Runflat indicator RPA
Principle
The system identifies a loss of tyre inflation
pressure by comparing the rotational speeds
of the individual wheels during the journey.
If a tyre loses inflation pressure, its diame-
ter changes. This in turn alters the rota-
tional speed of the corresponding wheel.
The difference will be detected and reported
as a flat tyre.
The system does not measure the tyre infla-
tion pressure as such.
Operating requirements
The following requirements must be met for
the system, otherwise reliable signalling of
a loss of tyre inflation pressure is not en-
sured:
– After every tyre or wheel change, an ini-
tialisation must be carried out with the
correct tyre inflation pressure.
– An initialisation must be carried out af-
ter the tyre inflation pressure has been
adjusted to a new value.
Status display
It is possible to display the current status of
the runflat indicator, for example to check
whether the RPA is active.
Using the on-board monitor:
1. "My MINI"
2. "Vehicle status"
3. "Flat Tyre Monitor"
The status is displayed.
Initialisation required
An initialisation must be performed in the
following situations:
– After adjusting the tyre inflation pres-
sure.
– After a tyre or wheel change.
Performing an initialisation
On initialisation, the current tyre pressures
are saved as a reference for detection of a
flat tyre. The initialisation is started by con-
firming the correct tyre inflation pressures.
When driving with snow chains fitted, do
not initialise the system.
Using the on-board monitor:
1. "My MINI"
2. "Vehicle status"
3. "Flat Tyre Monitor"
4. Start the engine but do not drive off.
5. Start the initialisation: "Perform reset".
6. Drive off.
Initialising is completed during the journey;
this process can be interrupted at any time.
Initialising resumes automatically when you
continue your journey.
Messages
General
Dynamic Stability Control DSC is activated
if necessary as soon as the message for a
flat tyre appears.
Safety note
WARNING
A damaged normal tyre with too little or
no tyre inflation pressure impairs driving
properties, for example steering and brak-
ing. Tyres with run-flat properties allow a
limited level of stability to be maintained.
There is a danger of accidents. Do not con-
tinue driving if the vehicle is fitted with
