The aler t  is  given  by  the  fixed  illumination o

 e

quipment,   the   display   of   a   message.
Under-inflation alert

F
I
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  
a

lways   lead   to   visible   deformation   of   the  
t

yre.   Do   not   rely   on   just   a   visual   check.This
  alert   is   also   displayed   when   one   or  
m

ore   wheels   is   not   fitted   with   a   sensor  
(

for   example,   a   space-saver   or   steel  
spar

e
 w
heel).
The   alert   is   maintained   until   the   tyre   or  t
yres   concerned   is   reinflated,   repaired  
o

r   replaced.
The
  spare   wheel   (space-saver   type   or   a  
s

teel   rim)   does   not   have   a   sensor.

Maintenance
In the event of a malfunction with the system, the "ECO OFF"   switch   warning   lamp   flashes,  
t

hen   comes   on   continuously.
Ha

ve   it   checked   by   a   CITROËN   dealer   or   a

orkshop.
Operating fault
This system requires a specific battery with   a   special   specification   and   technology  
(

reference numbers   available   from   a   CITROËN  
d

ealer   or   a   qualified   workshop).
Fitting
  a   battery   not   listed   by   CITROËN  
i

ntroduces   the   risk   of   malfunction   of   the  
s

ystem. Before
  doing   anything   under   the  
b

onnet,   deactivate   the   Stop   &   Start  
s

ystem   to   avoid   any   risk   of   injury  
r

esulting   from   automatic   operation   of  
S

TART   mode.
The   Stop   &   Start   system   makes   use  
o

f   advanced   technology.   All   work   on  
t

his   type   of   battery   must   be   done   only  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
In
 
the
 
event
 
of
 
a
 
fault
 
in
