Loud sound sources outside or inside the car
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 page 112.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure st able 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 pressu re 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 lim its 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cannot be repealed,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 th e responsibility of the
driver. Therefore, do no t 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/activating the DSC OFF
program
The program can be de activated via Dynamic
Driving Control, refer to DSC OFF.
For better control
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
DTC Dynamic Traction Control
The concept
The DTC system and the TRACTION program
is a variant of the DSC in which forward momen-
tum is optimized.
The system ensures maximum forward
momentum on special road conditions, e.g.,
unplowed snowy roads, bu t driving stability is
limited.
It is therefore necessary to drive with appropri-
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
> When driving in slus h or on uncleared,
snow-covered roads.
> When rocking the vehicle or driving off in
deep snow or on loose surfaces.
> When driving with snow chains.
Deactivating/activ ating DTC Dynamic
Traction Control
The system and program can be deactivated/
activated via Dynamic Driving Control.

Head Light
*
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 parkin g lamps if necessary,
switch position 1.
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.
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 ro adside parking lamps,
refer to page 90.<
Low beams
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 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 page 89. In the situations
described above, the la mps then automatically
switch from daytime runn ing lamps to low beams.
The headlamps may also come on when the
sun is sitting low on a blue sky. The automatic headla mp control cannot
serve as a substitute for your personal
judgment in determin ing 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.

Air distribution
Direct the flow of air to the win-
dows , to the upper body area
or to the knee area and footwell
. Intermediate settings are pos-
sible. In the 6 o'clock position, a small amount
of air is also directed towards the windows in
order to keep them from fogging over.
Recirculated-air mode
If the air outside the car has an
unpleasant odor or contains pollut-
ants, shut off the supply to the interior of the car
temporarily. The system then recirculates the
air currently within the vehicle.
You can also activate/d eactivate the recircu-
lated-air mode by means of a button
* on the
steering wheel, refer to page 11.
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
continuously for lengthy periods, otherwise the
quality of the air inside the car will gradually
deteriorate. <
Air flow rate
Press the corresponding button.
The higher the rate, the more

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 th e 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.
