ing
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 one of
the following factors: you are driving under a
speed of 20 mph or 30 km/h, the handbrake is
applied, or DSC is intervening. A message
appears on the Control Display.
Resuming stored desired speed and
distance
Press button 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 control systems are interven-
ing
>In cars with manual transmission: when you
shift gears very slowly or engage neutral
gear
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off
Displays in the instrument cluster
1Stored desired speed
2Shows yellow: vehicle detected ahead
Flashes in red: system cannot maintain dis-
tance; driver must brake the vehicle
Flashes in yellow: driving control systems
are intervening; cruise control is deacti-
vated
3Selected distance to vehicle ahead
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 page74.<
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, however,
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,

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 this. 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
t o u s e p a r t i c ul a r c a r e w h e n r e m o v i n g a n y l a y e r s
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 page73.
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
parked vehicle. Also, the system does not react
to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
a warning to you. Also, be aware that every
decrease in the distance setting allows your
vehicle to come closer to a vehicle in front of you and requires a heightened amount of alert-
ness.<
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's

Technology for driving comfort and safety
78 4.Select "PDC" and press the controller.
5.Select "PDC display on" and press the con-
troller.
6. The PDC screen is activated.
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.<
Keep the sensors clean and free of ice or
snow in order to ensure that they will con-
tinue to operate effectively.
Do not spray the sensors for a long period of
time using high-pressure cleaners and maintain
a distance of at least 4 in/10 cm when spraying
the sensors.<
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 page107.
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 brake application. If the
brake pedal 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.<

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
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 page69:
>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 page72; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<
