Radio reception Safety belt tensionerThe radio waves — medium-wave, long-
wave and short-wave — offer a wide
range of reception, because the broad-
cast signals travel not only along the
ground as surface waves, but also as
atmospheric waves bounced back to
earth from the ionosphere.
Frequency-modulation (FM) provides
substantially better sound quality than
AM. However, because FM transmis-
sions rely on line-of-sight broadcast
waves, their effective reception range is
limited. 360de084
The limitations inherent to radio recep-
tion in a moving vehicle have been min-
imized by a number of innovative sys-
tem designs:
The "Radio Data System" (RDS) makes
sure that, for broadcast stations trans-
mitting on several frequencies, the ra-
dio automatically tunes to the frequency
with the best reception quality.
The Diversity Antenna system employs
several FM antennas integrated within
the rear window to provide three sepa-
rate sources for receiving broadcast
waves. An integral processor automati-
cally selects the antenna with the best
FM reception quality at any given time.
The selection of the antenna takes
place within milliseconds, and is there-
fore not noticed by the radio listener.The safety belt tensioner responds to
collisions by tightening the belts to en-
sure that occupants remain firmly posi-
tioned in their seats. A gas-pressure
system retracts the buckle assembly
to tension the shoulder and lap belts
within fractions of a second. This re-
duces the tendency to slide under the
lap belt.

Self-diagnostics All of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically – the driver
does not have to perform any extra op-
erations or adjustments.
The indicator lamps also come on briefly
after the ignition has been turned on.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, sunroof, etc.) is constantly ana-
lyzed by current measurements in their
relays. 462de258
In the same manner, the electrical resis-
tance of the airbag ignition generators
and all of the remaining airbag compo-
nents is measured at all times. Any fault
in this system would be detected imme-
diately by a current fluctuation that
would necessarily accompany it. The
fault would be indicated immediately by
the airbag warning lamp.
Even after you shut off the engine, the
overall functional status of your vehicle
is monitored. For example, all of the
flaps of the heating and ventilation sys-
tem travel to the nearest limit position.
This action ensures that the system will
be able to provide defrosting, regard-
less of other circumstances (if a mal-
function in the heating or ventilation
system should occur during the night
while the vehicle is parked, for in-
stance).
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating
and ventilation flaps travel to their limit
stops in both directions. The limit posi-
tions and the return travel paths are
checked in this manner in order to en-
sure that appropriate adjustments for
the operating elements can be made at
any time.You will hear the sounds of the air flaps
as the heater/ventilation system carries
out its self-diagnostic functions after
the ignition is shut off. All of the other
self-diagnostics functions operate si-
lently in the background.
Any faults detected during these self-
diagnostics can be read out by your
authorized BMW center during the next
regularly-scheduled maintenance and
corrected with a minimum of time.
