Remote Lock/Unlock Confirmation (If Equipped) (Remote Lock/Unlock Confirmation): Press this button to use this feature, if equipped, this feature provides feedback to the holder of the remote keyless entry transmitter that a command has been received by the keyless entry receiver. To signal that a command has been received, the headlamps will flash and the horn may sound briefly. To program the various modes available, see "Locks and Lighting Choices" in the Index. Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about three 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, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. 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. 2-12
