G Risk of injury
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event
of an accident.
To prevent acid burns, observe the following
safety notes when handling batteries:
do not lean over the battery.
R
do not place any metal objects on a battery.

Otherwise, you could cause a short circuit
and the battery's gas mixture could ignite.
make sure that you do not create an elec-
R
trostatic charge, e.g. by wearing synthetic
clothing or as a result of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials.
never touch the battery first. To discharge
R
a possible electrostatic charge, step out of
the vehicle first and touch the bodywork.
do not wipe the battery using a cloth. The
R
battery may explode as a result of electro-
static charge or due to flying sparks.

Switch off the engine and remove the key
before disconnecting the terminal clamps
from the battery. On vehicles with KEY-
LESS-GO, make sure that the ignition is
switched off. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, you may destroy electronic
components, such as the alternator.

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
carry out work on batteries yourself, e.g.
removing, charging or replacing. Always have
this work performed at a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre.
