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‐
te ry cla mp s while the engine is running. &
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 may be released. #
Alwaysth aw a frozen battery out first
before charging it or per form ing starting
assis tance. 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 thest art-up behavior may de teriorate, partic‐
ularly at low temp eratures

insula tedte rm inal clamps
R non-insulated parts of thete rm inal clamps
must not come into con tact wi thother me tal

instructions foryo ur charge r before charging
th e batter y.
Obser vethe additional following points during
