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
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an object at high speed, oth-
erwise the physical circumstances would mean
that the system warning was too late.<
Automatic activation
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 time before driving off.
Manual activation
Press the button, the LED lights up.
Manual deactivation
Press the button again; the LED goes out.
Automatic deactivation
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
When nearing an object, the position is corre-
spondingly indicated by an interval tone. 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 dis-
tance 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.
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. 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.
Exhaust gases near the rear sensors can cause
a signal tone to sound.

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 optimizes vehicle stability and traction. It
also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin further by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp stays lit: DSC is deactivated.
M Dynamic Mode MDM
The M Dynamic Mode is a mode of the DSC
Dynamic Stability Control. It enables driving
with greater longitudinal and lateral accelera-
tion on dry road surfaces, however with limited
vehicle stability. The system does not provide
stabilizing intervention by reducing the engine
output and braking at the wheels until the abso-
lute driving limit is reached. Additional steering
corrections may also be required in this driving
state.
The M Dynamic Mode is deactivated each time
the engine is started.With the M Dynamic Mode activated, sta-
bilizing interventions are only carried out
to a reduced degree. Take action yourself, oth-
erwise there is a risk of an accident.<
To maintain vehicle stability, drive with
DSC activated and the M Dynamic Mode
deactivated whenever possible.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.
The indicator lamp stays lit: M Dynamic
Mode is activated.
The indicator lamp lights up continuously and
the DSC indicator lamp flashes: the M Dynamic
Mode is active and controls the drive and brak-
ing forces.
Activating MDM
You activate the M Dynamic Mode with the
button on the steering wheel, refer to MDrive on
page50.
With the ignition switched on you can set
MDrive on the Control Display.
iDrive, for operating principle refer to page16.

FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected 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 snowy or slippery road surface
>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 con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains.<
With Sequential Manual Transmission via the
button in the center console:
1.Start the engine, but do not start driving.
2.Press the button for approx. 5 seconds.
After the button is released, the warning
lamp lights up in yellow for several sec-
onds in the instrument cluster, refer to
Indication of a flat tire. The message "Initial-
izing FTM ..." appears on the Control Dis-
play for a few seconds.
3.Start to drive.
The initialization finishes during driving
without feedback.

In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire. To do this, check the
tire inflation pressure using the M Mobility
System, refer to Producing tire inflation
pressure on page219.
3.Repair flat tire with M Mobility System, refer
to page217, or replace the damaged wheel,
refer to Changing wheels on page219.
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset at the correct tire
inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<

Technology for comfort, convenience and safety
86 ing driving. The tires are shown in green on the
Control Display.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.<
Message with low tire inflation
pressure
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
3.Repairing flat tire with M Mobility System,
refer to page217, or replace the damaged
wheel or wheels, refer to Changing wheels*
on page219.
The spare tire
* is equipped with the necessary
TPM electronics and is also monitored after
mounting and after resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheel is mounted without TPM elec-
tronics>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare*, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability. Please note that the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has
not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator lights up, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction

88 or a workshop that works according to BMW
repair procedures with correspondingly trained
personnel and has the required explosives
licenses. Otherwise unprofessional attempts to
service the system could lead to failure in an
emergency or undesired airbag triggering,
either of which could result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbags on the front passenger side are
activated or deactivated accordingly by the sys-
tem.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<
Before transporting a child on the front
passenger seat, observe the safety infor-
mation and handling instructions under Trans-
porting children safely refer to page53.
The front and side airbags on the front passen-
ger side can be deactivated for teenagers and
adults in certain sitting positions; then the indi-
cator lamp for the front passenger airbags lights
up. In these cases, change the sitting position
so that the front passenger airbags are acti-
vated and the indicator lamp goes out. If the
desired status cannot be produced by changing
the sitting position, transport the correspond-
ing person on the rear seat. Do not fit seat cov-
ers, seat cushion padding, ball mats or other
items onto the front passenger seat unless they
are specifically recommended by BMW. Do not
lay objects under the seat which could press
against the seat from below. Otherwise a cor-
rect evaluation of the occupied seat surface
cannot be ensured.<
Operating state of front passenger
airbags
Depending on the vehicle's equipment, the
arrangement of the switches and indicator
lamps may differ somewhat.
The indicator lamp for the front passenger air-
bags indicates the operating status of the front
and side airbags on the front passenger side
depending on the seat occupation. The indica-
tor lamp shows whether the front passenger
airbags are activated or deactivated.
>The indicator lamp lights up when a child in
a child restraint system intended for the
purpose is properly detected on the seat.
The front and side airbags on the front pas-
senger side are not activated.
Most child's seats are detected by the
system. Especially the child's seats
required by the NHTSA at the time the vehicle is
manufactured. After installing a child's seat,
make sure that the indicator lamp for the front
passenger airbags lights up. This indicates that
the child's seat has been detected and the front
passenger airbags are not activated.<
>The indicator lamp does not light up when,
for example, a correctly seated person of
sufficient height is detected on the seat.
The front and side airbags on the front pas-
senger side are activated.
>The indicator lamp does not light up when
the seat is empty.
However, the front and side airbags on the
front passenger side are not activated.
