Technology for driving comfort and safety CONTROLS
85
Vibrations or loud noises while driving can
indicate final failure of the tire. Reduce
your speed and bring the vehicle to a stop;
otherwise, pieces of tire may come off, which
could result in an accident. Do not continue
driving and contact your MINI dealer.<
Tire Pressure Monitor
TPM
The concept
Measuring the inflation pressure in the four
mounted tires. The system notifies you if there is
a significant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system again after each correction of
the tire inflation pressure and after every tire or
wheel change.
System limitations
Sudden, serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pressures.
The system is inactive and cannot indicate a flat
tire:
> If a wheel without TPM electronics, e.g. a
compact spare wheel, is mounted.
> Interference with TPM by other systems
or devices with the same transmission
frequency.
Status display
The current status of the Tire Pressure Monitor
can be displayed by the onboard computer, e.g.
whether or not the TPM is activated.
1. "Vehicle Info"
2. "Vehicle status"
3. "Tire Pressure Monitor - TPM"
The status is displayed.
Status indicator on the onboard
computer
The tire and system condition is indicated by the
color of the tires.
A change in the tire inflation pressure during
driving is taken into account.
A correction is only required when this is
indicated by the TPM.
Green wheels
The inflation pressure corresponds to the
desired state.
"TPM active" is displayed on the onboard
computer.
Gray wheels
The system cannot detect a puncture.
Reasons for this may be:
> TPM is being reset.
> Interference from systems or devices with
the same transmission frequency.
> Malfunction.
