Under-inflation detection
The system monitors the pressures in the four
tyres,
  once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects a drop in the inflation pressure of one
or
  more   tyres. The under-inflation detection system
does
  not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This system does not avoid the need to
check
  the   tyre   pressures   (including   the  
s

pare wheel) every month as well as
before
  a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd causes premature tyre wear,
particularly under arduous conditions
(high
  loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure
  label.
For more information on the
Identification markings , refer to the
corresponding
 s

ection.
Tyre
  pressures   should   be   checked  
w

hen the tyres are "cold" (vehicle
stopped
  for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Halogen headlamps
For   motoring   in   countries   that   drive

Operation of the rear foglamps is inhibited   with   the   tailgate   open.
Opening
  the   tailgate   when   these   lamps  
a

re on causes them and their indicator
lamp
  in   the   instrument   panel   to   go   off.
They
  do   not   come   back   on  
a

utomatically   when   the   tailgate   is  
c

losed:   they   must   be   switched   on   again  
u

sing   the   control   stalk. In
  good   or   rainy   weather,   by   both   day  a
nd   night,   the   front   foglamps   and   the  
r

ear   foglamps   are   prohibited.   In   these  
s

ituations, the power of their beams
may
  dazzle   other   drivers.   They   should  
o

nly   be   used   in   fog   or   falling   snow.
In these weather conditions, you should
switch
  on   the   foglamps   and   dipped  
b

eam headlamps manually, as the
sunshine sensor may detect sufficient
light.
Do
  not   forget   to   switch   off   the   front   and  
r

ear   foglamps   when   they   are   no   longer  
n

ecessary.Switching off the lighting
when switching off the ignition
When the ignition is switched off, all of the lamps   switch   off   immediately,   except   for   the d

ipped   beam   headlamps   if   automatic   guide-
me-home
  lighting   is   activated.
Switching on the lighting when
switching on the ignition
To reactivate the lighting control stalk, turn the   ring   A to position "0" 
-   lighting   off,   then t

o   the   position   of   your   choice.
When the driver's door is opened, a temporary   audible   signal   warns   you   that  
t

he   vehicle's   lighting   is   on.
They switch off automatically after a period
which  depends   on   the   state   of   charge   of   the b

attery   (entry   to   energy   economy   mode).

Airbags
System designed to contribute towards improving   the   safety   of   the   occupants   (with  
t

he   exception   of   the   rear   centre   passenger)  
i

n   the   event   of   violent   collisions.   The   airbags  
s

upplement   the   action   of   the   force-limiting  
s

eat   belts   (with   the   exception   of   the   rear   centre  
p

assenger).
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained
  in   the   impact   detection   zones:
-
 
i
n   the   case   of   a   serious   impact,   the   airbags  
a

re deployed instantly and contribute
towards better protection of the occupants
of
  the   vehicle   (with   the   exception   of   the  
r

ear   centre   passenger);   immediately   after  
t

he   impact,   the   airbags   deflate   rapidly   so  
t

hat   they   do   not   hinder   visibility   or   the   exit  
o

f the occupants,
-

i
n the case of a minor or rear impact or in
certain
  roll-over   conditions,   the   airbags  
m

ay   not   be   deployed;   the   seat   belt  
a

lone   contributes   towards   ensuring   your  
p

rotection   in   these   situations.
The airbags do not operate when the
ignition is switched off.
This
  equipment   will   only   deploy   once.  
I

f   a   second   impact   occurs   (during   the  
s

ame or a subsequent accident), the
airbag
  will   not   be   deployed   again. Deployment of one or more of the
airbags
  is   accompanied   by   a   slight  
e

mission   of   smoke   and   a   noise,   due  
t

o the activation of the pyrotechnic
cartridge
  incorporated   in   the   system.
This
  smoke   is   not   harmful,   but   sensitive  
i

ndividuals   may   experience   slight  
ir

ritation.
The noise of detonation related to the
deployment
  of   one   or   more   airbags   may  
r

esult   in   a   slight   loss   of   hearing   for   a  
s

hort   time.
