rupted at any time. When driving resumes, the
reset is continued automatically. On the Control
Display, the tires are shown in green and "Sta-
tus: TPM active" is shown again.

If a flat tire is detected while the system is
resetting and determining the inflation

pressures, all tires on the Control Display are
displayed in yellow. The message "Tire low!" is
shown.

Message for low tire inflation pressure

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

tial loss of tire pressure.

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 car is not equipped with Run-
Flat Tires, refer to page

, the stan-

dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture if you continue
driving.

In the event of complete 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. 95 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/80 km/h. 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 small warning lamp flashes in
yellow and then lights up continu-
ously; the larger warning lamp comes
on in yellow. On the Control Display,

the tires are shown in gray and a message
appears. No punctures can be detected.
his type of message is shown in the following
situations:

If there is a malfunction
Have the system checked.

If a wheel without TPM electronics has
been mounted

If TPM is temporarily malfunctioning due to
other systems or devices using the same
radio frequency.

Message for unsuccessful system
reset

Both warning lamps come on in yel-
low. A message will appear on the
Control Display. The system is not
reset after a tire has been changed,

for example.
Check the tire inflation pressure and reset the
system, refer to page

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
