To program the new key, do the following: 1. Verify that the new key has PK3 stamped on it. 2. Insert the current driver's key in the ignition and start the engine. If the engine will not start, see your dealer for service. 3. After the engine has started, turn the key to OFF, and remove the key. 4. Insert the key to be programmed and turn it to RUN within 10 seconds of removing the previous key. 5. The SECURITY light will turn off once the key has been programmed. It may not be apparent that the SECURITY light went on due to how quickly the key is programmed. 6. Repeat Steps 1 through 4 if additional keys are to be programmed. 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. Your PASS-Key® III system, however, is not working properly and must be serviced by your dealer. Your vehicle is not protected by the PASS-Key® III system at this time. If you lose or damage a PASS-Key® III key, see your dealer to have a new key made. 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 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 4-38 for more information. 2-21
