Depending on  the  driving  situation  and  your
 vehicle's  equipment,  the  system  
may

 
advise
 
you
 
to
 
skip

the

of

remain
 
determining

 
factors
 
when

the
 
best

 
gear
.  
Therefore,
 
the
 
driver
 
remains
 
responsible

 
for
 
deciding
 
whether

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

 
system
 
triggers
 
an
 
alert
 
if
 
a
 
drop
 
in

 
pressure
 
is
 
detected
 
in
 
one
 
or
 
more
 
tyres. This

 
system
 
does
 
not
 
avoid
 
the
 
need

 
to
 
check
 
the
 
tyre
 
pressures
 
regularly

 
(including
 
the
 
spare
 
wheel)

  and   before   a   long   journey.
Driving  
with
 
under-inflated
 
tyres

,  
particularly

 
under
 
arduous
 
con
-
ditions  
(vehicle
 
loaded,
 
high
 speed,
  long   journey).
Driving  
with
 
under-inflated
 
tyres
 
increases

  fuel   consumption.The tyre pressures for your vehi-
cle
 
can
 
be
 
found
 
on
 
the
 
tyre
 
pres
-
sure  
label
 
(see
 
the
 
"Identification
 
markings"

  section).
The  
tyre
 
pressures
 
must
 
be
 
checked

 
when
 
the
 
tyres
 
cold
 
(vehicle

ter  
driving
 
for

Otherwise,

spot
 
angle
 
of
 
their
 
vehicle

 
(areas
 
masked
 
from
 
the

field

 
of
 
vision),
