2005 MERCEDES-BENZ C WAGON maintenance

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.

System)
Information and operating center for
vehicle sound and communications
systems, including the radio and the
navigation system, as well as other
optional equipment (CD changer*,
telephone*, etc.).
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to
adjust settings.
Cruise control
Driving convenience system that
automatically maintains the vehicle
speed set by the driver.Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine
produced.
Engine oil viscosity
Measurement for the inner friction
(viscosity) of the oil at different temper-
atures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can
tolerate without becoming viscous, the
better the viscosity.
ESP
(E
lectronic S
tability P
rogram)
Improves vehicle handling and
directional stability.
ETD
(E
mergency T
ensioning D
evice)
Device which deploys in certain frontal
and rear collisions exceeding the
system's threshold to tighten the
seat belts.
->SRSFSS (Canada vehicles)
(F
lexible S
ervice S
ystem)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. FSS evaluates
engine temperature, oil level, vehicle
speed, engine speed, distance driven
and the time elapsed since your last
maintenance service, and calls for the
next maintenance service accordingly.
Gear range
Number of gears which are available to
the automatic transmission for shifting.
The automatic gear shifting process
can be adapted to specific operating
conditions using the gear selector
lever.
GPS
(G
lobal P
ositioning S
ystem)
Satellite-based system for relaying
geographic location information to and
from vehicles equipped with special
receivers. Employs CD digital maps for
navigation.

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.
