NOTE
In the case of body contact between the
two vehicles, a short circuit can occur during
jump-starting. There is a risk of property dam‐
age. Make sure that no body contact occurs.◀
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.
2. Switch off the engine of the assisting vehi‐
cle.
3. Switch off any electronic systems/power
consumers in both vehicles.
Starting aid terminals
The starting aid terminal in the engine com‐
partment acts as the battery's positive termi‐
nal.
Open the cover of the starting aid terminal.
A special nut serves as the negative terminal of
the battery.
Connecting the cables
Before you begin, switch off all unnecessary
electronic systems/power consumers, such as
the radio, on the assisting and receiving vehi‐
cle.
1. Open the cover of the starting aid terminal.
2. Attach one terminal clamp of the positive
jumper cable to the positive terminal of the
battery, or to the corresponding starting
aid terminal of the vehicle providing assis‐
tance.
3. Attach the terminal clamp on the other end
of the cable to the positive terminal of the
battery, or to the corresponding starting
aid terminal of the vehicle to be started.
4. Attach one terminal clamp of the negative
jumper cable to the negative terminal of
the battery, or to the corresponding engine
or body ground of assisting vehicle.
5. Attach the second terminal clamp to the
negative terminal of the battery, or to the
corresponding engine or body ground of
the vehicle to be started.
Establishing drive-ready state
1.
Start the engine of the assisting vehicle
and let it run for several minutes at an in‐
creased idle speed.
2. Establish the drive-ready state for the vehi‐
cle to be started as usual.
If the first starting attempt is not success‐
ful, wait a few minutes before making an‐
other attempt in order to allow the dis‐
charged battery to recharge.
3. Disconnect the jumper cables in the re‐
verse order.
Check the battery and recharge, if needed.
