Power steering Cellular phone* Radio reception Changes in steering response, e.g. high
steering effort:
Consult a BMW center to have the sys-
tem checked.
If the power steering fails, in-
creased effort will be required to
steer the vehicle.<
Only mobile communications systems
(cellular phone, two-way radios, etc.)
with an output up to 10 watts are per-
mitted. Mobile communications devices
not specifically designed for use in your
vehicle may trigger malfunctions while
operating your vehicle. BMW can nei-
ther test nor assume responsibility for
every individual product being offered
on the market. We recommend that you
consult your BMW center before pur-
chasing 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, structural or
natural obstructions can all lead to un-
avoidable reception interference, re-
gardless 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.
Car telephones or cellular phones not
approved by BMW can also cause in-
terference in the radio during a tele-
phone call. This phenomenon assumes
the form of a low-pitched hum emanat-
ing from the speaker system.
Please refer to the supplementary
Owner's Manual provided with your car
radio
* 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 atmospheric waves that are re-
flected from the ionosphere.
Frequency-modulation (FM) provides
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 min-
imized by a number of innovative sys-
tem designs:
The "Radio Data System" (RDS) makes
sure that, for stations broadcasting on
several frequencies, the radio automati-
cally tunes to the frequency with the
best reception quality.
With the Diversity Antenna system, sev-
eral FM antennas are integrated within
the convertible top compartment lid to
provide three separate sources for re-
ceiving broadcast waves. An integral
processor automatically selects the an-
tenna with the best FM reception qual-
ity at any given time. The selection of
the antenna takes place within millisec-
onds, and is therefore not noticed by
the radio listener.The safety belt tensioners respond to
severe head-on collisions by tightening
the belts to ensure that occupants
remain firmly positioned in their seats.
A gas-pressure system retracts the
buckle assembly to tension the shoul-
der and lap belts within fractions of a
second. This reduces the tendency to
slide under the lap belt.

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 de-
signed for severe-duty applications
and long service life. It 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 transmis-
sion rate is increased. 46cde078
There is an antenna located right near
every wheel in the vehicle body. Each
antenna picks up signals from its re-
spective wheel. A central electronics
system evaluates all four signals and
forwards any changes. The RDC pro-
vides an important contribution to
driving safety.
