RPA
Principle
The
system
identifies
a
loss
of
tyre
inflation
presj
sure
by
comparing
the
rotational
speeds
of
the
individual
wheels
during
the
journey.
If
a
tyre
loses
inflation
pressure,
its
diameter
changes.
This
in
turn
alters
the
rotational
speed of
the
corresponding
wheel.
The
difference
will
be
detected
and
reported
as
a
flat
tyre.
The
system
does
not
measure
the
tyre
inflation
pressure
as
such.

Wheel
change
General
For
run-flat
tyres
or
when
using
a
flat
tyre
kit,
it
is
not
always
necessary
to
change
a
wheel
immedij ately
if
tyre
inflation
pressure
is
lost
due
to
a
flattyre.
If
required,
the
tools
for
changing
wheels
are available
as
optional
accessories
from
a
Service
Partner
of
the
manufacturer,
another
qualified
Service

the
vehicle briefly
during
a
wheel
change.
Even
if
the
safety
measures
are
complied
with,
there
is
a
risk
of the
raised
vehicle
falling
over
due
