Driver interventions
Anytime the driver presses down on the
accelerator pedal, any automatic braking
action by the system is interrupted until the
pedal is fully released. After doing this, release
the accelerator and the system again controls
your cruising speed and distance setting. While
driving with activated system, resting your foot
on the accelerator pedal will cause the system
not to brake even if necessary. Be certain that
floormats or other objects on the vehicle floor
do not interfere with movement of the accelera-
tor pedal.<
While active cruise control is capable of
braking your vehicle automatically when
you approach a slower vehicle ahead, it is
important to be aware that the ability of the sys-
tem to apply the brakes is also limited, particu-
larly if you are driving down a steep grade or
when you reduce your desired speed sharply.
The system cannot stop your vehicle. It uses
only a portion of braking system capacity and
does not utilize the full capacity of the vehicle
braking system. Therefore, the system cannot
decrease your speed for large differences in
speed between your vehicle and the vehicle
ahead. Examples: during emergency braking,
when you approach a vehicle traveling at a
much lower speed than your own speed such as
approaching a toll booth or when a much slower
vehicle cuts in front of you at close range.<
Whenever active cruise control
recognizes a situation that requires
driver braking because the system
capacity has been reached or has
been exceeded, the system alerts
the driver by flashing this symbol in the instru-
ment cluster and sounding a signal.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Malfunction
The indicator lamp lights up and a mes-
sage appears on the Control Display.
The build-up of foreign matter, e. g.,
snow, ice, dirt, road debris etc., can lead to
reduced detection performance of active cruise
control. You should check the sensor under the
front bumper and clean it as necessary prior to
driving your vehicle. If the sensor becomes cov-
ered by foreign matter 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 func-
tional, a message is displayed on the Control
Display and an acoustic signal is emitted.
When the system does not recognize any
objects, e.g. on infrequently traveled roads
without a shoulder or guard rails, the system
can automatically deactivate temporarily.

1.Press button.
This opens 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 "Monitor display on" and press the
controller.
The PDC screen is activated.
The display appears on the Control Display as
soon as PDC is activated.
The setting for the remote control currently in
use is stored.
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.The system is also sub-
ject to the physical limits that apply to all forms
of ultrasonic measurement, such as those
encountered with thin and wedge-shaped
objects, etc. Low objects already displayed, e. g. a curb, can also disappear from the detec-
tion area of the sensors again before a continu-
ous tone sounds. Loud noises from outside and
inside your vehicle may prevent you from hear-
ing the PDC signal tone.<
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
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. Safe braking, refer to page107.
CBC Cornering Brake Control
When braking during curves or when braking
during a gear change, driving stability and
steering 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 brake application. When
the brake pedal is released, DBC is deactivated.

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, 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. 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 times or distances of selected main-
tenance intervals and legally mandated dead-
lines, refer to page66:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter
>Brake fluid>Spark plugs
>Vehicle check
>Legally mandated inspections depending
on local regulations
Your vehicle stores this information continu-
ously in the master key while the vehicle is
being driven. After accessing the data stored in
the master key, your BMW Service Advisor can
suggest precisely the right array of service pro-
cedures for your own individual vehicle. You
should therefore hand over to the BMW Service
Advisor the key you last used to drive when you
take your vehicle in for service.
Make sure the date in the Control Center
is always set correctly, refer to page74,
as otherwise the effectiveness of CBS Condi-
tion Based Service is not ensured.<

Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
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
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<
