Tire inflation pressure The inflation pressures are indicated on
a sticker attached to the B-pillar behind
the driver's door (visible with door
open).Check tire pressuresAll pressure specifications are stated in
psi (kilopascal) with cold tires (cold =
ambient temperature). Refer to the next
page as well.
For trailer towing, the inflation pressure
for heavier loads always applies.
For vehicles with RDC (Tire Pressure
Control)
*:
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 82.
462de197
Check tire inflation pressures reg-
ularly – at least every two weeks
and before beginning a longer trip. In-
correct tire pressure can otherwise lead
to tire damage and accidents.
Also check the inflation pressure of the
space-saver tire or spare tire
*. Inflate
the spare tire to the highest inflation
specified for your vehicle.<
Comply with tire approval
specificationsThe inflation pressures in the table apply
to tires from BMW-approved manufac-
turers. Your BMW center is familiar with
these pressures. Higher pressures may
be specified for tires from other manu-
facturers. You will find a list of approved
tires beginning on page 117.

Tire Pressure Control (RDC)
*
The conceptThe RDC monitors the tire pressures at
all four wheels, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the RDC to "learn" the cor-
rect tire inflation pressure, first check
the tire inflation pressure in all tires.
Then compare these pressures with the
tire inflation pressure chart (page 28)
and adjust if necessary. Then activate
the system.
This indicator lamp in the instru-
ment cluster informs you when-
ever the tire pressure is not nor-
mal.
Activate the system1 Turn ignition key to position 2
2 Press the switch long enough for the
indicator lamp in the instrument clus-
ter to light up yellow for a few seconds
3 After a few minutes of driving, the
RDC sets the current inflation pres-
sure in the tires as the target value to
be monitored.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.462de228
Loss of tire pressureIf the inflation pressure has dropped too
much over a period of time (which is
normal for any tire), the indicator lamp
will come on with a yellow lamp.
This alerts you to 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.
Then activate the system once again.<

Flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with
a red lamp. In addition, there is an
acoustical warning signal.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a save
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 case 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 also be monitored once the
tires have been mounted and the sys-
tem activated.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your authorized BMW center has been
trained to work with the RDC system
and is equipped with the necessary
special tools.<
System interferenceThe RDC can be subjected to interfer-
ence locally by outside equipment or
devices which use the same radio fre-
quency.
The indicator lamp will come on with
a yellow lamp 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 authorized BMW
center for additional information.
