There are several ways to lock and unlock your vehicle. Use your key to lock and unlock your vehicle from the outside. If your vehicle is equipped with a remote keyless entry system, you can also use it to lock and unlock your vehicle. See Remote Keyless Entry System on page 2-3. To lock the door from the inside, push the locking lever forward. Power Door Locks If your vehicle has this feature, you can lock or unlock all the doors on your vehicle from the driver's or front passenger's door lock switch. Press the lower portion of the switch to lock the doors. Press the upper portion of the switch to unlock the doors. To unlock the door, pull the locking lever rearward. The locking lever on each rear door works only that door's lock. It will not lock or unlock all of the doors - that is a safety feature. 2-8
