53 Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Head airbags for driver and front pas-
senger
3Side airbags on the driver and pas-
senger sides – front and rear*Protective effectThe front airbags protect the driver and
passenger in the event of a head-on
collision where the protection provided
by the safety belt alone would not be
adequate. The head and side airbags
help provide protection in the event of a
collision from the side. The respective
side airbag helps support the seat
occupant's upper body.
For information on the correct sitting
position, refer to page 43.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
The airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not attempt to remove the air-
bag restraint system from the vehicle. In
the event of a malfunction, deactivation
or triggered activation – as a response
to an accident – of the airbag restraint
system, consult your BMW center for
inspection, repair or disassembly. Mod-
ifications may not be made on either
the wiring or the individual components
in the airbag system. These include the
upholstered covers on the steering
wheel, instrument panel, side trim pan-
els of the doors and front roof pillars,
and on the sides of the headliner. Do
not attempt to remove or dismantle the
steering wheel. Unprofessional
attempts to service the system could
lead to failure in an emergency or
undesired airbag activation, either of
which could result in personal injury. Do
not touch the individual components
directly after the system has been trig-
gered, as otherwise there is a danger of
burns.<

Jump-startingWhen 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 high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery

cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
