Deactivating the rain sensor
Briefly press the button again. The indica-
tor lamp goes out.
The rain sensor is automatically deac-
tivated when you switch off the igni-
tion.<
Deactivate the rain sensor when
passing through an automatic car
wash. Failure to do so could result in dam-
age caused by undesired wiper activa-
tion.<
Selecting wiper fold-out position
Important for changing wiper blades, when
folding away from windshield to prevent
blades from sticking when ice forms, etc.
1.Switch off the engine and remove the
remote control from the ignition lock
2.Press the wiper lever up and maintain
pressure for about 3 seconds until the
wipers are roughly vertical: fold-out
position.
After folding the wipers back against the
windshield you will need to reactivate the
wiper system:
1.Switch on the radio mode
2.Apply brief upward pressure to the
wiper lever. The wipers return to their
retracted position and are ready for nor-
mal operation.
To prevent damage to the wipers,
always fold them back against the
windshield before switching on either the
radio mode or the ignition.<
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks
and open flames, and store it in tightly
closed containers well out of the reach of
children. Always observe the instructions
for use provided on the containers.< We recommend that you mix the
washer fluid before adding it to the
reservoir.<
Windshield and headlamp washer
system
Capacity: 6.3 US quarts/6 liters.
Fill with water and Ð if required Ð with a
washer antifreeze, according to manufac-
turer's recommendations.
Programmable cruise
control
The concept
The programmable cruise control is avail-
able for use at speeds of approx. 20 mph/
30 km/h and higher. The vehicle maintains
and stores the speed that you set using the
lever mounted on the steering column.
You can also use the multilevel preset
mode to store 6 desired speeds for later
selection with the same lever, refer to
page 73.
This feature assists you in quickly adapting
the vehicle speed to specific road condi-
tions, e.g. changes in speeds limits.
Do not use the programmable cruise
control when driving on winding
roads, in heavy traffic or in poor road con-
ditions, e.g. snow, rain, ice, loose road sur-
face, that do not permit a constant speed.<

Swerving vehicles
When a vehicle moves from an adjacent
lane into your lane, active cruise control will
not recognize this vehicle until it is fully in
your lane ahead of your vehicle.
Malfunctions
The build-up of foreign material Ð e.g.,
snow, ice, dirt, road debris, etc. Ð can lead
to reduced detection performance of active
cruise control. You should check the sen-
sor under the front bumper and clean it as
necessary prior to driving your vehicle.
If the sensor becomes covered by foreign
material or has a malfunction, it is possible
that the sensor will no longer be able to
detect vehicles in front of you. After the
system recognizes that the sensor is no
longer functional, a message is displayed
in the Check Control and an acoustic signal
is emitted, refer to page 82. Also observe
the additional information provided in the
Control Center.

PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Signal tones indicate the current distance
to an object behind or in front of your vehi-
cle. Four ultrasonic sensors in both the
bumpers monitor the distance to the near-
est object. The sensors at the front and at
the two rear corners have a range of
approx. 2 ft/60 cm; the rear middle sensors
have 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,
as otherwise the physical circumstances
would mean that the system warning was
too late.<
Automatic function
Whenever the ignition is on the system
automatically assumes operational status
after a few seconds each time you engage
the transmission position R.
Wait this short period before revers-
ing.<
Manual activation
Press the button, the indicator lamp lights
up.
Manual deactivation
Press the button again; the indicator lamp
goes out.
Automatic deactivation
The system is automatically deactivated
once the vehicle travels approx. 165 ft/
50 m or exceeds a speed of roughly
20 mph/30 km/h; the indicator lamp goes
out. You can reactivate the system manu-
ally as needed.
Signal tones
The signal indicating the distance to the
nearest obstacle is directional. Thus, an
object detected to the left rear of the vehi-
cle 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 continu-
ous once the distance to the nearest object
falls to below roughly 1 ft/30 cm.
The warning signal is canceled after
approx. 3 seconds if you are moving paral-
lel to a wall.
Malfunctions
The indicator lamp within the button
flashes and a status message appears in
the Check Control.
Please take note of the additional informa-
tion on the Control Display.
Switch the system off and have the cause
of the malfunction corrected by your BMW
center.

PDC with visual warning
You also enjoy the option of having the sys-
tem show distances to objects on the Con-
trol Display. The Control Display will also
indicate the presence of objects in green
before they are close enough to generate a
signal tone.
Select "PDC pic." from the "Settings" menu
and confirm. This activates the PDC dis-
play.
The display then appears on the Control
Display whenever the PDC is automatically
or manually activated.
The previous display automatically
reappears after the system is deactivated.
Confirming the menu item takes
you back to the previous display.<
Limits of the system
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions 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 ultrasonic measurement,
such as those encountered with tow bars and trailer couplings, as well as thin and
wedge-shaped objects, etc. Low objects
already displayed, e.g. a curb, can also dis-
appear from the detection area of the sen-
sors again before a continuous tone
sounds.
Loud noises from outside and inside the
vehicle may prevent you from hearing
PDC's signal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control/
ABS Antilock Brake System
The concept
ABS enhances active safety by preventing
the wheels from locking under braking.
ABS incorporates CBC and EBV.
In case of malfunction
If the indicator lamp lights up in
yellow, this indicates that ABS has
been deactivated in response to a
system malfunction. Conventional braking
efficiency remains available without limita-
tions. Please have the system inspected at
your BMW center.
CBC Cornering Brake Control
CBC is a supplement to ABS. It provides
further enhancements in vehicle stability
and steering response during lane changes
and cornering at high rates of lateral accel-
eration.
EBV Electronic brake-force
distribution
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.

CBS Condition Based Service
CBS is a more advanced version of the
Service Interval Display. Sensors combine
with highly-specialized algorithms to sup-
ply service information that reflects your
vehicle's actual operating conditions more
precisely than ever before.
The system now furnishes individual dis-
plays of the times remaining until the dead-
lines for specific service operations as well
as official state inspections:
>Engine oil
>Brakes: separate for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs >Vehicle check
>Coolant
>Official state inspections.
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's key, your BMW
Service Advisor is able to suggest precisely
the right array of service procedures for
your own individual vehicle.
By letting you define a service and main-
tenance regimen that reflects your own
individual requirements, Condition Based
Service builds the basis for trouble-free
driving.
You can find more detailed information
on the Service Interval Display on page 81.
