distances

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 informationcan be obtained at aqualified specialist work-
