Indication of a flat tire
suitable location. Otherwise parts of the tire
could come loose, resulting in an accident. Do
not continue driving. Instead, contact your
BMW center.<
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.
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.
1.
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 219, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result if you continue driving.<
Tire Pressure Monitor TPM*
The concept
2.
3.
At the next opportunity, check the air pres-
sure in all four tires.
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.
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.<
Functional requirement
In the event of complete tire pressure loss,
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
0
psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
>
With a light load:
1 to 2 persons without luggage:
approx. 155 miles/250 km
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
>
With a medium load:
2 persons, cargo bay full, or 4 persons
without luggage:
approx. 90 miles/150 km
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
>
With a full load or when towing a trailer:
4 or more persons, cargo bay full:
approx. 30 miles/50 km
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
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
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as
a compact spare wheel, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
