200 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 
(page 34).
W
The yellow low windshield and 
headlamp* washer system fluid 
level warning lamp remains lit af-
ter starting the engine or lights 
up while driving.
The fluid level has dropped to about
1/3 of 
total reservoir capacity.
Add washer fluid (
page 179).
N
The yellow low engine oil level 
warning lamp remains lit after 
starting the engine or lights up 
while driving.
The engine oil level is too low.
Check the engine oil level 
(page 172) and add oil as required 
(page 175).
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.

Replacing bulbs
Replacing bulbs
Safe vehicle operation depends on proper 
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies are in good working order at all 
times.
Correct headlamp adjustment is extremely 
important. Have headlamps checked and 
readjusted at regular intervals and when a 
bulb has been replaced. See your autho-
rized Mercedes-Benz Center for headlamp 
adjustment (
page 226).
