A change in the tire inflation pressure during
driving is taken into account.
A correction is only necessary if this is indicated
by the TPM
Wheels, green

tem is being reset.
Wheels, gray
The system cannot detect a flat tire. Reasons for
this may be:
▷TPM is being reset.▷Disturbance by systems or devices with the
same radio frequency.▷Malfunction.
For Canadian models: additional
information
The status display additionally shows the cur‐
rent tire inflation pressures and tire tempera‐
tures.
When correcting the tire inflation pressures,
note the following:
The tire pressure increases as the tire temper‐
ature increases.
Therefore, only correct the tire inflation pres‐
sure when the tire is at the ambient temperature.
Compare the displayed tire temperature with
the external temperature in the instrument clus‐
ter.
Resetting the system
Reset the system after each correction of the
tire inflation pressure and after every tire or
wheel change.1."Vehicle Info"2."Vehicle status"3. "Reset"4.Start the engine - do not drive away.5.Reset the tire pressure using "Reset".6.Drive away.
The tires are shown in gray and "Resetting

After driving for a few minutes, the set tire infla‐
tion pressures are applied as set values. The re‐
setting process is completed automatically dur‐
ing driving. The tires are shown in green and
"TPM active" is shown on the Control Display.
The trip can be interrupted at any time. If you
drive away again, the process resumes auto‐
matically.
If a flat tire is detected during a reset, all tires are
displayed in yellow.

Message when the system was not
reset
A Check Control message is displayed.
The system detected a wheel change but was
not reset.
Warnings regarding the current tire inflation
pressure are not reliable.

system.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check

have the service center check it if necessary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the sys‐
tem again.▷Disturbance by systems or devices with the
same radio frequency: after leaving the area
of the disturbance, the system automatically
becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended 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 inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one
or more of your tires is significantly under-in‐
flated. 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
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation 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 sub‐
stitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also been
equipped with a TPMS malfunction indicator to
indicate when the system is not operating prop‐
erly. The TPMS malfunction indicator is com‐
bined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then re‐
main continuously illuminated. This sequence
will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the mal‐
function 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 re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.Seite 98ControlsSafety98
Online Edition for Part no. 01 40 2 903 329 - 07 12 490
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀
A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion pressure regularly.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive wheels,
high lateral acceleration.▷When 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 inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming 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 with "Reset".6.Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 181, are labeled
with a circular symbol containing the letters
RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.

The concept
The parked-car ventilation ventilates the vehicle
interior and lowers its temperature, if necessary.

or by using two preset switch-on times. It re‐
mains switched on for 30 minutes.
Operation can be performed via iDrive.
