Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking engine oil level
Your vehicle is equipped with an electronic oil
level check.
The condition for the most accurate indication
of the oil level possible is measurement with the
engine at operating temperature, i.e. following
an uninterrupted drive of at least 6 miles/10 km.
You can display the oil level on the Control Dis-
play while driving or when stopped on a level
surface with the engine running.

Possible messages
>"Engine oil level O.K."
>"No measurement available: Updating
engine oil level measurement...":
The engine oil level is measured. This pro-
cess 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/liter of
engine oil at the next opportunity, refer also
to Adding engine oil below. Add at least
0.5 US quart/liter of oil; otherwise, the oil
level check cannot reliably display the new
oil level.
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":
Do not add engine oil. Before continuing to
drive, note the recalculated remaining mile-
age until the next oil change service, refer to
Service requirements on page79. Have the
system checked as soon as possible.
