Pressing this button once will unlock the driver's door. The parking lamps will flash twice and the interior lamps will turn on. Press UNLOCK again within five seconds to unlock the remaining doors. The parking lamps will flash. The remote keyless entry transmitter comes equipped with an instant panic alarm. To use the alarm, press the horn symbol when the ignition is turned off. The horn will sound and both the interior and exterior lamps will flash for up to thirty seconds. To stop the instant panic alarm, press the panic button again, wait for thirty seconds, or start the vehicle. & (Unlock): 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. & (Panic Alarm): f 4 (Cargo Door): Press this button to unlock the cargo doors only. Resynchronization Resynchronization may be necessary due to the security method used by this system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. To resynchronize your transmitter, stand close to your vehicle and press and hold the LOCK and UNLOCK buttons on the transmitter at the same time for seven seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle, see your dealer for service. 2-5
