Do not start the 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.
TPM takes into account that the tire pres-
sure changes during driving. A correction is
only required when the TPM requests that
the driver takes action by changing the
color.
Green
Tire inflation pressures correspond to the
initialized level.
Yellow
The 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 pos-
sible.
Red
Pressure 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.
Black
The system is being initialized.
The system needs several minutes to com-
plete the initialization process, after which
it is ready to detect and report tire prob-
lems.
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 pos-
sible.
Please take note of the additional informa-
tion in the Control Display.
If you are prompted to check the tire
pressure shortly after a correction has
been made, this indicates that the cor-
rected 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.
> Vehicles with standard tires:
If this occurs, reduce vehicle speed
immediately and stop the vehicle. Avoid
hard and sudden steering and braking
maneuvers. Replace the defective tire
> Vehicles with run-flat tires:
If this occurs, carefully but quickly
reduce vehicle speed to below 50 mph
(80 km/h). Avoid hard and sudden
steering and braking maneuvers.
Additional information on run-flat tires
is provided on page
186 .
The spare tire provided with your
vehicle is equipped with the elec-
tronics required to support TPM operation;
once the spare 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 information
needed for working with TPM and is
equipped with the necessary special
tools.

System malfunctions
Other equipment operating on the same
radio frequency as TPM can generate inter-
ference signals that may prevent the
system from operating as intended.
