JUMP-STARTING
Preparing for jump-starting
1. Check whether the battery of the sup-
port vehicle has 12 Volts and approxi-
mately the same capacity – measured in
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 bat-
tery 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 ter-
minal connection for jump-starting, see
arrow 1, functions as the positive bat-
tery terminal.
Make a connection with the "+" jumper
cable 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 suc-
cessful, 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.
If necessary have the battery checked and
completely charged at a MINI Dealer.
