Technology for driving comfort and safety
86 iDrive, for operating principle refer to page16.
1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine - do not drive away.
5.Start the initialization using "Reset".
6.Start to drive.
The initialization is completed during the trip.
"Status: Flat Tire Monitor active" is displayed
again on the Control Display.
Indication of a flat tire
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.
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 page204, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result if you continue driving.<
2.At the next opportunity, check the air pres-
sure in all four 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.<
3.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 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:
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, 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
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.
Gray
The system cannot detect a puncture.
Possible reasons for this:
>TPM is being reset
>Temporary malfunction caused by systems
or devices using the same radio frequency
>Malfunction
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
iDrive, for operating principle refer to page16.
1."Vehicle Info"
2."Vehicle status"
3."Reset TPM"
4.Start the engine - do not drive away.
5.Start the initialization using "Reset TPM".
6.Start to drive.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the target
values to be monitored. The system reset is
completed during your drive, and can be inter-
rupted at any time. When driving resumes, the
reset is continued automatically. On the Control
Display, the tires are shown in green and
"Status: TPM active" is displayed again.

Technology for driving comfort and safety
88 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.
1.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 page204, the stan-
dard equipment by design, do not continue
driving. Otherwise a severe accident could
result after a tire puncture if you continue
driving.<
2.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 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.
This 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
The warning lamp lights up yellow. 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 page87.
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
telltale when one or more of your tires are signif-
icantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should
