8. Select "Yes" and press the controller.
9. Start to drive.
The message "resetting FTM ..." is dis-
played.
The initialization finishes during driving. Then
the message "Status: active" appears on the
Control Display again.
Indication of a flat tire
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. Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2. Identify damaged tire.
If identification is not possible, con-
tact a BMW center.<
3. Replace the damaged wheel, refer to
Changing wheels on page 226.
Run-flat tires*
1. Cautiously reduce speed to below 50 mph/
80 km/h. Avoid sudden braking and steer-
ing maneuvers. Do not exceed a speed of
50 mph/80 km/h.
If the vehicle is not equipped with run-
flat tires, refer to page 213, do not
continue driving. Continuing to drive with a
flat tire could cause severe
2. At the next opportunity, check the air pres-
sure in all four tires.

pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
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 location as soon as possible,
otherwise pieces of the tire could become
detached and cause an accident. Do not con-
tinue 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.
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.
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.<
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 or more persons, cargo bay full:
approx. 30 miles/50 km
Drive reservedly and do not exceed a
speed of 50 mph/80 km/h. In the event of
