0 Battery
Notes on the battery
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for a
lengthy period.
To prevent damage from corrosion, only
replace the battery with one that has a central
ventilation cover.
Consult a Mercedes-Benz Service Centre if
you wish to leave your vehicle parked up for
a long period of time. G
Risk of injury
Comply with safety precautions and take
protective measures when handling batter-
ies. Risk of explosion
Fire, naked flames and
smoking are prohibited
when handling the bat-
tery. Avoid creating
sparks. Battery acid is caustic.
Avoid contact with the
skin, eyes or clothing
.
Wear suitable protective
clothing, in particular
gloves, an apron and a
face mask.

Manual. H
Environmental not
e
Do not dispose of batteries with the house-
hold rubbish. Dispose of defective batteries
in an environmentally responsible manner.
Take them to a Mercedes-Benz Service Centre or a special collection point for ol
d
batteries. G
Risk of injury
Mercedes-Benz recommends that, for
safety reasons, you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz. These bat-
teries provide increased impact protectio n
to prevent vehicle occupants from suffering
acid burns should the battery be damage d
in the event of an accident .
To prevent acid burns, observe the follow-
ing safety notes when handling batteries:
R Do not lean over batteries .
R Do not place any metal objects on a bat-
tery. You could otherwise cause a short
circuit and the battery's highly flammabl e
gas mixture could ignite.
R Make sure that you do not create elec-
trostatic charge, e.g. by wearing syn-
thetic clothing or as a result of friction on
fabrics. You should not therefore pull or
slide the battery over carpets or other
synthetic materials.

R there is a brake system malfunctio n
R the voltage supply or the vehicle's elec-
trical system is damage d
There is no power assistance for the steer-
ing when the engine is not running.
It is better to have the vehicle transported
than to have it towed.
When towing, observe the legal requirement s
in all countries concerned.
! When towing, pull away slowly and with-
out jerking. If the tractive power is too high,
the vehicles could be damaged. Do not use
the towing eye for recovery.
! You may tow the vehicle for a maximum
of 50 km. A towing speed of 50 km/h must
not be exceeded.
With towing distances over 50 km, the
entire vehicle needs to be lifted up and
transported. !
Only secure the tow cable or towing bar
to the towing eyes. You may otherwise
damage the vehicle.
R Vehicles with an automatic transmission*
must not be tow-started.
R If the engine does not start, try jump-start-
ing it (Y page 233).
R If it is not possible to jump-start the vehicle ,
have it towed to the nearest qualified spe-
cialist workshop, e.g. a Mercedes-Ben z
Service Centre.
R If the vehicle has suffered transmission
damage, it must only be towed with the rear
axle raised.
R The selector lever must be in position Non
vehicles with automatic transmission*.
R If you are towing the vehicle over a consid-
erable distance, this may only be done with
the rear axle raised.
R The ignition must be switched off if you are
towing the vehicle with the front/rear axle
raised. Intervention by ESP ®
could other-
wise damage the brake system.
R Before towing the vehicle, make sure that
the battery is connected and charged. Oth-

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

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.
