If your vehicle has this power door lock switch, press the bottom of the switch on either front door to lock all the doors at once. Programmable Automatic Door Locks Your vehicle is equipped with an auto lock/unlock feature which enables you to program your power door locks. Your vehicle left the factory programmed to have the automatic lock feature lock all the doors when the vehicle speed is greater than 15 mph (24 km/h) for two seconds, and then unlock all the doors once the key is removed from the ignition. The following instructions detail how to program your door locks. To enter the program mode you need to do the following: 1. Beginning with the ignition in OFF, pull back on the turn signal/multifunction lever all the way toward you and hold it while you perform the next step. 2. Turn your key to ON and OFF twice. Then, with the key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock switch lock and unlock. 3. You are now ready to program the automatic door locks. Select one of the following four programming options and follow the instructions. You will have ten seconds to begin programming. If you exceed the ten second limit, the locks will automatically lock and unlock to indicate you have left the program mode. Press the top of the switch to unlock all the doors at once. The power door locks will operate at any time without the ignition being on. The power door locks will also automatically lock when the vehicle reaches 15 mph (24 km/h). To unlock the doors, refer to the instructions listed previously. The automatic locking feature can be disabled, if you prefer. See "Programmable Automatic Door Locks" in the following text. Operating the power locks may interact with the theft-deterrent system (if equipped). See "Content Theft-Deterrent" in the Index. 2-8
