WARNING
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.
Pay attention to the warning instructions relating to work in the engine
■
compartment » page 140.
The non-insulated parts of the terminal clamps must never touch each
■
other – there is a 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
– there is a 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 – there is a 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 insufficient acid levels – risk of
■
explosion and chemical burns.
CAUTION
There must not be any contact between the two vehicles otherwise current
■
may flow as soon as the negative terminals are connected.
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 battery of another vehicle can be used to jump-start your vehicle if the en-
gine will not start because the battery is flat. Jump-start cables are required for
this purpose.
The jump-start cables must be attached in the following sequence.
›
Attach clamp to the positive terminal of the discharged battery
1
» Fig. 149.
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 clamp to a solid metal component firmly connected to the engine
4
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.
›
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. Obey the instructions of the jump start cable manu-
facturer.
Positive cable - colour coding in the majority of cases is red.
