terminal of the donor battery. Never connect the
black negative cable directly to the battery.
6. Connect the black negative cable to the ground
point – .
7. Let the engine of the donor vehicle run at a
higher engine speed.
8. Start the engine. An attempted start using
jumper cables should not last more than 15 sec-
onds. Then wait for at least one minute.
9. With engine running:
First, disconnect the black negative cable from
the ground point – , then from the negative ter-
minal on the donor battery.
10. With engine running:
Disconnect the red positive cable from the pos-
itive terminal of the donor battery first, then from
the positive terminal for emergency starting + .
Emergency starting a lithium
battery
b b Vehicle with lithium battery
The 12-volt lithium battery is automatically discon-
nected from the vehicle electrical system if the bat-
tery charge condition is low. The electrical system is
deactivated temporarily. When the battery is
charged (for at least 10 minutes) or when emer-
gency starting or connection to an external power
supply take place, the electrical system is automati-
cally reactivated. The 12-volt lithium battery is au-
tomatically connected to the vehicle electrical
supply again.
The battery of another vehicle can be used for
starting and as an external power supply with the
help of jumper cables. Both batteries must have a
nominal voltage of 12 V. The capacity (Ah) of the
donor battery must not be substantially less than
that of the flat battery. The discharged battery must
be connected correctly to the vehicle's electrical
system.
> Please see chapter "Battery" on page 69.
Repeated emergency starting under normal operat-
ing conditions may indicate that the battery is
damaged.
WARNING
Unsuitable jumper ca-
bles and following incor-
rect procedures
Starting the vehicle using unsuitable jumper cables
or following incorrect procedures can cause short
circuits. The short circuit can cause a fire.
e Use only standard jumper cables with sufficient
cross section and completely insulated clamps.
Follow the instructions provided by the jumper
cable manufacturer.
e The vehicles must not touch, otherwise current
may flow as soon as the positive terminals are
connected.
e
Ensure that conductive jewelry (e.g. rings,
chains, watch straps) do not come into contact
with live parts of the vehicle.
e
Never connect jumper cables directly to the bat-
tery. Only connect jumper cables to the emer-
gency starting terminals.
WARNING
Escaping electrolyte fluid
and toxic gas
Risk of electrolyte fluid and toxic gases escaping in
exceptional cases if the battery is damaged or
handled incorrectly.
e Avoid any inhalation of the vapors and any skin
contact with the electrolyte fluid.
e Keep people away and on the side facing into the
wind.
e Only charge lithium batteries in well-ventilated
spaces.
NOTICE
Risk of damage if emergency starting an exhaus-
tively discharged lithium battery.
e
If you suspect that the lithium battery is ex-
haustively discharged, do not start the vehicle
using jumper cables.
