safety
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.

Deactivating DTC
Select "DTC" again 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 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.
EDC Electronic Damping
Control*
If the influencing variables such as road surface
quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-
ically adjusts to the new conditions.
iDrive, for principle details, refer to page16.
1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "Vehicle" and press the controller.
4.Select "EDC" and press the controller.

Lamps

Adaptive Head Light*
The concept
Adaptive Head Light is a variable headlamp
control system that enables dynamic illumina-
tion of the road surface. Depending on the
steering angle and other parameters, the light
from the headlamp follows the course of the
road.
Activating Adaptive Head Light
In switch position3, the Adaptive Head Light is
activated and Automatic headlamp control is
switched on.
In order not to blind oncoming traffic, the Adap-
tive Head Light is not active when driving in
reverse and only points toward the passenger
side when the vehicle is stationary.
Malfunction
The LED above the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps
1High beams

3Roadside parking lamps
Roadside parking lamps, left and right*
You also enjoy the option of lighting up just one
side of your vehicle when parking:After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time; otherwise, it may no longer
be possible to start the engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the inside rearview mirror controls this process.
The assistant ensures that the high beams are
switched on whenever the traffic situation
allows. This reduces the strain on you while at
the same time providing you with the best pos-
sible visibility. Of course, you can intervene at
any time and switch the high beams on and off
in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page99.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, whereby the system reacts to oncom-
ing traffic and traffic ahead, as well as to suffi-
cient lighting, e.g. towns/cities.
