Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R a spare wheel
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 345)
i Vehicle preparatio nis not necessary on
vehicles with 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. A TIREFIT kit
can be obtained from a Mercedes-Benz
Service Centre. X

tally responsible manner.
Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to a qualified spe-
cialist workshop, e.g. a
Mercedes-Benz Service
Centre, or to a special col-
lection point for old batter-
ies.
G
WARNING
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for yourv ehicle by
Mercedes-Benz .These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
R do not lean over the battery.
R do not place any metal objects on a battery.
Otherwise, you could cause a short circuit
and the battery's gas mixture could ignite.
R make sure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials.
R never touch the battery first. To discharge
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
R do not wipe the battery using a cloth. The
battery may explode as a result of electro-
static charge or due to flying sparks.
! Switch off the engine and remove the key
before disconnecting the terminal clamps
from the battery. On vehicles with KEY-
LESS-GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrumentc luster are off.You may otherwise destroy electronic compo-
nents, such as the alternator.
i When you park the vehicle, remove the
key if you do not require any electrical con-
sumers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carry out work on batteries yourself, e.g.
removing or charging. Have this work per-
formed at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre. Installation location of the battery
Your vehicle is equipped with a battery in the
engine compartment. It is fitted in front of the
front bulkhead on the right-hand side of the
vehicle when viewed in the direction of travel.
AMG vehicles: the battery is in the boot/
luggage compartment in the spare wheel well
on the right-hand side under the boot/lug-
gage compartment floor.
X Apply the parking brake firmly and, on vehi-
cles with automatic transmission, shift the
transmission to position P.
X Switch off all electrical consumers (e.g.
radio, blower, etc.).
X Turn the key to position 0(Ypage 153) in
the ignition lock and remove it, or, on vehi-
cles with KEYLESS-GO, make sure that the
ignition has been switched off
(Y page 153). All indicator lamps in the
instrument cluster must be off.

Jump-starting
G
WARNING
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
WARNING
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 18
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 19
.
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 which 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
Mercedes-Benz Service Centre, for example.

Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 28).Important safety notes
G
WARNING
Tyres, wheels or accessories which have not
been approved by Mercedes-Ben zfor your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident .Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre. Operation
Notes on driving
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed immediately. Stop the vehicle as soon as possible to chec
kthe
wheels and tyres for damage. Hidden tyre
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tyres
examined at a qualified specialist work-
shop, e.g. a Mercedes-Ben zService
Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Notes on regularly inspecting wheels
and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 359). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly check the pressure of all the tyres
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressure as necessary
