Driving when your engine is badly overheated can
cause some fluids which may have leaked into the
engine compartment to catch fire. You could be
seriously burned.Steam from an overheated engine can cause serious
burns and can occur just by opening the engine
hood. Stay away from the engine if you see or hear
steam coming from it.Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.

the engine for visible leakage (loss of oil).
It may be that there is water in the engine oil. Have the engine oil
checked.
5 The measuring system is malfunctioning.
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.
