Active steering
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low speed range,
e.g. in a town or when parking, the steering
angle is increased, i.e. steering becomes very
direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to th e steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simult aneously deactivated
when DSC is switched off, refer to page 89.
Malfunction
The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivate d. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. Th e stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deacti vated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initializ ation may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding text mes-
sage appears. Have the system checked.
Servotronic
The concept
The Servotronic varies the steering force
required to turn the wh eels relative to the
vehicle speed.
At low speeds, the steering force is strongly
assisted, i.e. less force is needed for steering.
As the vehicle speed increases, the steering
assisting power is reduced.
This system functions automatically.
Malfunctions
The warning lamp lights up. A mes-
sage appears on the Control Display.
Servotronic is malfunctioning or has
failed. Steering response will be different. You
can continue your journey, but moderate your
speed and exercise due caution. Have the
system checked as soon as possible.
Brake Force Display
On the left: normal braking.
On the right: sharp braking.
When the rear fog lamps are switched on, the
Brake Force Display is no t active and the illumi-
nated area for normal braking is reduced by
approximately half.

Airbags
The following airbags are located under the
marked covers:
1
Front airbags
2 Coupe: head airbags
3 Side airbags in the seat backrests
4 Convertible: knee airbags
Protective action
Observe the adjustment instructions on
page 49 to ensure the best possible
personal 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 restrain t. 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 si tuation, 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.
Keep the dashboard and window on the front
passenger side clear, i. e., do not cover with
adhesive labels or coveri ngs, and do not attach
holders such as for navigation instruments and
mobile phones.
Do not attach seat cove rs, cushions or other
objects not specifically approved for seats with
integral side airbags to the front seats. Do not
hang items of clothing su ch as coats or jackets over the backrests. Do
not attempt to remove
the airbag retention system from the vehicle. Do
not modify the individu al components of the
system or its wiring in any way. This includes
the upholstered 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 faults, immobilization, or after the
airbag system has been triggered, only have the
testing, repair, or disa ssembly and scrapping of
gas generator performed by your BMW center
or a workshop that has the required explosives
licenses. Unprofessional attempts to work on
the system could lead to failure in an emer-
gency or to undesired ai rbag activation, either
of which could result in personal injury. <
Warning notices and information about the
airbags can also be found on the sun visors.
Automatic deactivation of the front
passenger airbags
An analysis of the impr ession in the front pas-
senger seat cushion determines whether and
how the seat is occupied. The front and side air-
bags for the front passe nger are activated or
deactivated by the system accordingly.
The indicator lamp above the interior
rearview mirror shows the current status
of the front passenger ai rbags, deactivated or
activated, refer to Sta tus of front passenger
airbags below. <

ControlsTechnology for driving comfort and safety
Before transporting a child on the front
passenger seat, read the safety precau-
tions and handling inst ructions under Trans-
porting children safely, refer to page 58.
The front and side airbags can also be deacti-
vated by adolescents and adults sitting in cer-
tain positions; the indi cator lamp for the front
passenger airbags lights up. In such cases, the
passenger should change his or her sitting
position so that the fr ont 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 front and side airbags in accordance
with whether and how the front passenger seat
is occupied. The indicator lamp shows whether
the front passenger airbags are activated or
deactivated.
>The indicator lamp lights up when a child in
a specially designated child restraint sys-
tem is detected, as in tended, on the seat.
The front and side airbags for the front
passenger are not activated. Most child seats are detected by the
system. This partic
ularly applies to
child seats that were required by NHTSA at
the time of manufacture of the vehicle. After
mounting a child seat, ensure that the indi-
cator lamp for the fron t passenger airbag is
lit. It indicates that th e child seat has been
detected and that the front passenger air-
bags are deactivated. <
> The indicator lamp does n o t c o m e o n w h e n ,
for example, a person of sufficient size and
in a correct sitting position is detected on
the seat.
The front and side airbags for the front
passenger are activated.
> The indicator lamp does not light up if the
seat is empty.
The front and side airbags for the front
passenger are not activated.
Operational readine ss of airbag system
As of radio readiness, refer to page 61, the
warning lamp lights up br iefly 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 withou t delay; otherwise,
there is the risk that th e 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 of suf-
ficient severity or an extreme tilt in the car's lon-
gitudinal axis. The protection bars behind the
rear head restraints depl oy within fractions of a
second.
As a supplementary system to the reinforced
windshield frame, the rollover protection
system increases the safety of the 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 sa fety 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.
If the rollover protective system is
extended, do not operate the convertible
top.
Do not make any modifica tions to the individual
components of the rollover protection system
or its cabling.
Work on the rollover protection system should
be performed only by your BMW center.
Faulty repair may lead to the failure of the sys-
tem or malfunctions.
To check the system and ensure flawless long-
term operation, always observe the service
intervals, refer to page 80.<

General information
When the driver's door is opened with ignition
switched off, then the exterior lighting is auto-
matically switched off if the light switch is in
position 0, 2 , or 3.
Parking lamps
In switch position 1, the front, rear and side
vehicle lighting is switch ed on. You can use the
parking lamps for parking.
With halogen headlamps: when the ignition is
switched off and the sw itch is in position 1, only
the outside sections of the rear lamps are illumi-
nated, refer to page 246.
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 enou gh power to start the
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps,
refer to page 102.<
Low-beam headlamps
The low beams light up wh en the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
When the switch is in position 3, the low beams
are switched on and off automatically depend-
ing on ambient lighting conditions, e.g. in a tun-
nel, in twilight, or if there is precipitation. The
Adaptive Light Control is active. The LED next
to the symbol is illu minated when the low
beams are on. You can also activate the daytime
running lights, refer to page 101. In the situa-
tions described above, the lamps then automat-
ically switch from daytime running lights 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 ma
nually under these
conditions.<
Welcome lamps
If you leave the light switch in position 2 or 3
when you park the car, the parking lamps and
the interior lamps light up briefly when you
unlock the vehicle.

angle and other parameters, the light from the
headlamp follows the course of the road.
In tight curves such as on switchbacks or when
turning, at speeds up to approx. 40 mph/
70 km/h, an additional, cornering light is
switched on that lights up the area inside the
curve.
Activating Adaptive Light Control
With the ignition switched on, turn the light
switch to position 3, refer to page 100.
The corner-illuminating lamp is switched on
automatically, depending on the steering wheel
angle or turn signal indicator.
Standstill function: to avoid blinding oncoming
traffic, the Adaptive Light Control does not
direct light toward the driver's side when the
vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are switched on and active on
both sides.
Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Display.
The Adaptive Light Control is mal-
functioning or failed. Ha ve the system checked
as soon as possible.
High beams/roadside parking
lamps
1 High beams
2 Headlamp flasher
3 Roadside parking lamps
Roadside parking lamps, left or right
There is an additional option of switching on the
lamps on the side of the car facing the road
when parked.
Switching on
After parking the vehicle, press the lever up or
down beyond the pressu re point for approx.
1 second, arrow 3.
The roadside parking lamps drain the bat-
tery. Therefore, do not leave them on for
unduly long periods of time; otherwise, the bat-
tery might not have enou gh power to start the
engine. <
Switching off
Press the lever in the o pposite direction to the
pressure point, arrow 3.
High-beam Assistant
The concept
This system automatically switches the high
beams on and off. The procedure is controlled
by a sensor on the front of the interior rearview
mirror. The assistant ensures that the high
beams are switched on whenever the traffic sit-
uation allows. It handle s this task for you and
gives you the benefit of the best possible view.
You can intervene at any time and switch the
high beams on and off as usual.
Activating the system
1. Turn the light switch to position 3, refer to
page 100.
2. With the low beams switched on, briefly
push the turn signal/high beam lever in the
direction of the high beam.
The indicator lamp in the instrument
cluster lights up when the high beams
are activated. The system automati-
cally switches from hi gh beams to low beams

and vice versa in response
to oncoming traffic,
traffic ahead of you, and adequate ambient
lighting, e.g. on city streets.
Switching the high beams on and off
manually
Whenever you wish, or when the situation
requires, you can intervene:
> If the High-beam Assistant switches on the
high beams, but you would like to drive with
the low beams, simply switch off the high
beams using the turn signal/high beam
lever. This deacti vates the High-beam
Assistant.
To reactivate the syst em, briefly push the
turn signal/high beam lever toward the high
beams again.
> If the High-beam Assistant switches on the
low beams, but you would like to drive with
the high beams, switch on the high beams
as usual. This deacti vates the system and
the high beams need to be switched off
manually, if necessary.
To reactivate the syst em, briefly push the
turn signal/high beam lever toward the high
beams again.
> Use the headlamp flasher as usual with the
low beams switched on.
System limitations
The High-beam Assistant cannot serve
as a substitute for the driver's personal
judgment of when to use the high beams.
Therefore, manually switch off the high beams
in situations where this is required to avoid a
safety risk.<
The system is not fully fu nctional in situations
such as the following, and driver intervention
may be necessary:
> In very unfavorable weather conditions,
such as fog or heavy precipitation
> In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings >
In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on highways
> In poorly lit towns and cities and in the
presence of highly reflective signs
> At low speeds
> When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov-
ered with stickers, etc.
> If the sensor is dirty. Clean the sensor on
the front of the interior r e a r v i e w m i r r o r u s i n g
a cloth moistened with a small amount of
glass cleaner.
