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.

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.

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

. Continued driving after a flat tire 

can result in serious accidents.

<

2.

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.

<

3.

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:

>

With a light load: 
1 to 2 persons without luggage: 
approx. 155 miles/250 km

>

With a medium load: 
2 persons, cargo bay full, or 
4 persons without luggage: 
approx. 94 miles/150 km

>

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-

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.

<

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 order to assure the reliable reporting of a flat 
tire, the system must have been reset with the 
correct tire inflation pressure.
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.

<

TPM cannot announce sudden serious 
tire damage caused by external influ-

ences.

<

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.

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.
