Functional requirement
The LED in the button goes out.
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
The selection of the chassis and suspension
tuning setting is stored for the remote control
currently in use.
The initialization must be repeated after
each time the tire inflation pressure is cor-
rected and after every tire or wheel change.<
Self-leveling suspension*
System limits
Malfunction
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.<
The warning lamp for self-leveling
suspension lights up yellow and a
message is shown on the Control
Display. A malfunction has occurred in the self-
leveling suspension. Stop and check the vehi-
cle. If it is considerably lower at the rear than at
the front, and possibly also on one side – rear
left compared to rear right –, proceed to the
nearest BMW Sports Activity Vehicle Center or
a workshop that works according to BMW
repair procedures with correspondingly trained
personnel. Drive with appropriate caution in the
meantime. The vehicle has reduced ground
clearance and driving comfort may be notice-
ably reduced. Even if the orientation of the vehi-
cle is normal, when a malfunction is indicated
on the display, you should proceed to the near-
est BMW Sports Activity Vehicle Center or a
workshop that works according to BMW guide-
lines and uses appropriately trained personnel.
In the following situations, the system could be
delayed or malfunction:
>
>
>
System has not been initialized
Driving on snowy or slippery road surface
Sporty driving style: slip in the drive wheels,
high lateral acceleration
>
Driving with snow chains*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically. Do not initialize the sys-
tem when driving with snow chains* or with the
compact wheel*.<

The concept
1.
Press the
button.
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
This opens the start menu.
2.
3.
4.
Press the controller to open the menu.
Select "Settings" and press the controller.
Select "Vehicle / Tires" and press the con-
troller.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
