2-20 Features and Controls If the PASS-Key® III+ key is lost or damaged, see your dealer/retailer or a locksmith to have a new key made. The SERVICE THEFT DETERRENT SYSTEM message displays on the Driver Information Center (DIC) when there is a problem with the theft-deterrent system. See DIC Warnings and Messages on page 3-50 for additional information. Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle. Starting and Operating Your Vehicle New Vehicle Break-In Notice: The vehicle does not need an elaborate break-in. But it will perform better in the long run if you follow these guidelines: • Avoid making hard stops for the first 200 miles (322 km) or so. During this time the 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 4-24 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. • If you have all-wheel drive, keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). • 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.
