Driving and Operating 8-17 Starting and Operating New Vehicle Break-In Follow these recommended guidelines during the first 2 414 km/1,500 miles of driving this vehicle. Parts have a break-in period and performance will be better in the long run. For the first 2 414 km/1,500 miles: . . Avoid downshifting to brake or slow the vehicle when the engine speed will exceed 4000 RPM. Do not let the engine labor. Never lug the engine in high gear at low speeds. With a manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period. Do not participate in track events, sport driving schools, or similar activities during this break-in period. Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km/1,500 miles. . . To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km/ 200 miles. New tires do not have maximum traction and may tend to slip. New brake linings also need a break-in period. Avoid making hard stops during the first 322 km/200 miles. This is recommended every time brake linings are replaced. . . Avoid full throttle starts and abrupt stops. Do not exceed 4,000 engine rpm. Avoid driving at any one constant speed, fast or slow. . . .
