TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset at the correct tire
inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<

System limits
TPM cannot announce sudden serious tire
damage caused by external influences.
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
All wheels are yellow
Flat tire or a major drop in inflation pressure in
several tires. A message appears on the Control
Display.
Gray
The system cannot detect a flat tire.
Reasons for this can be:
>TPM is being reset
>Temporary interference due to systems
or devices which use the same radio fre-
quency
>Malfunction
Resetting system
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
Resetting finishes during driving, which can be
interrupted at any time. When driving resumes,
resetting is continued automatically.
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.Change to upper field if necessary. Turn the

the controller.
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.
The tires are shown in gray and "Resetting
TPM..." is displayed.
After a few minutes of driving, the set tire infla-
tion pressures in the tires are applied as the set
values to be monitored. Resetting finishes dur-

Technology for comfort, convenience and safety
86 ing driving. The tires are shown in green on the
Control Display.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.<
Message with low tire inflation
pressure
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
3.Repairing flat tire with M Mobility System,
refer to page217, or replace the damaged
wheel or wheels, refer to Changing wheels*
on page219.
The spare tire
* is equipped with the necessary
TPM electronics and is also monitored after
mounting and after resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheel is mounted without TPM elec-
tronics>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare*, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability. Please note that the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has
not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator lights up, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction

Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct if necessary, including on the
spare wheel
*: at least twice a month and before
starting long trips. Otherwise driving instability
or tire damage, and therefore accidents, can
result from incorrect tire inflation pressures. Do
not drive with a depressurized, i.e. flat, tire. A flat
tire will seriously impair your vehicle's handling
and braking response. Attempts to drive on a
flat tire can lead to a loss of control over the
vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page83, or reset the Tire Pressure Monitor,
refer to page85.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW center. tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. 100 mph/
160 km/h to achieve optimum driving comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages.
Otherwise tire damage and accidents could
occur.<
