Starting and Operating Your Vehicle New Vehicle Break-In Notice: Your vehicle doesn't need an eiaborate "break-in." But it will perform better in the long run if you follow these guidelines: e Ignition Positions With the key in the ignition, you can turn the switch to four positions. The ignition switch is located on the instrument panel, to the right of the steering column. Don't drive at any one speed - fast or . slow - - for the first 500 miles (805 km). Don't make full-throttle starts. Avoid making hard stops for the first 200 miles (322 km) or so. During this time your new brake linings aren't 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. Don't tow a trailer during break-in. See "Towing a Trailer" in the index for more information. e e OFF: This is the only position from which you can remove the key. Removing the key locks your ignition and automatic transaxle. Notice: If your key seems stuck in OFF and you can't turn it, be sure you are using the correct key; if so, is it all the way in? Turn the key only with your hand. Using a tool to forceit could break the key or the ignition switch.If none of this works, then your vehicle needs service. 2-17
