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 it 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 simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for at least eight seconds. The door locks should cycle and the parking lamps and headlamps should flash to confirm synchronization. If this does not happen, you may need to replace the battery in your transmitter or match the transmitter to your vehicle. If the locks still do not cycle, see your dealer for service. Rear Doors CAUTION: It can be dangerous to drive with the tailgate glass, tailgate or rear doors open because carbon monoxide (CO) gas can come into your vehicle. You can't see or smell CO. It can cause unconsciousness and even death. If you must drive with the tailgate glass, tailgate or rear doors open or if electrical wiring or other cable connections must pass through the seal between the body and the tailgate glass, tailgate or rear doors: D Make sure all other windows are shut. D Turn the fan on your heating or cooling system to its highest speed with the setting on VENT. That will force outside air into your vehicle. See "Comfort Controls" in the Index. D If you have air outlets on or under the instrument panel, open them all the way. See "Engine Exhaust" in the Index. 2-11
