resistance.
To prevent possible damage to the
rear brakes, always make sure that
the parking brake is completely released
before driving the vehicle.<
5.Return the tools to their places.
6.Return the spare tire cover and the floor mat
to their original locations.
Have a malfunction corrected only by a
BMW center or a repair shop that works in
accordance with BMW guidelines and uses
appropriately trained personnel. Only techni-
cians can return the parking brake to normal
operational status after it has been released
manually in response to a malfunction.<
Following manual release, the actual sta-
tus of the parking brake may deviate from
that displayed by the indicator lamp.<
Reinitializing after a power supply
interruption
The parking brake can only be used again
if it was manually released due to an inter-
ruption in the supply of electrical power. Other-
wise, the function of the parking brake is not
guaranteed and there is a danger of the vehicle
rolling despite the parking brake being
engaged.<
Once the electrical power supply has been
restored, you can again use the parking brake:
With the ignition on and the vehicle
stationary, briefly press the button
three times at intervals of approx.
5 seconds. This executes the fol-
lowing initialization sequence:

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 is activated approx. 1 second after
you engage the transmission position R with
the engine running or the ignition switched on.
Wait this short period before proceeding.
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.
iDrive, for principle details, refer to page16.

Deactivating DTC
Select "DTC" and press the controller.
The LED on the Control Display and the DTC
indicator lamp on the Info Display go out.
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 appears 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 indicates an oil loss,
stop as soon as possible at a suitable location
and switch off the engine. Do not continue driv-
ing, contact your BMW center.
Self-leveling suspension*
Malfunction
The warning lamp for self-leveling sus-
pension lights up yellow and a message
appears 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.
EDC Electronic Damping
Control*

quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-
ically adjusts to the new conditions.
