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: Ignition Positions The ignition switch has 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 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. To shift out of P (Park), turn the ignition to ON/RUN and apply the regular brake pedal. Notice: Using a tool to force the key to turn in the ignition could cause damage to the switch or break the key. Use the correct key, make sure it is all the way in, and turn it only with your hand. If the key cannot be turned by hand, see your dealer/retailer. (A) LOCK/OFF: This position locks the ignition. It also locks the transmission on automatic transmission vehicles. It locks the steering wheel on manual transmission vehicles. The key can on be removed in LOCK/OFF. • Do not tow a trailer during break-in. See Towing a Trailer on page 4-47 for the trailer towing capabilities of the vehicle and more information. Following break-in, engine speed and load can be gradually increased. 2-18
