Jump-Starting; Connecting The Jumper Cables - BMW X5 2004 Owner's Manual

Jump-starting

When your battery is discharged you
can use two jumper cables to start your
vehicle with power from the battery 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.<

Connecting the jumper cables

To avoid personal injury from
sparks, always observe this
sequence when connecting jumper
cables.<
