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
The initialization process adopts the set infla-
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.
Do not initialize the system when driving with
snow chains.
1."Vehicle Info"
2."Vehicle status"3."Reset"
4.Start the engine – do not drive away.
5.Start the initialization by selecting "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, a signal
sounds. There is a flat tire or a major
loss in tire pressure.
1.Reduce speed and stop the vehicle with
caution. Avoid sudden braking and steering
maneuvers.
If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents.<
When a flat tire is reported, the Dynamic Stabil-
ity Control DSC is activated.
Actions in the event 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.
When driving 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 inflation
pressure in all four tires.

Status indicator on the Control Display
The color of the tires represents the status of
the tires and the system.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only required when this is indi-
cated by the TPM.
Green wheels
The inflation pressure corresponds to the
desired state.
"TPM active" appears in 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 thus issues a warning based on
the inflation pressures initialized last.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
>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"
4.Start the engine – do not drive away.
5.Reset the inflation pressure by selecting
"Reset".
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 process
is completed automatically as you drive. On the
Control Display, the wheels are shown in green
and "Status: TPM active" is displayed.
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
If a flat tire is detected while the system is
resetting, all tires on the Control Display
are displayed in yellow. The message "Low
tire!" is displayed.<
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
>There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
>The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressures initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers.
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.

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 underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle’s han-
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underin-
flation has not reached the level at which the
TPMS low tire pressure telltale illuminates.
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 lit. This sequence will continue
upon subsequent vehicle startups as long as
the malfunction exists. When the malfunction
indicator is illuminated, 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
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Active steering*
The concept
Active steering varies the turning angle of the
front wheels in relation to steering wheel move-
ments. It also varies the steering force required
to turn the wheels depending on the speed at
which you are driving.
When you are driving in the low speed range,
e.g. in a town or when parking, the steering
angle is increased, i.e. steering becomes very
direct and less effort is required to turn the
wheels. In the higher speed range, on the other
hand, the steering angle is reduced as the
speed increases. This improves the handling of
your BMW over the entire speed range.
In critical situations, the system can make tar-
geted corrections to the steering angle pro-
vided by the driver and thus stabilize the vehicle
before the driver intervenes. This stabilizing
intervention is simultaneously deactivated
when DSC is switched off, refer to page83.
Malfunction
The warning lamps come on. Active
steering is malfunctioning or is tem-
porarily deactivated. At low speeds,
greater steering wheel movements
are required, whereas at higher speeds the
vehicle reacts more sensitively to steering
wheel movements. The stability-enhancing
feature may also be deactivated. Drive cau-
tiously and think well ahead.
Deactivation
Active steering is deactivated to perform an ini-
tialization. A message indicates that the feature
is deactivated. Initialization may take several
minutes.
If the message does not disappear during the
current trip, have the system checked.
Defect
If there is a defect, a corresponding text mes-
sage appears. Have the system checked.
