44nAlarm system
>If the indicator lamp flashes for
10 seconds when the system is
disarmed: an attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the
indicator lamp will flash continuously.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. To prevent a false alarm from
being triggered (in garages with
elevator ramps, for instance), or when
the vehicle is transported by trailer or
train:
Actuate the lock (= arm the system)
twice; in other words, press button 2 of
the remote control twice in succession
(refer to page 38). You may also actuate
the locks twice with the key (refer to
page 36).
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated as long as the system is
armed.
Interior motion sensor
The illustration depicts the transmitter
and receiver of the interior motion
sensor.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
However, be sure to deactivate the
interior motion sensor (see the previous
column) when you wish to leave the
windows or sliding/tilt sunroof open.

PDC
*
Dynamic Stability Control (DSC)
The PDC system does not remove
the driver's personal responsibility
for evaluating the distance between the
vehicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be
detected. This applies especially in
those cases where the system
approaches the physical constraints of
ultrasonic measurement, as occurs with
tow bars and trailer couplings, and in
the vicinity of thin and painted objects.
Certain sources of sound, such as a
loud radio, could drown out the PDC
signal tone.<
Keep the sensors clean and free
of ice or snow in order to ensure
that they continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Maintain an adequate distance of more
than 4 in (10 cm).<
The concept DSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, keeps the car on a steady
course by adapting the RPMs and
brake applications to the individual
wheels.
The system starts up automatically
each time you start the engine.
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to page 24.
Indicator lamp flashes:
The system is active and governs drive
and braking force.
If the indicator lamp fails to go out after
the engine is started, or comes on
during normal driving and stays on:
The system is either defective or was
switched off with the button: the stabi-
lizing applications described to the left
are no longer available. The vehicle will
remain completely operational,
however, without DSC.
Consult your BMW center to have the
system repaired.
