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 The ignition switch is located on the instrument panel, to the right of the steering column. There are four different positions. Insert the key in the ignition and turn it to the right for each position. • 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 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. In order to shift out of PARK (P), ignition must be in the ON/RUN and the regular brake pedal must be applied. 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 all the way in. If none of this works, then your vehicle needs service. • Do not tow a trailer during break-in. See Towing a Trailer on page 4-29 for the trailer towing capabilities of your vehicle and more information. Following break-in, engine speed and load can be gradually increased. 9 (LOCK/OFF): This position locks the ignition, steering wheel and transmission. It is a theft-deterrent feature. This is the only position from which the key can be removed. 2-23
