Electros tatic charge can cause spa rks which
may ignite the highly flammable gas mixture
in the batter y. #
Todischar geany electrostatic charge

flammable gas mixture is created while
th e battery is charging and when jump-s tarting. &
WARNING Danger of chemical burns
from the battery acid
Battery acid is caustic. #
Avoid contact with the skin, eyes or
clo thing. #
Do not lean overth e batter y. #
Do not inhale battery gases. #
Keep children away from the batter y. #
Immedia tely rinse battery acid off thor‐

WARNING Risk ofexplosion from hydro‐
ge nga s igniting
A battery generates hydrogen gas during the
ch arging process. If there is a short circuit or
spar ksstart toform ,th ere is a danger of the
hy drogen gas igniting. #
Make sure that the positive term inal of
th e connected battery does not come
into contact with vehicle parts. #
Never place me tal objects or tools on a
batter y. #
When connecting and disconnecting the
batter y,yo u must obse rveth e described
order forth e battery clamps. #
When giving starting assistance, alw ays
make sure that you on lyconnect battery
te rm inals with identical polarity. #
During starting assis tance, you must
obse rveth e described order for con‐
necting and disconnecting the jumper
cables. #
Do not connect or disconnect the bat‐

WARNING Risk ofexplosion during
ch arging process and starting assis tance
During thech arging process and starting
assis tance, the battery may release an explo‐
sive gas mixture. #
Avoid fire , open flames, creating spar ks
and smoking. #
Make sure that there is suf ficient venti‐
lation du ring thech arging process and
during starting assis tance. #
Do not lean over a batter y. &
WARNING Risk ofexplosion from a fro‐
zen battery
A dischar ged battery may freeze at temp era‐
tures slightly abo veor below freezing point.
During starting assis tance or battery charg‐
ing, battery gas can be released. #
Always allow a battery tothaw before
ch arging it or per form ing starting assis‐
ta nce. If
th ewa rning/indicator lamps do not light up in
th e instrument display around or below freezing point, it is
very likely that the discharged battery
has frozen.
In this case, obser vethefo llowing points:
R Do not give theve hicle starting assis tance or
ch arge the battery
R The service life of a battery that has been
th awe d may be reduced drastically
R The start-up behavior may de teriorate, partic‐
ularly at low temp eratures
