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 1 000 miles (1 500 km) at moderate 
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle 
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended 
to brake the vehicle by manually shifting to a lower gear. 
We recommend that you select positions “3”, “2” or “1” 
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually 
increased to the permissible maximum.Maintenance
Approximately 30 days or 2000 miles (2000 km) prior 
to the next recommended service, the remaining 
distance or days are displayed in the multifunction 
indicator. See Flexible service system (FSS) on page 147.
We strongly recommend that you have your vehicle 
serviced by your authorized Mercedes-Benz Center, in 
accordance with the Service Booklet at the times called 
for by the FSS.
Failure to have the vehicle maintained in accordance 
with the Service Booklet at the designated times/
mileage may result in vehicle damage not covered by 
the Mercedes-Benz Limited Warranty.
