Operating fault
The aler t  is  given  by  the  fixed  illumination o

 e

quipment,   the   display   of   a   message.

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

heel   (according   to   equipment).
Go   to   a   CITROËN   dealer   or   a   qualified  w
orkshop to   have   the   system   checked   or,  
f

ollowing   the   repair   of   a   puncture,   to   have   the  
o

riginal   wheel,   equipped   with   a   sensor,   refitted.
Any
  tyre   repair   or   replacement   on   a   wheel  
f

itted   with   this   system   must   be   carried   out   by   a  
C

ITROËN   dealer   or   a   qualified   workshop.
If
  after   changing   a   tyre,   a   wheel   is   not   detected  
b

y   your   vehicle   (fitting   snow   tyres   for   example),  
y

ou   must   have   the   system   reinitialised   by   a  
C

ITROËN   dealer   or   a   qualified   workshop.
The loss of pressure detected does not
always
  lead   to   visible   deformation   of   the  
t

yre.   Do   not   rely   on   just   a   visual   check.This alert is also displayed when one or
more
  wheels   is   not   fitted   with   a   sensor  
(

for   example,   a   space-saver   or   steel

The   alert   is   maintained   until   the   tyre   or  t
yres concerned is reinflated, repaired
or
  replaced.
The
  spare   wheel   (space-saver   type   or   a
