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:
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See Traction
Control/Electronic Stability Control...
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working...
