Tire Pressure Control (RDC)
*
In the event of a flat tire
If 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 to stop the vehicle in a safe
location. Avoid hard brake applications.
Do not oversteer. Replace the wheel
and flat tire.
The space-saver spare tire is
provided for temporary use only in
the event of tire pressure loss. It does
not have RDC electronics and is not
monitored. A full-size spare tire that has
the same dimensions as the tires
already mounted on the vehicle is
equipped with the necessary RDC elec-
tronics, and will be also 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 interference
Local 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.
