Driving
72 If the display ACC --- mph/ACC --- km/h
appears briefly in the speedometer, then
conditions required for operation may not cur-
rently be fulfilled. Retrieving Check Control
messages, refer to page81.<
Warning lamps
The display flashes and a chime
sounds.
The system asks you to intervene
by braking or with an evasive
maneuver. The active cruise control cannot
automatically restore the distance to the vehicle
driving ahead.
The display does not relieve you of the respon-
sibility for adapting desired speed and driving
style to traffic conditions.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
actively intervene.
Radar sensor
Heavy rain and also dirt, snow, or ice can limit
the detection of vehicles ahead. If needed,
clean the radar sensor under the front bumper.
When doing so, be particularly careful in remov-
ing layers of snow and ice.
If the sensor is not aligned properly, the active
cruise control cannot be activated.
Things to know about active cruise control
As with conventional cruise control sys-
tems, active cruise control in no way
diminishes or substitutes for the driver's own
personal responsibility, alertness, and aware-
ness in adjusting speed, braking, or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active cruise control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-ramps; during inclement weather such as snow,
strong rain or fog; or when entering inter-
changes, service/parking areas or toll booths.
It is also important to regulate your vehicle's
speed and distance setting within applicable
legal limits. Always be ready to take action or
apply the brakes if necessary, especially when
the system is actively following a vehicle in front
of you.<
Always remember that the range and abil-
ity of the system do have physical limita-
tions. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead

Technology for comfort, convenience and
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 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.

System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any objects always remains with the
driver. Even when sensors are involved, there is
a blind spot in which objects cannot be
detected. The system's detection of objects is
also subject to the physical limits that apply to
all forms of ultrasonic measurement, such as
those encountered with tow bars and trailer
couplings, as well as thin or wedge-shaped
objects. Low objects already indicated, such as
curb edges, may enter the blind spot of the sen-
sors before or after a continuous audible signal is given. Higher, protruding objects, such as
wall ledges, may not be detectable.
Loud noises from outside and inside the vehicle
may also prevent you from hearing the PDC's
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
page123.
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
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
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 detects unstable driving conditions such

* and Adaptive Head Light*
If you open the driver's door when the ignition is
switched off, then the exterior lighting is
switched off if the light switch is in position0, 2
or3.
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 left-hand or right-hand roadside
parking lamps, refer to page101.<
Low beams
The low beams light up when the light switch is
in position 2 and the ignition is on.
Automatic headlamp control
In the switch position3, the system activates
the low beams and switches them on or off in
response to changes in ambient light condi-
tions, for example in a tunnel, at dawn and dusk,
and in case of precipitation. The LED next to the symbol is illuminated when the low beams are
on.
The low beams may be switched on when the
sun is low on the horizon in a clear sky.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps.<
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 or hazy weather. To avoid
safety risks, you should always switch on the
lamps manually under these conditions.<
Pathway lighting
After parking the vehicle and switching off the
headlamps, you can use the headlamp flasher
control to activate the low beams for a period of
roughly 40 seconds.
Pressing the button on the remote control,
refer to page32, also switches on the low
beams for approx. 40 seconds. In addition, the
door handle and interior lamps are switched on
for approx. 10 seconds.
Daytime running lamps*
The daytime running lamps light up in posi-
tion0, 1 or3. The light output is lower than with
the low-beam headlamps.
If the light switch remains in position1, then the
parking lamps are lit after the ignition is
switched off.
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

A congenial climate
For almost all conditions, the AUTO program1
offers the optimal air distribution and air vol-
ume. Select an interior temperature that you
find pleasant.
The following section contains more detailed
information on the available setting options.
The settings are stored for the remote key cur-
rently in use.
AUTO program
The AUTO program handles the
adjustment of air distribution to the
windshield and side windows, in
the direction of the upper body, and in the foot-
well, as well as the adjustment of the air volume. It also adapts your instructions for the tempera-
ture to outside influences throughout the year.
The cooling is switched on automatically with
the AUTO program. At the same time, a con-
densation sensor controls the program so as to
prevent window condensation as much as pos-
sible.
Intensity of AUTO program
You can adjust the intensity of the AUTO pro-
gram by repeatedly pressing the AUTO button.
Press the button to have the current setting
briefly displayed on the lower status line of the

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:
>LEDs off: outside air flows into the vehicle
continuously.
>Left LED on, AUC mode: the system
detects pollutants in the outside air and
responds by blocking the supply of outside
air when required.
>Right LED on, recirculated-air mode: the
supply of outside air into the vehicle is con-
tinuously blocked.If the windows fog over in recirculated-air
mode, then press the AUTO button or
switch off the recirculated-air mode and
increase the air quantity as needed.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Automatic climate control, switching
on and off
The air volume, the heater, and the
air conditioner mode are all
switched off.
You can restart the automatic climate control by
pressing any of its buttons except the REST
button.
Temperature adjustment
Adjust the desired temperature
individually on the driver's side and
passenger side. Your settings
appear on the status line of the
Control Display.
The automatic climate control achieves this
temperature as quickly as possible at any time
of year, if necessary with the maximum cooling
or heating capacity, and then keeps it constant.
When switching between different tem-
perature settings in rapid succession, the
automatic climate control does not have suffi-
cient time to achieve the set temperature.<
The highest setting switches on the maximum
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air
conditioning.

Maximally cooled air is obtained as
quickly as possible at an outside
temperature of 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 quantity only flows out of the vents
for the upper body. So open these vents for

Residual heat
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off, e.g.
while the vehicle is 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

BMW Maintenance System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes oper-
ations related to the vehicle's comfort and con-
venience features, such as replacement of the
filters for the inside air. The aim is to optimize
maintenance procedures with a view to reduc-
ing the cost of running the vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. As a result, Condition Based Service
determines the current and future maintenance
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system forms
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times and distances for selected
maintenance procedures and any legally man-
dated deadlines displayed, refer to page78:
>Engine oil
>Brakes, separate for front and rear
>Microfilter
>Brake fluid
>Spark plugs>Vehicle check
>Legally prescribed inspections depending
on national regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. After accessing the data
stored in the vehicle key, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. This is why it is important when you take
your vehicle in for service to give the BMW Ser-
vice Advisor the last remote control you used
for driving.
Storage periods with the battery discon-
nected are not taken into account by the
CBS maintenance system. If this occurs, have a
BMW center update the time-dependent main-
tenance procedures, such as checking brake
fluid and if necessary engine oil and the micro/
activated charcoal filter.<
