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.
