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.

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,

wheels.

The under-inflation alert can only be considered   reliable   if   reinitialisation   of  
t

he   system   is   done   with   the   the   four   tyre  
p

ressures   correctly   set.
Snow chains
The system does not have to be reinitialised   after   fitting   or   removing  
sn

ow
 c
hains.
Operating fault
The flashing and then fixed illumination of   the   under-inflation   warning   lamp i

ndicates   a   fault   with   the   system.
In
 
this
 
case,   under-inflation   monitoring   of   the  
t

yres
 
is
 
no   longer   assured.
Have
 
the
 
system   checked   by   a   CITROËN  
d

ealer
 
or
 
a   qualified   workshop.
Before
  doing   anything   to   the   system,  
t

he
  pressures   of   the   four   tyres   must   be

Other lamps are provided to meet the requirements   of   particular   driving   conditions:
-
 
a
  rear   foglamp,
-
 
d

d

uring   the   day. In
  some   weather   conditions   (e.g.   low  
t

emperature   or   humidity),   the   presence  
o

g

lass   of   the   headlamps   and   rear   lamps

h

ave   been   on   for   a   few   minutes.Travelling abroad
If using your vehicle in a country that d
rives   on   the   other   side   of   the   road,   the  
h

eadlamps   must   be   adjusted   to   avoid  
d

azzling   on-coming   drivers.
