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...
Other information:
The Diesel Particulate Filter (DPF)
system filters soot particles out of
the exhaust gases. The DPF is
under the vehicle in the exhaust
system.
Depending on a number of factors
monitored by the engine computer,
the DPF will need to be cleaned of
accumulated solids...
The engine air cleaner/filter is in the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment Overview.
When to Inspect the Engine Air Cleaner/Filter
For intervals on changing and
inspecting the engine air cleaner/filter, see Maintenance Schedule...
