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. 0007
Make sure that the positive term inal of
th e connected battery does not come
into conta ct withvehicle parts. 0007
Never place me tal objects or tools on a
batter y. 0007
When connecting and disconnecting the
batter y,yo u must obse rveth e descri‐
bed order forth e battery clamps. 0007
When giving starting assis tance, al ways
make sure that you on lyconnect bat‐
te ry term inals with identical polarity. 0007
During starting assis tance, you must
obse rveth e described order for con‐
necting and disconnecting the jump
lead. 0007
Do not connect or disconnect the bat‐
te ry cla mp s while the engine is running. 000A
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. 0007
Avoid fire , naked flames, creating
spar ksand smoking. 0007
Make sure that there is suf ficient venti‐
lation du ring thech arging process and
during starting assis tance. 0007
Do not lean over a batter y. 000A
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, bat tery gas may be released. 0007
Alw aysth aw a frozen bat tery out first
before charging it or per form ing start‐
ing assis tance. If
th e indicator/warning lamps in the instrument
clus ter do not light up at low temp eratures, it is
ve ry likely that the dischar ged battery has fro‐
zen. In this case you may neither jump-s tart the
ve hicle nor charge the batter y.
The service life of a battery that has been
th awe d may be dramatically shor tened. The
st arting characteristics may be impaired, espe‐
cially at low temp eratures.
It is recommended that you ha veathaw ed bat‐
te ry checked at a qualified specialist workshop.
