General notes
Have your vehicle winterized at a qualified
specialist workshop, e.g. an authorized
Sprinter Dealer, at the onset of winter.
This service includes the following:
R oil change, if the engine oil currently used
does not have adequate low temperature
characteristics or if these are no longer
sufficient due to aging
R the antifreeze/anticorrosion
concentration in the coolant is checked.
R the addition of a concentrated cleaning
agent to the water in the windshield
washer/headlamp cleaning system
R battery check
R a tire change
Prior to the

onset of winter, ensure that snow
chains are available in the vehicle.
Do not cover the surface of the radiator or the
radiator grill, even in winter. Doing so could
cause the engine diagnostics to record false
or incorrect data. Recording of engine
diagnostic data is legally prescribed and must therefore be correct, clear and
comprehensible at all times.
