GMC Terrain: Keys and Locks / Automatic Door Locks
The doors will lock automatically
when all doors are closed, the
ignition is on, and the vehicle is
shifted out of P (Park).
If a vehicle door is unlocked and
then opened and closed, the doors
will lock either when your foot is
removed from the brake or the
vehicle speed becomes faster than
13 km/h (8 mph).
To unlock the doors:
- Press
on the power door
lock
switch.
- Shift into P (Park).
Automatic door locking cannot be
disabled. Automatic door unlocking
can be programmed. See Vehicle
Personalization.
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...
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...
Other information:
If the ACC is set at a desired speed
and then the brakes are applied,
ACC is disengaged without erasing
the set speed from memory.
To begin using ACC again, press
RES+ briefly while moving more
than 5 km/h (3 mph). The vehicle
returns to the previous set speed...
