Flat Tire Monitor - BMW MINI Owner's Manual

FLAT TIRE MONITOR

The concept
As you drive, the Flat Tire Monitor keeps
track of the tire inflation pressure in all four
tires. The system alerts you when there is a
substantial pressure loss in one of the tires
relative to another.
In the event of tire pressure loss, the rolling
radius of the tire changes, thereby affect-
ing the rotational speed of the wheels. This
change is detected, and a flat tire warning
is issued to the driver.
System requirements
To ensure the reliability of flat tire warn-
ings, the system must be initialized with
the correct tire inflation pressures.
Each time you correct the pressure in
a tire, or change a wheel or tire, the
system must be reinitialized.<

System limitations
The Flat Tire Monitor cannot alert you
to severe and sudden tire damage
caused by external factors, nor does it
detect the gradual and minor loss of pres-
sure in all four tires.<
The system could issue a false warning or
function in a delayed manner in the follow-
ing situations:
>System was not initialized
>You are driving on a snow-covered or
slippery road surface
>Sporty driving style: slip at the drive
wheels, high lateral acceleration
>You are driving with snow chains.
When driving with a space-saver spare tire,
the Flat Tire Monitor cannot function.

Initializing the system
Initialization is completed while you
are driving, but you can stop the car
at any time. Initialization is automatically
continued when you continue driving. Do
not initialize the system if you are driving
with snow chains or a space-saver spare
tire.<
1. Before a journey, start the engine, but do
not start driving.
2. Press the button until the indicator lamp
in the display elements lights up in yel-
low for several seconds.
3. Drive off.
Initialization is completed during the
drive, without any feedback issued.
