GMC Terrain: Vehicle Security / Vehicle Alarm System

This vehicle has an anti-theft alarm system.

GMC Terrain. Vehicle Alarm System

The indicator light, on the instrument panel near the windshield, indicates the status of the system:

Off : Alarm system is disarmed.

On Solid : Vehicle is secured during the delay to arm the system.

Fast Flash : Vehicle is unsecured. A door, the hood, or the liftgate is open.

Slow Flash : Alarm system is armed.

Arming the Alarm System

  1. Turn off the vehicle.
  2. Lock the vehicle in one of two ways:
    • Use the RKE transmitter.
    • With a door open, press the interior GMC Terrain. Vehicle Alarm System.
  3. After 30 seconds the alarm system will arm, and the indicator light will begin to slowly flash indicating the alarm system is operating. Pressing GMC Terrain. Vehicle Alarm System on the RKE transmitter a second time will bypass the 30-second delay and immediately arm the alarm system.

The vehicle alarm system will not arm if the doors are locked with the key.

If the driver door is opened without first unlocking with the RKE transmitter, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing GMC Terrain. Vehicle Alarm System on the RKE transmitter during the 10-second pre-alarm, the alarm will be activated.

If a door, the hood, or the liftgate is opened without first disarming the system, the turn signals will flash and the horn will sound for about 30 seconds. The alarm system will then re-arm to monitor for the next unauthorized event.

Disarming the Alarm System

To disarm the alarm system or turn off the alarm if it has been activated:

  • Press GMC Terrain. Vehicle Alarm System on the RKE transmitter.
  • Start the vehicle.

To avoid setting off the alarm by accident:

  • Lock the vehicle after all occupants have left the vehicle and all doors are closed.
  • Always unlock a door with the RKE transmitter.

Unlocking the driver door with the key will not disarm the system or turn off the alarm.

How to Detect a Tamper Condition

If GMC Terrain. Vehicle Alarm System is pressed on the RKE transmitter and the horn chirps and the lights flash three times, an alarm occurred previously while the alarm system was armed.

If the alarm has been activated, a message will appear on the Driver Information Center (DIC).
