2010 BMW 650I CONVERTIBLE cruise control

Driving
70 lane next to you. Always be ready to take action
or apply the brakes if necessary.
In addition, the system is interrupted
whenever the driver applies the vehicle
brakes, shifts the transmission from drive/D to
neutral/N, or deactivates DSC. After any inter-
ruption, the system will no longer automatically
activate the vehicle brakes, which means the
driver must intervene and resume manual brak-
ing. 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.
Unexpected lane change
If a vehicle in front of you is behind a stopped
vehicle and unexpectedly changes lanes, you
must react yourself, as the system does not
react to stopped vehicles.
Swerving vehicles
When a vehicle swerves out of adjacent lanes
into your lane, the system does not detect the
vehicle until it is completely in your lane.
When a vehicle ahead suddenly swerves
into your lane, the system may not be able
to restore the selected distance automatically.
This also applies to great differences in speed
between your vehicle and vehicles ahead, e. g.
when quickly approaching a truck. Once the
system has established that a vehicle is indeed
in front of you, it will indicate that you must
brake and/or maneuver the vehicle yourself.
Take action yourself, otherwise there is a risk of
an accident.<
Behavior in curves
If the selected desired speed for a curve is too
high, the system reduces the speed within a
curve. However, it cannot detect curves in
advance. Therefore, select a suitable speed at
the start of a curve.
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.

Mobility
In approaching a curve, it is possible that active
cruise control might 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
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Driver interventions and your
responsibility
Anytime the driver presses down on the
accelerator pedal, any braking action by
the system is interrupted and the distance indi-
cator goes out until the pedal is fully released.
As soon as you fully release the accelerator, the
system will again control your cruising speed
and distance setting. While driving with the sys-
tem activated, resting your foot on the acceler-
ator pedal will cause the system not to brake
even when necessary. Be certain that floormats
or other objects on the vehicle floor do not inter-
fere with movement of the accelerator pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, e. g.
when you reduce your desired speed sharply. It
uses only a portion of braking system capacity
and does not utilize the full capacity of the vehi-
cle braking system. Therefore, the system can-
not decrease your speed due to large differ-
ences in speed between your vehicle and the
vehicle ahead. Example: when you approach a
vehicle traveling at a much lower speed than
your own speed such as approaching a toll
booth or when a much slower vehicle cuts in
front of you at close range.<

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 provided,
there is a blind spot in which objects can no
longer be detected. The system is also subject
to the physical limits that apply to all forms of
ultrasonic measurement, such as those
encountered with tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e. g. curbs, can
also disappear 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. For this reason,
drive with care; otherwise, there is a danger of
personal injury or property damage.
Loud sources of sound, inside and outside the
vehicle, could drown out 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.
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. For information on safe braking, refer to
page120.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Brake assistant
When you apply the brakes rapidly, this system
produces maximum braking force boosting and
thus helps to achieve the shortest possible
braking distance during full braking maneuvers.
This system exploits all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
Adaptive brake assistant*
In conjunction with the active cruise control
with the stop-and-go function, the adaptive
brake assistant ensures that the brake
responds even more quickly during braking
with the brake assistant.
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 maintain a safe
course within physical limits by reducing engine
output and through braking actions in 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 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 longer

tem can lead to failure or malfunction.
For a system check and to ensure long-term
functioning, you must comply with the mainte-
nance intervals of the service requirements,
refer to page75.<
Head-up Display*
The concept
With the Head-up Display important informa-
tion is projected into the driver's field of view,
e.g. navigation instructions. This enables you to
take in this information without looking away
from the road.

Setting brightness
The brightness of the display is adapted to the
ambient lighting conditions. However, you can
change the base setting.
With the low beams switched on, the brightness
can also be adjusted with the knurled thumb-
wheel of the instrument lighting.
