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
(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 184).
N
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.

281 Technical data
Fuels, coolants, lubricants etc.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:
Corrosion protection
Freeze protection
Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -22°F (-30°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil over-pro-
tection. Refer to Service Booklet for
replacement interval.
Coolant system design and coolant used
stipulate the replacement interval. The re-
placement interval published in the Ser-
vice Booklet is only applicable if MB 325.0
anticorrosion/antifreeze solution or other
Mercedes-Benz approved products of
equal specification (see Factory Approved
Service Products pamphlet) are used to re-
new the coolant concentration or bring it
back up to the proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. -22°F [-30°C]). If you
use a solution that is more than 55% anti-
corrosion/antifreeze (freeze protection to
approx. -49°F [-45°C]), the engine temper-
ature will increase due to the lower heat transfer capability of the solution. There-
fore, do not use more than this amount of
anticorrosion/antifreeze.
If the coolant level is low, water and MB
Anticorrosion /Antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure the mixture is in accor-
dance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult your authorized Mercedes-Benz
Center.
