Flat Tire Monitor FTM
Concept
The system detects tire inflation pressure
loss on the basis of rotation speed differen-
ces between the individual wheels while
driving.
In the event of a tire inflation pressure loss,
the diameter and therefore the rotational
speed of the corresponding wheel changes.
The difference will be detected and reported
as a flat tire.
The system does not measure the actual in-
flation pressure in the tires.
Functional requirements
The following conditions must be met for
the system; otherwise, reliable flagging of a
loss of tire inflation pressure is not assured:
– After a tire or wheel replacement, an ini-
tialization was performed with the cor-
rect tire inflation pressure.
– After the tire pressure was adjusted to a
new value, an initialization was per-
formed.
Status display
The current status of the flat tire monitor
can be displayed, for instance whether the
RPA is active.
Via the Central Information Display (CID):
1. "My MINI"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initialization required
An initialization must be performed in the
following situations:
– After the tire inflation pressure has
been adjusted.
– After a tire or wheel replacement.
Performing initialization
When initializing, the set tire inflation
pressures serve as reference values in order
to detect a flat tire. Initialization is started
by confirming the tire inflation pressures.
Do not initialize the system when driving
with snow chains.
Via the Central Information Display (CID):
1. "My MINI"
2. "Vehicle status"
3. "Flat Tire Monitor"
4. Switch on drive-ready state and do not
drive off.
5. Start the initialization with: "Perform
reset".
6. Drive away.
The initialization is completed while driv-
ing, which can be interrupted at any time.
The initialization automatically continues
when driving resumes.
Messages
General information
When a flat tire is indicated, DSC Dynamic
Stability Control is switched on, if needed.
Safety information
Warning
A damaged regular tire with low or miss-
ing tire inflation pressure impacts han-
dling, such as steering and braking re-
sponse. Run-flat tires can maintain limited
stability. There is a risk of accident. Do not
continue driving if the vehicle is equipped
with normal tires. Follow the information
