Warning triangle
This safety device should be used in addition to the   hazard   warning   lamps.
Its
  presence   in   the   vehicle   is   mandatory.
A

211
Under-inflation detection
The system monitors the pressures in the four t
yres,   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  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  
p

articularly   under   arduous   condition  
(

high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
See
  the   "Identification   markings"  
s

ection.
Tyre
  pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   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.

Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and manoeuvrability   of   your   vehicle   when   braking  
a

nd   contributes   towards   improved   control   in  
c

orners,   in   particular   on   poor   or   slippery   road  
su

rfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  electronic   brake   force   distribution   system  
m

anages   the   braking   pressure   wheel   by   wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach   the   optimum   braking   pressure   more  
q

uickly   and   therefore   reduce   the   stopping  
di

stance.
It
  is   triggered   according   to   the   speed   at   which  
t

he   brake   pedal   is   pressed.   This   is   felt   by   a  
r

eduction   in   the   resistance   of   the   pedal   and   an  
i

ncrease   in   the   effectiveness   of   the   braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control)   optimises   traction   in   order   to   limit  
w

heel   slip   by   acting   on   the   brakes   of   the   driving  
w

heels   and   on   the   engine.   It   also   improves  
t

he   directional   stability   of   the   vehicle   on  
a

cceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed   by   the   vehicle   and   that   required   by  
t

he   driver,   the   DSC   monitors   each   wheel   and  
a

utomatically   acts   on   the   brake   of   one   or   more  
w

heels   and   on   the   engine   to   return   the   vehicle  
t

o   the   required   path,   within   the   limits   of   the   laws  
o

f   physics.

Intelligent traction control
system ("Snow motion")
When this warning lamp comes on, coupled   with   the   STOP w arning lam p, a

ccompanied   by   an   audible   signal   and   a
 m

essage,   it   indicates   that   there   is   a   fault
 w

ith   the   electronic   brake   force   distribution
 (

EBFD),   which   could   cause   loss   of   control
 o

f   the   vehicle   when   braking.
Operation
When this warning lamp comes on, accompanied   by   an   audible   signal  
a

nd   a   message,   it   indicates   that   there  
i

s   a   fault   with   the   ABS,   which   could  
c

ause loss of control of the vehicle
when
 b

raking. Depending
  on   version,   your   vehicle   has   a  
s

ystem   to   help   driving   on   snow:   intelligent
traction control .
This   system   detects   situations   of   difficult  s
ur face   adhesion   that   could   make   it   difficult   to  
m

ove   off   or   make   progress   on   deep   fresh   snow  
o

r   compacted   snow.
In these situations, the intelligent traction
control
 

limits   the   amount   of   wheel   slip   to  
p

rovide   the   best   traction   and   trajectory   control  
f

or   your   vehicle.
The
  use   of   snow   tyres   is   strongly  
r

ecommended   on   sur faces   offering   low   levels  
o

f   adhesion.

our   vehicle.
Normal
  operation   of   the   ABS   may   make  
i

tself   felt   by   slight   vibrations   of   the   brake

al.
In emergency braking, press
very firmly without releasing the
pressure.
You must stop as soon as it is safe to do so.

Dynamic stability control (DSC)
and anti-slip regulation (ASR)Activation
These systems are activated automatically each   time   the   vehicle   is   started.
As
  soon   as   they   detect   a   problem   of   grip   or  
t

rajectory,   these   systems   act   on   the   operation   if  
t

he   engine   and   brakes.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate  
t

he   DSC   and   ASR,   so   that   the   wheels   can   turn  
f

reely   and   regain   grip.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this
 
w

arning
 
lamp
 
in
 
the
 
instrument
 
panel. Reactivate
  the   systems   as   soon   as   the   level   of  
g

rip   permits. F
 
P

This
  indicator   lamp   and   the   indicator  
l

amp   in   the   button   come   on.
The
  DSC   and   ASR   systems   no   longer   act  
o

n   the   operation   of   the   engine   and   on   the  
b

rakes   in   the   event   of   a   involuntary   change   of  
t

rajectory.
DSC/ASR
The DSC and ASR systems offer increased s afety   in   normal   driving,   but   they   should   not  
e

ncourage   the   driver   to   take   extra   risks   or   drive  
a

t   high   speed.
It
  is   in   conditions   of   reduced   grip   (rain,   snow,  
i

ce)   that   the   risk   of   loss   of   grip   increases.  
I

t   is   therefore   important   for   your   safety   to  
k

eep   the   DSC   and   ASR   systems   activated  
i

n   all   conditions,   and   particularly   in   difficult  
c

onditions. The
  correct   operation   of   these   systems  
d

epends   on   observation   of   the   manufacturer's  
r

ecommendations   regarding   as   much   the  
w

heels   (tyres   and   rims),   braking   and   electronic  
c

omponents   as   the   assembly   and   repair  
p

rocedures   used   by   CITROËN   dealers.
To   benefit   in   full   from   the   effectiveness   of   the  
D

SC   and   ASR   systems   in   wintry   conditions,  
t

he   vehicle   must   be   fitted   with   four   snow  
t

yres,   allowing   the   the   vehicle   to   retain   neutral  
b

ehaviour   on   the   road.

Seat belts
Front seat belts
The front seat belts are fitted with a pretensioning   and   force   limiting   system.
This
  system   improves   safety   in   the   front  
s

eats   in   the   event   of   a   front   or   side   impact.  
D

epending   on   the   severity   of   the   impact,   the  
p

retensioning   system   instantly   tightens   the   seat  
b

elts   against   the   body   of   the   occupants.
The
  pretensioning   seat   belts   are   active   when  
t

he   ignition   is   on.
The
  force   limiter   reduces   the   pressure   of   the  
s

eat belt on the chest of the occupant, so
improving
  their   protection.
Seat belt reels with reversible
pretension
This system provides automatic adjustment of the   tension   of   the   driver's   and   passenger's   seat  
b

elts   after   fastening,   once   the   vehicle's   speed  
i

s   above   6   mph   (10   km/h).
In
  addition,   as   soon   as   the   system   detects  
a

  potentially   dangerous   driving   situation,  
t

his   system   reacts   by   drawing   in   slack   in  
t

he   belt,   (for   example,   under   heavy   or   sharp  
b

raking   or   sudden   avoiding   manoeuvres).   By  
a
