Starting with a donor battery
The battery is fitted in the rear of the car (see
page 216) but there are also connection points
under the bonnet.
If the battery is flat 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. Turn the remote control key to key position
0.
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. Connect the red jump lead's other clamp
onto the car's positive terminal (2).
> A spring-loaded cover over the car's
extra positive terminal must first be
folded up!
6. Connect one of the black jump lead's
clamps to the donor battery's negative ter-
minal (3).
7. Fit the second clamp on a grounding point
e.g. one of the engine's lifting eyes (4).
8. Check that the jump lead clamps are
affixed securely so that there are no sparks
during the starting procedure.
9. 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.

10. 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.
11. 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 con-
nected 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 immediately.
