GMC Terrain: Setting Adaptive Cruise Control / Irregular Objects Affecting ACC
ACC may have difficulty detecting
the following objects:
- Vehicles in front of your vehicle
that have a rear aspect that is
low, small, or irregular
- An empty truck or trailer that has
no cargo in the cargo bed
- Vehicles with cargo extending
from the back end
- Non-standard shaped vehicles,
such as vehicle transport,
vehicles with a side car fitted,
or horse carriages
- Vehicles that are low to the road
surface
- Objects that are close to the
front of your vehicle
- Vehicles on which extremely
heavy cargo is loaded in the
cargo area or rear seat

Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a
vehicle it has never detected
moving...
ACC may automatically disengage
and the driver will need to manually
apply the brakes to slow the
vehicle if:
The front camera is blocked or
visibility is reduced...
Other information:
If ACC is engaged, driver action
may be required when ACC cannot
apply sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, six red
lights will flash on the windshield.
Either eight beeps will sound from
the front, or both sides of the Safety
Alert Seat will pulse five times...
To adjust the mirrors:
Press or
to choose the
driver or passenger mirror.
Press the arrows on the control
pad to move each mirror in the
desired direction.
