Technology for comfort, convenience and safety
78 The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Therefore, do
not reduce the additional safety margin
again by taking risks.<
DBC Dynamic Brake Control
When you apply the brakes rapidly, this
system automatically produces the maxi-
mum braking force boost and thus helps to
achieve the shortest braking distance dur-
ing panic stops. This system exploits all of
the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released,
DBC is deactivated.
Malfunctions of driving stability
control systems
The brake system warning lamp
lights up in red, appearing together
with the indicator lamps for ABS
and DSC. A message appears on
the Control Display. Driving stability
control and ABS have failed. Con-
ventional braking efficiency remains
available without limitations.
While you may continue, you should
remember to proceed cautiously and drive
defensively while avoiding full brake appli-
cations.
Have the system checked as soon as pos-
sible.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll
and optimizes vehicle stability during cor-
nering and evasive maneuvers.
Dynamic stabilizers at the front and rear
axles form the basis for active roll stabiliza-
tion. Suspension compliance adapts to suit
driving conditions, varying from perfor-
mance-oriented during cornering to
smooth and comfort-oriented when the
vehicle is proceeding in a straight line. Dur-
ing vehicle operation, the system continu-
ously runs through closed-loop control
cycles lasting only fractions of a second.
The system assumes operational status
each time you start the engine.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in
the system. Have the system checked as
soon as possible.
If there is a malfunction in the system,
please remember to adapt your
speed accordingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a message stating that you should stop
appears on the Control Display, stop and
switch off the engine as soon as possible.

Report of a flat tire
The warning lamp lights up in red
and a message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat tire
or extensive inflation pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a vehicle speed of 50 mph/
80 km/h
Due to the reinforcement on the
side walls of the run-flat tires,
inflation pressure loss can not usually
be recognized from the outside, refer to
Run-flat tires on page 168.<
2.To continue driving, comply with the
instructions for driving with damaged
tires on page 168.
Malfunction
The warning lamp lights up yellow
and a message appears on the
Control Display. The Flat Tire Moni-
tor has a malfunction or has failed. Have
the system checked as soon as possible.
Active steering*
The concept
The active steering is a system that actively
varies the steering angle of the front wheels
in relation to the steering wheel move-
ments.
When you are driving in the low road speed
range, e.g. in a town or when parking, the
steering angle of the wheels is reinforced,
i.e. the steering becomes very direct.
In the higher speed range, on the other
hand, the steering angle of the wheels is
reduced more and more. This improves the
handling capability of your BMW over the
entire speed range.
In critical situations, the system can make
targeted changes to the steering angle pro-
vided by the driver and thus stabilize the
vehicle before the driver intervenes.
Malfunction
The fixed warning lamp lights up.
The active steering is no longer
operational. In the low speed range,
greater steering wheel movement is neces-
sary. Have the system checked.
If the warning lamp lights up during the first
engine starting following a power supply
interruption, the system must be activated
with initialization.
Initializing system
1.Start the engine
2.With the vehicle stationary, turn the
steering wheel from the straight-ahead
position to the left as far as it will go and
then back to the straight-ahead position
3.Switch off the engine.
When you start the engine again, all the
functions of the active steering are avail-
able once again.
Brake Force Display
The two-stage brake lamps light up in two
stages depending on how strongly you
brake.
>Normal braking:
The brake lamps and the third brake
lamp go on
>Heavy braking and braking with ABS:
In addition, the light area of the rear
brake lamps is enlarged, refer to illus-
tration.

Airbag system operational
The airbag warning lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.<
There is a malfunction in the airbag
system when:
>The warning lamp does not light up as
of ignition key position 1
>The warning lamp remains on continu-
ously
>The warning lamp lights up while the
vehicle is being driven.

Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.<
Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1.Press the release backwards and hold
in that position
2.Press the rollover bar halfway down
from above
3.Let go of the release
4.Press the rollover bar down until it
snaps into place
5.Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.

function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle continuously
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
