of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

level indicator on page 117.
2 There is no oil in the engine. There is a danger of engine damage.3 There is a risk of damaging the engine or catalytic converter. The
engine oil level must be checked immediately. See Engine oil level
i n d i c a t o r o n p a g e 117 .
4 The engine oil level has dropped to a critical level.
Check the engine oil level immediately. See Engine oil level
indicator on page 117 and check the engine for visible leakage (loss
of oil).
5 The measuring system is malfunctioning.
6 It may be that there is water in the engine oil. Have the engine oil
che cked.
When the “ENGINE OIL LEVEL – CHECK LEVEL”
message appears while the engine is running and at
operating temperature, the engine oil level has dropped
to approximately the minimum mark on the dipstick.
When this occurs, the warning will first come on
intermittently and then stay on if the oil level drops
further.
If no oil leaks are noted, continue to drive to the nearest
service station where the engine oil should be topped to
the “full” mark on the dipstick with an approved oil.
The engine oil level warnings should not be ignored.
Extended driving with the symbol displayed could
result in serious engine damage that is not covered by
the Mercedes-Benz Limited Warranty.
