safety
PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners 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 the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed; otherwise, the physical circumstances
could cause the system warning to be activated
too late.<
Switching on automatically
The system starts to operate approx. 1 second
after you shift into reverse gear or move the
selector lever into position R with the engine
running or the ignition switched on.
Wait this short period before driving.
Switching on manually
Press the button; the LED lights up.
Switching off manually
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 is
switched 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. If
the distance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
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 Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.

PDC with visual warning*
You can also enjoy the option of having the sys-
tem show the approach to an object on the
Control Display. Objects that are farther away
are already shown there before a signal tone
sounds. The setting is stored for the remote
control currently in use.
iDrive, for explanation of principle, refer to
page16.

troller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
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 involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects etc. Low objects
already displayed, e. g. curbs, can also disap-
pear 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.
Loud noises from outside and inside the vehicle
may prevent you from hearing 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.
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
page121.
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
This system controls the brake system's appli-
cation pressure at the rear wheels to ensure
stable deceleration.

Technology for comfort, convenience and safety
88
Brake assistant
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. 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 safely stay on
course within the physical limits by reducing the
engine output and by applying the brakes differ-
ently 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. 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 for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated
together. Interventions promoting stability and
forward momentum will no longer be carried
out. The stability-promoting intervention of the
active steering
* is also deactivated, refer to
page94.A message appears on the Control Display.
Please note any supplementary information
that appears there.
To support enhanced operating stability, reacti-
vate DSC again as soon as possible.
Activating DSC
Press the button; the indicator lamp in the
instrument cluster goes out.
For better control
The indicator lamp flashes:
DSC is controlling the drive forces and
brake forces.
The indicator lamp lights up:
DSC is deactivated.
DTC Dynamic Traction Control
DTC is a variant of DSC for special road condi-
tions, e.g. uncleared snow-covered roads, that
is optimized for forward momentum. The sys-
tem 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 snowy inclines, in slush, or
on unplowed, snow-covered road surfaces
>When rocking a stuck vehicle free or when
starting off in deep snow or on loose ground
>When driving with snow chains
*
Activating DTC
Press the button; the DTC indicator lamp in the
instrument cluster lights up.

Malfunction in driving stability control
systems
The warning lamp for the brake system
lights up, together with the Indicator
and warning lamps for ABS, DSC and
Tire Pressure Monitor or Flat Tire Mon-
itor. A message appears on the Control
Display. The driving stability control
systems have failed. Conventional
braking efficiency remains available
without limitations. While you may con-
tinue, you should remember to proceed
cautiously and drive defensively while avoiding
full brake applications. In addition, the Tire
Pressure Monitor or the Flat Tire Monitor has
also failed. Have the system checked as soon as
possible.

Dynamic Drive*
The concept
Dynamic Drive minimizes body roll and opti-
mizes vehicle stability during cornering and
evasive maneuvers.
Dynamic Drive is based on active stabilizers on
the front and rear axles. Suspension compli-
ance adapts to suit driving conditions, varying
from performance-oriented during cornering to
smooth and comfort-oriented when the vehicle
is proceeding in a straight line. During vehicle
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.
FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.

Technology for comfort, convenience and safety
90 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:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid severe brak-
ing and steering maneuvers and do not
exceed a speed of 50 mph/80 km/h.
Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was
when it came from the factory, refer to
page204. Continued driving after a flat tire
can result in serious accidents.<

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking.
The parking lamps drain the battery. Do
not leave them switched on for long peri-
ods of time, otherwise it may no longer be pos-
sible to start the engine. It is preferable to
switch on the roadside parking lamps on one
side, refer to page104.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
If the light switch remains in position 2, the
exterior lamps are switched off automatically
when the driver's door is opened while the igni-
tion is off.
Switch on the parking lamps if required as
described under Parking lamps.
Automatic headlamp control
In switch position3, the system activates the
low beams and switches them on or off in
response to changes in ambient light condi-
tions, for instance, in a tunnel, at dawn and dusk
and in case of precipitation. Adaptive Head
Light
* is active. The LED next to the symbol is
illuminated when the low beams are on.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain on independent of
the ambient lighting conditions when you
switch on the fog lamps.<
If desired, the light switch can be left in posi-
tion3. The exterior lighting is automatically
switched off after switching off the vehicle.
The automatic headlamp control cannot
serve as a substitute for your personal
judgment in determining when the lamps
should be switched on in response to ambient
lighting conditions. For example, the sensors
cannot detect fog of hazy weather. To avoid
safety risks, you should always switch on the
low beams manually under these conditions.<
Pathway lighting
When you activate the headlamp flasher after
parking the vehicle and switching off the lamps,
the low beams will come on for a brief period.
You can set the duration or deactivate the func-
tion via iDrive.

compartment can only be cooled with the
engine running.
Maximum cooling
Maximally cooled air is obtained as
quickly as possible from an outside
temperature above approx. 327/
06 and with the engine running.
The automatic climate control changes over to
the lowest temperature and switches into the
recirculated-air mode. The maximum air vol-
ume only flows out of the vents for the upper
body. It is therefore necessary for these vents to
be open for maximum cooling.
AUC Automatic recirculated-air
control/recirculated-air mode
You can respond to unpleasant
odors or pollutants in the immedi-
ate environment by temporarily
suspending the supply of outside air. The sys-
tem then recirculates the air currently within the
vehicle. In AUC mode, a sensor detects pollut-
ants in the outside air and controls the shut-off
automatically.
Press the button repeatedly to run through the
following control sequence:
>LED off: outside air flows into the vehicle
continuously.
>Right LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Left LED on, recirculated-air mode: the
supply of outside air into the vehicle is shut
off continuously.
If condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing the air volume as
required.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Residual heat
The heat stored in the engine is
used to heat the passenger com-
partment, e.g. while stopped at a
school to pick up a child.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine
>engine at operating temperature
>sufficient battery voltage
>outside temperature below 777/256
The LED lights up when the function is
switched on.
With the ignition lock at radio readiness or
higher the interior temperature, the air volume
and the air distribution can be set.
