WARNING
A discharged vehicle battery may already freeze at temperatures just below
■
0 °C. In case of frozen battery carry out no jump-starting – risk of explosion!
Pay attention to the warning instructions relating to working in the engine

compartment
» page
108, Engine compartment.
The non-insulated parts of the terminal clamps must never make contact
■
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing 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 started.
Route the jump-start cables so that they cannot be caught by any rotating
■
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 an explosion!
Never jump-start vehicle batteries with an electrolyte level that is too low –
■
risk of explosion and caustic burns.
Note
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 vehi-
■
cle.
We recommend you buy jump-start cables from a car battery specialist.

Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Now 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 about 30 seconds before repeating the process.
