2000 BMW 540I SEDAN radio

90n
The PDC assists you when you are
parking. A signal warns you of the real
distance to an obstacle. To do this, four
ultrasonic sensors in the rear bumper
measure the distance from the nearest
object. The monitoring range for the
two corner sensors ends approx. 2 feet
(60 cm) beyond the respective bumper.
The range of the two middle sensors is
approx. 4.9 feet (1.50 meters) outward.
The system starts to operate automati-
cally about one second after you select
reverse with the ignition key in posi-
tion 2. It is similarly deactivated when
you engage reverse gear or move the
selector lever position from the "R" po-
sition.
Acoustical signalsThe distance to the nearest object is in-
dicated by a tone sounding at various
intervals. As the distance between vehi-
cle and object decreases, the intervals
between the tones become shorter. A
continuous tone indicates the presence
of an object less than 1 ft. (30 cm)
away.
The warning signal will be canceled af-
ter approx. 3 seconds if the distance to
the obstruction remains constant during
this time (if you are moving parallel to a
wall, for instance).
System malfunctions will be indicated
by a continuous high-pitched tone
when the system is activated the first
time. Please have the cause checked
and corrected by your authorized BMW
center.The PDC does not remove the
driver's personal responsibility for
evaluating the distance between the ve-
hicle and any obstacles. Even when
sensors are involved, there is a blind
spot in which objects cannot be de-
tected. This applies especially in those
cases where the system approaches
the physical limits of ultrasonic mea-
surement, 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 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 approx. 4 inches (10 cm).<

Radio reception
Mobile communications systems (cellu-
lar phone, radio, etc.) are permitted with
an output up to 10 watts only. Even
these systems may trigger malfunctions
in the operation of your vehicle if they
are not specifically designed for use
with the vehicle. BMW can neither test
nor assume responsibility for every
individual product being offered on the
market. We recommend that you con-
sult your BMW center before purchas-
ing any device of this kind.
To ensure that your BMW continues to
provide reliable and trouble-free opera-
tion, do not use a cellular phone or
other radio device with an antenna
located inside the passenger compart-
ment. The antenna should always be
mounted on the outside of the vehicle.
Before loading the vehicle on a
car-carrier train or driving it
through a car wash, remove the
antenna.<
The reception and sound quality
obtained from mobile radios varies
according to a variety of factors, includ-
ing the broadcast range of the transmit-
ter and the directional orientation of the
antenna. Interference factors such as
high-tension power lines, buildings and
natural obstructions can all lead to
unavoidable reception interference,
regardless of how well the vehicle
sound system is operating.
Climatic factors such as intense solar
radiation, fog, rain and snow can also
interfere with reception.
Cellular phones without official BMW
approval can also generate interfer-
ence. This phenomenon assumes the
form of a low-pitched hum emanating
from the speaker system.
Please refer to the (Supplementary)
Owner's Manual provided with your
sound system for detailed information
on its use.

Radio reception BMW active seat

AM provides substantially longer recep-
tion ranges than FM. AM broadcast
signals, propagated at ground level in
the form of surface waves, are also
reflected from the ionosphere as
atmospheric waves.
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
Although numerous factors combine
to impose inherent limitations on the
reception quality available from mobile
radios, specially designed systems can
be employed to minimize their effects:
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.
Because the ongoing antenna selection
process is completed within milli-sec-
onds, it remains inaudible to the radio
listener.BMW seats are configured for your
orthopedic well-being. The active seat
is an engineering enhancement of
BMW's seats, designed to ensure less
fatigue during extended trips while
sitting with little movement. The seat is
no longer a passive element between
the road, the running gear and the pas-
senger. Instead, it creates minor and
imperceptible shifts in your weight by
an active change in the contour of the
seat surface. The basic seat position is
not changed as this occurs.
Fluid cushions are located below the
surface of the seat in the seat's
upholstery on the left and right. The
fluid is circulated slowly back and forth
between the two cushions by means of
a pump. This causes a movement of the
spinal column which is nearly unnotice-

Tire Pressure Control (RDC)
*
Integrated rear suspension
The Tire Pressure Control system (RDC)
assumes the task of regular tire pres-
sure checks for you. The tire pressure is
monitored at all four wheels, even when
the vehicle is moving.
Behind the valve stem in every wheel,
there is an electronic chip which is
designed for severe-duty applications
and long service life. It contains a pres-
sure sensor, a transmitter and a battery.
The pressure is measured in extremely
short time intervals and then transmit-
ted by a radio signal. If an irregularity is
detected, the transmission rate is
increased.394de304
Near every wheel, there are antennas in
the body which receive the signals from
all four wheels. A central electronics
system evaluates the quadruple signals
and forwards any changes.
The RDC provides an important contri-
bution to driving safety.
The control arms on the patented inte-
grated aluminum rear axle assembly are
not mounted directly on the body. They
are mounted elastically on a chassis
sub-frame which is joined in turn with
elasticity to the vehicle body. The result-
ing double elastic suspension system
effectively absorbs the forces resulting
from bumps and road surface irregulari-
ties.
The compliance rates of the integrated
rear axle assembly's control arm mounts
have been precisely calibrated to help
provide supplementary adjustment in
the tracking angle of the rear wheels
(programmed self-steer effect). The ulti-
mate result is enhanced safety and con-
trol under all conditions.
The illustration shows the rear axle of the
sedan. With the lightweight, compact
rear axle of the sport wagon, the shock
absorbers are positioned at an angle.
