to operate the vehicle. Otherwise, the engine will overheat due to
an inoperative water pump which may result in damage to the
engine. Do not continue to drive the vehicle with this message
displayed. Doing so could result in serious engine damage that is
not covered by the Mercedes-Benz Limited Warranty.
2 The cooling fan for the coolant is faulty. Observe the coolant temperature gauge. See page 137
During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to 120
°C.
The engine should not be operated with the coolant
temperature above 120
°C. Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.

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.

1 The engine oil level must be checked immediately. See Engine oil
level indicator on page 141.
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
indicator on page 141.
4 The engine oil level has dropped to a critical level. Check the engine oil level immediately. See Engine oil level
indicator on page 141 and check 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.
