Trunk CAUTION: It can be dangerous to drive with the trunk lid 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 trunk lid open or if electrical wiring or other cable connections must pass through the seal between the body and the trunk lid: 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 any airflow selection except MAX. 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. Resynchronization Your remote keyless entry system is equipped with a security system that prevents anyone from recording and playing back your signal. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent to it more than once. To resynchronize your transmitter and receiver, follow these directions: 1. Stand close to your vehicle. 2. Press and hold the LOCK and UNLOCK buttons on the transmitter at the same time. 3. Hold the buttons for at least five seconds. During this time, the doors should lock and unlock once. This confirms the resynchronization. If the doors do not lock and unlock, see your dealer for service. 2-10
