degree of measuring accuracy.

Engine oil level is being measured. This
process can take approx. 1 minute when
stopped on a level surface with the engine
running and approx. 5 minutes while driv-
ing.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
> "Oil level at the minimum! Refill with 1 quart
of engine oil.":
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below. Add at least
0.5 US quart/0.5 liter. Otherwise the oil
level control may not display the new value
correctly.
If the oil level displayed is below minimum,
add engine oil immediately. Failure to do so
may lead to engine damage.
> "Engine oil level too high" * :
Have the vehicle checked immedi-
ately, otherwise engine damage may
result if too much oil has been added. <
> "Please observe recalculated service inter-
val for engine oil":
