GMC Terrain: Setting Adaptive Cruise Control / Cleaning the Sensing System
The camera sensor on the windshield behind the rearview mirror can become blocked by snow, ice, dirt, mud, or debris. This area needs to be cleaned for ACC to operate properly.
The vehicle headlamps may need to be cleaned due to dirt, snow, or ice. Objects that are not illuminated correctly may be difficult to detect.
If ACC will not operate, regular cruise control may be available. See “Switching Between ACC and Regular Cruise Control” in this section. Always consider driving conditions before using either cruise control system.
For cleaning instructions, see “Washing the Vehicle” under Exterior Care.
