Important notes G
WARNING
Observe the legal requirements of the country
in which you are currently driving regarding
operating mobile communications equipment
in av ehicle.
If it is permitted by law to operate communi-
cations equipment while the vehicle is in
motion ,you must only do so if the traffic sit-
uation permits. Otherwise, you could be dis-
tracted from the traffic conditions, cause an
accident and injure yourself and others.
Two-way radios and fax equipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronics and thereby
jeopardise the operating safety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
WARNING
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
into account current scientific discussions
relating to the possible health risk posed by
electromagnetic fields. Features

The floormats must be correctly secured at all
times using retainer sand press-studs.
Before you drive off ,chec kthe floormats and
secure if necessary. Afloormat which is not

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 electrica lcon-
sumers .The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Ben zrecommends that you do not
carry out work on batteries yourself, e.g.
removin gorcharging. Have this work per-
formed at aqualified specialist workshop, e.g.
aM ercedes-Benz Service Centre. Installation location of the battery
Your vehicle is equipped with abatter yint he
engin ecompartment .Itislocated on the front
bulkhead under the filter box on the right-
hand side of the vehicle when viewed in the
direction of travel.
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(Y page 147) 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 147). All indicator lamps in the
instrument cluster must be off.
X Open the bonnet (Y page 281). X

! Alwaysd isconnect the battery in
the order described below. Never swap the
terminal clamps. You may otherwise dam-
age the vehicle electronics.
In vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehicle
is secured against rolling away. You can
then no longer move the vehicle. :

place.
X Remove the battery.
X To fit: follow the steps described in "To
remove" in reverse order. Reconnecting the battery

X Connect the positive terminal clamp and
secure the cover.
X Connect the negative terminal clamp.
X Put the filter box back in place, then clip in
and close the retaining clamps.
X Close the bonnet.
i If the power supply has been interrupted,
e.g. if the battery has been reconnected,
you must carry out the following tasks:
R set the clock (Y page 226).
R reset the function for automatically fold-
ing the exterior mirrors in/out by folding
the mirrors out once (Y page 110).Charging the battery
G
WARNING
Only charge the battery in awell-ventilated
area. As the battery is being charged, gases
can escape and generate minor explosions.
This could injure you and other persons or
cause damage to the paintwork or acid cor-
rosion on the vehicle.
You can obtain information about battery
chargers which allow the battery to be charged while still installed from
aqualified
specialist workshop, e.g. aMercedes-Benz
Service 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 acid is caustic. Avoid contact with the
skin ,eyes or clothing.
! Only charge the installed batter ywith a
batter ycharger which has 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 compartment( Ypage 309).
X Open the bonnet (Y page 281).
X Connect the battery charger to the positive
terminal and earth point in the same order
as when connecting the donor battery in
the jump-starting procedure
(Y page 309).
X Read the battery charger's operating
instructions before charging the battery. 308

Jump-starting
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 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 startinga ttempts. Otherwise, non-combusted fuel may dam-
age the catalytic converter 22
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 objectsw hen they are connected
to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle
or from asecond 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 asecond battery or ajump-starting device.
X Only jump-start th evehicl ewhen th eengineisc olda nd th ecatalyti cconverter system has
cooled down 23
.
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 anominal voltage of 12 V.
X Only use jump leads 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. 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 afew minutes before attempting to start.T his charges the empty batteryalittle.
i Jump leads and further information about jump-starting can be obtained from any
Mercedes-Ben zService 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.).
