Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a
positive terminal and an earth point, in the engine compartment. 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
ventilation 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 freezin gpoint .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 th evehicl ewhen th eenginea nd exhaust system are cold.
R Do no tstart th eengineift hebattery is frozen .Let th ebattery thaw first. 326
Jump-startingBreakdown assistance

R
Only jump-start from batteries with a12Vvoltage rating.
R Only use jumper cables which 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 before attempting to start. This charges the battery slightly.
R Make sure that the two vehicles do not touch.
Make sure that:
R the jumper cables are not damaged.
R when the jumper cables are connected to the battery, uninsulated sections of the terminal
clamp do not come into contact with other metal sections.
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.
