GMC Terrain: Setting Adaptive Cruise Control / Weather Conditions Affecting ACC
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. ACC will return to
normal operation once the cabin
temperature is lower.
Conditions that are associated with
low visibility, such as fog, rain,
snow, or road spray, may limit ACC
performance. Water droplets from
rain or snow that remain on the
windshield may also limit ACC’s
ability to detect objects.
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...
Other information:
Warning
The power seats will work with
the ignition off. Children could
operate the power seats and be
injured. Never leave children
alone in the vehicle.
To adjust a power seat, if equipped:
Move the seat forward or
rearward by sliding the control
forward or rearward...
In addition to notifying NHTSA (or
Transport Canada) in a situation like
this, notify General Motors.
