the
mtoa Mercedes-Benz Service Centre or
to as pecial collectio npoint for old batteries. G
Risk of inju
ry
Fo rs afety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. Thes ebatteries provide
increased impact protection to prevent vehi-
cle occupant sfrom suffering aci dburns
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 abattery.
Otherwise ,you coul dcause ashort circuit
and the battery's gas mixtur ecould ignite.
R mak esure that you do not create an elec-
trostatic charge, e.g. by wearing synthetic
clothing or as aresult of friction on fabrics.
Therefore, you should not pull or slide the
batter yover carpets or other synthetic
materials.
R neve rtouch the battery first. To discharge
ap ossible electrostatic charge, step out of
the vehicle first and touc hthe bodywork.
R do not wipe the battery usin gacloth. The
battery may explode as aresult of electro-
static charge or due to flying sparks.
! Switc hoff th eengine and remove the key
before disconnectin gthe termi nalclamps
from the battery .Onvehicles with KEY-
LE SS -GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluste rare off.
Otherwise, yo umay destroy electronic
components, such as the alternator.
i Remove the key if you park the vehicle
and do not require any electrical consum-
ers. The vehicle will then use very little
energy, thus conserving battery power.
Mercedes-Benz recommends that you do not
carr yout work on batteries yourself, e.g.
removing, charging or replacing. Always have this work performed at
aqualified specialist
workshop, e.g. aMercedes-Ben zService
Cent re. Installation location of the battery
Your vehicle is equippe dwithabatter yint he

bulkhea dunder the filter box on the right-
hand sid eofthe vehicle when viewed in the
direction of travel.
X Appl ythe parkin gbrake firml yand on vehi-
cles with automati ctransmission, shift the

X Turn the key to position 0(Ypage 135) in
the ignition lock and remove it, or, with
KEYLESS-GO, make sure that the ignition
