57 Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Side 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 side airbags help pro-
vide protection in the event of a colli-
sion from the side. Each of the side air-
bags is designed to help support the
seat occupant's upper body.
For information on the correct sitting
position, refer to page 48.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated either at
the time of manufacture or by a BMW
center. You may have them activated if
you desire to do so. Please contact
your BMW center for additional infor-
mation.<
The airbags will not be triggered in
the event of a minor accident, cer-
tain vehicle rollover situations or colli-
sions from the rear.<
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. This includes the
upholstered covers on the steering
wheel, the instrument panel, the side
trim panels of the doors and front roof
pillars and on the sides of the front
headliner. Do not attempt to remove or
dismantle the steering wheel. Unpro-
fessional attempts to service the sys-
tem could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury. Do not touch the individual com-
ponents directly after the system has
been triggered, as otherwise there is a
danger of burns.<
At all times, occupants should sit
upright and be properly restrained
– infants and small children in appropri-
ate child-restraint systems; larger chil-
dren and adults using the safety belts.
Never let an occupant's head rest near
or on a side airbag because the inflating
airbag could cause a serious or fatal
injury. Please note that the word Airbag
imprinted on the door trim panel indi-
cates the airbag's location.
Accident research shows that the saf-
est place for children in an automobile
is in the rear seat. However, a child sit-
ting in the rear seat and not properly
restrained may place his or her head on
or near the side airbag, if so equipped.
For example, a child – even though
belted – may fall asleep with his or her
head against the side airbag. It may be
difficult for a driver to ensure that chil-
dren in the rear seat will remain prop-

If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the sys-
tem immediately.
Transporting children safely
Leave the rear safety belts in the
holders if they are not needed to
avoid unwanted movement from the
safety belts at high speeds.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems can increase the risk of injury to
children. Always read and follow the
instructions that come with the system.
Child-restraint system with tether
strapIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points have been provided –
refer to the arrows in the illustration.

Sequential M gearbox SMG II*The conceptThe sequential M gearbox SMG II is an
automated manual gearbox with which
clutching and shifting is assumed by an
electro-hydraulic system.
The SMG II is operated via two shift
paddles on the steering wheel and the
selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs, Drivelogic
>Gradient assistance, refer to page 74
>Upshift display and shift lights, refer
to page 75
>RPM matching on downshifts
>Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration
>Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces
>Operating safety through protection
against misshifting.Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
Selector lever positionR: Reverse position
0: Position 0 (Neutral)
Forward position with one-touch mode:
>S: sequential mode
>A: automated mode
>+: upshifting in sequential mode
>–: downshifting in sequential mode.
The SMG II is ready for operation from
ignition key position two or higher.
For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. 2 seconds after
engaging position 0 with the footbrake
depressed – Shiftlock function.

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward +
>To downshift, push the selector lever
forward toward –.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the SMG II
helps you think in the sequential mode:
>Upshifts and downshifts are only exe-
cuted when the new gear will provide
a suitable combination of vehicle and
engine speed, i.e., downshifts that
would cause the engine to overrev
will not be executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>When the speed is reduced, the
gearbox is automatically down-
shifted shortly before a gear-depen-
dent minimum speed is reached with-
out you taking any action.A – Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are automatically shifted.Changeover from sequential to auto-
mated mode: tap the selector lever to
the right toward A. Watch the display in
the instrument cluster, refer to page 72.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts in dependence on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

DrivelogicDrivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 72.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
from six driving programs ranging from
balanced, dynamic driving – 1 – to
sporty, puristic driving – 6. The sporty,
puristic driving program can only be
activated with the Dynamic Stability
Control (DSC) deactivated, refer to
page 87.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active. Exception:
instead of the last selected sequential
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Gradient assistanceThe gradient assistance enables start-
ing off on grades with virtually no roll-
back. It can be activated in the sequen-
tial and automated mode with the vehi-
cle stopped and can be used for both
forward and reverse driving.
The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
1. Depress footbrake with vehicle
stopped
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the gra-
dient assistance is activated
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within two seconds.
The gradient assistance must be reacti-
vated before each use.

86Technology for safety and driving convenience
Park Distance Control (PDC)*The conceptPDC assists you when you back into a
parking space. Acoustic signals alert
you to the momentary distance to an
object behind your vehicle. To do this,
four ultrasonic sensors in the rear
bumper measure the distance to the
nearest object. The range for the sen-
sors located at both rear corners ends
approx. 2 ft/60 cm behind the bumpers.
The range for the two middle sensors is
slightly less than 5 ft/1.50 m.
PDC is a parking aid that can
identify objects if they are
approached slowly, as is generally the
case when parking. Avoid driving
towards objects rapidly; due to underly-
ing physical principles, the system may
otherwise alert you too late for you to
take evasive steps.<
The system is activated automatically
about one second after you engage
reverse with the ignition key in
position 2.
Let this short period elapse before
driving backwards.<
PDC is deactivated when you shift back
out of Reverse.
You can have a signal set to con-
firm that the PDC has been acti-
vated.<
Acoustic signalsThe distance to the nearest object is
indicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the pres-
ence of an object less than 1 ft/30 cm
away.
The warning signal is canceled after
approx. three seconds if the distance to
the object remains constant during this
time – if you are moving parallel to
a wall, for instance.
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have your BMW center
resolve the problem.
PDC does not remove the driver's
personal responsibility for evaluat-
ing the distance between the vehicle
and any objects. Even when sensors
are involved, there is a blind spot in
which objects cannot be detected. This
applies especially in those cases where
the system approaches the physical
limits of ultrasonic measurement, as
occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or
wedge-shaped objects. Moreover, low
objects that have already been
detected – such as a curb edge – can
disappear out of the detection range of
the sensors before a continuous tone
sounds.
Loud sources of sound from outside or
inside the vehicle could drown out the
PDC signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they will continue to operate effec-
tively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Always maintain a distance of more
than 4 in/10 cm.<

Dynamic Stability Control (DSC)The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
The system starts up automatically
each time you start the engine.
The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks. Do not make any modifications to
the DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stabil-
ity. The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 19.
>Indicator lamp flashes: the system is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: the system has been
deactivated via the button or is
defective. You can continue to drive
the vehicle normally, but without
DSC. Please consult your BMW cen-
ter for repairs.
To deactivate the systemPress the button; the indicator lamp
comes on and stays on.
The vehicle does not execute the stabil-
ity-enhancement and traction-control
functions when DSC is deactivated.
We recommend that you deactivate the
system for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<

92Lamps
Parking lamps/Low beamsParking lamps
The front, rear and side vehicle
lighting is switched on. You can
use this to signal the position of
the vehicle when it is parked. For light-
ing on one side for parking as an addi-
tional feature, refer to page 93.
Low beams
When you switch the ignition off
with the low-beam headlamps
on, only the parking lamps will
remain on.
Follow me home lampsWhen you activate the headlamp
flasher after parking the vehicle and
switching off the lights, the low beams
will come on for a brief period.
You can also have this function
deactivated.<
LIGHTS ON warningWhenever you open the driver's door
after having turned the ignition key to
position 0, you will hear an acoustic
signal for a few seconds to remind you
that the lamps have not been switched
off.Daytime driving lamps*If you desire, the light switch can be left
in the low-beam position: when the
ignition is switched off, the external
lighting is also switched off.
Observe the legal regulations regarding
the use of daytime driving lamps.
When required, switch on the parking
lamps as usual as described under
Parking lamps.
You can have the activation set-
tings for the daytime driving lamps
programmed on your vehicle.<
Automatic headlamp control*
When the switch is in this posi-
tion, the system automatically
responds to changes in ambient
light – in tunnels, at dusk, etc. – and to
rain and snow by switching the low
beams on or off.
The vehicle's external lamps
remain on constantly when you
switch on the front fog lamps after the
headlamps have come on automati-
cally.<
Automatic headlamp control can-
not serve as a substitute for your
personal judgement in determining
when the lamps should be switched on.
For example, the sensors are not able
to detect fog. In such situations switch
on the lamp manually, as otherwise a
safety hazard will result.<
You can have the sensitivity of
your vehicle's automatic head-
lamp control adjusted.<

Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
By repeatedly pressing the button, you
can select one of three different operat-
ing modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – auto-
matic mode: the system detects pol-
lutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air currently within
the vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated-air mode, switch the
recirculated-air mode off and increase
the air supply as required.<
Rear window defroster
With the convertible top closed
or with the hardtop* mounted,
press the button. The indicator lamp
remains on. The rear window defroster
switches off automatically.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
