2003 MERCEDES-BENZ S CLASS engine oil

375 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. You should have it replaced every
15 years or 150 000 miles (250 000 km),
whichever comes first.
Coolant system design and coolant used
stipulate the replacement interval. The
above replacement interval is only applica-
ble if MB 325.0 anticorrosion/antifreeze
solution or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products pam-
phlet) are used to renew the coolant con-
centration 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.
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).
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.

382 Technical termsCOMAND
(C
ockpit M
anagement and D
ata Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and navi-
gation, as well as for 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 ad-
just settings.
Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.


If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.
Engine number
The number set by the manufacturer
and stamped on the cylinder block to
uniquely identify each engine pro-
duced.Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP
(E
lectronic S
tability P
rogram)
Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency T
ensioning D
evice)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.
