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.

88 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 squander your added margin of
safety by driving dangerously; otherwise you
run the risk of causing an accident.<

1.Press the button to open the start
menu.
2.Move the controller toward "Settings".
3.Select "DTC" 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" and press the controller.
The LED on the Control Display and the DSC
indicator lamp on the Info Display go out.
For control purposes

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 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*
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.

Technology for comfort, convenience and safety
90 There are two programs.
With each press of the controller, you can
switch back and forth between "Comfort" and
"Sport".
Comfort program
The Comfort program is suitable for use
throughout the vehicle's entire speed range and
regardless of load.
Sport program
You should select the Sport program for consis-
tently performance-oriented response from
shock absorbers and steering.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirements
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized.>When driving on snow-covered or slippery
road surfaces.
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration.
>When driving with snow chains
*.
Initializing system
The initialization is completed during driv-
ing, which can be interrupted at any time.
The initialization automatically continues when
driving resumes. Do not initialize the system
when driving with snow chains

2.Select "Vehicle" and press the controller.
3.Select "Tires: FTM" and press the control-
ler.
The initialization menu appears.
4.Start the engine, but do not begin to drive.
5.Select "Reset tire pressure" and press the
controller.
During the initialization, "Reset will be com-
pleted while driving. A tire pressure loss
cannot be detected while resetting. Status:
resetting FTM…" appears on the Control
Display.

System limits
TPM cannot warn you of sudden serious
tire damage caused by external influ-
ences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
If a wheel without TPM electronics has been
mounted or if the TPM experiences temporary
interference from other systems or devices that
use the same radio frequency, then the system
is inactive and unable to report a flat tire.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes into account the fact that the tire
pressure changes during driving. A correction is
only required if the color of the TPM display
indicates that it is necessary.
Green
The tire pressure matches the learned set state.
"Status: TPM active" appears on the Control
Display.
One wheel is yellow
There is a flat tire or a major drop in inflation
pressure in the indicated tire. A message
appears on the Control Display.
All wheels are yellow
There is a flat tire or a major drop in inflation
pressure in several tires. A message appears on
the Control Display.
Gray
The system cannot detect a flat tire.
Reasons for this can include:
>TPM is in the process of being reset
>Temporary interference due to systems or
devices that use the same radio frequency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
The reset process is completed during driving
and can be interrupted at any time. When driv-
ing resumes, the process resumes automati-
cally.
