GMC Terrain: Setting Adaptive Cruise Control / Other Vehicle Lane Changes

ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a
vehicle exiting or entering exit
ramps...
The detection of objects in front of
the vehicle may not be possible if:
The vehicle or object ahead is
not within your lane.
The vehicle ahead is shifted, not
centered, or is shifted to one
side of the lane...
Other information:
If the ignition is on or in ACC/
ACCESSORY and the power door
lock switch is pressed with the
driver door open, all the doors will
lock and only the driver door will
unlock.
If the vehicle is off and locking is
requested while a door is open,
when all doors are closed the
vehicle will check for RKE
transmitters inside...
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...
