Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circui toccurs or sparks
are created, the hydroge ngas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnecte dbattery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnect the battery terminals while the engine is running. G
WARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint .When jump-startin gthe
vehicle or charging the battery ,gases can escape from the battery. There is arisk of an explosion.

earapid charging device to start the vehicle. If your vehicle' sbattery is discharg ed,
the engine can be jump-starte dfroma nothe rvehicle or fr omasecon dbattery using jump
leads. Observe the following points:
R the battery is not acce ssiblein allvehicles .Ifthe other vehicle' sbattery is not accessible,
jump-start the vehicle using asecond batter yorajump-star ting device.
R vehicles with apetrol engine: only jump-star tthe vehicle when the engin eand exhaust
system are cold.
R do not start the engine if the battery is frozen. Let the battery thaw first.
R jump-starting may only be performed from batteries with anominal voltage of 12 V.
R only use jum pleads that have asufficient cross-section and insulated terminal clamps.
R if the battery is fully discharged, leave the battery that is being used to jump-start connected
for afew minutes befor eattempting to start. Thi scharges the empty battery alittle.
R make sure that the two vehicles do not touch.
Make sure that:
R the jump leads are not damaged.
R non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R the jump leads cannot come into contact with parts such as the V-belt pulle yorthe fan.
These parts mov ewhen the engin eisstarted and whil eitisr unning.
