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. Normally, the transmitter and receiver resynchronize automatically. However, under certain circumstances, manual resynchronization may be required. 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 10 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. Doors and Locks Door Locks {CAUTION: Unlocked doors can be dangerous. • Passengers - especially children - can easily open the doors and fall out of a moving vehicle. When a door is locked, the handle will not open it. You increase the chance of being thrown out of the vehicle in a crash if the doors are not locked. So, wear safety belts properly and lock the doors whenever you drive. • Young children who get into unlocked vehicles may be unable to get out. A child can be overcome by extreme heat and can suffer permanent injuries or even death from heat stroke. Always lock your vehicle whenever you leave it. • Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. Locking your doors can help prevent this from happening. 2-7
