WARNING
For safety reasons ,Mercedes-Benz recom-
mend stha tyou only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide

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 object sonabattery.
Otherwise, you could cause ashort 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 synthetic
clothin gorasar esult of friction on fabrics.
Therefore, you should not pull or slide the
battery over carpets or other synthetic
materials. R
