"Oil"
Display and measurement of the engine
oil level
/!\
Caution!
Risk of engine damage.
I>
Regularly check the oil level each time the car
is refuelled.
I>
Do not allow the oil level to fall below the
minimum mark.
Conditions for measuring the oil level
1. Vehicle is level.
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".

Controls, Instruments
It is best to measure the engine oil level with the
engine at operating temperature. Correct meas-
urements and short waiting times are achieved
in this way.
Initiating oil level measurement
I>
Switch ignition on (do not start the engine).
The engine-oil level measurement display
appears in the on-board computer.
I>
Allow waiting time to elapse.
Once the measurement has been completed,
you can read off the engine oil level on the seg-
ment display.
If the oil level has fallen below the min. mark,
the segment below the min. mark flashes.
The difference between the min. and max.
marks on the segment display is approx. 1.25
litres.
One segment of the display corresponds to a
quantity of approx. 0.2 litre.
I>
Add engine oil if necessary.
Refer to the chapter "Engine oil level"
.
Before adding oil, switch ignition off.
Never add more engine oil than required to
reach the max. mark.
Oil level measurement during refuelling
The oil level is automatically measured during
refuelling. If the oil level is too low, "Check oil
level" appears in the on-board computer display.
However, this measurement is performed only if
the following preconditions are met:
Engine is at operating temperature, ignition is
off, refuelling is completed within 15 minutes.
Failure
A failure of the oil level display is indicated by a
warning message in the on-board computer.
