New Vehicle "Break-In" Ignition Positions Use your ignition key to start your vehicle. The ignition key lets you turn the ignition switch to five different positions. NOTICE: Your modern vehicle doesn't need an elaborate "break-in." But it will perform better in the long run if you followthese guidelines: 0 Keep your speed at 55 mph (88 k m h ) or less for thefirst 500 miles (805 km). 0 Don't drive at any one speed fast or 500 slow for the first miles (805 km). Don't make full-throttle starts. e Avoid making hard stops for the first 200 miles (322 km) or so. During thistime your new brake linings aren't yet broken in. Hard stops with new linings can mean premature wear and earlier replacement. Follow this breaking-inguideline every time you get new brake linings. 0 Don't tow a trailer during break-in.
