Depending on the driving situation and your vehicle's   equipment,   the   system   may   advise  
y

ou   to   skip   one   (or   more)   gear(s).   You   can  
f

ollow   this   instruction   without   engaging   the  
i

ntermediate
 g
ears.
The
  gear   engagement   recommendations   must  
n

ot   be   considered   compulsory.   In   fact,   the  
c

onfiguration   of   the   road,   the   amount   of   traffic  
a

nd   safety   remain   determining   factors   when  
c

hoosing   the   best   gear.   Therefore,   the   driver  
r

emains   responsible   for   deciding   whether   or   not  
t

o   follow   the   advice   given   by   the   system.
This
  function   cannot   be   deactivated. -

System
  which   reduces   fuel   consumption   by   recommending   the   most   appropriate   gear.
With   an   electronic   or   automatic   gearbox,   the

  Depending   on   engine. On

Tyre under-inflation detection
System which automatically checks the p
ressures   of   the   tyres   while   driving.
The
  system   continuously   monitors   the  
p

ressures of the four tyres, as soon as the
vehicle
  is   moving.
a

pressure sensor is located in the valve of
each
  tyre   (except   the   spare   wheel).
The
  system   triggers   an   alert   if   a   drop   in  
p

ressure   is   detected   in   one   or   more   tyres.
The
  tyre   under-inflation   detection   system   is   an  
a

id   to   driving   which   does   not   replace   the   need  
f

or   vigilance   on   the   part   of   the   driver.This
  system   does   not   avoid   the   need  
t

o   check   the   tyre   pressures   regularly  
(

including   the   spare   wheel)   and   before  
a

  long   journey.
Driving   with   under-inflated   tyres  
a

dversely   affects   road   holding,  
e

xtends   braking   distances   and   causes  
p

remature   tyre   wear,   particularly   under  a
rduous   conditions   (vehicle   loaded,  h
igh   speed,   long   journey).The tyre pressures for your vehicle can
be
  found   on   the   tyre   pressure   label   (see  
t

he   "Identification   markings"   section).
The   tyre   pressures   must   be   checked  
w

hen   the   tyres   cold   (vehicle   stopped  
f

or   1   hour   or   after   driving   for   less   then  
6

  miles   (10   km)   at   moderate   speed).  
O

ther wise,   add   0.3   bar   to   the   values  i
ndicated   on   the   label.
Driving   with   under-inflated   tyres  
i

ncreases   fuel   consumption.

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

 e

quipment,   the   display   of   a   message.

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   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  
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.

DetectionOperating fault
System which detects the involuntary crossing o
f   longitudinal   traffic   lane   markings   on   the  
g

round   (solid   or   broken   line).
Sensors,
  fitted   below   the   front   bumper,   trigger  
a

  warning   if   the   vehicle   drifts   over   a   lane  
m

arking   (speed   higher   than   50   mph   (80   km/h)).
This
  system   is   particularly   useful   on   motor ways  
a

  the   event   of   a   malfunction,   the  
s

ervice   warning   lamp   comes   on,

It
  is   necessary   to   observe   driving  
r

egulations   and   take   a   break   every  
two
  hours. The
  detection   may   be   impeded:
- i f   the   sensors   are   dirty   (mud,   snow...),

i

f there is little contrast between the
markings
  on   the   ground   and   the   road

You
  are   warned   by   the   vibration   of   the   driver's  
s

eat   cushion:
-
 
o
n   the   right-hand   side,   if   the   marking   on  
t

-
 
o
n   the   left-hand   side,   if   the   marking   on   the

round   has   been   crossed   on   the   left.
No
