Power Door Locks Every vehicle with power door locks has a pulse lock system. A pulse lock system works like this: ' ' 'I If your vehicle has power door locks, press the power door lock switch to lock or unlock all the doors at once. If the sliding door is open arid you press 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 door locks. 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 The power door lock switch will not lock or unlock the rear hatch and Dutch doors. You must use the REAR HATCH button. See "Rear Hatch and Dutch Doors Release" in this section. 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. 2-6
