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.
This chapter describes all standard, country-spe‐
cific and optional equipment available for the
model series. It may therefore describe equip‐
ment and functions which are not installed in
your vehicle, for example on account of the spe‐
cial equipment selected or the country specifica‐
tion. This also applies to safety-relevant func‐
tions and systems. Please comply with the
relevant laws and regulations when using the
corresponding functions and systems.
Electronic oil measurement
General
General
Electronic oil measurement uses two measuring
procedures:
Engine oil consumption depends on the driving
style and operating conditions.
▷ Monitoring.
Therefore check the engine oil level regularly
each time you fill up with fuel by taking a detailed
measurement.
▷ Detailed measurement.
When frequently making short journeys or using
a sporty driving style, for example fast cornering,
perform a detailed measurement at regular inter‐
vals.
Engine oil consumption may increase due to the
following, for example:
▷ Dynamic driving style.
▷ While running in the engine.
▷ Engine idling.
Monitoring
Principle
▷ Use of engine oil grades rated as unsuitable.
The engine oil level is monitored electronically
during the journey and can be shown on the
Control Display.
Different Check Control messages are shown on
the Control Display, depending on the engine oil
level.
If the engine oil level is outside its permissible
operating range, a Check Control message is
shown.
Safety notes
Operating requirements
A current measurement is available after approxi‐
mately 30 minutes of normal driving.
NOTE
Too little engine oil causes engine damage.
There is a risk of material damage. Top up with
engine oil immediately.
