Driving
68 The selected distance is displayed in the instru-
ment cluster.
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.<
Deactivate system
Press the lever up or down. The displays in the
instrument cluster disappear.
You also deactivate the system when you
brake, shift very slowly or into neutral, or
engage the selector lever position N. In addi-
tion, the system is deactivated automatically:
>when you activate the DTC Dynamic Trac-
tion Control
>when you deactivate the DSC Dynamic Sta-
bility Control>When the system does not recognize any
objects for a longer time, e. g. on infre-
quently traveled roads without a shoulder or
guard rails, or if the radar sensor is covered
with dirt, refer to page69
>When the speed is reduced to below
20 mph/30 km/h due to a traffic situation
The system deactivates automatically
when the speed is set to below 20 mph/
30 km/h. A signal sounds and a message
appears in the Control Display. The active inter-
vention of the driver is required, otherwise acci-
dents can occur.<
Resume stored desired speed and
distance
Press button 4.
The displays appear in the instrument cluster.
When you switch off the ignition, the stored
desired speed is deleted.

be that conditions necessary for operation are
not currently being met. To call up Check Con-
trol messages, refer to page77.<
Warning lamps
The display2 flashes red and a sig-
nal sounds.
The system requests that you
intervene by braking or with an
evasive maneuver. The active
cruise control cannot automatically restore the
distance to the vehicle driving ahead.
However, this display cannot relieve the driver
of the responsibility for adjusting the desired
speed and driving style to the traffic conditions.
The display 2 flashes yellow.
Automatic intervention by ABS or
DSC. The active cruise control
intervenes by braking until you
take over actively.
Radar sensor
Heavy rain, dirt, snow or ice can restrict the
detection of vehicles driving ahead. If neces-
sary, clean the front radar sensor under the
bumper. Exercise particular care when remov-
ing 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 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
parked vehicle. Also, the system does not react

Technology for comfort, convenience and safety
84 iDrive, for principle details, refer to page16.
1.Open the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.Select "PDC" and press the controller.
5.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.
The setting is stored for the remote control cur-
rently in use.
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. This applies especially
in those cases where the system approaches
the physical constraints of ultrasonic measure-
ment, as occurs with tow bars and trailer cou-
plings, and in the vicinity of thin or wedge-
shaped objects. Low objects already displayed,
e.g. a curb, can disappear from the detection
area of the sensors again before a continuous
tone sounds. Higher, protruding objects, e.g.
cornices, 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 page117.
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.
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 braking. DBC is switched
off when the brake pedal is released.
DSC Dynamic Stability Control
DSC prevents traction loss in the driving wheels
when starting off and accelerating. DSC also
identifies unstable driving conditions, such as a
loss of traction at the rear of the vehicle or slid-
ing of the vehicle in its front wheels. In these
cases, DSC helps the vehicle maintain a safe
course within physical limits by reducing engine
output and through braking actions in the indi-
vidual wheels.
The DSC is operational every time you start the
engine.

Maintenance
The 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 ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, a complete dealer service history
will prove to be an asset of inestimable value.
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.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page75:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally mandated inspections depending
on local regulations
Service data in remote control
Your vehicle stores this information continu-
ously in the remote control while the vehicle is
being driven. After accessing the data stored in
the remote control, your BMW Service Advisor
can suggest precisely the right array of service
procedures for your own individual vehicle. You
should therefore hand over the remote control
you last used to drive to the BMW Service Advi-
sor when you take your vehicle in for service.
Make sure the date in the iDrive is always
set correctly, refer to page81, otherwise
the effectiveness of CBS Condition Based Ser-
vice is not ensured.<

BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
