Important safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle. Have testing
and service procedures performed by
specially-qualified technicians only. In
the event of a malfunction, deactivation,
or triggered actuation (as a response to
an accident) of the airbag restraint sys-
tem, consult your authorized BMW cen-
ter for repairs or service operations.

Modifications may not be made on ei-
ther the wiring or the individual compo-
nents in the airbag system. These in-
clude the padded steering wheel hub,
the instrument panel, the side trim pan-
els of the front or rear doors and the
roof pillars or the sides of the headliner.
Never apply adhesive materials to these
components or cover or modify them in
any way. Do not attempt to remove or
dismantle the steering wheel.
To ensure compliance with official
safety regulations, entrust disposal of
airbag generators to an authorized
BMW center.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury.< Consult your BMW center regarding the
required special procedures if you in-
tend to store the vehicle for longer than
three months.

Jump-startingNever use spray starter fluids to start
the engine.
If the battery is discharged, you can use
two jumper cables to start your car with
power from the battery of a second ve-
hicle. Always use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
There is a risk of fatal injury if you do
this.<
Carefully comply with the following in-
structions to avoid personal injury and
damage to one or both vehicles:
1 Ensure that the battery on the sup-
port vehicle is also rated at 12 volts,
and that the capacities of the two
batteries (Ah) are roughly comparable
(printed on casing)
2 Leave your battery connected to the
car electrical system
3 Make sure that there is no contact
between the bodywork of the two ve-
hicles – short circuit risk.
4 Start by connecting the jumper cable
from the positive terminal of the sup-
port vehicle to the positive terminal
connector located in your BMW's en-
gine compartment. The cover of the
auxiliary terminal for jump starting is
marked with "Batt. +" (refer to the il-
lustration). Remove by pulling tab.
The illustration shows the auxiliary
terminal for jump starting the BMW
740i/L as an example. For the BMW
750iL: Refer to "Engine compart-
ment" on page 140380de089
5 Then connect the negative terminals.
Attach the cable to either the support
vehicle's negative battery terminal,
or to a suitable ground on its engine
or bodywork. Then connect the other
end of the cable to ground on the ve-
hicle's engine or bodywork which is
to be started. Then connect the other
end of the cable to a ground on your
vehicle's engine or bodywork (for in-
stance, the nuts on the strut dome.
Refer to the arrows in the illustration
above)
Follow the same sequence for
connecting the jumper cables if
you assist in jump-starting another ve-
hicle. If you do not, there is a risk of in-
jury caused by spark generation at the
battery.< 380de117
