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 your vehicle's
warranty and operating permit may be inva-
lidated. 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 aerial
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 aerial
fitted at a qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
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 qualified spe-
cialist workshop.
i Mercedes-Benz recommends the use of
an approved exterior aerial. This ensures
optimal reception quality for mobile tele- Technical data

Tyres and wheels
282 Tyres and wheels
Points to remember
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres which
have been approved specifically for your
vehicle by Mercedes-Benz. These tyres are
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-Benz
Service Centre.
i Vehicles with MOExtended run-flat sys-
tem are not equipped with the TIREFIT
kit* 35
.
Therefore, it is recommended that you
additionally equip your vehicle with the
TIREFIT kit* when fitting tyres that do not
feature run-flat properties, e.g. winter
tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz 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 adversely
affected. In addition, when driving with a
load, tyre dimensional variations could
cause the tyres to come into 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 178).

Risk of accident
Only have a trailer tow hitch retrofitted 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.
! If you have a trailer tow hitch retrofitted,
changes to the cooling system may be nec-
essary, depending on the vehicle type. If you have a trailer tow hitch retrofitted,
observe the anchorage points on the chas-
sis frame.

Notes on service products and capaci-
ties
Service products are:
R fuels (e.g. petrol, diesel)
R lubricants (e.g. engine oil, transmission oil)
R coolant
R brake fluid
R windscreen washer fluid
Mercedes-Benz recommends that you only
use those products which have been tested
and specially approved by Mercedes-Benz for
your vehicle and are listed in the Mercedes-
Benz Owner's Manual in the relevant chapter
since:
R parts and service products are matched
R damage caused by the use of non-approved
service products is not covered by the war-
ranty
You can recognise service products approved
by Mercedes-Benz by the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51) Other designations or recommendations that
relate to a level of quality or a specification in
accordance with an MB Approval have not
necessarily been approved by Mercedes-
Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
Risk of injury
When handling, storing and disposing of
any service products, please observe the
relevant regulations, as you could other-
wise endanger yourself and others.
Keep service products away from children.
To protect your health, do not allow service
products to come into contact with your
eyes or open wounds. See a doctor imme-
diately if any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuels
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Before refuelling, always turn off the
engine. G
Risk of injury
Do not allow fuel to come into contact with
skin or clothing.
Allowing fuels to come into direct contact
with your skin or inhaling fuel vapours is
damaging to your health.

adding the wrong fuel is not covered by the
warranty.
More information about refuelling and fuels
can be found on (Y page 168). Introduction to fuel consumption
The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R when towing a trailer
R in mountainous terrain The consumption figures have been deter-
mined according to EU Directive
RL 80
/1268 /EEC.
i Only for certain countries: the respective
current consumption and emission values
of your vehicle can be found in the COC
papers (EC-CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
! Do not use any special additives, as they
can cause malfunctions and engine dam-
age. Damage resulting from the use of such
additives is not covered by the Mercedes-
Benz warranty. H
Environmental note
CO 2(carbon dioxide) is the gas which sci-
entists believe to be principally responsible
for global warming (the greenhouse effect).
Your vehicle's CO 2emissions are directly
related to fuel consumption and therefore
depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly. Technical data

Do not use lubricant additives as they can
lead to increased wear and damage to
