Indication of a flat tire
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 warning lamp lights up red. A mes-
sage appears on the Control Display.
In addition, an acoustic signal sounds.
There is a flat tire or extensive inflation pressure
loss.
TPM Tire Pressure Monitor*
1.
Cautiously reduce the vehicle speed to
below 50 mph/80 km/h. Avoid severe brak-
ing and steering maneuvers and do not
exceed a speed of 50 mph/80 km/h.
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.
Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was
when it came from the factory, refer to
page 218. Continued driving after a flat tire
can result in serious accidents.<
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.
2.
3.
At the next opportunity, check the air pres-
sure in all four tires.
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.<
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
In the event of complete tire pressure loss,
0
psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guide values:
System limits
>
With a light load:
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
1 to 2 persons without luggage:
approx. 155 miles/250 km
>
With a medium load:
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
2 persons, cargo bay full, or
4 persons without luggage:
approx. 94 miles/150 km
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.
>
With a full load:
4 persons, luggage compartment full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the
event of pressure loss, vehicle handling
changes. This includes reduced tracking
stability in braking, extended braking dis-
tance 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-
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.
