Power DoorLocks If your vehicle has power door locks, push the power door lock switch to lock or unlock all the doors at once. The power door lock switch will not lock or unlock the rear hatch and Dutch doors. You must use the HATCH REL switch. See "Rear Hatch and Dutch Doors Release'' in this section. Every vehicle with power door locks has a pulse lock system. A pulse lock system works like this: If the sliding dooris open and you push the power door lock switch, the sliding door will not lock immediately. After you close the door, the system comes on and,in about five seconds,locks the sliding door. All models have overriding doorlocks. When a door is locked, the door handle will not work the latch. This will help stop a door from being accidentally opened. However, power door locks do not affect the operation of the hatch. Leaving Your Vehicle If you are leaving the vehicle, take your keys, open your door and set the locks from inside. Then get out and close the door. Keyless Entry System If your vehicle has this option, you can lock and unlock your doors or hatch from up to 30 feet (9 m) away using the key chain transmitter supplied with your vehicle. Your Keyless Entry System operates on a radio frequency subject toFederal Communications Commission (FCC) Rules. 2- 10
