ing driving. The tires are shown in green on the
Control Display.

If a flat tire is detected during resetting
and applying the tire inflation pressures,

all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.

Message with low tire inflation

pressure

The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal

sounds. There is a flat tire or extensive inflation
pressure loss.

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.

Stop driving if the vehicle is no longer
equipped with run-flat tires, as it was

when it came from the factory, refer to

. Continued driving after a flat tire

can result in serious accidents.

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 low load:
1 to 2 persons without luggage:
approx. 155 miles/250 km

With medium load:
2 persons, cargo bay full, or
4 persons without luggage:
approx. 95 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 distances 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.

Malfunction

The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-

play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:

In case of a malfunction;
have the system checked.

If a wheels is mounted without TPM elec-
tronics.

If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.

Declaration according to NHTSA/

FMVSS 138 Tire Pressure Monitoring
Systems

Each tire should be checked monthly when cold
and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If
your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire infla-
tion pressure label, you should determine the
proper tire inflation pressure for those tires. As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys-
tem, TPMS, that illuminates a low tire pressure
indicator when one or more of your tires are sig-
nificantly under-inflated. Accordingly, when the
low tire pressure indicator illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping ability. Please
note that the TPMS is not a substitute for
