"Vehicle Info"

"Vehicle status"

"Reset"

Start the engine - do not drive away.

Start the initialization using "Reset".

Start to drive.

The initialization is completed during the trip.
"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

209

, the stan-

dard equipment by design, do not continue
driving. 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 bay full, or 4 persons
without luggage:
approx. 90 miles/150 km

With a full load:
4 or more persons, cargo bay 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.

Malfunction

The warning lamps come on in yel-
low. A message appears on the Con-
trol Display. The Flat Tire Monitor has
a malfunction or has failed. Have the

system checked as soon as possible.

Tire Pressure Monitor TPM*

The concept

TPM checks the inflation pressures of the four
mounted tires. The system notifies you if there
is a significant loss of pressure in one or more
tires.
