WARNING
Electrostatic build-up can leadtot he creation
of sparks, which could ignite the highlye xplo-
sive gases of abattery. There is arisk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highlyf lammable gas mixture forms when
charging the battery as wellasw hen jump-
starting.
Alwaysm ake sure that neither you nor the
battery is electrostatically charged. Abuild-
up of electrostatic charge can be caused, for
example:
R by wearing clothing made from synthetic
fibers
R due to friction betwee nclothing and seats
R if you push or pullt he battery across the
carpet or other synthetic materials
R if you wipet he battery with acloth G
WARNING
During the charging process, abattery produ-
ces hydrogen gas. If ashort circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is arisk of an explosion.
R Make sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
R Never place metal objects or tools on abat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting abattery.
R When jump-starting, make sure that the
battery polesw ith identical polarity are
connected. R
It is particularly important to observe the
describe dorder when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals whilet he engine is running. G

WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the battery. Keep children away from batteries. Wash battery acid immediately with water and seek
medical attention. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery 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 jumper cables.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy startinga
ttempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
Do not start the vehicle using arapid charging device. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from asecond battery using jumper
cables. Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using asecond battery or ajump-starting device.
R You may only jump-start the vehicle when the engine and exhaust system are cold.
R Do not start the engine if the battery is frozen.L et the battery thaw first.
R Only jump-start from batteries with a12Vvoltage rating.
R Only use jumper cables which have asufficient cross-section and insulated terminal clamps. 242
