Do not use spray starter fluids to start
the engine.
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 handles on the terminal
clamps.
Do not touch the parts conducting
current while the engine is
running. Failure to comply with this
creates a risk of fatal injury.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles.<
1. Ensure that the battery in the support
vehicle is also rated at 12 volts. This
information is provided on the top of
the battery casing
2. Do not disconnect your battery from
your vehicle's electrical system.
Switch off all electrical accessories in
both vehicles
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles Ð short circuit
hazard
4. Start the engine on the support
vehicle and allow it to run
5. Use one jumper cable (+) to connect
the positive terminal of the battery in
the support vehicle with the auxiliary
positive terminal provided in the
engine compartment of your BMW
specifically for jump-starting. The
cover of the positive terminal
connector is marked with a "+" sign.
Refer to the illustration. Remove by
pulling the tab (arrow 1)
6. Next, connect one end of the other
jumper cable (-) to either the support
vehicle's negative battery terminal or
a suitable ground on its engine or
bodywork. Connect the other end to
the negative battery terminal or a
suitable ground on the vehicle being
started. There is a special nut
provided for this on the BMW
(arrow 2)
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.<
7. Allow the engine of the support
vehicle to run at a fast idle for several
minutes, then 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
8. Allow the engines to run for several
minutes before disconnecting the
jumper cables
9. Then disconnect the jumper cables
in the opposite order.
Have the battery recharged at your
BMW center as required.
