Operation The first 1000 miles (1500 km) The first 1000 miles (1500 km) In the "Operation" section you will find detailed information on operating, maintaining and caring for your vehicle. The more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on. Drive your vehicle during the first 1000 miles (1500 km) at varying but moderate vehicle and engine speeds. During this period, avoid heavy loads (full throttle driving) and excessive engine speeds (no more than 2/3 of maximum rpm in each gear). Avoid accelerating by kick-down. Do not attempt to slow the vehicle down by shifting to a lower gear using the gear selector lever. Select positions 3, 2 or 1 only when driving at moderate speeds (for hill driving). After 1000 miles (1500 km) you may gradually increase vehicle and engine speeds to the permissible maximum. All of the above instructions, as may apply to your vehicle type, also apply when the first 1000 miles (1500 km) after the engine, the transfer case, the front differential or the rear differential has been replaced. i Always obey applicable speed limits. 192
