Tire Pressure Control (RDC)
*
Loss of tire pressureIf, after a certain period of time, the air
pressure has gone down significantly
(which is normal for any tire), the yellow
indicator lamp comes on or the mes-
sage "CHECK TIRE PRESSURE" ap-
pears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.<
Flat tireIf there is a tire failure with a loss of air
pressure, the red indicator lamp comes
on or the message "TIRE DEFECT" ap-
pears in the Check Control. In addition,
a gong sounds.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a safe
location. Avoid hard brake applications.
Do not oversteer. Replace the flat tire.
The spare tire which is available in
your vehicle as standard equip-
ment is equipped with the electronics
required for RDC and, following activa-
tion of the system, is also monitored af-
ter it is mounted.<
The RDC cannot alert you to se-
vere and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceDuring the period of the malfunction,
the yellow indicator lamp comes on
or the message "TIRECONTROL
INACTIVE" appears in the Check
Control.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire,
additional wheels with RDC
electronics are on board.
Please contact your BMW center for
additional information.
