if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! If your vehicle is equipped with the tyre
pressure monitor, there are electronic
components in the wheels.
Fitting tools must not be used in the area
of the valve. Otherwise, the electronic com-
ponents could be damaged.
Always have the tyres replaced at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergency spare wheel/spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel. Cleaning the wheels
G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent. Wheel and tyre combinations
Please bear the following in mind
! For safety reasons, Mercedes-Ben zrec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benzs pecifically for your vehi-
cle.
These tyres have been specially adapted
for use with the contro lsystems, such as
ABS or ESP ®
, and are marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-BenzO riginal Extended
(tyres with run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damage resulting from the use of tyres,
wheels or accessories othe rthan those tes-
ted and approved.
Further information about tyres, wheels
and approved combinations can be
obtained from any Mercedes-Benz Service
Centre.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Ben zcannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. 310

You will find a table of tyre pressures on
the inside of your vehicle's fuel filler flap.
For further information on tyre pressure,
see (Y page 305).
i Notes on the vehicle equipmen t–always
fit the vehicle:
R with tyres of the same size on a given axle
(left/right)
R with the same type of tyres at a given
time (summer tyres, winter tyres,
MOExtended tyres)
i Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit
if you fit tyres that do not feature run-flat
properties, e.g. winter tyres. You can obtain
aT IREFIT kit from aMercedes-Benz Service
Centre, for example.

lowing tyre tables:

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
available at the time of publicatio nofthe
Owner's Manual. Country-specific differen-
ces are possible. Please note that your
vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. 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.
The use of non-approved parts could affect
your vehicle's operating safety. Therefore,
Mercedes-Ben zrecommends genuine
Mercedes-Benz parts and conversion parts
and accessories that have been approved for
your vehicle. H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
Always specify the vehicle identification num-
ber and engine number when ordering genu-
ine Mercedes-Benzp arts. You will find these
numbers on the vehicle identification plates
on your vehicle, for example ( Ypage 318). Vehicle electronics

mobile phones (RF transmitters)
Use the Technical Specification

implementation regulation
when retrofitting RF (radio frequency) trans-
mitters.
If your vehicle has fittings for two-way radio
equipmen t(e.g. taxis, hire cars or official vehi-
cles), use the power supply or aerial connec-
tions intended for use with the basic wiring.
Be sure to observe the manufacturer's addi-
tional instructions when installing the fittings.
! Have aftermarket radio frequency trans-
mitting equipment installed at a qualified
specialist workshop. Mercedes-Benzr ec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose.
The transmission output at the aerial base
must not exceed the maximum values below. Waveband Maximum trans-

Risk of injury
Incorrect retrofitting of RF transmitters can
lead to increased electromagnetic radiation in
the vehicle interior. Using an exterior aerial
takes into account current scientific discus-
