If the immobilizer system does not recognize the electronic code when the key is turned to START, the engine will not start and the security indicator will continue blinking. If your key is ever damaged, you may not be able to start your vehicle. When trying to start the vehicle, if the engine does not start and the security light continues flashing, there may be a problem with the theft-deterrent system. Turn the ignition off and try again. If the engine still does not start, and the key appears to be undamaged, try another key. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers on page 5-89. 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/retailer who can have a new key made. Up to five keys may be programmed for the vehicle. If you lose or damage your keys, only a dealer/retailer can have new keys made. In an emergency, contact Roadside Assistance. See Roadside Assistance Program on page 7-8. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. Starting and Operating Your Vehicle New Vehicle Break-In Notice: Your vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: • Do not drive at any one constant speed, fast or slow, for the first 500 miles (805 km). Do not make full-throttle starts. Avoid downshifting to brake or slow the vehicle. • Avoid making hard stops for the first 200 miles (322 km) or so. During this time the new brake linings are not yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-in guideline every time you get new brake linings. Following break-in, engine speed and load can be gradually increased. 2-17
