pressure must be entered for the trailer tires. This allows the vehicle to alert when the tire pressure is high or low.

TTPMS must learn the location of the installed tire sensors to show correct air pressure and temperature for each tire. To set up, use one of the following options or see a tire or trailer dealer for service. The learning process must be repeated when the trailer tires are rotated or replaced. See “Editing a Trailer Profile” later in this section for tire pressure sensor relearn information.

Tool Method: A TTPMS activation tool can be purchased separately to learn the sensor locations.

Manual Method: Without the tool, the air pressure can be increased or decreased in each tire for 10 seconds. Do not exceed the maximum inflation pressure found on the tire sidewalls. Make sure to re-adjust tire pressure to the recommended level when the process is complete.

Sensor Learning Steps

To complete the sensor-to-vehicle learn process:

  1. Touch Start on the Learn Sensors screen. The horn chirps twice and the Learning Active screen appears on the infotainment display.
  2. Start with the driver side front trailer tire.
  3. Activate the tool near the valve stem or adjust the air pressure of this tire until the horn chirps and all working vehicle and trailer lights flash.

    The process stops without saving the sensor locations if this step takes more than two minutes.

  4. Move to the next tire and repeat Step 3 for each sensor. The horn chirps twice when all sensors are completed.
  5. Return to the vehicle to complete the setup.

Maintenance Reminders

To set up maintenance reminders, touch the Trailer Maintenance icon. Select Yes to set up the maintenance reminders for the Trailer Profile. Follow the on-screen prompts. The maximum number of reminders is 50. Select No to return to the previous screen.

Towing Assistance

Touch Yes to begin set up or touch No to return to the previous screen. Follow the on-screen instructions.

A rear trailer camera must be mounted on the trailer and electrically connected to the vehicle before transparent trailer feature can be used. See Assistance Systems for Parking or Backing.

Trailer dimensions must be in range and transparent trailer must be calibrated prior to use.
