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 key in the ignition switch, you can turn to four different positions. • Keep your speed at 55 mph (88 km/h) or less for the first 500 miles (805 km). • 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. {CAUTION: On manual transmission vehicles, turning the key to LOCK will lock the steering column and result in a loss of ability to steer the vehicle. This could cause a collision. If you need to turn the engine off while the vehicle is moving, turn the key only to ACC. Do not push the key in while the vehicle is moving. • Do not tow a trailer during break-in. See Towing a Trailer on page 4-57 for more information. 2-18
