Transmitter Verification This feature provides feedback that a command has been received by the keyless entry receiver. The headlamps and back-up lamps will flash on every lock and on the first unlock command. The horn will also sound once for every lock and twice for the first unlock command. Silent operation and other options may be selected for this feature. See Vehicle Personalization on page2-43. If your vehicle has the optional content theft-deterrent system, the first time the remote unlock is received, three flashes from the headlamps will be seen and chirps will be heard to indicate an alarm condition has occurred since last arming. See Content Theft-Deterrent on page 2-15. 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. If you prefer, you can complete this procedure yourself. See Vehicle Personalization on page 2-43 for more information. Illumination on Remote Activation The interior lamps will come on when either the UNLOCK, the trunk release or the panic alarm button is pressed. The interior lamps will remain on for 40 seconds or until the ignition is turned to ON or LOCK is pressed. Locking the doors with the power door locks will also cause the lamps to turn off. If a door is opened during the 40 second period, the interior lamps will remain on while the door is open. 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. 2-6
