Before your vehicle was shipped from the factory it was programmed in Mode 1. To determine the current mode or to change to a different mode, do the following: 1. Put an automatic transaxle in PARK (P) or a manual transaxle in REVERSE (R) with the parking brake engaged and turn the ignition to ON. 2. Press and hold LOCK on the power door lock switch for 10 seconds. Release the switch when you hear the chime. Rear Door Security Locks If your vehicle is a four-door model, it has rear door security locks that help prevent passengers from opening the rear doors from the inside. The switch is located on the inside of the rear door. 3. Count the number of chimes you hear. The number of chimes tells you which mode your vehicle is in. You can change the mode by pressing and holding LOCK on the power door lock switch (two chimes for Mode 2, three chimes for Mode 3 and four chimes for Mode 4). 4. Repeat Step 2 until you hear the number of chimes that matches the mode you want. The mode you selected is now set. To use the security locks, do the following: 1. Move the switch up. 2. Close the door. 3. Do the same thing to the other rear door. 2-10
