Radiator
Vehicles with a diesel engine: do not cover
the radiator. Do not use thermal mats, insect
protection covers or anything similar. Doing
so can cause the Onboard Diagnostics Sys-
tem to display inaccurate values. Some of
these values are legally required and must
always be correct.
Engine oil
General notes
Depending on your driving style, the vehicle
consumes up to 0.8 litres of oil per
1,000 km. The oil consumption may be higher
than this when the vehicle is new or if you
frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may
be installed at a different location.
When checking the oil level:
R
park the vehicle on a level surface.
R
the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R
if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait about 30 minutes
before carrying out the measurement.
