Resynchronization After replacing the battery in your transmitter, or if only the instant alarm works, the transmitter needs to be resynchronized to the receiver. Do this by pressing and holding both the button with the lock symbol and the button with the unlock symbol at the same time for about eight seconds. You must be within range of the vehicle. Once the transmitter has been resynchronized, the horn will chirp and the exterior lamps will flash once. The system should now operate properly. 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 RECIRC. 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. 2-16
