Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This   system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving   with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  p
articularly   under   arduous   condition  (
high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
For   more   information   on   the  
i

dentification   markings,   refer   to   the  c
orresponding s ection.
Tyre   pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

top the vehicle as soon as it is safe to
do so.
The
  loss   of   pressure   detected   does   not  
a

F
 
I

f
 
you
  have   a   compressor   (such   as   the   one  
i

n
 
the
  temporary   puncture   repair   kit)   check  
t

he
 
pressures   of   the   four   tyres   when   cold.
 I

f
 
it
 
is
  not   possible   to   carry   out   this   check  
s

traight   away,   drive   carefully   at   reduced  
s

peed.

F

I

n the event of a puncture, use the
temporary
  puncture   repair   kit   or   the   spare  
w

heel   (depending   on   equipment).
The
  alert   is   maintained   until   the   system  
i

s
 r

einitialised.
Reinitialisation
Before reinitialising the system, ensure t hat the pressures of the four tyres are
correct
  for   the   use   of   the   vehicle   and   in  
l

ine   with   the   recommendations   on   the  
t

yre   pressure   label.
The
  under-inflation   alert   can   only   be  
r

elied   on   if   the   reinitialisation   of   the  
s

ystem   has   done   with   the   pressures   in  
t

he   four   tyres   correctly   adjusted.
The
  under-inflation   detection   system  
d

oes   not   give   a   warning   if   a   pressure   is  
i

ncorrect   at   the   time   of   reinitialisation.
It
 
is
 
necessary
 
to
 
reinitialise
 
the
 
system
 
every
 
t

ime
 
one
 
or
 
more
 
tyre
 
pressures
 
are
 
adjusted,
 
a

nd
 
after
 
changing
 
one
 
or
 
more
 
wheels.
A
 
label
 
attached
 
to
 
the
 
middle
 
pillar,

ide,
 
gives
 
a
 
reminder
 
of
 
this.

General recommendations
Observe the legislation in force in your co unt r y.
Ensure
  that   the   weight   of   the   towing  
v

ehicle   is   higher   than   that   of   the   towed  
v

ehicle.
The
  driver   must   remain   at   the   wheel   of  
t

he   towed   vehicle   and   must   have   a   valid  
d

riving
 l
icence.
When
  towing   a   vehicle   with   all   four  
w

heels   on   the   ground,   always   use   an  
a

pproved   towing   arm;   rope   and   straps  
ar

e
 p
rohibited.
The
  towing   vehicle   must   move   off   gently.
When
  towing   a   vehicle   with   the   engine  
o

ff,   there   is   no   longer   any   power  
a

ssistance   for   braking   or   steering.
In
  the   following   cases,   you   must   always

-
 w
