Deactivating cruise control
Press the lever upward or downward, arrow3.
The displays on 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 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 page71
>When you apply the parking brake
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 30 km/h, an application
of the parking brake or a DSC intervention. A
message 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 ma nua l trans mis sio n: when you
shift gears very slowly or shift to idle posi-
tion
>In cars with automatic transmission: when
you engage selector lever position N
>When the ignition is switched off

are currently not met. Calling up Check Control
messages, refer to page84.<
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 deactivated. You can reactivate the system, if
desired, by tapping or pulling the lever when
road and traffic conditions permit. It is not pos-
sible 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 page83.
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.<

until "PDC" is selected and press the con-
troller.
6.Select "PDC display on" and press the con-
troller.
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 hitches,
thin or wedge-shaped objects, etc. Low objects
that have already been displayed, e. g. curbs,
can disappear again from the detection area of
the sensors before or after a continuous tone
sounds. Higher, protruding objects, e.g. ledges,
cannot be detected. Loud sound sources out-
side 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 page125.
EBV 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 full braking application.
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, as this could
result in an accident.<

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance 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 page79:
>Engine oil
>Brake pads: separately for front and rear
>Brake fluid
>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 page82; otherwise the
effectiveness of Condition Based Service CBS
is not assured.<

for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.

cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide

fied regular maintenance.<
