GMC Terrain: Setting Adaptive Cruise Control / Lighting Conditions Affecting ACC

The ACC front camera can be affected by poor lighting conditions, and ACC may have limited performance when:

  • There are changes in brightness, such as entering and exiting tunnels, bridges, and overpasses.
  • Low sun angles cause the camera to not detect objects, or it is more difficult to detect objects in the same traffic lane.
  • Lighting is poor in the evening or early morning
  • There are multiple changes in brightness or shadows along the vehicle roadway.
  • In a tunnel without the headlamps on, or in a tunnel when there is a vehicle in front that does not have its taillamps on.
  • Subjected to strong light from opposing lane traffic in the front of the vehicle, such as high-beam headlamps from oncoming traffic.

    Weather Conditions Affecting ACC

    If the interior temperature is extremely high, the instrument cluster may indicate that ACC is temporarily unavailable. This can be caused by extreme hot weather conditions with direct sunlight on the front camera...

    Accessory Installations and Vehicle Modifications

    Do not install or place any object around the front camera windshield area that would obstruct the front camera view. Do not install objects on top of the vehicle that overhang and obstruct the front camera, such as a canoe, kayak, or other items that can be transported on a roof rack system...
