Tire inflation pressureThe 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 indicated
in psi (kilopascal) for tires at ambient
temperature (refer also to the next
pages).
Vehicles with Tire Pressure Monitor
(RDC)
*:
After correcting tire inflation pressures,
reactivate the system, refer to
page 101.
390de697
Check tire inflation pressures on a
regular basis Ð at least twice a
month Ð and before every extended
journey. Incorrect tire pressure can lead
to driving instability, tire damage and
accidents.
Check the inflation pressure of the
spare tire also. Inflate the spare tire to
the highest pressure of any tire on your
vehicle.<
Comply with tire approval
specificationsThe inflation pressures in the tables
apply to BMW approved tire sizes and
tire manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers.
Your vehicle is equipped with tires that
not only meet US, but also European
standards. We recommend the exclu-
sive use of BMW approved tires.

Self-leveling suspension
*
Tire Pressure Monitor (RDC)
*
The warning lamp for the self-
leveling suspension comes on,
or the message "SELFLEVEL
SUSP.INACT" appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If it is
riding significantly lower in the rear than
in the front, or if it is sitting at an incline
(left rear compared to right rear), con-
sult the nearest BMW center. Drive with
appropriate caution in the meantime.
The vehicle has reduced ground clear-
ance or driving comfort is noticeably
reduced.
Even if the attitude of the vehicle is
normal, you should consult the nearest
BMW center if the warning lamp indi-
cates a system fault.
The conceptRDC 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 system to "learn" the
correct tire inflation pressure, check the
inflation pressure in all tires. Refer to
the table of "Tire inflation pressures"
beginning on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol will inform you if the tire
pressure is not correct.
Activate the system1. Turn the ignition key to position 2 (do
not start the engine)
2. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message "SET
TIRE PRESSURE" appears in the
Check Control panel
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference values which the system
will monitor.
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.390de704

102n
Tire Pressure Monitor (RDC)*Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly (which is normal for any tire),
the yellow indicator lamp comes on or
the message "CHECK TIRE PRES-
SURE" appears 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
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table.<
Flat tireIf there is a tire failure with a loss of
inflation pressure, the red indicator
lamp comes on or the message "TIRE
DEFECT" appears in the Check Control.
In addition, a gong sounds.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. 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
after it is mounted.<
The RDC cannot alert you to
severe and sudden tire damage
caused by external factors.<
Have the tires changed at your
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 INAC-
TIVE" 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, addi-
tional wheels with RDC electronics
are on board.
Please contact your BMW center for
additional information.
