There are several ways to lock and unlock your vehicle.
If your vehicle has a theft - deterrent system and it is
activated, unlock the doors only with the key or remote
keyless entry system. This will avoid setting off the
alarm. See “Universal Theft
- Deterrent” in the Index for
more information.
To unlock the door from the outside, use your door key
or remote keyless entry transmitter (if equipped).
Turning the door key toward the rear of the vehicle will
unlock the door. Turning the door key toward the front
of the vehicle will lock it.
To lock the door from the inside, push the manual door
lock forward. To unlock the door, push the manual door
lock rearward.
