Preparing the vehicle
Your vehicle may be equipped with:
R a TIREFIT kit
R an emergency spare wheel
R MOExtended tyres (tyres with run-flat char-
acteristics) (Y page 324)
i Vehicle preparation is 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.

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 13
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 14
.
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.
X Make sure that the two vehicles do not touch.
X Apply the parking brake firmly.
X Manual transmission: engage neutral.
X Automatic transmission: move the selector lever toP.
X Switch off all electrical consumers (e.g. radio, blower, etc.).
X Open the bonnet (Y page 301).

missible gross vehicle weigh tofyour vehicle. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
It is better to have the vehicle transported
than to have it towed.

Important safety notes
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nents on the circuit and their functions stop
operating. G
WARNING
Only use fuses that have been approved for
Mercedes-Ben zvehicles and which have the
correct fuse rating for the systems con-
cerned. Do not attempt to repair or bridge
faulty fuses. Otherwise, a circuit overload
could cause a fire. Have the cause traced and
rectified at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Blown fuses must be replaced with fuses of
the same rating, which you can recognise by
the colour and value. The fuse ratings are lis-
ted in the fuse allocation chart .AMercedes-
BenzS ervice Centre will be happy to advise
you.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre.
! Only use fuses that have been approved
for Mercedes-Benzv ehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged. Electrical fuses
