2-18 Keys, Doors, and Windows If the vehicle does not start and the security light stays on, there is a problem with the system. Turn the vehicle off and try again. If the RKE transmitter appears to be undamaged, try another transmitter, or place the transmitter in the transmitter pocket. See "Starting the Vehicle with a Low Transmitter Battery" under Remote Keyless Entry (RKE) System Operation on page 2-3. If the vehicle does not start with the other transmitter or when the transmitter is in the transmitter pocket, your vehicle needs service. See your dealer who can service the theft-deterrent system and have a new transmitter programmed to the vehicle. Do not leave the transmitter or device that disarms or deactivates the theft-deterrent system in the vehicle. The immobilization system is disarmed when the ignition button is pushed in and a valid transmitter is found in the vehicle. Exterior Mirrors Convex Mirrors { Warning A convex mirror can make things, like other vehicles, look farther away than they really are. If you cut too sharply into the right lane, you could hit a vehicle on the right. Check the inside mirror or glance over your shoulder before changing lanes. The passenger side mirror is convex shaped. A convex mirror's surface is curved so more can be seen from the driver seat. The security light on the instrument cluster comes on when there is a problem with arming or disarming the theft-deterrent system. The system has one or more transmitters matched to an immobilizer control unit in the vehicle. Only a correctly matched transmitter will start the vehicle. If the transmitter is ever damaged, you may not be able to start your vehicle. When trying to start the vehicle, the security light comes on briefly when the ignition is turned on.
