OIL Display and measurement of
the engine oil level
Conditions for measuring the oil level
Caution!
Risk of engine damage.
Regularly check the oil level after refueling.
Do not allow the oil level to fall below the
minimum mark.
1. It is important to ensure that the vehicle is
horizontal for correct oil level measurement
to occur.
2. Engine is off.
3. Ignition on.
Oil return time
Before the oil level is measured, the engine oil
has to have flowed back into the oil pan. The time
taken for the engine oil to flow back depends on the
engine temperature and how long the engine has
been stopped.
This waiting time is counted down in the on-board
computer display when the ignition is switched on.
The oil level display segments start to “cycle”.
It is best to measure the engine oil level before
embarking on a journey (if the vehicle has not
been driven for an extended period) or with
the engine at operating temperature. Shorter
waiting times are achieved in this way.
Initiating oil level measurement
Switch ignition on (do not start the engine).
The engine-oil level measurement display
appears in the on-board computer.
Allow waiting time to elapse.
Once the measurement has been completed,
you can read off the engine oil level on the
segment display.
– If the segments are filled in up to the top line,
the oil level has reached the maximum mark.
Under no circumstances add engine oil.
