This symbol will appear in the
Check Control panel to inform you
when the inflation pressure varies
from that stored in the system. A text
message appears at the same time. Please
take note of the additional information in
the Control Display panel.
You can find more information on the
Check Control starting on page 80.
The RDC cannot alert you to severe
and sudden tire damage caused by
external factors.<
To initialize the system 1.With the vehicle parked, switch on the
ignition
2.Select "RDC" from the "Settings" menu
and confirm your selection. The initializa-
tion menu appears. "INITIALIZE" 1.Select and confirm
2.RDC is initialized. A message appears in
the Check Control panel
3.After several minutes of driving RDC will
adopt the tires' current inflation pressures
as its references.
The current data appear in the Control
Display. These figures are more accurate than those that appear on the inflation
gauges at filling stations, etc.
The only time you will need to repeat this
procedure is after correcting your tire pres-
sures. Because RDC automatically
assumes operation each time you switch
on the ignition, it is on duty whenever you
drive.
If the system detects a flat tire during
the initialization process, the tires in
the Control Display will appear in red.<
Do not start initialization
Select and confirm to return to the
"Settings" menu.
Status indicators in the Control
Display The status of the system is indicated by the
color of the tires. GreenTire inflation pressures correspond to the
initialized level.YellowThe inflation pressures in the tires have
fallen to below the specified level, which is
normal in every tire after a certain amount
of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible. RedPressure loss in indicated tire.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. BlackThe system is being initialized.
The system needs several minutes to
complete the initialization process, after
which it is ready to detect and report tire
problems.

Technology for comfort, convenience and safety

In the event of loss in tire pressure If the indicator lamp symbol in the Check
Control lights up in yellow, and a message
also appears, this indicates that the infla-
tion pressures in the tires have fallen to
below the specified level, which is normal
in every tire after a certain amount of time.
This alerts you to have the tires inflated to
the specified pressures as soon as
possible.
Please take note of the additional informa-
tion in the Control Display panel.
If you are prompted to check the tire
pressure shortly after a correction 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. Then reinitialize the
system.< Flat tire If you have a flat tire, the indicator lamp
symbol in the Check Control will light up in
red, and a message will appear. In addition,
a gong sounds.
If this occurs, reduce vehicle speed imme-
diately and stop the vehicle. Avoid hard
and sudden steering and braking maneu-
vers. Replace the damaged tire.
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support RDC operation;
once the spare tire is installed, the pressure
in this tire will also be monitored following
system initialization.
Have the tires changed at your BMW
center. Your BMW center has the informa-
tion needed for working with RDC and is
equipped with the necessary special
tools. radio frequency as RDC can generate inter-
ference signals that may prevent the
system from operating as intended. The symbol will appear in yellow in the
Check Control panel and a message will
appear.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
appropriate electronics
>if, in addition to the spare tire, additional
wheels with RDC electronics are on board.
Please refer to the additional information
supplied in the Control Display, and have
the system inspected at your BMW center.
Self-leveling suspension*

In the event of malfunction
A Check Control message
appearing together with this symbol
indicates a malfunction in the self-
leveling suspension. Please take note of
the additional information in the Control
Display panel.
Stop and inspect the vehicle. If the rear of
the vehicle is visibly lower than the front,
possibly accompanied by a tilt noticeable
when you compare the left rear with the
right rear, you should respond by immedi-
ately proceeding to the nearest BMW
center. Drive with appropriate caution in
the meantime. The vehicle has reduced
ground clearance and driving comfort may
be noticeably reduced. Even if the attitude
of the vehicle is normal, you should consult
the nearest BMW center if the warning
lamp indicates a system fault.
