If the engine does not start and the security light comes on, there may be a problem with the immobilizer system. Press the START button again. If the vehicle does not start and the keyless access transmitter appears to be undamaged, try another keyless access transmitter. Or, place the transmitter in the transmitter pocket. See "NO FOBS DETECTED" under DIC Warnings and Messages on page 3-79 for additional information. Check the fuse. See Fuses and Circuit Breakers on page 5-123. If the engine still does not start with the other transmitter, the vehicle needs service. If the engine does start, the first transmitter may be faulty. See your dealer/retailer or have a new keyless access transmitter programmed to the vehicle. The immobilizer system can learn new or replacement keyless access transmitters. Up to four keyless access transmitters can be programmed for the vehicle. To program additional transmitters, see "Matching transmitter(s) to Your Vehicle" under Keyless Access System Operation on page 2-5. 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: The 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. • Do not tow a trailer during break-in. See Towing a Trailer (Vehicles Without Heavy Duty Cooling) on page 4-31 or Towing a Trailer (Vehicles With Heavy Duty Cooling) on page 4-32 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. 2-25
