chnology for

driving comfort

and

safe

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 or when towing a trailer:
4 persons, cargo bay full:
approx. 30 miles/50 km

Drive cautiously and do not exceed a
speed of 50 mph or 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 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.

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.

Always use wheels with TPM electronics. Oth-
erwise, the system may malfunction.

Each time a tire inflation pressure has
been corrected or a wheel or tire has been

changed, reset the system.

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.

Green

The tire inflation pressure corresponds to the
established target value.
"TPM active" appears on the Control Display.

One wheel yellow

There is a flat tire or substantial loss of tire pres-
sure in the indicated tire. A message appears on
the Control Display.

All wheels yellow

There is a flat tire or substantial loss of tire pres-
sure in several tires. A message appears on the
Control Display.
