In the event of complete tire pressure loss,
Tire Pressure Monitor TPM*
0
psi/0 kPa, you can estimate the possible
distance for continued driving on the basis
of the following guidelines:
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.
>
With a light load:
1 person without luggage:
approx. 155 miles/250 km
>
With a medium load:
1 person, cargo bay full, or 2 people
without luggage:
approx. 90 miles/150 km
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
>
With a full load:
2 people, cargo bay full:
approx. 30 miles/50 km
Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.
Drive cautiously and do not exceed a
speed of 50 mph or 80 km/h, otherwise
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
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.<
System limitations
TPM cannot warn you in advance of sud-
den severe tire damage caused by out-
side influences.<
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.
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.

Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
TPM takes into account that tire pressures
change while the vehicle is being driven. The
tire pressures do not need to be corrected
unless the TPM instructs you to do so by means
of color indicators.
The status is displayed.
