Centre or to a special collection point for
old batteries. 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 pre-
vent vehicle occupants from suffering acid
burns should the battery be damaged in the
event of an accident.
To prevent acid burns, observe the follow-
ing safety notes when handling batteries:
R Do not lean over batteries.
R Do not place any metal objects on a bat-
tery. You could otherwise cause a short
circuit and the battery's gas mixture
could ignite.
R Make sure that you do not create an elec-
trostatic charge, e.g. by wearing syn-
thetic clothing or as a result of friction on
fabrics. Therefore, you should not pull or
slide the battery over carpets or other
synthetic materials.
R Never touch the battery first. To dis-
charge a possible electrostatic charge, step out of the vehicle first and touch the
bodywork.
R Do not wipe the battery using a cloth. The
battery could be destroyed as a result of
electrostatic charge or due to flying
sparks.
! Switch off the engine and remove the key
before disconnecting or removing the ter-
minal clamps from the battery. You may
otherwise destroy electronic components,
such as the alternator.
i Mercedes-Benz recommends that you
have all work involving the battery, e.g.
removing, charging and replacing, carried
out at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.
Installation location of the battery Your vehicle is equipped with a battery in the
footwell in front of the front-passenger seat.
