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:
This feature delays the actual
locking of the doors until
five seconds after all doors are
closed.
Delayed locking can only be turned
on when the Open Door
Anti-Lockout feature has been
turned off.
When is pressed on the power
door lock switch with the door open,
a chime will sound three times
indicating that delayed locking is
active...
Warning
If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.
Always push and pull on the
seatbacks to be sure they are
locked.
Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash...
