Personalization Features

The following list of features available on your vehicle can be programmed to the driver's preference for each transmitter.

    • Automatic Door Locks: This feature programs your door locks to automatically lock or unlock when shifting in and out of PARK (P) or when the key is turned to OFF.
    • Security Feedback: This feature provides feedback to the driver when the vehicle receives a command from the remote keyless entry transmitter.
    • Delayed Locking: This feature lets the driver delay the actual locking of the vehicle. When all doors have been closed, the doors will lock automatically after five seconds.
    • Perimeter Lighting: When the unlock symbol on the remote keyless entry transmitter is pressed, the Daytime Running Lamps (DRL), parking lamps and back-up lamps will turn on if it is dark enough outside.

For more detailed information and programming instructions for each feature mentioned, refer to DIC Vehicle Personalization .

Security Feedback

This feature provides feedback to the driver when the vehicle receives a command from the remote keyless entry transmitter and all doors are closed.

You must program this feature through the Driver Information Center (DIC). See DIC Vehicle Personalization .

The following settings can be programmed for each of the remote keyless entry transmitters:

    • No feedback when locking or unlocking vehicle.
    • Parking lamps and the Daytime Running Lamps (DRL) will flash twice when unlocking the vehicle and flash once when locking the vehicle.
    • Horn chirps when all doors are unlocked (second unlock button press) and when locking the vehicle.
    • Parking lamps and the DRL will flash twice each time the button with the unlock symbol is pressed; the horn chirps when all doors are unlocked. Parking lamps and the exterior lamps flash once and the horn chirps when locking the vehicle.

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of four transmitters matched to it.

See your dealer to match transmitters to another vehicle.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about four years.

You can tell the battery is weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the battery.

Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.

To replace the battery, do the following:

  1. Insert a coin, or similar object, into the notch near the key ring. Turn it counterclockwise to separate the two halves of the transmitter.
  2. Once the transmitter is separated, use a pencil eraser to remove the old battery. Do not use a metal object.
  3. Replace the battery as the instructions under the cover indicate. Use a Duracell® battery, type DL-2032, or a similar type.
  4. Snap the transmitter back together tightly to be sure no moisture can enter.
  5. Check the operation of the transmitter.
