It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.
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; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐ tion of the tire inflation pressure and afterevery 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
cannot be detected. Therefore, check the tire
inflation 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.
When driving with a compact wheel, the Flat
Tire Monitor is unable to function.
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 or with a compact wheel.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 warning lamp lights up red. A
message appears on the Control Dis‐
play. In addition, a signal sounds.
There is a flat tire or a major loss in tire inflation
pressure.
Reduce your speed and stop cautiously. Avoid
sudden braking and steering maneuvers.
Do not continue driving without run-flat
tires
If the vehicle is not equipped with run-flat tires
as provided at the factory, do not continue
driving. Continuing to drive could cause severe
accidents.◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.

Deactivating DSC
Press and hold the button, but not longer than
approx. 10 seconds, until the indicator lamp for
DSC lights up in the instrument cluster and
DSC OFF is displayed. DTC Dynamic Traction
Control and DSC are deactivated together.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
Activating DSC
Press the button.
DSC OFF and the indicator lamp in the instru‐
ment cluster go out.
For better control The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC and
DTC has failed.
DSC deactivated: The indicator lamp lights up and
DSC OFF appears in the instrument
cluster.
DSC and DTC deactivated.
Dynamic Traction Control
DTC
The concept The DTC system is a version of the DSC in
which forward momentum is optimized.
The system ensures maximum forward mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:
▷When driving in sand, on snowy inclines, in
slush, or on unplowed, snow-covered road
surfaces▷When rocking a vehicle free or starting off
in deep snow, sand, or on loose ground▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.

The support of the sidewall allows the tire to
remain drivable to a restricted degree in the
event of a pressure loss.
Driving with a damaged tire:▷Flat Tire Monitor FTM, refer to page  97▷Tire Pressure Monitor TPM, refer to
page  99
Snow chains
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your service center for
more information.
BMW X5: use only in pairs on the rear wheels,
equipped with tires of the following size:
▷255/55 R 18▷255/50 R 19
BMW X6: use only in pairs on rear wheels of
size 255/50 R 19.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h when using snow chains.
Do not initialize the Flat Tire Monitor if snow
chains are mounted; otherwise, the instrument
might issue an incorrect reading.
When driving with snow chains, it can be bene‐
ficial to temporarily activate DTC, refer to
page  106.
