379 Technical data
Fuels, coolants, lubricants, etc.
Coolants
The engine coolant is a mixture of water
and anticorrosion/antifreeze, which
provides:

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
corrosion protection.
If the antifreeze mixture is effective
to -22°F (-30°C), the boiling point of the
coolant in the pressurized cooling system
is reached at approx. 266°F (130°C).The coolant solution must be used
year-round to provide the necessary corro-
sion protection and increase boil-over
protection. Refer to Maintenance Booklet
for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance 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 renew 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 approx. - 22°F
(-30°C)]. If you use a solution that is more than 55%
anticorrosion/antifreeze [freeze
protection to approx. - 49°F (-45°C)], the
engine temperature will increase due to
the lower heat transfer capability of the
solution. Therefore, do not use more than
this amount of anticorrosion/antifreeze.
If the coolant level is low, water and
MB 325.0 anticorrosion/antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance 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,
consult an authorized Mercedes-Benz
Center.

380 Technical dataFuels, coolants, lubricants, etc.Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle engines
necessitates that anticorrosion/antifreeze
coolant used in such engines be specifi-
cally formulated to protect the aluminum
parts.Failure to use such anticorrosion/anti-
freeze coolant will result in a significantly
shortened service life.
Therefore, the following product is strongly
recommended for use in your vehicle:
Mercedes-Benz 325.0
Anticorrosion/Antifreeze Agent.Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked. The coolant is also
regularly checked each time you bring your
vehicle to an authorized Mercedes-Benz
Center for service.

381 Technical data
Fuels, coolants, lubricants, etc.
Windshield washer and headlamp cleaning system*
Both the windshield washer and headlamp
cleaning system* are supplied from the
windshield washer fluid reservoir.
The washer fluid reservoir has a capacity of
approx.:

3.2 US qt (3.0 l) in vehicles without
headlamp cleaning system*


6.4 US qt (6.0 l) in vehicles with
headlamp cleaning system*

Refill the reservoir with MB Windshield
Washer Concentrate and water
(or concentrate and commercially
available premixed windshield washer
solvent/antifreeze, depending on
ambient temperatures).Washer fluid mixing ratio
For temperatures above freezing point, use
MB Windshield Washer Concentrate “S”
and water:


1 part “S” to 100 parts water
(1.34floz [40ml]“S” to 1gallon [4.0l]
water)
For temperatures below freezing point, use
MB Windshield Washer Concentrate “S”
and commercially available premixed
windshield washer solvent/antifreeze:


1part“S” to 100parts solvent
(1.34floz [40ml]“S” to 1gallon [4.0l]
solvent)
Warning!
G
Washer solvent/antifreeze is highly flamma-
ble. Do not spill washer solvent/antifreeze
on hot engine parts, because it may ignite
and burn. You could be seriously burned.

387 Technical terms
Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision,
including the tachometer, speedo-
meter, engine temperature display and
fuel gauge.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the
vehicle and should not be used for
normal acceleration needs.
Lock button
Button on the door which indicates
whether the door is locked or
unlocked. Pushing the lock button
down on an individual door from inside
will lock that door.Maintenance System (U.S. vehicles)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. The Maintenance
System in your vehicle tracks distance
driven and the time elapsed since your
last maintenance service, and calls for
the next maintenance service accord-
ingly.
Memory function*
Used to store three individual seat,
steering wheel and mirror positions for
each SmartKey.
MON
(M
otor O
ctane N
umber)
The Motor Octane Number for gasoline
as determined by a standardized
method. It is an indication of a
gasoline's ability to resist undesired
detonation (knocking). The average of
both the MON (Motor Octane Number)
and ->RON (Research Octane Number)
is posted at the pump, also known as
ANTI-KNOCK INDEX.Multifunction display
Display field in the instrument cluster
used to present information provided
by the control system.
Multifunction steering wheel
Steering wheel with buttons for
operating the control system.
Overspeed range
Engine speeds within the red marking
of the tachometer dial. Avoid this
engine speed range, as it may result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
Poly-V-belt drive
Drives engine-components (alternator,
AC compressor, etc.) from the engine.
