distance setting between your vehicle and the
vehicle ahead. You can vary the distance, which
is also speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically light up to signal
a following driver to take action. In addition, it
may be necessary for the vehicle or the driver to
downshift, depending on the kind of transmis-
sion your vehicle is equipped with, to maintain
the distance setting selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehicle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or with the aid of the driver as needed. Your
selected speed will also be held when driving
downhill, however it can be dropped below
when driving uphill if the engine output is insuf-
ficient.
The minimum desired speed is 20 mph or
30 km/h, and the maximum desired speed
110 mph or 180 km/h.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
which you may be accustomed to, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section begin-
ning on page72.<
Professional* navigation system
If a navigation DVD is in the drive, refer to
page126, the system adjusts the accelerating
and braking behavior of the vehicle to the road
you are driving on.
To ensure that the system is informed of
the current course of the road, always use
the latest navigation DVD if possible. is canceled when the vehicle position is
unknown, e.g. when it has left the mapped
region.
Brake pedal feel
>When the system brakes and you also
depress the brake pedal, a somewhat differ-
ent braking feeling results.
>Any noises produced during automatic
braking are normal.
Manual transmission
You can shift gears with the cruise control acti-
vated. If you drive for extended periods at very
high or very low engine speeds, then a shifting
command is issued or the system is deacti-
vated.
SMG
If you drive for extended periods at very high
engine speeds in Sequential mode, then a shift-
ing command is issued or the system is deacti-
vated.
In the Drive mode, the SMG acts similarly to an
automatic transmission in the D position.

If your vehicle is actively following a vehicle in
front of you and the vehicle ahead speeds up or
the lane ahead becomes clear, then your vehi-
cle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a freeway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a freeway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is activated while driv-
ing, the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts into neutral, or deactivates DSC.
After any deactivation, the system will no longer
automatically activate the vehicle brakes, which
means the driver must intervene and resume
manual braking. You should then reactivate the
system only when you are fully aware of the
prior speed and distance settings.<
Active cruise control may brake when you
reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.
In approaching a curve, it is possible that active
cruise control would react briefly to a vehicle in
the adjacent lane. In addition, the system can
sense if your vehicle is in a curve and may not
accelerate. If your vehicle decelerates in either

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed; otherwise, the physical circumstances
could cause the system warning to be activated
too late.<
Switching on automatically
The system starts to operate approx. 1 second
after you shift into reverse gear or move the
selector lever into position R with the engine
running or the ignition switched on.
Wait this short period before driving.
Switching on manually
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system 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. If
the distance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive 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. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.

You can also enjoy the option of having the sys-
tem show the approach to an object on the
Control Display. Objects that are farther away
are already shown there before a signal tone
sounds. The setting is stored for the remote
control currently in use.

The display appears on the Control Display as
soon as PDC is activated.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstacles always remains with
the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e. g. curbs, can also disap-
pear from the detection area of the sensors
again before or after a continuous tone already
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC signal
tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability under extreme conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during hard braking. This increases active
driving safety.
ABS is operational every time you start the
engine. For information on safe braking, refer to
page121.
CBC Cornering Brake Control
This system provides further enhancements to
vehicle stability and steering response when
braking while cornering or when braking during
a lane change.
Electronic brake-force distribution
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.

Technology for comfort, convenience and safety
88
Brake assistant
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 pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. The system
also identifies unstable driving conditions, such
as a loss of traction at the rear of the vehicle or
sliding of the vehicle in its front wheels. In these
cases, DSC helps the vehicle safely stay on
course within the physical limits by reducing the
engine output and by applying the brakes differ-
ently in the individual 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 restrict the additional
safety margin with a risky driving style, as other-
wise there is a risk of an accident.<
Deactivating DSC
Press the button until the DSC indicator lamp in
the instrument cluster lights up, but not for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated
together. Interventions promoting stability and
forward momentum will no longer be carried
out. The stability-promoting intervention of the
active steering
* is also deactivated, refer to
page94.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.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
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 appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving on snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>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.

Tire Pressure Monitor or Flat Tire Mon-
itor. A message appears on the Control
Display. The driving stability control
systems have failed. Conventional
braking efficiency remains available
without limitations. While you may con-
tinue, you should remember to proceed
cautiously and drive defensively while avoiding
full brake applications. In addition, the Tire
Pressure Monitor or the Flat Tire Monitor has
also failed. Have the system checked as soon as
possible.

Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
operation, the system continuously runs
through closed-loop control cycles lasting only
fractions of a second.
The system assumes operational status each
time you start the engine.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
