JUMP-STARTING

Preparation for jump-starting

1. Check whether the battery of the support

vehicle has 12 Volts and approximately
the same capacity (Ah) (printed on the
battery)

2. Switch off the engine of the support

vehicle

3. Switch off any electrical systems and

components in both vehicles – except
for the hazard warning flashers of the
support vehicle.
>

Do not disconnect the discharged
battery from the vehicle electrical
system

Make certain that there is no contact
between the bodywork of the two
vehicles – short circuit hazard!

4. With the battery of the MINI COOPER,

remove the cover panel. To do so, press
both clips at the same time
or
with the MINI COOPER S, open the cover
of the positive terminal connection (for
jump-starting)

, see arrow 1.

Connect the jumper cables

Adhere to the sequence also when
providing support for other vehicles;

failure to observe this procedure can lead
to sparks at the terminals and pose an
injury hazard.

1. On the MINI COOPER S, the positive

terminal connection (for jump-starting),
see arrow 1, functions as the positive
battery terminal.
Use the jumper cable (+) to set up a
connection between the positive terminal
of the discharged battery and the positive
terminal of the support battery

2. Use the second jumper cable (–) to set

up the connection between the negative
terminals of both vehicles.
To do so:
>

Connect one terminal clamp to the
negative terminal and/or to an engine
or body ground of the support vehicle

Connect the second terminal clamp to
the negative terminal of the battery
and/or to an engine or body ground of
the vehicle to be started. For the MINI,
see arrow 2.

Performing the jump-start

1. Start the engine of the vehicle providing

the current and allow to run at a fast idle
speed for several minutes

2. Start the engine on the vehicle with the

discharged battery in the usual manner.
>

If the first start attempt is not
successful, wait a few minutes before
another attempt in order to allow the
discharged battery to recharge.

On the MINI:
Before disconnecting the jumper

cables, switch on the lighting, rear window
defroster and the highest blower speed as
well as the engine for at least approx.
10 seconds to prevent a voltage surge from
the regulator to the electrical systems and
components.

3. Then disconnect the jumper cables in

the reverse order.

Depending on the cause of the
malfunction, have the battery

checked and recharged at your MINI
center.
