Remote Keyless Entry System Operation If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle. Q (Lock): Press lock to lock all the doors. Press lock again within three seconds and the horn will chirp. L (Panic): Press the horn symbol to make the horn sound. The headlamps and taillamps will flash for up to 30 seconds. This can be turned off by pressing the horn button again, by waiting for 30 seconds, or by starting the vehicle. K (Unlock): Press unlock for the driver's door to unlock automatically, the parking lamps to flash and the interior lights to go on. Press the unlock button a second time within three seconds to unlock all the doors. 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. You can program different feedback settings through the Driver Information Center (DIC). For more information see Driver Information Center (DIC) on page 3-50. 2-6
