Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.

value indicates the current oil level in liters
above Minimum.
After starting the engine, the last determined
value is displayed.
The oil level must be between the two marks.
Exact measurement
The oil level is measured continuously while
driving or when stopped with the engine run-
ning.
The determination of a new value can take
30 minutes or longer.
If only dashes are shown in the display, it
was not possible to determine a new
value. This can, for example, be the case when
driving short distances or with a sporty driving
style.<
Fast measurement
In addition to the continuous measurement, you
can also quickly determine the current oil level,
e.g. after adding engine oil, however with a low
measuring accuracy.
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button in the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button in the turn signal lever
for at least 2 seconds.
The oil level is determined. A clock symbol
is displayed during the measurement.
5.After approx. 1 minute the current oil level is
displayed.
If not all measuring conditions are met,
e.g. with the engine cold, "-.-" is dis-
played. The requested measurement is carried
out as soon as possible.<
Possible displays
1Oil level OK
2Oil level at minimum:
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below
3Oil level too high
Have the vehicle checked immedi-
ately, otherwise engine damage may
result if too much oil has been added.<
4Oil level at maximum
5Quick measurement running: oil level is
being determined
6No value can be determined at this time
Adding engine oil
Do not add oil until a value slightly above the
Minimum of 0.0 quarts/liters is displayed by the
oil level measurement. In this area a message is
also shown on the Control Display.
Add oil within the next 125 miles/200 km,
otherwise the engine could be damaged.
Add a maximum of 1 US quart/1 liter of oil, oth-
erwise the engine may be damaged by adding
too much oil.
