Check Regularly and Before a Long Trip
See page 150
The First 1000 Miles (1500 km)
The more cautiously you treat your vehicle during the break-in period, the more satisfied you will be with its performance later on.
Therefore, drive your vehicle during the first 1500 km (1000 miles) at moderate vehicle and engine-speeds.
During this period, avoid heavy loads (full throttle driving) and high RPM (no more than 2/3 of maximum permissible speed in each
gear as indicated on the speedometer).
Downshift at proper engine speed!
On vehicles with automatic transmission avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually
shifting to a lower gear. We recommend to select positions "4" (for model 300 SL), "3" or "2" only at moderate speeds (for hill
driving).
After 1500 km (1000 miles) speeds may be gradually increased to the permissible maximum.
