requirements.
X Unload heavy luggage.
i Only operate the tyre inflation compres-
sor using a12Vsocket (Y page 309), even
if the ignition is turned off.
An emergenc ycut-off ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine. TIREFIT kit
Usin gthe TIREFIT kit Yo

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 ver ylittle
energy, thus conserving battery power.
Mercedes-Benz recom mends that you do not
carry out work on batteries yourself, e.g.
removing or charging. Have this work per-
formed at aqualified specialist workshop, e.g.
aM ercedes-Benz Servic eCentre. Installation location of the battery
Your vehicle is equipped with abattery in the
vehicle interior. It is located under the front
seat on the right-hand side of the vehicle
when viewed in the direction of travel.
X Apply the electric parking brake and shift
the transmission to position P.
X Position the right-hand front seat as far for-
wards as possible.
X Switch off all electrical consumer s(e.g.

WARNING
There is arisk of acid burns when jump-starting avehicle due to the gases which escape from
the battery. Do not lean over the batter ywhile the engin eisbeing jump-started. G
WARNING
Gases escapin gfrom th ebattery 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 startin gattempts. Otherwise, non-combuste dfuel may dam-
age the catalytic converter 24
and create arisk of fire.
Do not use arapid-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 engin ecan be jump-started from another vehicle
or from asecond batter yusing jum pleads.
Observ ethe followin gpoints:
X The battery is not accessible in all vehicles. If the other vehicle' sbattery is not accessible,
jump-start the vehicle using asecond batter yorajump-star ting device.
X Only jump-start the vehicl ewhen th eengineisc old an dthe catalytic converter system has
cooled down 25
.
X Do no tstart the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batterie swithanominal voltage of 12 V.
X Only use jum pleads which have asufficient 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. Thes eparts move when the engine is started and while it is running.
X If the battery is fully discharged ,leave the batter ythat is being used to jump-star tconnected
for afew minutes befor eattempting to start. This charges the empty battery alittle.
i Jump leads and further information about jump-startin gcan be obtained from any
Mercedes-Ben zService Centre, for example.
X Make sure that the two vehicles do not touch.
X Secure the vehicle by applying the electric parking brake.
