Jump-starting

When your battery is discharged you
can used two jumper cables to start
your vehicle with power from the bat-
tery in a second vehicle. You can also
use the same method to help start
another vehicle. Use only jumper cables
with fully-insulated clamp handles.

To avoid the risk of potentially
fatal injury, always avoid all con-

tact with electrical components while
the engine is running. Carefully observe
the following instructions to avoid per-
sonal injury and/or damage to one or
both vehicles.

Preparing

1. Check whether the battery of the

other vehicle has a voltage of
12 Volts and approximately the same
capacitance in Ah. This information
can be found on the battery

2. Switch off the engine of the support

vehicle

3. Switch off any electrical systems and

components in both vehicles.

Ensure that no contact exists
between the bodywork on the two

vehicles, otherwise there is a danger of
short circuits.

sparks, always observe this

sequence when connecting jumper
cables.

On your BMW the so-called jump-start
connection point in the engine com-
partment acts as the battery positive
