Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
>Snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
iDrive, for operating principle refer to page16.1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.
5.If necessary, move the highlight marker to

troller.
6.Start the engine, but do not start driving.
7.Select "Reset" and press the controller.
8.Select "Yes" and press the controller.
9.Start to drive.
Initialization is completed while the car is in
motion.

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 page212, 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.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 or when towing a trailer:
4 or more 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.
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.Press the button
The start menu is called up.
2.Press the controller to open the menu.3.Select "Settings" and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.
5.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "TPM" is selected and press the con-
troller.
6.Start the engine, but do not start driving.
7.Select "Reset" and press the controller.
8.Select "Yes" and press the controller.
9.Start to drive.

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.
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 page212, the stan-

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 page92.
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
