G WARNING
During the charging process ,ab attery produces hydrogen gas. If as hort circui to ccurs or sparks
are created ,t he hydrogen gas can ignite. There is ar isk of an explosion.R
Make sure that the positive terminal of ac onnected battery does not come into contact with
vehicl ep arts.R
Never place metal objects or tools on ab attery.R
It is important that you observe the described order of the battery terminal sw hen connecting
and disconnecting ab attery.R
When jump-starting, make sure that the battery pole sw ith identical polarity are connected.R
It is particularl yi mportant to observe the described order when connecting and disconnecting
the jumper cables. R
Never connect or disconnect the battery terminal sw hile the engine is running.
G WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicl eorc harging the battery ,g ase sc an escap ef rom the battery .T here is ar isk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter coul db e
damaged by the non-combusted fuel.
If the indicator/warning lamp sdon ot light up at low temperatures, it is very likel yt hat the dis-
charge db attery has frozen. In this case, you may neither charge the battery nor jump-start the
vehicle. The service life of at hawed-out battery may be shorter. The starting characteristics can be
impaired ,p articularl yatl ow temperatures. Have the thawed-out battery checked at aq ualified
specialist workshop.
Do not start the vehicl eu sing ar api dc harging device. If you rv ehicle's battery is discharged, the
engine can be jump-started from another vehicl eorf rom as econd 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 ,j ump-
start the vehicl eu sing as econd battery or aj ump-starting device.R
You may only jump-start the vehicl ew hen the engine and exhaust system are cold.R
Do not start the engine if the battery is frozen. Let the battery thaw first. R
Only jump-start from batterie sw ith a12Vv oltag er ating.R
Only use jumper cables which have as ufficient cross-section and insulated terminal clamps.R
If the battery is full yd ischarged, leave the battery that is being used to jump-start connected for
af ew minutes before attempting to start. This charge st he battery slightly.R
Make sure that the two vehicles do not touch.
Make sure that: R
The jumper cables are not damaged. R
Bare parts of the terminal clamp do not come into contact with other metal parts while the jumper
cables are connected to the ba ttery.R
The jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan. X
