2014.5 Citroen C4 CACTUS RHD four wheel drive

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.
See
  the   "Identification   markings"  
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.

Under-inflation alertReinitialisation
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   detection   system  
d

oes   not   give   a   warning   if   a   pressure   is  
i

ncorrect   at   the   time   of   reinitialisation.
This
 
is
 
given
 
by
 
fixed
 
illumination
 
of

lamp,
 
accompanied
 
by
 
a

n
 
audible
 
signal
 
and
 
the
 
display
 
of
 
a

It
 
is
 
necessary   to   reinitialise   the   system   every  
t

ime
 
one   or   more   tyre   pressure   is   adjusted,   and  
a

fter
 
changing   one   or   more   wheels.
A
 
label   attached   to   the   middle   pillar,   driver's

gives   a   reminder   of   this.
