The operating mode of the programmable automatic power door locks will be changed when the driver performs the following: 1. Turn the ignition key to RUN. 2. Close all of the doors. 3. Apply your regular brakes. 4. Press and hold the power door lock switch. While holding the door lock switch, move the shift lever out of and back into PARK (P). After an initial transaxle cycle, each additional cycle will advance the operating mode by one, starting from the current operating mode. During this procedure, the automatic door lock and unlock functions will operate as defined by each mode listed previously, providing the driver with feedback of the current operating mode. If cycled beyond Mode 4, the vehicle will enter operating Mode 1. When the door lock switch is released, the vehicle will remain in the most recent operating mode. Disconnecting the vehicle's battery for up to a year will not change the programmed mode of the programmable automatic power door locks. Rear-Door Child Security Locks Your vehicle is equipped with rear-door child security locks that help prevent passengers from opening the rear doors of your vehicle from the inside. To use one of these locks: 1. Open one of the rear doors. 2. On the inside of the rear door will be a lock. Insert your key into this lock and turn it upward. This will engage the safety lock. To disengage the feature, turn the lock downward. 3. Close the door. 4. Do the same thing to the other rear door lock. The rear doors of your vehicle cannot be opened from the inside when this feature is in use. If you want to open the rear door when the security lock is on, unlock the door from the inside and then open the door from the outside. 2-6
