Jump-starting
153
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. Only use jumper cables with
fully insulated handles on the terminal
clamps.
2. Connect one terminal clamp of the
plus/+ jumper cable to the positive
terminal of the battery or to an auxil-
iary jump-starting terminal of the
support vehicle
3. Connect the second terminal clamp
of the plus/+ jumper cable to the
positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be started
4. Your BMW is equipped with a special
nut – see arrow 2 – to serve as the
ground or negative terminal.
Attach a terminal clamp of the
minus/– jumper cable to the negative
terminal of the support vehicle's bat-
tery or to a suitable ground on its
engine or bodywork
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
