FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor detects a pressure loss in
one tire by comparing the speeds of the individ-
ual wheels during driving.
In the event of a pressure loss, there is a change
in the rolling circumference and therefore the
rotation speed of the corresponding wheel. The
system detects this change and reports it as a
flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate sudden
severe tire damage caused by outside factors
and does not detect a natural, even pressure
drop in all four tires.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains
*. button in the center console:
1.Start the engine, but do not start driving.
2.Press the button for approx. 5 seconds.
After the button is released, the warning
lamp lights up in yellow for several sec-
onds in the instrument cluster, refer to
Indication of a flat tire. The message "Initial-
izing FTM ..." appears on the Control Dis-
play for a few seconds.
3.Start to drive.
The initialization finishes during driving
without feedback.
Via 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.Turn the controller until "Settings" is
selected and press the controller.
4.Select "Vehicle / Tires" and press the con-
troller.

After changing wheels/tires
After changing tires or wheels, the slip detec-
tion of the Sequential Manual Transmission
must become familiar with the changed state.
Reinitialize the system for this purpose:
1.Move the selector lever into the idling
position N on a straight stretch of road at a
speed between 20 mph/30 km/h and
90 mph/150 km/h.
2.Pull both shift paddles for approx. 2 sec-
onds.
If you do not carry out initialization, the system
will automatically learn the changed state grad-
ually during driving. This may be noticeable
from the clutch opening and closing briefly.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permitted in pairs, with winter tires
of the size 245/45 R 18 on the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.Make sure that the snow chains are always suf-
ficiently tensioned. Readjust tension in accor-
dance with the chain manufacturer's specifica-
tions if necessary.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
After mounting or removing snow chains, the
slip detection of the Sequential Manual Trans-
mission must become familiar with the altered
state. To do this, reinitialize the system, refer to
After changing wheels/tires.<
