Risk of injury
Make sure that nobody can become trap-
ped as you close the bonnet.
X Lower the bonnet and let it fall from a
height of approximately 20 cm. The bonnet
engages into place. Engine oil
Depending on how it is driven, the vehicle
consumes a maximum of 0.8 l oil per 1,000
km. The oil consumption may be higher than
this when the vehicle is new or if you fre-
quently drive at high engine speeds. You can
only estimate the oil consumption after you
have driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
( Y page 258).
Checking the engine oil level To do so:
R
the vehicle should be parked on leve l
ground
R the engine should be switched off for at
least five minutes if the engine was at nor -
mal operating temperature
R the engine should be switched off for at
least 30 minutes if the engine was not at
operating temperature (i.e. if you only star-
ted the engine briefly ) Operation

has cooled down. The coolant temperature
gauge must display less than 70°C. Yo u

coolant.
Coolant consists of water and antifreeze/cor-
rosion inhibitor. Only check the coolant level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant leve

Genuine Mercedes-Benz parts
240 Introduction to technical dat
a
i The technical data was determined in
accordance with EU directives. All data
applies to the vehicle's standard equip-
ment. The data may therefore differ for
vehicles with optional equipment. You can
obtain further information from a
Mercedes-Benz Service Centre. Genuine Mercedes-Benz parts
Mercedes-Benz tests 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-Benz is
unable to evaluate other parts. Mercedes-
Benz therefore accepts no responsibility for
the use of such parts in Mercedes-Benz vehi-
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-Ben z
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 typ e
from that for which the vehicle's genera l
operating permit was granted
R other road users could be endangered
R the emission or noise levels are adversely
affected
The use of non-approved parts could affec t
your vehicle's operating safety. Mercedes -
Benz therefore recommends genuine Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle
. H
Environmental not
e
Daimler also supplies reconditione d
assemblies and parts which are of the same
quality as new parts and to which the same
warranty applies .
Genuine Mercedes-Benz parts and approved
conversion parts and accessories are availa-
ble from Mercedes-Benz Service Centres.
There, you can also receive advice about tech -
nical modifications and have the parts pro -
fessionally fitted.
Always quote the vehicle identification num-
ber and the engine number when ordering
genuine parts. You will find these numbers on
the vehicle data card in the Service Booklet
or on your vehicle's identification plates
( Y page 242). Technical data

s 241Vehicle electronics
Tampering with the engine electron-
ics
G
Risk of accident
Only have work on the engine electronics
and related components carried out at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The vehicle's roadworthiness could other-
wise be affected.
! Only have work done on the engine elec-
tronics and its associated parts, such as
control units, sensors and connector leads,
carried out at a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre. Otherwise, vehicle components
may wear more quickly and the vehicle may
lose its liability for material defects and its
operating permit. Retrofitting electrical and electronic
equipment
Electrical and electronic equipment can jeop-
ardise the operating safety of your vehicle. If
equipment of this kind is retrofitted, it must
be type-approved and bear the emark. The
e mark may be obtained from the equipment
manufacturer or an authorised testing centre.
! Damage or consequential damage arising
from fitting equipment not approved
by Mercedes-Benz is not covered by the
Mercedes-Benz warranty.
If you wish to install two-way radios in the
vehicle, you must obtain formal approval .
Mercedes-Benz approves the installation of
two-way radios if such equipment is installed
professionally and a low-reflection exterior
aerial is used.
The transmission output of the two-way radio
must not exceed the maximum transmission
outputs listed. G
Risk of accident
Two-way radios may interfere with the vehi-
cle electronics and thereby jeopardise the
operational safety of the vehicle and your
own safety if: R
they do not have an exterior aerial
R the exterior aerial is not a low-reflection
aerial
R the exterior aerial has been fitted incor-
rectly G
Risk of injury
Excessive electromagnetic radiation may
also cause damage to your health and the
health of others. Using an exterior aeria l
takes into account current scientific dis-
cussions relating to the possible health haz-
ards that may result from electromagnetic
fields .
For this reason, only have the exterior aeria l
fitted at a qualified specialist worksho p
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommend s
that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualifie d
specialist workshop.

an approved exterior aerial. This ensures

6 Tyres and wheels
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres which
have been approved by Mercedes-Benz
specifically for your vehicle. These tyres ar e
specially adapted for use with the control
systems, such as ABS or ESP ®
, and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Exten-
ded* (with run-flat characteristics)
If you use other tyres, Mercedes-Benz can-
not accept any responsibility for damage
which may occur. Information about tyres
can be obtained from any Mercedes-Ben z
Service Centre.
! If you fit tyres other than those tested and
recommended by Mercedes-Benz, charac-
teristics such as handling, noise levels and
fuel consumption, etc. may be adversel y
affected. In addition, when driving with a
load, dimensional variations and differen t
tyre deformation characteristics could
cause the tyres to make contact with the
bodywork and axle components. This could
result in damage to the tyres or the vehicle. i
Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre.
You will find a table of tyre pressures on the
inside of your vehicle's fuel filler flap . You
will find further information about tyre pres-
sures in the "Operation" section
( Y page 157). Technical data
