GMC Terrain: Keys and Locks / Door Locks
Warning
Unlocked doors can be
dangerous.
- Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. The doors
can be unlocked and
opened while the vehicle is
moving. The chance of
being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all
passengers should wear
seat belts properly and the
doors should be locked
whenever the vehicle is
driven.
- Young children who get into
unlocked vehicles may be
unable to get out. A child
can be overcome by
extreme heat and can suffer
permanent injuries or even
death from heat stroke.
Always lock the vehicle
whenever leaving it.
- Outsiders can easily enter
through an unlocked door
when you slow down or stop
the vehicle. Locking the
doors can help prevent this
from happening.

outside the vehicle:
- Press
or
on the Remote
Keyless Entry (RKE) transmitter.

inside the vehicle:

Warning
If something is carried on top of
the vehicle that is longer or wider
than the roof rack—like paneling,
plywood, or a mattress—the
wind can catch it while the vehicle
is being driven. The item being
carried could be violently torn off,
and this could cause a collision
and damage the vehicle...
According to accident statistics,
children and infants are safer when
properly restrained in an appropriate
child restraint secured in a rear
seating position.
Whenever possible, children aged
12 and under should be secured in
a rear seating position...
