rently in use.
To exit the menu:
Select the arrow and press the controller.
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 and wedge-shaped
objects, etc. It is also possible that low objects
already displayed, such as curb edges, may come into the blind spot of the sensors before a
continuous signal sounds or that the system will
fail to detect higher, projecting obstacles such
as ledges. 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.
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 prevents traction loss in the driving wheels
when starting off and accelerating. DSC also

Parking lamps
In switch position1, the front, rear and side
vehicle lighting is switched on. You can use the
parking lamps for parking. For lighting on one
side for parking as an additional feature, refer to
page100.
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.<
Low beams
The low beams light up in switch position2 only
with the engine running. Otherwise, the parking
lamps are lit.
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.When driving into a tunnel with bright overhead
lighting, switching on of the lights may be
delayed.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams remain switched on
regardless of the ambient light when you
switch on the front fog lamps.
When daytime running lamps are activated, the
low beams are always switched into switch
position3 whenever the ignition is switched
on.<
If so desired, the light switch can be left in the
position3. 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
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 page33, 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*
If so desired, the light switch can remain in
position2 or 3.
The exterior lighting is automatically switched
off after switching off the vehicle.
Switch on the parking lamps if required as
described under Parking lamps.

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
from the headlamp follows the course of the
road.
Activating Adaptive Head Light
In switch position3, the Adaptive Head Light is
activated and Automatic headlamp control is
switched on.
In order not to blind oncoming traffic, the Adap-
tive Head Light is not active when driving in
reverse and only points toward the passenger
side when the vehicle is stationary.
Malfunction
The LED above the symbol for automatic head-
lamp control flashes. Adaptive Head Light is
malfunctioning or has failed. Have the system
checked as soon as possible.
High beams/
roadside parking lamps
1High beams
2Headlamp flasher
3Roadside parking lamps
Roadside parking lamps, left and right*
You also enjoy the option of lighting up just one
side of your vehicle when parking:After parking the vehicle, press the lever in the
desired direction3, past the resistance point.
The roadside parking lamps drain the bat-
tery. Do not leave them switched on for
long periods of time; otherwise, it may no longer
be possible to start the engine.<
High-beam assistant*
The concept
This system automatically switches the high
beams on and off again. A sensor on the front of
the inside rearview mirror controls this process.
The assistant ensures that the high beams are
switched on whenever the traffic situation
allows. This reduces the strain on you while at
the same time providing you with the best pos-
sible visibility. Of course, you can intervene at
any time and switch the high beams on and off
in the accustomed manner.
Activating high-beam assistant
1.Turn the light switch to switch position3,
refer to page99.
2.Press the turn signal lever in the high beam
direction with the low beams switched on.
The indicator lamp in the instrument
cluster lights up when the high-beam
assistant is activated. The assistant
automatically switches between high and low
beams, whereby the system reacts to oncom-
ing traffic and traffic ahead, as well as to suffi-
cient lighting, e.g. towns/cities.

Manually switching between high and
low beams
You can intervene at any time you wish or the
situation requires.
>If the high-beam assistant has switched on
the high beams, but you want to use the low
beams, simply switch to the low beams with
the turn signal lever. The high-beam assis-
tant is deactivated in the process.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>If the high-beam assistant has switched on
the low beams, but you want to use the high
beams, switch to the high beams in the
accustomed manner. The system is deacti-
vated in the process and you must switch to
the low beams manually.
To reactivate the system, briefly press the
turn signal lever in the high beam direction
again.
>You use the headlamp flasher as usual with
low beams.
System limits
The high-beam assistant cannot replace
personal decisions on the benefits of
using the high beams. In situations which
require this, you should therefore switch to the
low beams manually to avoid a safety risk.<
In the following example situations, the system
either does not operate or only operates to a
limited degree and a personal reaction may be
required:
>Under extremely unfavorable weather con-
ditions, such as heavy fog or precipitation.
>For perceiving road users with poor lighting
of their own, e.g. pedestrians, cyclists, peo-
ple on horseback, horse-drawn vehicles,
with train or ship traffic close to the road and
wild animals crossing the road.
>In tight curves, on steep crowns or depres-
sions, with cross traffic or partially con-
cealed oncoming traffic on the freeway.
>In poorly lit places and with highly reflective
signs.>In the low speed range.
>When the windshield is dirty or covered with
stickers, decals etc. in the area of the inside
rearview mirror.
>When the sensor is dirty. Clean the sensor
on the front side of the inside rearview mir-
ror with a cloth moistened with a small
amount of glass cleaner.
Fog lamps
Briefly press the button to switch on/off.
Front fog lamps
The parking lamps or low beams must be
switched on for the fog lamps to operate. The
green indicator lamp on the Info Display lights
up whenever the fog lamps are on.
If the automatic headlamp control is acti-
vated, the low beams will come on auto-
matically when you switch on the fog lamps.<
Instrument lighting
You can adjust the lighting intensity with the
knurled wheel.

A congenial climate
For almost all conditions, the AUTO program1
offers the optimal air distribution and air vol-
ume. Select an interior temperature 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.
If you briefly press the button, the current set-
ting is displayed in 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 condensation starts to form on the
inside window surfaces during operation
in the recirculated-air mode, you should switch
it off while also increasing air supply as
required. Make sure that air can flow to the
windshield, e.g. by pressing the AUTO button.
The recirculated-air mode should not be used
over a longer period of time, as the air quality
inside the vehicle deteriorates continuously.<
Switching off automatic climate control
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
You can turn to select the desired
temperatures for the driver's and
passenger sides. Your settings
appear on the status line of the
Control Display. The number
shown in the display provides a general indica-
tion of interior temperature.
The automatic climate control adjusts this tem-
perature 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.<
Using iDrive
1.Open the start menu.
2.Open "Climate".
3.Turn the controller to select driver's side or
passenger side.
4.Turn the controller to select the field and

Maximum cooling
Maximally cooled air is obtained as
quickly as possible from an outside
temperature above 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
maximum cooling.
Air volume
You can vary the air volume by
turning. You can reactivate the
automatic air supply mode by
pressing the AUTO button.
Manual air distribution

when you notice condensation on windows and
want to use the advantages of the condensation
sensor.
Defrosting windows and removing
condensation
Quickly remove ice and condensa-
tion from the windshield and front
side windows.
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
railroad crossing.
The function can be switched on when the fol-
lowing conditions are met:
>up to 15 minutes after switching off the
engine

Maintenance
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.
You can have the remaining times or distances
to selected maintenance requirements as well
as legally required deadlines displayed on the
Control Display, 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
Your vehicle stores this information continu-
ously in the ignition key while the vehicle is
being driven. After accessing the data stored in
the vehicle key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. This is
why it is important when you take your vehicle in
for service to give the BMW Service 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. Have the time-
dependent service and maintenance opera-
tions, such as brake fluid and coolant, and if
necessary engine oil and the micro/activated
charcoal filter, updated by a BMW center.<
