The battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat.
WARNING
Pay attention to the warning instructions relating to working in the en-
■
gine compartment
» page
137.
A discharged vehicle battery may already freeze at temperatures just be-
■
low 0 °C. If the battery is frozen, do not jump start with the battery of an-
other vehicle – there is a risk of explosion.
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
■
away from the battery – risk of explosion!
Never jump-start vehicle batteries with insufficient acid levels – risk of
■
explosion and chemical burns.
The vent screws of the battery cells must be tightened firmly.
■
Note
We recommend you buy jump-start cables from a car battery specialist.
Jump-starting using the battery from another vehicle

Jump-starting: A – flat battery, B
– battery providing current
Read and observe
on page 163 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
to the positive terminal of the discharged battery

.
A
›
Attach clamp
to the positive terminal of the battery supplying power
2
›
Attach clamp
to the negative terminal of the battery supplying power
3
›
Attach the clamp
to a solid metal component firmly connected to the en-
4
gine block or to the engine block itself.
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, halt the attempt to start the engine after 10 sec-
onds and wait for 30 seconds before repeating the process.
›
Remove the jumper cables exactly in the reverse sequence as for clamping.
On vehicles with the START-STOP system, the jump-start cable of the charger
must never be connected directly to the negative pole of the vehicle battery,
but only to the engine earth.

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.
