Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Coupe: head airbags, front and rear
3Side airbags in the seat backrests
Protective action
Observe the adjustment instructions on
page45 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags have been designed to not be trig-
gered in every collision situation, e.g. not in
minor accidents or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attach
seat covers, cushions or other objects not spe-
cifically approved for seats with integral side air-
bags to the front seats. Do not hang items of
clothing such as coats or jackets over the back-
rests. Do not attempt to remove the airbag
retention system from the vehicle. Do not mod-
ify the individual components of the system or
its wiring in any way. This includes the uphol-
stered covers on the steering wheel, instrument
panel, seats and roof posts, as well as the sides of the roof lining. Do not attempt to remove or
dismantle the steering wheel.
Do not touch the individual components imme-
diately after the system has been triggered,
because there is a danger of burns.
In the event of malfunctions, deactivation or
triggering of the airbag restraint system, have
the testing, repair, removal and disposal of air-
bag generators executed only by a BMW center
or a workshop that works according to repair
procedures of BMW with correspondingly
trained personnel and that has the required
explosives licenses. Unprofessional attempts to
work on the system could lead to failure in an
emergency or to undesired airbag activation,
either of which could result in personal injury.<
Warning notices and information about the air-
bags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impression in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passenger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger airbags, deactivated or
activated, refer to Status of front passenger air-
bags below.
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling instructions under Trans-
porting children safely, refer to page56.

Technology for driving comfort and safety
98 The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indicator lamp for the front
passenger airbags comes on. In such cases, the
passenger should change his or her sitting
position so that the front passenger airbags are
activated and the indicator lamp goes out. If the
desired airbag status cannot be achieved by
changing the sitting position, transport the rele-
vant passenger on a rear seat. Do not attach
seat covers, seat cushion padding, ball mats or
other items to the front passenger seat unless
they are specifically recommended by BMW.
Do not place any items under the seat which
could press against the seat from below. Other-
wise a correct analysis of the seat cushion is not
ensured.<
Status of front passenger airbags
The indicator lamp for the front passenger air-
bags shows the functional status of the front
passenger's front and side airbags in accor-
dance with whether and how the front passen-
ger seat is occupied. The indicator lamp shows
whether the front passenger airbags are acti-
vated or deactivated.
>The indicator lamp lights up when a child in
a specially designated child-restraint sys-
tem is detected, as intended, on the seat.
The front and side airbags for the front pas-
senger are not activated.
Most child seats are detected by the
system, especially child seats
required by the NHTSA at the time of vehi-
cle production. After mounting a child seat,
ensure that the indicator lamp for the front
passenger airbag is lit. It indicates that the child seat has been detected and that the
front passenger airbags are deactivated.
>The indicator lamp does not come on as
long as a person of sufficient size and in a
correct sitting position is detected on the
seat.
The front and side airbags for the front pas-
senger are activated.
>The indicator lamp does not come on if the
seat is empty.
The front and side airbags for the front pas-
senger are not activated.
Operational readiness of airbag system
As of radio readiness, refer to page59, the
warning lamp comes on briefly to indicate that
the entire airbag system and the belt tensioners
are operational.
Airbag system malfunction
>Warning lamp does not light up at radio
readiness or beyond.
>Warning lamp remains permanently on.
In the event of a fault in the airbag system,
have it checked without delay, otherwise
there is the risk that the system will not function
as intended even if a sufficiently severe acci-
dent occurs.<
Convertible: rollover
protection system
The rollover protection system is activated
automatically in the event of an accident, a crit-
ical driving situation, an extreme tilt in the car's
longitudinal axis or upon loss of ground contact.

The protection bars behind the rear head
restraints deploy within fractions of a second.
As a supplementary system to the reinforced
windshield frame, the rollover protection sys-
tem ensures that the necessary headroom is
maintained for all vehicle occupants.
Always keep the area of movement of the
rollover protection system clear.
In minor accidents, you are protected by the
fastened safety belt and, depending on acci-
dent severity, by the safety belt tensioner and
multi-phase airbag retention system.<
Resetting
If the rollover protection system was not
impacted after being automatically activated, it
can be reset by lowering the protection bars to
their original positions. This does not require
tools.
1.Push the locking lever to one side and hold
it there.
2.Push the protection bar halfway down from
above.
3.Release the locking lever.
4.Push the protection bar down until it snaps
into place.5.Repeat the procedure for the other protec-
tion bar.
Have the rollover protection system checked
after an unexpected activation.
Never move the retractable hardtop when
the rollover protection system is in the
activated position.
Do not make any modifications to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
only be performed by a BMW center.
Incorrectly performed work on the system may
lead to system failure or incorrect operation.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page79.<

When you open the driver's door with the igni-
tion switched off, the exterior lighting is auto-
matically switched off if the light switch is in
position 0, 2 or 3.
Switch on the parking lamps if necessary,
switch position 1.
Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for
unduly long periods of time, otherwise the bat-
tery might not have enough power to start the
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps,
refer to page102.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control*
When the switch is in position3, the low beams
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel,
in twilight, or if there is precipitation. The Adap-
tive Head Light
* is active. The LED next to the
symbol is illuminated when the low beams are
on. You can also activate the daytime running
lamps, refer to page101. In the situations
described above, the lamps then automatically
switch from daytime running lamps to low
beams.
The headlamps may also come on when the
sun is sitting low on a blue sky.
The low beams remain switched on inde-
pendent of the ambient lighting condi-
tions when you switch on the fog lamps.<
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the system
cannot detect fog or hazy weather. To avoid
safety risks, you should always switch on the
low-beam headlamps manually under these
conditions.<

Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables better illumination

Lamps
102 of the road surface. Depending on the steering
angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h,
e.g. on mountainous roads or when turning, an
additional, corner-illuminating lamp is switched
on that lights up the inside area of the curve.
Activating Adaptive Head Light
With the ignition switched on, turn the light
switch to position 3, refer to page100.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
To avoid blinding oncoming traffic, the Adaptive
Head Light directs light towards the front pas-
senger side when the vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are active and switched on on
both sides.
Malfunction
