The flashing and then fixed illumination   of   the   under-inflation w

arning   lamp   accompanied   by   the
 i

llumination   of   the   service   warning
 l

amp   indicates   a   fault   with   the   system.
Operating fault
The aler t  is  given  by  the  fixed  illumination o
f   this   warning   lamp,   accompanied   by a

n   audible   signal,   and   depending   on
 e

quipment,   the   display   of   a   message.
Under-inflation alert
In the event of a problem on one of the tyres, the   symbol   or   the   message   appears,   according  
t

o   equipment,   to   identify   it.
F
 
R
educe   speed,   avoid   sudden   steering  
m

ovements   or   harsh   brake   applications.
F
 
S
top   as   soon   as   it   is   safe   to   do   so. In
  this   case,   monitoring   of   the   tyre   pressures   is  
n

ot   assured.
F  
I
f   you   have   a   compressor   (the   one   in   the  
t

emporary   puncture   repair   kit   for   example),  
c

heck   the   four   tyre   pressures   when   cold.
 I

f   it   is   not   possible   to   check   the   tyre  
p

ressures   at   the   time,   drive   carefully   at  
r

educed
 s
peed.


or
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.
Driving

262
F If  the   warning   lamp   and   the  S
TOP  warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   is   recommended.
Ty r e s
F Check   the   tyre   pressures   of   the  
towing   vehicle   and   of   the   trailer,   observing  
t

he
 re
commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   
c
oolant  
t

emperature.
