Flat Tire Monitor FTM*
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a tire pressure loss due to
speed comparisons among the individual
wheels as you drive.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. The system detects this
and reports it as a flat tire.
Functional requirement
The system has to have been initialized at the
correct inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system will not detect a natural, uniform
pressure loss in all four tires. Therefore you
should check the inflation pressure regularly.
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
>Driving with snow chains
*
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.
whether or not the FTM is active.
1."Vehicle Info"
2."Vehicle status"3."Flat Tire Monitor"
The status is displayed.
Initialization
In the initialization, the set inflation pressures
are adopted as reference values for the detec-
tion of a flat tire. The initialization is begun by
confirmation of the inflation pressures.
Do not initialize the system while snow chains
are attached.
1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine – do not drive away.
5.Start the initialization using "Reset".
6.Start driving.
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<

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.
What to do in case of a flat tire
Run-flat tires
With a damaged tire, is possible to continue
driving at speeds of up to 50 mph/80 km/h.
Do not continue driving if the vehicle is
not equipped with run-flat tires, refer to
page223; continued driving could result in a
severe accident.<
When continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu-
vers.
2.Do not exceed a speed of 50 mph/80 km/h.
3.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.<
Possible travel distance with complete tire
pressure loss:
>With a light load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or 4 persons
without luggage:
Approx. 94 miles/150 km
>With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km
Drive cautiously and do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change, e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. may indicate the final failure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident.
Do not continue driving; instead, contact your
BMW center.<
Tire Pressure Monitor TPM*
The concept
Check the inflation pressure in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system has to have been reset at the cor-
rect inflation pressure; otherwise, a reliable
reporting of a flat tire is not assured.
Always use wheels with TPM electronics to
assure a trouble-free function of the system.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
It is impossible to provide advance warn-
ing of sudden, severe tire damage caused
by outside influences.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
>when a wheel without TPM electronics is
installed.
>when other systems or devices that use the
same radio frequency interfere with TPM.

Status display
The current status of the TPM Tire Pressure
Monitor can be displayed on the Control Dis-
play, e.g. whether or not the TPM is active.
1."Vehicle Info"
2."Vehicle status"
3."Tire Pressure Monitor - TPM"
The status is displayed.
Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
A change in the inflation pressure during driving
is taken into account.
A correction is only needed if TPM indicates it.
Green
The inflation pressure corresponds to the
desired state.
"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.
All wheels yellow
>There is a flat tire or substantial loss of tire
pressure in several tires.
>The system was not reset after a wheel
change and will thus issue warnings at the
last initialized inflation pressures.
Gray
The system cannot detect a puncture.
The reasons for this are as follows:
>TPM is being reset.
>Interference from systems or devices that
use the same radio frequency.
>Malfunction.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
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 driving.
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 resetting is com-
pleted automatically as you drive. On the Con-
trol Display, the tires are shown in green and
"Status: TPM active" is displayed again.
You can stop driving at any time. The resetting
continues automatically when you resume driv-
ing.
If a flat tire is detected during the reset-
ting process, all tires are displayed in
yellow in the Control Display. The message
"Low tire!" is shown.<

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 underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should

Information for your safety
It is not merely the tires' service life, but also
driving comfort and, to a great extent, driving
safety that depend on the condition of the tires
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly
and correct it, if necessary: at least twice a
month and before starting long trips. If you fail
to observe this precaution you may be driving
on tires with incorrect tire pressures, a condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive
with deflated, i.e. flat tires, except when using
run-flat tires. A flat tire will seriously impair your
vehicle's handling and braking response.
Attempts to drive on a flat tire can lead to loss of
control over the vehicle.<
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 is higher.
After correcting the tire inflation pressure,
reset the Tire Pressure Monitor, refer to
page90, or reinitialize the Flat Tire Monitor,
refer to page88.<
Inflation 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 approved and tire brands recom-
mended by BMW; a list of these is available
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up
to 100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h
and to achieve optimum driving comfort, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of
100 mph or 160 km/h.
These tire inflation pressures can also be found
on the driver's side door post when the driver's
door is open.
The maximum permissible speed for
these tire pressures is 100 mph or
160 km/h. Do not exceed this speed; otherwise,
tire damage and accidents could occur.<
Tire inflation pressures for driving
above 100 mph or 160 km/h
In order to drive at maximum speeds in
excess of 100 mph or 160 km/h, adjust
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those
exceeding 100 mph or 160 km/h. Otherwise,
tire damage and accidents could occur.<
Observe all national and local maximum speed
limits; otherwise, violations of the laws could
occur.
