Engine oil
General
Engine oil consumption depends on the driving
style and operating conditions.
Therefore check the engine oil level regularly
each time you fill up with fuel by taking a detailed
measurement.
Engine oil consumption may increase due to the
following, for example:
▷ Dynamic driving style.
▷ Running in the engine.
▷ Engine idling.
▷ Use of engine oil grades categorised as un‐
suitable.
Different Check Control messages are shown on
the Control Display, depending on the engine oil
level.
Safety notes
NOTE
Too little engine oil causes engine damage.
There is a risk of material damage. Top up with
engine oil immediately.
NOTE
Too much engine oil can damage the engine or
the catalytic converter. There is a risk of mate‐
rial damage. Do not add too much engine oil. If
there is too much engine oil, have the engine
oil level corrected by a Service Partner of the
manufacturer or another qualified Service Part‐
ner or a specialist workshop.
