Programmable Automatic Door Locks (If Equipped) If your vehicle has power door locks, it is equipped with a feature that enables you to program the door locks. Your vehicle left the factory programmed to automatically lock all doors when the vehicle is out of PARK (P), and all doors unlock when the vehicle is in PARK (P). You can set the automatic door lock feature to unlock the doors you select once the vehicle is in PARK (P). If your vehicle has a manual transmission it left the factory programmed to lock all doors when the vehicle speed is greater than 15 mph (24km/h) for two seconds, and unlock all doors once the key is removed from the ignition. You can set the automatic door lock feature to unlock the doors you select 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 until flash-to-pass is activated, and hold it while you perform the next step. 2. Turn your key to RUN and OFF twice. Then, with the key in OFF, release the turn signal/multifunction lever. Once you do this, you will hear the lock mechanism 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 thirty seconds to complete programming. If you exceed the thirty-second limit, the locks will automatically lock and unlock to indicate you have left the program mode. If this occurs, repeat the procedure beginning with Step 1. You can exit the program mode any time by turning the ignition to RUN (the locks will automatically lock and unlock to indicate you are leaving the program mode.) If the lock/unlock switches are not pressed while in the programming mode, the automatic lock/unlock setting will not be modified. 2-9
