206 Practical hintsWhat to do if …When the low engine oil level warning lamp
does not go out after starting the engine,
or comes on 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 lamp 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.Problem
Possible cause
Suggested solution
_
The red telescoping steering
column* warning lamp remains
lit after starting the engine.
The adjustable steering column is not locked
properly.

Lock the steering column

headlamp* washer system fluid
level warning lamp remains lit af-
ter starting the engine or lights
up while driving.

The yellow low engine oil level
warning lamp remains lit after
starting the engine or comes on
while driving.
The engine oil level has sunk to the minimum
level.

Check the engine oil level
(page 175) and add oil as required
(page 179).

If you must add engine oil frequently,
have the engine checked for possible
leaks.!The low engine oil level warning light
should not be ignored. Extended driv-
ing with the light illuminated could re-
sult in serious engine damage that is
not covered by the Mercedes-Benz
Limited Warranty.
