Passlock®

Your vehicle is equipped with the Passlock® theft-deterrent system.

Passlock® is a passive theft-deterrent system. Passlock® enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled.

During normal operation, the SECURITY light will

go off approximately five seconds after the key is turned to RUN.

If the engine stalls and the SECURITY light flashes, wait about 10 minutes until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

If the engine does not start after three tries, the vehicle needs service.

If the engine is running and the SECURITY message comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock® system is not working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock® at this time. You may also want to check the fuse.

See Fuses and Circuit Breakers on page 5-97. See your dealer for service.

In an emergency, call the GM Roadside Assistance Center. See Roadside Assistance Program on page 7-6.

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:

•Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km).

•Do not drive at any one speed — fast or

slow — for the first 500 miles (805 km). Do not make full-throttle starts.

•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.

•Do not tow a trailer during break-in. See Towing a Trailer on page 4-59for more information.
