Check the air pressure in all four tires at the
next opportunity.
TPM Tire Pressure Monitor*
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
In the event of complete tire pressure loss,
0
psi/0 kPa, you can estimate the possible
distance for continued driving on run-flat
tires, based on the following guide values:
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
>
With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
>
With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
>
With full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km.
System limits
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tances and altered natural steering charac-
teristics.
If unusual vibrations or loud noises occur
while the vehicle is being driven, this can
indicate final failure of the damaged tire.
Reduce speed and stop at a suitable loca-
tion as soon as possible; otherwise, pieces
of the tire could become detached and
cause an accident. Do not continue driving,
but instead contact your BMW center.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
