System has not been initialized

Driving on snowy or slippery road surface

Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration

Snow chains are attached

Initializing the system

The initialization is completed during driv-
ing, which can be interrupted at any time.

When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.

"Status: Flat Tire Monitor active" is displayed
again on the Control Display.

Indication of a flat tire

The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, an
acoustic signal sounds. There is a flat

tire or substantial loss of tire pressure.

Cautiously reduce speed to below 50 mph
or 80 km/h. Avoid sudden braking and
steering maneuvers. Do not exceed a speed
of 50 mph or 80 km/h.

If the car is not equipped with run-flat
tires, refer to page

216

, the standard

equipment by design, do not continue driv-
ing. Otherwise, a severe accident could
result if you continue driving.

At the next opportunity, check the air pres-
sure in all four tires.

If all four tires are inflated to the cor-
rect pressures, the Flat Tire Monitor

might 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 guidelines:

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

With a medium load:
2 persons, cargo area full, or 4 persons
without luggage:
Approx. 90 miles/150 km

With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km

Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h; otherwise,

there is a risk of an accident. In the event of
pressure loss, vehicle handling changes. This
includes reduced tracking stability in braking,
extended braking distance and altered natural
steering characteristics.
If unusual vibration or loud noises occur during
the journey, this may be an indication that the
damaged tire has finally failed. Reduce your
speed and pull over as soon as possible at a
suitable location. Otherwise, parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.

Status display

The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.
