This device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference. 2. This device must accept any interference received, including interference that may cause undesired operation of the device. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment. PASS-Key® III+ uses a radio frequency transponder in the key that matches a decoder in your vehicle. When the PASS-Key® III+ system senses that someone is using the wrong key, it prevents the vehicle from starting. Anyone using a trial-and-error method to start the vehicle will be discouraged because of the high number of electrical key codes. If the engine does not start and the security light on the instrument panel cluster comes on when trying to start the vehicle, the key may have a damaged transponder. Turn the ignition off and try again. If the engine still does not start, and the key appears to be undamaged, try another ignition key. At this time, you may also want to check the fuse, see Fuses and Circuit Breakers on page 400. If the engine still does not start with the other key, your vehicle needs service. If your vehicle does start, the first key may be faulty. See your dealer who can service the PASS-Key® III+ to have a new key made. In an emergency, contact Roadside Assistance. PASS-Key® III+ Operation Your vehicle has PASS-Key® III+ (Personalized Automotive Security System) theft-deterrent system. PASS-Key® III+ is a passive theft-deterrent system. This means you do not have to do anything special to arm or disarm the system. It works when you transition the key to RUN, ACCESSORY or START from the OFF position. 109
