Tyre
Pressure
Monitor
Principle
The
system
monitors
the
tyre
inflation
pressure in
the
four
tyres
installed
on
the
vehicle.
The
sysj
tem
warns
if
the
tyre
inflation
pressure
in
one
or
more
tyres
has
dropped.
General Sensors
in
the
tyre
valves
measure
the
tyre
inflajtion
pressure
and
tyre
temperature.
With
the
tyre
settings
in
iDrive,
the
system
candisplay
the
predefined
nominal
pressures
autojmatically
and
compare
them
with
the
current
tyreinflation
pressures.
If
the

which
are

ted
in
the
tyre
inflation
pressure
information
on
the
vehicle,
for
example
tyres
with
special
approj val,
the
system
must
be
actively
reset.
The
curj
rent
tyre
inflation
pressures
are
then
accepted
as the
specified
values.
When
operating
the
system,
please
also
comply
with
the
information
and
notes
in
the
chapter
on
tyre
inflation
pressure.
