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 alert is given by the fixed illumination   of   this   warning   lamp,  
a

ccompanied   by   an   audible   signal,  
a

nd   depending   on   equipment,   the  
d

isplay   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.

  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

 I

f   it   is   not   possible   to   check   the   tyre  
p

ressures   at   the   time,   drive   carefully   at  
r

educed

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
always
  lead   to   visible   deformation   of  
t

he   tyre.
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  
spar

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

teel   rim)   does   not   have   a   sensor.

Temporarily exceeding the
programmed speed
When descending a steep hill, the cruise   control   system   cannot   prevent  
t

he   vehicle   from   exceeding   the  
pro

grammed
 s
peed.
When
  required   (overtaking   manoeuvre...),   it   is  
p

ossible   to   exceed   the   programmed   speed   by  
p

ressing   the   accelerator   pedal.
The
 
cruise   control   is   temporarily   overridden  
a

nd
 
the   programmed   speed   setting   flashes.
Only use the cruise control if the traffic
conditions will allow you to drive for a
certain   time   at   a   steady   speed   and   at   a  
s

afe   distance   from   the   vehicle   ahead.
Do not activate the cruise control in
urban   areas,   in   heavy   traffic,   on   winding  
o

r steep roads, on slippery or flooded
roads, or in conditions of poor visibility
(heavy   rain,   fog,   falling   snow...).
In   some   circumstances,   it   may   not  
b

e   possible   to   maintain   or   reach   the  
p

rogrammed   speed:   towing,   vehicle  
h

eavily   loaded,   steep   climb.
The   use   of   mats   not   approved   by  
C

ITROËN   may   inter fere   with   the  
o

peration   of   the   cruise   control.
To   avoid   any   risk   of   jamming   of   the  
ped

als:
-  e nsure   that   the   mat   is   positioned  c
o r r e c t l y,
-
 
n
ever   fit   one   mat   on   top   of   another.
To
 
return   to   the   programmed   speed,   simply  
r

elease   the   accelerator   pedal.
Once the vehicle has returned to the
programmed   speed,   the   cruise   control   takes  
ov

er
 
again:   the   display   of   the   programmed  
s

peed
  setting   becomes   steady   again.You   may   have   to   brake   to   control   the   speed   of  
y

our   vehicle.   In   this   case,   the   cruise   control   is  
au

tomatically
 p
aused.
To   activate   the   system   again,   press   button   4
.
Switching off
F Turn wheel 1 to the "0"  position:   the   cruise  c
ontrol   information   disappears   from   the  
sc

reen.
Operating fault
Flashing dashes indicate a fault with the cruise control   system.
Have
  it   checked   by   a   CITROËN   dealer   or   a  
q

orkshop.

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.
Advice on installation
F If   you   have   to   fit   the   chains   during   a  j
ourney,   stop   the   vehicle   on   a   flat   sur face  
o

n   the   side   of   the   road.
F
 
A

v

ehicle.

p

rovided   by   the   manufacturer.
F
 
M
ove   off   gently   and   drive   for   a   few  
m

oments,   without   exceeding   30   mph  
(50
  km/h).
F
 
S

For more information on snow chains, contact a C ITROËN   dealer   or   a   qualified   workshop.It
  is   strongly   recommended   that   before  y
ou   leave,   you   practise   fitting   the   snow  
c

hains   on   a   level   and   dry   sur face.
The
 
snow
 
chains
 
must
 
be

They
 
must
 
never
 
b

e fitted to "space-saver" type spare
wheels.
Take  account   of   the   legislation   in   force  
i

n your country on the use of snow
chains
  and   the   maximum   running   speed  
a

uthorised. Avoid
  driving   with   snow   chains   on   roads  
t

hat have been cleared of snow, to
avoid
  damaging   your   vehicle's   tyres   and  
t

he   road   sur face.   If   your   vehicle   is   fitted  
w

ith   alloy   wheels,   check   that   no   part   of  
t

he   chain   or   its   fixings   is   in   contact   with  
t

he   wheel   rim.
