Programmable Automatic Door Locks Your vehicle may be equipped with an automatic lock/unlock feature which enables you to program your vehicle's power door locks. You can program this feature through the Driver Information Center (DIC), or by the following method. See DIC Vehicle Customization on page 3-64. To enter the program mode, do the following: 1. Begin with the ignition off. Then pull the turn signal/multifunction lever toward you and hold it there while you perform the next step. 2. Turn the key to RUN then back to LOCK twice. Then, with the key in LOCK, release the turn signal/multifunction lever. Once you do this, the doors will lock and unlock, the horn will chirp twice, and a 30-second timer will begin. You are now ready to program the automatic door lock feature. 3. Press the door lock switch once. You will hear either one or two chimes. The number of chimes tells you which lock mode is currently selected. Continue to press the door lock switch until the number of chimes that you hear matches the number of the mode that you want. If you take longer than 30 seconds, the locks will automatically lock and unlock and the horn will chirp twice to indicate that you have left the program mode. If this occurs, you can repeat the procedure beginning with Step 1 to re-enter the programming mode. You can exit the program mode any time by turning the ignition to RUN (the doors will automatically lock and unlock and the horn will chirp twice to indicate that you are leaving the program mode). If the lock/unlock switches are not pressed while in the programming mode, the current automatic settings will not be modified. See your dealer for more information. Programmable Locking Feature Following are the two available programming options: Mode 1: All doors lock when the transmission is shifted into gear. This is the mode that is pre-programmed in the factory for your vehicle for automatic transmission vehicles. Mode 2: All doors lock when the vehicle speed is greater than 8 mph (13 km/h). This is the mode that is pre-programmed in the factory for manual transmission vehicles. The following instructions tell you how to change the automatic door lock mode (automatic transmission only). Choose one of the two programming options listed above before entering the program mode. 2-10
