Check Control
The concept
The Check Control monitors vehicle functions
and alerts you to any malfunctions in the sys-
tems monitored. A Check Control message
encompasses indicator and warning lamps in
the instrument cluster and may include an
acoustic signal and text messages on the Con-
trol Display.
Indicator and warning lamps
Indicator and warning lamps can light up in a
variety of combinations and colors. indicates that Check Control messages have
been stored. You can view the Check Control
messages whenever it is convenient for you.
Explanatory text messages
Text messages at the upper edge of the Control
Display explain the meaning of the displayed
indicator and warning lamps.
For most Check Control messages, you can
view more information later, e.g., regarding the
cause of a malfunction and how to respond;
refer to the information provided below.
In urgent cases, this information will be shown
as soon as the corresponding lamp comes on.
To exit the displayed information:
Move the controller to the left.

Some Check Control messages are displayed
until the malfunctions have been rectified. They
cannot be hidden. If several malfunctions occur
at the same time, they are displayed in suc-
cession.
They are marked with the symbol
shown here.
Other messages are automatically hidden after
approx. 20 seconds, but are kept in memory.

Speed limit
You can enter a speed, and a Check Control
message will indicate when you reach this
speed. This enables you, for example, to
receive warnings if you exceed a speed limit in
an urban area.
You are not alerted to having reached this
speed again until after your vehicle speed drops
below it by at least 3 mph or 5 km/h.

Volume of the warning signals*
You can raise or lower the volume of the warn-
ing signals, e.g., the 'Fasten safety belts'
reminder, relative to the entertainment sound
output. The warning signals have a fixed mini-
mum and maximum volume that cannot be
dropped below or exceeded.

Technology for driving comfort and safety
Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight
parking spaces. Acoustic signals and a visual
indicator
warn you of the presence of an object
in front of
* or behind your vehicle. To measure
the distance, there are four ultrasonic sensors
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not
sound until an object is approx. 24 in/60 cm
from the corner sensors, or approx. 5 ft/1.50 m
from the center sensors.
PDC is a parking aid that can indicate
objects when they are approached
slowly, as is usually the case when parking.
Avoid approaching an objec t a t h i g h s p e e d ; o t h -
erwise, physical circumstances may lead to the
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched
on, the system is activated after approx. 1 sec-
ond when you engage reverse gear or move the
automatic transmission selector lever to
position R. Wait this short period before driving.
Switching off automatically
After approx. 165 ft/50 m of driving or above
approx. 20 mph or 30 km/h, the system
switches off and the LED goes out.
Signal tones
When nearing an object, its position is indicated
correspondingly by an interval tone. As the dis-
tance between vehicle and object decreases,
the intervals between the tones become
shorter. If the distance to the nearest object
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx.
3seconds>If you remain in front of an object that has
been detected by only one of the corner
sensors
>If you are driving parallel to a wall.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC is malfunc-
tioning. A message appears on the
Control Display.Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not spray the
sensors for extended periods of time and only
from a distance of at least 12 in/30 cm.
PDC with visual warning
The approach of the vehicle to an object is
shown on the Control Display. Objects that are
farther away are displayed on the Control Dis-
play before a signal tone sounds. The display
appears 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. Therefore, always
drive cautiously; otherwise, there is a risk of
personal injury or property damage.

Technology for driving comfort and safety
78 Loud sound sources outside or inside the car
can drown out the PDC signal. Therefore,
always drive cautiously; otherwise, there is a
risk of personal injury or property damage.<
Driving stability control
systems
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
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 page114.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
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.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing
traction when you pull away from rest or accel-
erate. The system 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 indi-
vidual 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
s a f e t y m a r g i n a g a i n b y t a k i n g r i s k s , a s t h i s c o u l d
result in an accident.<
Deactivating/activating the DSC OFF
program
The program can be deactivated via Dynamic
Driving Control, refer to DSC OFF.
For better control
The indicator lamp flashes: DSC con-
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
DTC Dynamic Traction Control
The concept
The DTC system and the TRACTION program
are a variant of the DSC in which forward
momentum is optimized.
The system ensures maximum forward
momentum on special road conditions, e.g.,
unplowed snowy roads, but driving stability is
limited.
It is therefore necessary to drive with appropri-
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
>When driving in slush or on uncleared,
snow-covered roads.
>When rocking the vehicle or driving off in
deep snow or on loose surfaces.
>When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
The system and program can be deactivated/
activated via Dynamic Driving Control.
