8-2 Driving and Operating • Between the first 600 miles (1 000 km) and 3,000 miles (5 000 km), heavy acceleration in lower gears can be used. Vehicle speeds above 68 mph (110 km/h) should be limited to five minutes per use. 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 • 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 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. The ignition switch has four different positions. 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. To shift out of P (Park), turn the ignition to ON/RUN and apply the brake pedal. • Do not tow a trailer during break-in. See Towing a Trailer on page 9-85 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. • During the first 600 miles (1 000 km), avoid using more than moderate acceleration in lower gears and avoid vehicle speeds above 68 mph (110 km/h).
