VEHICLE PERSONALIZATION
PROGRAMMABLE AUTOMATIC DOOR LOCKS (IF EQUIPPED)
If the vehicle has power door locks, it is equipped with a feature that enables you to program the power door locks.
The vehicle left the factory programmed to automatically lock all doors when the vehicle is shifted out of PARK (P), and all doors unlock when the vehicle is shifted into PARK (P).
If the vehicle has a manual transmission it left the factory programmed to lock all doors when the vehicle speed is greater than 13 km/h (8 mph) for two seconds, and unlock all doors once the key is removed from the ignition.
The following instructions detail how to enter the programming mode for the power door lock feature:
1. Begin with the ignition OFF. Then pull the signal/multifunction lever all the way toward you and hold it there while you perform the next step.
2. Turn the key to RUN and LOCK twice. Then, with the key in LOCK, release the turn signal/multifunction lever. Once you do this you will hear the lock switch lock and unlock, the horn will chirp twice and a 30 secondprogram timer will begin.
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 30 seconds to complete programming. If you exceed the 30 second limit, 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, repeat the procedure beginning with step 1. You can exit the program mode any time by turning the ignition to RUN. If the LOCK/UNLOCK switches are not pressed while in the programming mode, the current LOCK/UNLOCK mode will not be modified.
The following is a list of available programming options:
- All doors lock when the transmission is shifted into gear: Press the lock side of the power door lock switch on the door panel once.
- All doors lock when the vehicle speed is greater than 13 km/h (8 mph): Press the lock side of the power door lock switch on the door panel twice.
- No automatic door locking: Press the lock side of the power door lock switch on the door panel three times.
- Driver's door unlocks when the transmission is shifted into PARK: Press the unlock side of the power door lock switch on the door panel once.
- All doors unlock when the transmission is shifted into PARK: Press the unlock side of the power door lock switch on the door panel twice.
- All doors unlock when the key is removed from the ignition: Press the unlock side of the power door lock switch on the door panel three times.
