Jump-starting

Plug-in hybrid: be sure to read the separate Owner's Manual. You could otherwise fail to recognise

dangers, e.g. due to high voltage.

For the jump-starting procedure, use only the jump-starting connection point, consisting of a pos-

itive terminal and an earth point, in the engine compartment.

G WARNING

Battery acid is caustic. There is a risk of injury.

Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over

the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid

thoroughly with plenty of clean water and seek medical attention at once.

G WARNING

During charging and jump-starting, explosive gases can escape from the battery. There is a risk

of an explosion.

Particularly avoid fire, naked flames, creating sparks and smoking. Ensure there is sufficient

ventilation while charging and jump-starting. Do not lean over a battery.

G WARNING

Breakdown assistance

During the charging process, a battery produces hydrogen gas. If a short circuit occurs or sparks

are created, the hydrogen gas can ignite. There is a risk of an explosion.

R Make sure that the positive terminal of a connected battery does not come into contact with

vehicle parts.

R Never place metal objects or tools on a battery.

R It is important that you observe the described order of the battery terminals when connecting

and disconnecting a battery.

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

A discharged 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 a risk of an explosion.

Allow the frozen battery to thaw out before charging it or jump-starting.

! Vehicles with a petrol engine: avoid repeated and lengthy starting attempts. Otherwise, the

non-combusted fuel may damage the catalytic converter.

If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-

charged battery has frozen. In this case you may neither jump-start the vehicle nor charge the

battery. The service life of a battery that has been thawed may be reduced. The starting charac-

teristics may be impaired, especially at low temperatures. Have the thawed battery checked at a

qualified specialist workshop.
