Jump-starting
G
Risk of injury
There is a risk of acid burns when jump-starting a vehicle due to the gases which escape from
the battery. Do not lean over the battery while the engine is being jump-started. G
Risk of explosion
Gases escaping from the battery during jump-starting may cause minor explosions. Avoid cre-
ating sparks. Keep naked flames away from the battery, and do not smoke.
Comply with safety precautions when handling batteries. You will find these under "Battery" in
the index.
! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may dam-
age the catalytic converter 39
and create a risk of fire.
Do not use a rapid-charging device to start the engine.
Make sure the jump leads are not damaged.
Make sure the jump leads are not touching any other metal objects when they are connected
to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle
or from a second battery using jump leads.
Observe the following points:
X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
X Only jump-start the vehicle when the engine is cold and the catalyti cconverter system has
cooled down 40
.
X Do not start the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
X Only use jump leads that have a sufficient cross-section and insulated terminal clamps.
X Make sure that the jump leads cannot come into contact with parts, such as the pulley or
the fan. These parts move when the engine is started and while it is running.
X If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start.T his charges the empty battery a little.
i Jump leads and further information about jump-starting can be obtained from any

Important safety notes
Observe the legal requirement sfor the rele-
vant countries when towing and tow-starting. G
Risk of accident
If you tow the vehicle, you must use a rigid
towing bar if:
R the engine is not running.
R there is a brake system malfunction.
R there is a malfunction in the power supply
or the vehicle's electrical system. The power steering and the brake force boos-
ter do not work when the engine is not run-
ning. You will then need considerably more
force to steer and to brake and the brake
pedal travel will be longer. If necessary,
depress the brake pedal with maximum force.
Before towing away, make sure that the steer-
ing can be moved and is not locked.
If you tow or tow-start another vehicle, its
weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. Towing and tow-starting

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

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

Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.

(Y page 142).
Notes on 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 in mountainous terrain
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.
The consumption figures for vehicles up to
the EURO 4standard have been deter-
mined in accordance with EU Directive
80/1268/EEC while figures for vehicles
complying with the EURO 5standard or
higher have been determined in accord-
ance with Regulation (EC) No. 715/2007,
in each case based on the currently appli- cable version. Deviations fro
mthese values
may occur under normal operating condi-
tions.
! Do not use any fuel additives, as they can
cause malfunctions and engine damage. H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists 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. Engine oil
Please bear the following in mind The quality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Ben zapproves
engine oils which correspond to the current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Ben zrecommends that you have the oil
change carried out at a Mercedes-Benz
Service Centre. Mercedes-Benza pproval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the corresponding
designation, e.g. MB Approval 229.51.
The table shows which engines oil have been
approved for your vehicle.
