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:
Tires should be rotated every
12 000 km (7,500 mi). See
Maintenance Schedule.
Tires are rotated to achieve a
more uniform wear for all tires.
The first rotation is the most
important.
Anytime unusual wear is
noticed, rotate the tires as soon
as possible, check for proper tire
inflation pressure, and check for
damaged tires or wheels...
The exterior lamp control is on the
instrument panel to the left of the
steering column.
There are four positions.
: Turns the exterior lamps off
and
deactivates the AUTO mode. Turn
to again to reactivate the
AUTO mode.
In Canada, the headlamps will
automatically reactivate when the
vehicle is shifted out of P (Park)...
