Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 26).Notes on the technical data
i The technical data was determined in
accordance with EC Directives. All data
applies to the vehicle's standard equip-
ment. Therefore, the data may differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre.
You can find technical data on the Internet at:
http://www.mercedes-benz.com Genuine Mercedes-Benz parts
Mercedes-Ben ztests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benzis
unable to evaluate other parts. Mercedes-
Ben ztherefore accepts no responsibility for
the use of such parts in Mercedes-Ben zvehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement .The use of non- approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R
they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected. G
WARNING
Driving safety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Ben zrecommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at
a qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. 350

ting equipment installed at a qualified spe-
cialist workshop. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose.
Deviations with respect to aerial locations,
output and frequencies must be approved by
Mercedes-Benz.
There is no restriction for aerial positions in
the outer area of the vehicle for these wave- bands: trunked radio/Tetra, 70 cm wave-
band, GSM 900/AMPS, GSM 1800 and

Additives
!
Do not use additives in engine oil. This
could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid
.Ifanengine oil has a high viscosity,
this means tha titis thick; a low viscosity
means that it is thin.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
below shows you which SAE classifications
are to be used. The low-temperature proper-
ties of engine oils can be significantly
impaired during operation due to, for exam-
ple, ageing or soot and fuel accretion. It is
therefore strongly recommended to observe
regularo il changes using an approved engine
oil with the appropriate SA Eclassification. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
fro mt he air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre.
i There is usually a notice in the engine
compartmentt o remind you when the next
brake fluid change is due. Coolant
Important safety notes The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engine could otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Servic eProducts, MB
