The remote control door lock receiver system allows the driver to use a hand-held transmitter in order to perform the following functions:

    • Unlock the driver's door
    • Unlock all of the doors
    • Lock all of the doors
    • Release the rear compartment lid

The range of the transmitter is approximately 7 meters (23 feet). If the transmitter's range decreases, replace the battery in the transmitter. Refer to Transmitter Battery Replacement .

The maximum range of the transmitter is dependent upon ambient conditions as well as other operating parameters. Under some conditions, the transmitter's range may be less than normal, or the receiver may not operate, due to interference from anonymous radio transmissions. Attach the door lock key (oval head) (4) to the key ring on the transmitter. The key will be available, if the receiver does not operate.

If you unlock the driver's door or release the rear compartment lid using the transmitter, the interior lamps light. The lamps remain lit for approximately 40 seconds, or until the ignition switch is turned to the RUN position.

This vehicle has door jamb switches on the front doors. A switch, mounted on the door handle, controls the interior lamps. Two-door and 4-door models use the door jamb switches on the front and rear doors in order to control the interior lamps, if a rear door is open. The multifunction module controls the interior lamps when any door is opened. The remote control door lock receiver lights the interior lamps if you press the unlock button (2) or the rear compartment lid release button (3) on the transmitter.
