Hill start assist
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a brief
moment when you release the brake pedal:
- 
i
f   you   are   in   first   gear   or   neutral   with   a  
m

anual
 g
earbox,
-

i
f you are in position D or M with an
automatic
  gearbox.
Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a brief moment when you
release the brake pedal.
Operating fault
If a fault occurs with the system, these warning lamps   come   on.   Contact   a   CITROËN   dealer  
o

r   a   qualified   workshop   to   have   the   system  
c

hecked.
System
 
which
 
keeps

vehicle
 
immobilised
 
t

emporarily
 
(approximately
 
2
 
seconds)
 
when
 
s

is
 
only
 
active
 
when:

vehicle
 
is
 
completely
 
stationary,
 
with

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.
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.
For m ore i nformation o n id entification m
arkings,   including   the   tyre   pressure  
l

abel,   refer   to   the   corresponding  
s

ection.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

 i

llumination   of   the   service   warning
 l

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

 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.

Lane departure warning system
Activation
Deactivation
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

nd   main   roads. In
  the   event   of   a   malfunction,   the  
s

ervice   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen.
Contact   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
The   lane   departure   warning   system  
c

annot   in   any   circumstances   replace  
t

he   need   for   vigilance   on   the   part   of   the  
d

river.
It
  is   necessary   to   observe   driving  
r

egulations   and   take   a   break   every  
t

wo hours. The
  detection   may   be   impeded:
- i f   the   sensors   are   dirty   (mud,   snow...),
-
 
i
f   the   markings   on   the   ground   are  
w

orn,
-

i
f there is little contrast between the
markings
  on   the   ground   and   the  
r

oad   sur face.
You
  are   warned   by   the   vibration   of   the   driver's  
s

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

he   ground   has   been   crossed   on   the   right,
-
 
o
n   the   left-hand   side,   if   the   marking   on   the  
g

round   has   been   crossed   on   the   left.
No
  warning   is   transmitted   while   the   direction  
i

ndicator   is   active   and   for   approximately  
2

0 seconds after the direction indicator is
switched
  off.
A
  warning   may   be   transmitted   if   a   direction  
m

arking   (e.g.   arrow)   or   non-standard   marking  
(

e.g.   graffiti)   is   crossed.
