Check Regularly and Before a Long Trip
See Index
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).
Avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually shifting to a lower gear.
We recommend to select positions "3" or "2"only at moderate speeds (for hill driving).
After 1000 miles (1500 km) speeds may be gradually increased to the permissible maximum
Maintenance
We strongly recommend that you have your vehicle serviced by your authorized Mercedes-Benz dealer, in
accordance with the Maintenance Booklet.
Radio Transmitters
Warning!
Never operate radio transmitters equipped with a built-in or attached antenna (i.e. without the telephone
connected to an external antenna) from inside the vehicle while the engine is running. Doing so could lead
to a malfunction of the vehicle's electronic system, possibly resulting in an accident and personal injury.
Radio transmitters, such as a portable telephone or a citizens band unit, should only be used inside the vehicle
if they are connected to an antenna that is installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions regarding use of an external antenna.
