yellowblue To program the new key: 1. Insert the current driver's key (black in color) in the ignition and start the engine. If the engine will not start, see your dealer for service. 2. After the engine has started, turn the key to OFF, and remove the key. 3. Insert the key to be programmed and turn it to RUN within 10 seconds of removing the previous key. 4. The SECURITY telltale 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. 5. 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 or a locksmith who can service PASS-Key III to have a new key made. New Vehicle "Break-In" NOTICE: Your vehicle doesn't need an elaborate "break-in." But it will perform better in the long run if you follow these guidelines: D Don't drive at any one speed -- fast or slow -- for the first 500 miles (805 km). Don't make full-throttle starts. D Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren't 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. D Don't tow a trailer during break-in. See "Towing a Trailer" in the Index for more information. 2-19
