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.
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...
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...
Other information:
This vehicle is equipped with
airbags. See Airbag System.
Airbags are designed to inflate if the
impact exceeds the specific airbag
system's deployment threshold.
Deployment thresholds are used to
predict how severe a crash is likely
to be in time for the airbags to
inflate and help restrain the
occupants...

The Brake Assist feature is
designed to assist the driver in
stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the

control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
