Jump-starting using the battery from another vehicle
First read and observe the introductory information and safety warn-
ings
on page 228.
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
›
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 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 battery
supplying the power must not be significantly less than the capacity of the dis-
charged battery in your vehicle.
Jump-start cables
Only use jump-start cables which have an adequately large cross-section and in-
sulated terminal clamps. Observe the manufacturer's instructions.
Positive cable - colour coding in the majority of cases is red.
Negative cable - colour coding in the majority of cases is black.
