Tire
pressure
monitor
Concept The
system
monitors
tire
inflation
pressure
in
thefour
mounted
tires.
The
system
warns
you
if there
is
a
loss
of
pressure
in
one
or
more
tires.
General
information Sensors
in
the
tire
valves
measure
the
tire
infla#jtion
pressure
and
tire
temperature.
Using
the
tire
settings
in
iDrive,
the
system
can
automatically
display
the
specified
target
pres#j sures
and
compare
them
with
the
actual
tire
in#j
flation
pressures.
If
tires
are
being
used
that
are
not
specified
on the
tire
inflation
pressure
details
on
the
vehicle,
such
as
tires
with
special
approval,
the
system
needs
to
be
actively
reset.
The
system
will
then
take
over
the
actual
tire
inflation
pressures
as
the target
pressures.
When
operating
the
system,
also
note
the

found
in
