Deactivating intermittent wipe or rain
sensor
Press button 3 again. The LED goes out.
Deactivate the rain sensor before enter-
ing an automatic car wash. Failure to do
so could result in damage caused by undesired
wiper activation.<
Cleaning windshield and headlamps*
Pull lever 4.
Washer fluid is sprayed onto the windshield and
the wipers are operated for a short time.
When the vehicle lighting system is switched
on, the headlamps are cleaned at regular and
appropriate intervals.
Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers when the washer fluid
reservoir is empty, otherwise you will damage
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
automatically while the engine is running or the
ignition switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in the tightly closed
original container, well out of the reach of chil-
dren. Comply with the instructions on the con-
tainer.<
Washer fluid reservoir
Fill with water and, if required, with a washer
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling
the washer fluid reservoir to make sure
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving
conditions are unfavorable for driving at a
constant speed. Otherwise you could lose con-
trol of the vehicle and cause an accident as a
result. Unfavorable driving conditions include,
for example, winding roads, heavy traffic or a

Use good judgement to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, you may be in violation of the law or
an accident could result.<
Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays in the speedometer disappear.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When the speed is reduced to below
20 mph or 30 km/h due to a traffic situation
>When you switch gears very slowly or shift
to idle in cars with manual transmission
>When you select the automatic transmis-
sion's/SMG's neutral position N
>When you activate the Dynamic Traction
Control DTC
>When you deactivate the Dynamic Stability
Control DSC
>When DSC or ABS is intervening
>When the system does not recognize any
objects for a longer period of time, e.g. on infrequently traveled roads without a shoul-
der or guard rails, or if the radar sensor is
covered with dirt, refer to page66
>When you apply the handbrake
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary, otherwise there is a
risk of accident.<
Warning lamp
The warning lamp comes on when
active cruise control has been auto-
matically deactivated due to a driving
speed below 20 mph or 30km/h, an application
of the handbrake or a DSC intervention. A mes-
sage appears on the Control Display.
Resuming stored desired speed and
distance
Briefly press the button, arrow 4.
The stored speed and distance are regained
and maintained.
In the following instances, the stored speed is
deleted and can no longer be resumed:
>When driving stability control systems are
intervening
>In cars with manual transmission: when you
shift gears very slowly or shift to idle posi-
tion
>With automatic transmission/SMG: when
you engage selector lever position N
>When the ignition is switched off

tance; driver must brake the vehicle
Flashes in yellow: driving stability control
systems are intervening; cruise control is
deactivated

The indicator lights up as soon as the sys-
tem is activated.
4Selected desired speed is temporarily dis-
played
If --- mph or --- km/h temporarily appears
in the instrument cluster display, it is pos-
sible that the system prerequisites for operation
are currently not met. Calling up Check Control
messages, refer to page80.<
Warning lamps
The indicator2 flashes in red; a
signal sounds.
The system indicates that you
must brake and/or maneuver the
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to
the vehicle ahead.
This indicator does not release you from your
responsibility to adapt your desired speed and
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow.
The prerequisites for operating
active cruise control are not met,
e.g. as a result of ABS or DSC interventions. Active cruise control is deacti-
vated. You can reactivate the system, if desired,
by tapping or pulling the lever when road and
traffic conditions permit. It is not possible to
resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bumper, see arrow. Be sure
to use particular care when removing any layers
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page79.
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a

Technology for driving comfort and safety
84 1.Open the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "PDC" is selected and press the con-
troller.
5.Select "PDC display on" and press the con-
troller.
6. The PDC screen is activated.
The setting is stored for the remote control cur-
rently in use.
The display is shown on the Control Display as
soon as PDC is activated.
System limitations
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 trailer towbars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as a curb, may
enter the sensors' dead areas before a continu-
ous audible signal is given. Higher, protruding
objects, such as ledges, may not be detectable.
Loud sound sources outside or inside the car
can drown out the PDC signal.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving 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 page117.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure 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 for the
duration of the brake application. If the brake is
released, DBC will be switched off.
DSC Dynamic Stability Control
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. DSC also recognizes unstable driving
conditions, for example if the rear of the car is
about to swerve or if momentum is acting at an
angle past the front wheels. In these cases,
DSC helps the vehicle maintain a safe course
within physical limits by reducing engine output
and through braking actions at the individual
wheels.
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 again by taking risks.<

BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air. The
objective is to optimize efforts with respect to
minimal vehicle maintenance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times or distances for selected main-
tenance tasks and any legally prescribed dates
displayed, refer to page74:
>Engine oil
>Brakes: separately for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid
>Spark plugs
>Vehicle check>Legally mandated inspections depending
on local regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this data from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page78; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<
