284 OperationEngine compartment
If engine is at normal operating
temperature, wait five minutes before
repeating check procedure.

If engine is not yet at normal operating
temperature, wait 30 minutes before
repeating check procedure.
If you see the message:
Engine oil level
Not when engine on!
Turn off the engine.

If the engine is at normal operating
temperature, wait five minutes before
checking oil.

If the engine is not yet at normal
operating temperature, you must wait
30 minutes before checking oil.If there is excess engine oil with the engine
at normal operating temperature, the
following message will appear:
Engine oil level
Reduce oil level
!

Have excess oil siphoned or drained
off. Contact an authorized
Mercedes-Benz Center.
More information on messages in the
display concerning engine oil can be found
in the “Practical hints” section
(
page 333). Adding engine oil!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
!Only use approved engine oils. For a
listing of approved engine oils, refer to
the Factory Approved Service Products
pamphlet in your vehicle literature port-
folio.
In addition, check the oil filler cap for
important information pertaining to the
engine oil needing to meet a specific
Mercedes-Benz specification (e.g. MB
229.5). If such information is printed
on the oil filler cap, only use an engine
oil from the list of approved engine oils
in the Factory Approved Service Prod-
ucts pamphlet that meets the specifi-
cation indicated on the oil filler cap.
Using engine oils of other specification
may cause the FSS to incorrectly deter-
mine the next service interval and will
result in engine damage not covered by
the Mercedes-Benz Limited Warranty.

285 Operation
Engine compartment
1Filler cap
Unscrew filler cap1 from filler neck.

Add engine oil as required. Be careful
not to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.

Screw filler cap1 back on filler neck.
More information on engine oil can be
found in the “Technical data” section
(
page 400) and (
page 403).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the transmission.Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
The coolant expansion tank is located on
the driver’s side of the engine compart-
ment.
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.

What to do if …
Display symbol
Display messages
Possible cause
Possible solution
_
Steering oil
Visit workshop!
The steering gear oil level is too low.
There is a danger of steering gear dam-
age.

Have the system checked by an au-
thorized Mercedes-Benz Center.
Entry position
Do not drive!
Seat, mirrors and steering wheel have not
yet moved to their preset driving posi-
tions.

Wait until the seat, mirrors and steer-
ing wheel have moved to their driving
positions.
The message disappears.
Ê
Trunk open!
This message will appear whenever the
trunk lid is open.

Close the trunk lid.
W
Washer fluid
Check level!
The fluid level has dropped to about
1/3
of total reservoir capacity.
Add washer fluid (
page 288).
Warning!
G
If the level of steering gear oil in reservoir is
too low, the steering power assistance could
fail. Much greater effort will then be needed
to turn the steering wheel.
Do not add steering oil without checking the
steering system.
Do not drive the vehicle. Have the system
checked at your authorized Mercedes-Benz
Center as soon as possible.

Engine oils
Engine oils are specifically tested for their
suitability in our engines. Therefore, use
only engine oils recommended by
Mercedes-Benz. Information on recom-
mended brands is available in the Factory
Approved Service Products Pamphlet, or at
your authorized Mercedes-Benz Center.Please follow FSS recommendations for
scheduled oil changes. Failure to do so
could result in engine damage not covered
by the Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil is used in the air condition-
ing system.Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the
system will occur.
Brake fluid
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Therefore, the brake fluid must be re-
placed every two years, preferably in the
spring.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
!Always check the oil filler cap
(page 285) for important information
pertaining to the engine oil needing to
meet a specific Mercedes-Benz specifi-
cation (e.g. MB 229.5). If such informa-
tion is printed on the oil filler cap, only
use an engine oil from the list of ap-
proved engine oils in the Factory Ap-
proved Service Products pamphlet that
meets the specification indicated on
the oil filler cap.
Using engine oils of other specification
may cause the FSS to incorrectly deter-
mine the next service interval and will
result in engine damage not covered by
the Mercedes-Benz Limited Warranty.

405 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%
anticorrosion / antifreeze [equivalent to
freeze protection to approximately - 22°F
(-30°C)]. If you use a solution that is more
than 55% anticorrosion / antifreeze [freeze
protection to approximately - 49°F
(-45°C)], the engine temperature will in-
crease due to the lower heat transfer capa-
bility of the solution. Therefore, do not use
more than this amount of
anticorrosion / antifreeze.
