2007 Chevrolet Aveo Owner's Manual - Page 107

When trying to start the vehicle, if the engine does not start and the security light continues flashing, 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 key. At this time, you may also want to check the fuse. See Fuses and Circuit Breakers on page 356. 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 have a new key made. Up to five keys may be programmed for the vehicle. If you lose or damage your keys, only a GM dealer can have new keys made. If you are ever driving and the security light comes on and stays on, you will be able to restart your engine if you turn it off. The theft-deterrent system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the theft-deterrent system at this time. In an emergency, contact Roadside Assistance. See Roadside Assistance Program on page 408. 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 your 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. 107
