Jump-starting using the battery from another vehicle
Fig. 344 Jump-starting: - discharged battery, - power-supplying
battery/ground point of the engine for the START-STOP system
Fig. 345
Positive terminal on vehicles
with the vehicle battery in the
luggage compartment
Read and observe
on page 293 first.
If it is not possible to start the engine due to a discharged vehicle battery, the
battery of another vehicle can be used to start the engine. Only use jump-start
cables which have an adequately large cross-section and insulated terminal
clamps.
The rated voltage of the two batteries must be 12V. The capacity (Ah) of the
current-giving battery must not be significantly less than the capacity of the
discharged battery in your vehicle.
The jump-start cables must be attached in the following sequence.
›
Attach clamp
1
to the positive terminal of the discharged battery.
›
Attach clamp
2
to the positive terminal of the current-giving battery.
›
Attach clamp
3
to the negative terminal of the current-giving battery.
›
For vehicles with the START-STOP system, secure the clamp
4
to the
ground point of the engine
A
» Fig. 344.
›
For vehicles without the START-STOP system, secure the clamp
4
to a solid
metal part that is firmly attached to the engine block or secure to the engine
block directly.
Installation location of the positive terminal and the earth point in vehicles
with the vehicle battery in the luggage compartment
The positive terminal
B
is located under a cover in the engine compartment
» Fig. 345.
›
Open the cover in the direction of the arrow.
›
Clamp the positive terminal of the jumper cable to the position
B
» Fig. 345.
›
Clamp the negative terminal of the jumper cable to the earth point of the en-
gine
A
» Fig. 344 or on a metal part firmly connected to the engine block or
directly on the engine block.
Starting engine
›
Start the engine on the vehicle providing the power and allow it to idle.
›
Start the engine in the vehicle with the discharged battery.
›
If the engine does not start within 10 s, then cancel the starting procedure
and repeat after half a minute.
›
Remove the jump start cables in the reverse order as attachment.
WARNING
■
Never clamp the jump-start cable to the negative terminal of the dis-
charged battery - danger of explosion.
■
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 vehi-
cle – risk of short circuit!
■
Route the jumper cables so that they cannot be caught in rotating parts in
the engine compartment - danger of injuries and the risk of vehicle dam-
age.
