TYRE UNDER-INFLATION DETECTION
System which automatically  checks  the  pressures
  of   the   tyres   while   driving.
The
 
system
 
continuously
 
monitors
 
the
 
pressures of the four tyres, as soon as
the

  vehicle   is   moving.
A
 pressure

 
sensor
 
is
 
located
 
in
 
the
 
valve

 
of
 
each
 
tyre
 
(except
 
the
 
spare
 
wheel).
The

alert
 
if
 
a
 
drop
 
in

 
pressure
 
is
 
detected
 
in
 
one
 
or
 
more
 
tyres. This

 
system
 
does
 
not
 
avoid
 
the
 
need

the
