There are several ways to lock and unlock your vehicle. If your vehicle has a content theft-deterrent system, unlock the doors only with the key or remote keyless entry system. This will avoid setting off the alarm. To unlock the door from the outside, use your door key or remote keyless entry transmitter. Turning the door key toward the front of the vehicle will lock the door. Turning the door key toward the rear of the vehicle will unlock it. Central Door Unlocking System If your vehicle has a theft-deterrent system, all doors will unlock if the key is held in the outside key cylinder unlock position for more than two seconds. The doors will also unlock if the key is turned to the unlock position twice in three seconds. Power Door Locks With power door locks, you can lock or unlock all the doors on your vehicle. The power door lock switches are located on the driver's and front passenger's door panels. To unlock the door from the inside, move the manual door lock, located above the door handle, rearward. To lock the door, move the manual door lock forward. 2-10
