GMC Terrain: Setting Adaptive Cruise Control / 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.
See Roof Rack System.
Do not modify the hood, headlamps,
or fog lamps, as this may limit the
camera’s ability to detect an object.
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...
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...
