Power steering Cellular phone
* Radio reception
If the steering response changes, e.g.
high steering effort:
Have your BMW center inspect the
system.
If the power steering fails,
increased effort will be required to
steer the vehicle.<
Mobile communications systems
(cellular phone, radio, etc.) are
permitted with an output up to 10 watts
only. Mobile communications devices
not specifically designed for use in your
vehicle may trigger malfunctions 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 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,
including the broadcast range of the
transmitter and the directional orienta-
tion of the antenna. Interference factors
such as high-tension power lines, build-
ings and natural obstructions can all
lead to unavoidable reception interfer-
ence, 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 reception Safety belt tensionerThe 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 atmo-
spheric waves that are reflected from
the ionosphere.
Frequency modulation (FM) offers
substantially better sound quality than
the other frequencies. However,
because FM transmissions rely on line-
of-sight broadcast waves, their effec-
tive 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 Antenna Diversity 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
therefore not noticed by the radio
listener.The safety belt tensioner makes sure
that the belt tightens during a head-on
collision to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the
shoulder and lap belts within fractions
of a second. This reduces the tendency
to slide under the lap belt.

Tire Pressure Control* Self-diagnostics This system regularly checks tire pres-
sure and monitors all four tires even
while driving, so you do not have to.
Behind the valve stem in every wheel,
there is an extended-life electronic chip
that contains a pressure 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.
Located near each wheel and
embedded in the vehicle body is an
antenna that receives signals 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.46cde078
All
of the important electrical and elec-
tronic systems in the vehicle are tested
regularly and automatically Ð the driver
does not have to perform any extra
operations or adjustments.
The indicator lamps come on brießy
after the ignition has been turned on, for
example.
While you are driving, the functional
status of the actuator motors (for the
windshield wipers, power windows,
seats, etc.) is constantly being analyzed
by electrical measurements in the relays.
In the same manner, the electrical
resistance of the airbag ignition genera-
tors and all of the remaining airbag
components is measured at all times. Any
fault in this system would be detected
immediately by a current ßuctuation that 46cde052
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 ßaps of
the heating and ventilation system travel
to the nearest limit position. This action
ensures that the system will be able to
provide defrosting, regardless of other
circumstances, e. g. if a malfunction in the
air conditioner/automatic climate control
system
* should occur during the night
while the vehicle is parked.
A calibration cycle runs every tenth time
the engine is shut off. During this cycle,
the actuator motors of all the heating and
ventilation ßaps travel to their limit stops
in both directions. The limit positions and
the return travel paths are checked in this
manner in order to ensure that appro-
priate adjustments for the operating
elements can be made at any time.
You will hear the sounds of the air ßaps as
the air conditioner/automatic climate
control* carries out its self-diagnostic
functions after the ignition has been shut
off. All of the other self-diagnostics func-
tions operate silently in the background.
Any possible faults detected during these
self-diagnostics can be read out and
corrected by your BMW center
during the
next regularly scheduled maintenance.
