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, contact your dealer to have a new key made. In an emergency, contact Cadillac Roadside Assistance. See Roadside Service 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: • 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 4-39 for more information. 2-25
