Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not
recognize this vehicle until it is fully in your lane
ahead of your vehicle.
Malfunction
The indicator lamp lights up and a mes-
sage appears on the Control Display.
The build-up of foreign matter, e. g.,
snow, ice, dirt, road debris, etc., can lead to
reduced detection performance of active cruise
control. You should check the sensor under the
front bumper and clean it as necessary prior to
driving your vehicle. If the sensor becomes cov-
ered by foreign matter or has a malfunction, it is
possible that the sensor will no longer be able to
detect vehicles in front of you. After the system
recognizes that the sensor is no longer func-
tional, a message is displayed on the Control
Display and an acoustic signal is emitted.
When the system does not detect any objects,
e.g. on seldom used roads without a shoulder or
guard rails, the system may temporarily deacti-
vate itself.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Audible signals and an optical display
* indicate
that you are approaching an object in front of or
behind your vehicle. To measure the distance,
there are four ultrasonic sensors in each
bumper. The sensors at the front and at the two
rear corners have a range of approx. 24 in/
60 cm; the rear middle sensors have approx.
5ft/1.50m.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, as
otherwise the physical circumstances would
mean that the system warning was too late.<
Automatic mode
In ignition key position 2, the system automati-
cally assumes operational status after approx.
1 second each time you shift into reverse or
move the selector-lever to position R.
Wait this short period before driving. The sys-
tem switches off when you disengage the
reverse gear.
Manual mode
Press the button; the LED lights up.
Deactivating manual mode
Press the button again; the LED goes out.
The system is automatically deactivated once
the vehicle travels approx. 165 ft/50 m or
exceeds a speed of roughly 20 mph/30 km/h;
the LED goes out. You can reactivate the sys-
tem manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
Thus, an object detected to the left rear of the
vehicle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become shorter.
The signal tone becomes continuous once the
distance to the nearest object falls to below
roughly 1 ft/30 cm.
The warning signal is canceled after approx.
3 seconds if you are moving parallel to a wall.
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
PDC with visual warning*
You also enjoy the option of having the system
show the approach to an object on the Control
Display. The Control Display also indicates the
presence of objects before they are close
enough to trigger a signal tone.
Control Center, for principle details, refer to
page16.

Technology for comfort, convenience and safety
82 Do not reduce the pressure on the brake pedal
for the duration of the brake application. When
the brake pedal is released, DBC is deactivated.
DSC Dynamic Stability Control
The system prevents slip at the drive wheels
when driving off and accelerating. DSC also
detects unstable driving conditions such as
fishtailing or sliding of the front wheels. In these
cases DSC helps the vehicle safely stay on
course within the physical limits by reducing the
engine output and through braking actions in
the individual wheels.
The DSC is operational every time you start the
engine.
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
safety margin again by taking risks.<
DTC Dynamic Traction Control
DTC is a variant of DSC for special road condi-
tions, e.g. uncleared snow-covered roads, that
is optimized for forward momentum. The sys-
tem ensures maximum forward momentum, but
with limited driving stability. Therefore, drive
with the corresponding caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snow-covered uphill
grades, in slushy snow or on uncleared,
snow-covered roads
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button; the DTC indicator lamp in the
instrument cluster lights up.
Deactivating DTC again
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Deactivating DTC and DSC together
Press the button until the DSC indicator lamp in
the instrument cluster lights up, however not
longer than approx. 10 seconds. Interventions
promoting stability and forward momentum will
no longer be carried out. In addition, the stability
promoting intervention of the active steering
*
is deactivated, refer to page85.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To support enhanced operating stability, reacti-
vate DSC again as soon as possible.
Reactivating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.

message appears on the Control Dis-
play. The driving-stability control sys-
tems have failed. Conventional braking
efficiency remains available without
limitations.
While you may continue, you should remember
to proceed cautiously and drive defensively
while avoiding full brake applications.
Have the system checked as soon as possible.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem continuously 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 mes-
sage 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 tendency to tilt
during cornering and in crosswinds.
If a message stating that you should stop
appears on the Control Display, stop and switch
off the engine as soon as possible. In this case
the oil level in the reservoir may have dropped
below the minimum, possibly owing to a leak in
the hydraulic system. Do not continue driving.

Report of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. 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 brak-
ing and steering maneuvers. Do not exceed
a vehicle speed of 50 mph/80 km/h.
If the vehicle is not, as provided at the
factory, equipped with run-flat tires,
refer to page172, stop driving. Continued
driving after a flat tire can result in serious
accidents.<
2.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
3.In case of a complete loss of the tire inflation
pressure or obvious tire damage, you can
estimate the possible driving distance for
continued driving base on the following ref-
erence values:
>With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
>With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
>With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
Drive reservedly and do not exceed
a speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tance and altered natural steering charac-
teristics.
If unusual vibrations occur while the vehicle
is being driven, this can indicate final failure
of the damaged tire. Reduce speed and stop as soon as possible. Do not continue
driving. Contact your BMW center.<
Malfunction
The warning lamp lights up in yellow. A
message appears on the Control Dis-
play. The Flat Tire Monitor has a mal-
function or has failed. Have the system checked
as soon as possible.
Active steering*
The concept
The active steering is a system that actively var-
ies the steering angle of the front wheels in rela-
tion to the steering wheel movements.
A t l o w s p e e d , e . g . i n a t o w n o r w h e n p a r k i n g , t h e
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 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 tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stability-pro-
moting intervention is deactivated when DSC is
switched off, refer to page82.
Malfunction
The warning lamp lights up. The active
steering is no longer operational. At low
speed, larger steering wheel move-
ments are required, while the vehicle reacts
more sensitively to steering wheel movements
in the higher road-speed range. Have the sys-
tem checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.

Initializing system
1.Start the engine.
2.With the vehicle stationary, turn the steer-
ing 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 func-
tions of the active steering will be available once
again.
Brake Force Display
The Brake Force Display lights 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 illuminated area of the rear
brake lamps is enlarged, refer to illustration.
Airbags
The following airbags are located under the
marked covers:
1Front airbags for driver and front passenger
2Coupe: Head airbags
3Front side airbags
4Knee airbag for front passenger
5Knee airbag for driver
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page44. front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of a side impact. The side airbag sup-
ports the side upper body area. The head air
bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents, certain rollover conditions, or rear-end
collisions.
For information on the correct sitting position,
refer to page44.

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 airbag retention
system from the vehicle. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument panel, the
side trim panels on the doors and on the Coupe,
the roof pillars along with the sides of the head-
liner. Do not attempt to remove or dismantle the
steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.
If you note any indication of system malfunc-
tion, if you wish to have an airbag deactivated,
or if the airbag retention system is triggered in
response to an accident, you should always
entrust all inspection, repair and dismantling
operations to your BMW center. Unprofessional
attempts to service the system could lead to
failure in an emergency or undesired airbag
activation, either of which could result in per-
sonal injury.<
Airbag warning information is also provided on
the sun visors.
Operational readiness of airbag system
From ignition key position 1 the warning lamp
lights up briefly, indicating the operational
readiness of the entire airbag system and the
belt tensioners.
Airbag system malfunction
>The warning lamp does not light up as of
ignition key position 1.>The warning lamp lights up continuously.
Have the airbag system checked immedi-
ately if a malfunction occurs, as otherwise
there is a danger of the system not responding
in the expected manner to an impact occurring
within its normal response range.<
Convertible:
Rollover protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal or transverse axis, or loss of ground
contact. The rollover bars located behind the
rear head restraints are deployed within frac-
tions of a second.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion 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 tensioner and
the multistage airbag restraint system.<
Lowering
If the protection function was not required after
automatic activation, the rollover protection
system can be lowered again. No tools are nec-
essary for this purpose.
1.Press the release backward and hold in that
position.

rain or snow, and the Adaptive Head Light
* is
active. The LED next to the symbol is illumi-
nated when the low beams are on.

Lamps
92 The low beams remain on independent of
the ambient lighting conditions when you
switch on the fog lamps.
With the daytime driving lamps activated, the
low beams are always switched on in this switch
position with the ignition key in position 2.<
The automatic headlamp control cannot
serve as a substitute for your personal
