Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic o r in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi-
cle and cause an accident.<

Maintaining speed, storing speed,
and accelerating
Press lever to resistance point, arrow 1:
The speed currently being driven is maintained
and stored. The display1 in the speedometer,
see below, indicates this regulated speed.
Every time you press the lever, the vehicle's
speed increases by roughly 1 mph/1 km/h.
Press lever to resistance point for a longer time:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.Press the lever beyond the resistance point:
Increase speed each time to the next fives place
on the mph speedometer or to the next tens
place on the km/h speedometer.
If, on a downhill grade, the engine's braking
effect is not sufficient, the controlled speed can
be exceeded. Speed can drop on uphill grades if
the engine output is insufficient.
Maintaining speed, storing speed, and
decelerating
Pull the lever, arrow2:
Functions are the same as1, only the vehicle
speed is reduced.
Interrupting cruise control
Press the lever up or down, arrow3.
In addition, cruise control is automatically deac-
tivated:
>When the brakes are applied
>For manual shifting with the shift paddles or
the selector lever
>When the DSC comes on
Resuming stored speed
Press button4:
The stored speed is resumed and maintained.
Deactivating system
When the ignition is switched off, the system is
deactivated and the stored speed is deleted.

the engine temperature. As the engine temper-
ature rises, the permissible engine speed also
increases. Avoid allowing the engine speed to
rise as far as the orange warning field whenever
possible.
Be sure to avoid engine speeds in the red warn-
ing field. In this range, the fuel supply is inter-
rupted to protect the engine.

The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 gallons/
70 liters. You will find information on refueling
on page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.

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 automatically
approx. 1 second after you select 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.
Manual activation
Press 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 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.

5.Change to upper field if necessary. Turn the
controller until "PDC" is selected and press
the controller.
6.Select "PDC display on" and press the con-
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 obstructions always remains
with the driver. Even when sensors are pro-
vided, there is a blind spot in which objects can
no longer be detected. The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with tow bars and trailer cou-
plings, or thin and wedge-shaped objects etc.
Low objects already displayed, e. g. curbs, can
also disappear 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 sources of sound, inside and outside the
vehicle, could drown out 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 locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
The ABS is operational every time you start the
engine. Braking safely refer to page113.
CBC Cornering Brake Control
When braking during curves or when braking
during a lane change, driving stability and steer-
ing response are improved further.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.

Technology for comfort, convenience and safety
80
DBC Dynamic Brake Control
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. Steering correc-
tions by the driver 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.<
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 indica-
tor 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 change
the settings of MDrive on the Control Display.
iDrive, for explanation of principle, refer to
page16.

EDC Electronic Damping
Control
The concept
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 within a
fraction of a second.
You can choose from three programs.
"Comfort" program
Select the "Comfort" program if you want com-
fort-oriented coordination of shock absorbers
and steering.
"Normal" program
The "Normal" program offers a balanced mix-
ture of the comfort and the sport program.
"Sport" program
Select the "Sport" program if you want a con-
sistently sporty coordination of shock absorb-
ers and steering.
Selecting program
With a manual transmission the EDC button is
located in front of the gearshift lever.
Press the EDC button repeatedly:
>"Comfort": LED off.
>"Normal": one LED lights up.
>"Sport": both LEDs light up.
The last selected program is active each time
the engine is started.
You can also activate your preferred program
with the button on the steering wheel, refer
to MDrive on page50.
Flat Tire Monitor FTM*
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 is
reported 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.
