Jump starting with another battery
If the starter battery (p. 391) is discharged then
the car can be started with current from another
battery.
When jump starting the car, the following steps
are recommended to avoid short circuits or other
damage:
1. Set the car's electrical system in key position
0, see Key positions - functions at different
levels (p. 84).
2. Check that the donor battery has a voltage of
12 V.
3. If the donor battery is installed in another car
- switch off the donor car's engine and make
sure that the two cars do not touch each
other.
4. Connect one of the red jump lead's clamps
to the donor battery's positive terminal (1).
IMPORTANT
Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.
5. Open the clips on the front cover of the bat-
tery in your car and remove the cover, see
Starter battery - replacement (p. 393).
6. Connect the red jump lead's other clamp
onto the car's positive terminal (2).
7. Connect one of the black jump lead's clamps
to the donor battery's negative terminal (3).
8. Connect the other clamp to a grounding
point, e.g. right-hand engine mounting at the
top, the outer screw head (4).
9. Check that the jump lead clamps are affixed
securely so that there are no sparks during
the starting attempt.
10. Start the engine of the "donor car" and allow
it to run a few minutes at a speed slightly
higher than idle approx. 1500 rpm.
11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the crocodile clips during the
start procedure. There is a risk of sparks
forming.
12. Remove the jump leads in reverse order -
first the black and then the red.
> Make sure that none of the black jump
lead's clamps comes into contact with the
battery's positive terminal or the clamp
connected to the red jump lead.
WARNING
•
The battery can generate oxyhydrogen
gas, which is highly explosive. A spark can
be formed if a jump lead is connected
incorrectly, and this can be enough for
the battery to explode.
•
The battery contains sulphuric acid, which
can cause serious burns.
•
If sulphuric acid comes into contact with
eyes, skin or clothing, flush with large
quantities of water. If acid splashes into
the eyes - seek medical attention imme-
diately.
