You can obtain information about battery
chargers which allow the batter ytobe
charged while still installed from aqualified
specialist workshop ,e.g. aM ercedes-Benz
Ser vice Centre. G
WARNING
There is arisk of acid burns during the charg-
ing process due to the gases which escape
from the battery. Do not lean over the battery
during the chargin gprocess. G
WARNING
Battery aci discaustic. Avoid contact with the
skin, eyes or clothing.
! Only charge the installed batter ywith a
batter ycharger whic hhas been tested and
approved by Mercedes -Benz .These battery
chargers allow the battery to be charged
while still installed. !
Only use battery chargers with amaxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartmen t(Ypage 348).

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.
