Tire Pressure Control (RDC)
*
In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, an acoustic
signal is sounded.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the
wheel and flat tire.
The space-saver spare tire is
provided for temporary use only in
the event of a tire failure. It does not
have RDC electronics and is not moni-
tored. A full-size spare tire that has the
same dimensions as the tires already
mounted on the vehicle is equipped
with the necessary RDC electronics,
and will be also be monitored once the
tires have been mounted and the
system activated.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed by your
BMW center.
Your BMW center has been trained to
work with the RDC system and is
equipped with the necessary special
tools.<
System interferenceLocal devices using the same radio
frequency can interfere with the RDC.
The yellow indicator lamp will come on
during the malfunction.
The indicator lamp also comes on
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire
*, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.

Cellular phone
* Radio reception
Mobile communications systems
(cellular phone, radio, etc.) are only
allowed a power output of up to
10 watts. Mobile communications
devices not specifically designed for
use in your vehicle may trigger malfunc-
tions while operating your vehicle.
BMW can neither test nor assume
responsibility for every individual
product being offered on the market.
We recommend that you consult your
BMW center before purchasing 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 compartment or
an antenna that is not 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,
including the broadcast range of the
transmitter and the directional orienta-
tion 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's
sound system is operating.
Climatic factors such as intense solar
radiation, fog, rain and snow can also
interfere with reception.
Car telephones or cellular phones not
approved by BMW can also cause
interference in the radio during a tele-
phone call. This phenomenon assumes
the form of a low-pitched hum
emanating from the speaker system.
Please refer to the Owner's Manual
provided with your sound system for
detailed information on its use.

Radio receptionThe AM frequency bands (medium-
wave, long-wave and short-wave) make
it possible to receive stations from a
great distance, because the broadcast
signals travel not only along the ground
as surface waves, but also as
atmospheric waves that are reflected
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
minimized by a number of innovative
system designs:
The "Radio Data System" (RDS) makes
sure that, for broadcast stations
sending on several frequencies, the
radio 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.

Tire Pressure Control (RDC)
*
This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you don't have to.
Behind the valve stem in every wheel,
there is an electronic chip that 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 transmitted
by a radio signal. If an irregularity is
detected, the transmission rate is
increased. 460de169
Near every wheel is an antenna in the
body that receives the signal from the
wheel. A central electronics system
evaluates the quadruple signals and
forwards any changes.
The RDC provides an important contri-
bution to driving safety.
