4. Select "FTM" and press the controller.
5. Start the engine, but do not start driving.
6. Select "Set tire pressure" and press the
controller.
7. Select "Yes" and press the controller.
8. Start to drive.
The message "Initializing..." is displayed.
The initialization is completed during driving.
Then the message "Status: FTM active"
appears on the Control Display again.
Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. 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 sudden brak-
ing and steering maneuvers. Do not exceed
a vehicle 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 192. Continued driving after a flat tire
can result in serious accidents.<
2. Check the air pressure in all four tires at the
next opportunity.
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 run-flat
tires, based on the following guide values:
> With low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km.
> With medium load:
2 persons, luggage compartment full, or
4 persons without luggage:
approx. 94 miles/150 km.
> With 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-
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.<
TPM Tire Pressure Monitor*
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.
