2006 BMW 745Li engine

Driving
74 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
detect 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 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
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with the system activated, resting your
foot on the accelerator pedal will cause the sys-
tem not to brake even if necessary. Be certain
that floormats or other objects on the vehicle
floor do not interfere 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.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: 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.<

with the remaining fuel. It is projected by taking
into account the driving style over the last
20 miles/30 km.
When your cruising range falls below
30 miles/50 km, be sure to refuel. Other-
wise, engine functions are not ensured and
damage can occur.<
Refueling is only registered by the computer for
fuel amounts above approx. 1.3 gallons/5 liters.
Distance to destination
When you enter a destination into the naviga-
tion system or manually enter a distance in the
computer prior to departure, the system can
also display the distance remaining to your des-
tination, refer to page76 or131.
The system automatically applies the distance
to your destination using the route recom-
mended by the navigation system.
When you enter a destination into the
navigation system, any manual entries
will be overwritten once the vehicle has traveled
approx. 1,640 ft/500 m of the calculated dis-
tance.<

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,
four ultrasonic sensors are provided in each
bumper. The range of these sensors is approx.
6 ft/2 m. However, an acoustic warning begins
to sound for the sensors at the front and at the
two rear corners 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
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed; oth-
erwise, the system may sound the warning of
physical obstacles too late.<
Automatically activating
The system starts to operate automatically
approx. 1 second after you engage the trans-
mission position R with the engine running or
the ignition switched on.
Wait this short period before driving.
Manual activation
Press the button, the LED lights up.
Manual deactivation
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 switches
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.
The signal tone becomes continuous once the
distance to the nearest object falls below
roughly 1 ft/30 cm.
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 Info Display. PDC has failed.
Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
PDC with visual warning
You can also have the system show distances
to objects on the Control Display. Objects that
are farther away are displayed there before a
signal tone begins to sound.

System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any objects always remains with the
driver. Even when sensors are involved, there is
a blind spot in which objects cannot be
detected. The system's detection of objects is
also subject to the physical limits that apply to
all forms of ultrasonic measurement, such as
those encountered with tow bars and trailer
couplings, as well as thin and wedge-shaped
objects, etc. It is also possible that low objects
already displayed, such as curb edges, may come into the blind spot of the sensors before a
continuous signal sounds or that the system will
fail to detect higher, projecting obstacles such
as ledges. Loud noises from outside and inside
the vehicle may also prevent you from hearing
the PDC's 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
page123.
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
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
DBC Dynamic Brake Control
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. DSC also

Technology for comfort, convenience and safety
88 detects unstable driving conditions such as
fishtailing or sliding of the vehicle's 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 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. Do not reduce the additional safety mar-
gin by taking unnecessary risks.<
Deactivating DSC
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "DTC" again and press the controller
for at least 3 seconds.
The LED for "DTC" and the DSC indicator lamp
on the Info Display light up. DTC Dynamic Trac-
tion Control and DSC Dynamic Stability Control
are deactivated together. Interventions promot-
ing stability and forward momentum will no
longer be carried out.
To promote enhanced operating stability, reac-
tivate DSC again as soon as possible.
Activating DSC
Select "DTC" again and press the controller.
The LED on the Control Display and the DSC
indicator lamp on the Info Display go out.
For control purposes
If the indicator lamp flashes:
DSC controls the drive forces and
brake forces. The indicator lamp comes on:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a version of DSC that is optimized for
forward momentum in special road conditions.
The system 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 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

Dynamic Drive
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Active stabilizers at the front and rear axles form
the basis for Dynamic Drive. Suspension com-
pliance adapts to suit driving conditions, vary-
ing from performance-oriented during corner-
ing to smooth and comfort-oriented when the
vehicle is traveling in a straight line. During vehi-
cle 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.
Malfunction
The warning lamp lights up yellow and
a message is shown on the Info Display.
A malfunction has occurred in the
Dynamic Drive system. Have the system
checked as soon as possible.
If a malfunction occurs, please remember
to adapt your speed accordingly, espe-
cially 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 Check Control message stating that you
should stop is displayed, stop at a suitable loca-
tion and switch off the engine as soon as possi-
ble. 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, but instead contact
your BMW center.<
Self-leveling suspension*
Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
is shown on the Info Display.
A malfunction has occurred in the level control
system.
Stop driving and check the vehicle:
>The vehicle is considerably lower at the rear
than at the front, possibly also on one side,
at the rear left compared to the rear right.
>The ground clearance is reduced or the
driving comfort is noticeably reduced.
>The position of the vehicle is normal, but a
malfunction is indicated.
Drive to the nearest BMW center or a workshop
that works in accordance with BMW guidelines
and uses appropriately trained personnel. Drive
with appropriate caution in the meantime.
