WARNING
A discharged vehicle battery may already freeze at temperatures just be-
■
low 0 °C. If the battery is frozen, do not carry out a jump start with the bat-
tery of another vehicle – risk of explosion!
Pay attention to the warning instructions relating to working in the en-
■
gine compartment
» page
189.
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!
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.
Route the jump-start cables so that they cannot be caught by any rotat-
■
ing parts in the engine compartment.
Do not bend over the battery – risk of caustic burns!
■
The vent screws of the battery cells must be tightened firmly.
■
Keep any sources of ignition (naked flame, smouldering cigarettes, etc.)
■
away from the battery – risk of explosion!
Never jump-start vehicle batteries with an electrolyte level that is too low
■
– risk of explosion and caustic burns.
There must not be any contact between the two vehicles otherwise cur-
■
rent may flow as soon as the negative terminals are connected.
CAUTION
The discharged battery must be properly connected to the system of the ve-
■
hicle.
We recommend you buy jump-start cables from a car battery specialist.

Jump-starting using the battery from another vehicle
Read and observe
and
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
1
» Fig. 201
.
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 part which is connected firmly 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, terminate the attempt to start the engine after
10 seconds and wait for 30 seconds before repeating the process.
›
Disconnect the cables in exactly the reverse order to the one described
above.
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.
