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: Ignition Positions With the ignition key in the ignition, the key can be turned to four different positions: • 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. • 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 the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is in all the way. If none of this works, then your vehicle needs service. A (OFF): This is the only position in which the ignition key can be inserted or removed. This position locks the ignition and transaxle. It is a theft-deterrent feature. 2-23
