can drown out the PDC signal. Therefore,
always drive cautiously, otherwise there is a risk
of personal injury or property damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely, refer to page118.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake for the
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system also recognizes unstable
driving conditions, for example if the rear of the
car is about to swerve or if momentum is acting
at an angle past the front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions at the indi-
vidual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving style always remains the responsibility of the
driver. Therefore, do not reduce the additional
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster
light up. Dynamic Traction Control DTC and
DSC have been simultaneously deactivated.
Stabilizing and drive-output promoting actions
are no longer executed.
328i, 335i: in the same way as with a differential
interlock, even if DSC is deactivated, brake
actions are still performed on the rear axle to
enhance drive output if the drive wheels experi-
ence a significant loss of traction.
To increase vehicle stability, activate DSC again
as soon as possible.
Activating DSC
Press the button again; the indicator lamps in
the instrument cluster go out.
For better control
If the indicator lamp flashes:
DSC controls the drive forces and
brake forces.
If the indicator lamps are on:
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions,
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with

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 page52.
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 page55, 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.<

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 page95.<
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 page94. 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
regardless 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.<
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.

automatic air conditioning system is optimized
for driving with the top open. In addition, the air
flow rate is increased as vehicle speed
increases.
The effectiveness of the Convertible pro-
gram can be enhanced considerably by
installing the wind deflector.<
Adjusting air flow rate manually
Press the left side of the button to
reduce airflow. Press the right side
of the button to increase it.
You can reactivate the automatic mode for the
air flow rate with the AUTO button.
The air flow rate may be reduced or the blower
may be switched off entirely to save on battery
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the
left side of the button to switch off the auto-
matic climate control. All displays are cleared
except for the rear window defroster if it is
switched on.
Press any button except REST or rear window
defroster to reactivate the automatic climate
control.
The recirculated-air mode is switched on
when you switch off the automatic cli-
mate control. If the air quality deteriorates or the
window fogs over, switch the system back on
and increase the air volume.<
Automatic recirculated-air control
AUC/Recirculated-air mode
Switch on the desired operating
mode by pressing this button
repeatedly:
>LED off: outside air flows in continuously.
>Left-hand LED on, AUC mode: a sensor
detects pollutants in the outside air. If nec-
essary, the system blocks the supply of out-
side air and recirculates the inside air. As
soon as the concentration of pollutants in
the outside air has decreased sufficiently, the system automatically switches back to
outside air supply.
>Right-hand LED on, recirculated-air mode:
the supply of outside air is permanently
shut off. The system then recirculates the
air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air flow rate as
required.
The recirculated-air mode should not be used
over an extended period of time, otherwise the
air quality inside the car will deteriorate contin-
uously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>Up to 15 minutes after the engine has been
switched off
>While the engine is at operating tempera-
ture
>As long as battery voltage is sufficient
>At an outside temperature below 777/
256
The LED is lit when the function is on.
As of radio readiness, you can set the interior
temperature, the air flow rate and the air distri-
bution.
Defrosting windows and removing
condensation
Quickly removes ice and conden-
sation from the windshield and
front side windows.
Switch on the cooling function as well.
