mal operation of the vehicle. Servic ework will
need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further information can be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Fuel/water separator
