Jump-start terminals
The jump-start terminal in the engine compart-
ment acts as the positive battery terminal.
Jump-starting
General information
A special connection on the body in the engine
compartment acts as the negative battery ter-
minal.
If the battery is discharged, the engine can
be started using the battery of another vehicle
and two jumper cables. Only use jumper ca-
bles with fully insulated clamp handles.
Additional information:
Overview of engine compartment, refer to
page 297.
Safety information
Open the cover of the positive battery terminal.
DANGER
Connecting the cables
Before you begin, switch off all unnecessary
electronic systems/components such as the
radio on the assisting and receiving vehicles.
Contact with live components can lead to an
electric shock. There is a risk of injury or dan-
ger to life. Do not touch any components that
are under voltage.
1. Open the lid of the jump-start terminal.
2. Attach one terminal clamp of the positive
jumper cable to the positive battery termi-
nal, or to the corresponding jump-start ter-
minal of the vehicle providing assistance.
Warning
If the jumper cables are connected in the
incorrect order, spark formation may occur.
There is a risk of injury. Pay attention to the
correct order during connection.
3. Attach the terminal clamp on the other end
of the cable to the positive battery terminal,
or to the corresponding jump-start terminal
of the vehicle to be started.
Warning
4. Attach one terminal clamp of the negative
jumper cable to the negative battery termi-
nal, or to the corresponding engine or body
ground of assisting vehicle.
In the case of body contact between the two
vehicles, a short circuit can occur while jump-
starting. There is a risk of injury or risk of
damage to property. Make sure that no body
contact occurs.
5. Attach the second terminal clamp to the
negative battery terminal, or to the corre-
sponding engine or body ground of the ve-
hicle to be started.
Preparation
1. Check whether the battery of the other ve-
hicle has a voltage of 12 volts. The voltage
information can be found on the battery.
Starting the engine
Never use spray fluids to start the engine.
1. Start the engine of the assisting vehicle and
let it run for several minutes at an increased
idle speed.
2. Switch off the engine of the assisting vehi-
cle.
3. Switch off any electrical components in
both vehicles.
2. Start the engine of the vehicle that is to be
started in the usual way.
