tem
Read and observe on page 219 first.
The starting process using the battery of another vehicle requires the use of
jumper cables.
The jump-start cables must be attached in the following sequence.
›
Attach clamp
1
to the positive terminal of the discharged battery
A
» Fig. 224 .
›
Attach clamp
2
to the positive terminal of the battery supplying power

.
›
Attach clamp
3
to the negative terminal of the battery supplying power
B
.
›
Attach the clamp
4
to a solid metal part which is connected firmly to the en-
gine block or to the engine block itself.
On vehicles with the START-STOP system» Fig. 225, connect the jump-start
cable to the engine's earthing point.
Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Start the engine of the vehicle with the discharged battery.
›
If the engine does not start, terminate the attempt to start the engine after
10 seconds and wait for 30 seconds before repeating the process.
›
Remove the jump-start cables exactly in the reverse sequence as for attach-
ing.
Both batteries must have a rated voltage of 12 V. The capacity (Ah) of the bat-
tery supplying the power must not be significantly less than the capacity of
the discharged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and
insulated terminal clamps. Observe the instructions of the jumper lead manu-
facturer.
Positive cable – colour coding in the majority of cases is red.

Negative cable – colour coding in the majority of cases is black.
WARNING
■
Do not clamp the jump-start cable to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being star-
ted.
■
The non-insulated parts of the terminal clamps must never touch each
other – risk of short circuit!
■
The jump-start cable connected to the positive terminal of the battery
must not come into contact with electrically conducting parts of the vehicle
– risk of short circuit!
■
Route the jump-start cables so that they cannot be caught by any rotat-
ing parts in the engine compartment.
