Emergency o r 
a

ssistance call
This system allows you to make an emergency o
r   assistance   call   to   the   emergency   services  
o

r   to   the   dedicated   service   (operated   by  
C

ITROËN   Assistance).
For
  more   information   on   the   use   of   this  
f

Safety

Under-inflation detection
System which automatically checks the pressures of the tyres while driving.
T he   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  
i

mpairs   road   holding,   extends   braking  
d

istances   and   causes   premature  
t

yre   wear,   particularly   under   arduous  
c

ondition   (high   loading,   high   speed,  
lon

g
 jo
urney).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.
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.

151
The alert is maintained until the system is r einitialised.
The
 
loss
 
of
 
pressure
 
detected
 
does
 
not
 a
lways
 
cause
 
visible
 
bulging
 
of
 
the

c

heck. Before
  reinitialising   the   system,   ensure  
t

hat the pressures of the four tyres are
correct for the use of the vehicle, as
given
  on   the   tyre   pressure   label.
The
  under-inflation   detection   system  
d

oes   not   give   a   warning   if   a   pressure   is  
i

ncorrect   at   the   time   of   reinitialisation.

Safety

Braking assistance systems
Group of supplementary systems which help you   to   obtain   optimum   braking   in   complete  
s

afety   in   emergency   situations:
-
 
a
nti-lock   braking   system   (ABS),
-
 
e
lectronic   brake   force   distribution   (EBFD),
-
 
e
mergency   braking   assistance   (EBA).Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and manoeuvrability   of   your   vehicle   when   braking,  
i

n   particular   on   poor   or   slippery   sur faces.
Activation
The anti-lock braking system comes into operation   automatically   when   there   is   a   risk   of  
w

heel   lock.
Normal
  operation   of   the   ABS   may   make   itself  
f

elt   by   slight   vibration   of   the   brake   pedal.
When
  braking   in   an   emergency,   press  
v

ery   firmly   without   releasing   the  
p

ressure.
Operating fault
If this warning lamp comes on, together   with   the   STOP  and   ABS
warning
  lamps,   accompanied   by   an  
a

udible
 
signal   and   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   electronic   brake  
f

orce
 
distribution   which   could   result   in   loss   of  
c

ontrol
 
of
  the   vehicle   when   braking.
You must stop as soon as it is safe to do so.
When
  replacing   wheels   (tyres   and  
r

ims),   ensure   that   they   conform   to   the  
ma

nufacturer's
 r
ecommendations.
If
  this   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal  
a

nd   a   message   in   the   screen,   it  
i

ndicates
 
a   malfunction   of   the   anti-lock   braking  
s

ystem
 
which   could   result   in   loss   of   control   of  
t

he
 
vehicle   when   braking.
In
 
either
 
case,   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.

155
Emergency braking assistance
System which, in an emergency, enables you to   obtain   the   optimum   braking   pressure   more  
q

uickly,   thus   reducing   the   stopping   distance.
Activation
It is triggered by the speed at which the brake pedal   is   pressed.
The
  effect   of   this   is   a   reduction   in   the  
r

esistance   of   the   pedal   and   an   increase   in  
b

raking
 e
fficiency.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
The anti-slip regulation (also known as traction control)   optimises   traction   to   prevent   skidding  
o

f   the   wheels,   by   acting   on   the   brakes   of   the  
d

riving   wheels   and   on   the   engine.
The electronic stability control acts on the
brake
  of   one   or   more   wheels   and   on   the   engine  
t

o   keep   the   vehicle   on   the   trajectory   required  
b

y   the   driver,   within   the   limits   of   the   laws   of  
p

hysics.Activation
These systems are activated automatically each   time   the   vehicle   is   started.
They
  come   into   operation   in   the   event   of   a   grip

This
  is   indicated   by   flashing   of   this  
w

arning   lamp   in   the   instrument   panel.
Safety

deactivation

Active City Brake
Active City Brake is a driving assistance system   that   aims   to   avoid   a   frontal   collision  
o

r   reduce   the   speed   of   an   impact   if   the   driver  
d

oes   not   react   sufficiently   (inadequate   brake  
a

pplication). This
  system   is   designed   to   improve  
d

riving   safety.
It
  remains   the   driver's   responsibility   to  
c

ontinuously   monitor   the   state   of   the  
t

raffic   and   to   assess   the   distances   and  
r

elative   speeds   of   other   vehicles.
Active
  City   Brake   can   in   no  
c

ircumstances   replace   the   need   for  
v

igilance   on   the   part   of   the   driver.
Never
  look   at   the   laser   sensor   through  
an o

ptical
 in
strument
 (
magnifying
 g
lass,
 m

icroscope...)   at   a   distance   of   less   than  
1

0   centimetres:   risk   of   eye   injury.Automatic
  braking   occurs   later   than   if  
d

one   by   the   driver,   so   as   to   intervene  
o

nly   when   there   is   a   high   risk   of  
c

ollision.Principle
Using a laser sensor located at the top of the windscreen,   this   system   detects   a   vehicle  
r

unning   in   the   same   direction   or   stationary  
a

head   of   your   vehicle.
When
  necessary,   the   vehicle's   braking   system  
i

s   operated   automatically   to   avoid   a   collision  
w

ith   the   vehicle   ahead.
Conditions for activation
Active City Brake only operates if the following conditions   are   met:
●
 
i
gnition   on,
●
 
t
he   vehicle   is   in   a   for ward   gear,
●
 
s
peed   is   between   about   3   and   18   mph  
(5
  and   30   km/h),
●
 
t
he   braking   assistance   systems   (ABS,  
E

BFD,   emergency   braking   assistance)   are  
n

ot faulty,
●
 
t
he   trajectory   control   systems   (ASR,   DSC)  
a

re   not   deactivated   or   faulty,
●
 
t
he   vehicle   is   not   in   a   tight   corner,
●
 
t
he   system   has   not   been   triggered   during  
t

he   previous   10   seconds.
Safety

Operation
When your vehicle is too close to or
approaches  the   vehicle   ahead   too   quickly   the  
s

ystem   automatically   applies   the   brakes   to  
a

void   a   collision.
The
  collision   can   be   avoided   automatically   if   the
 d

ifference   in   speed   between   your   vehicle   and   the
 v

ehicle   ahead   does   not   exceed   9   mph   (15   km/h).
Above
  this   threshold,   the   system   will   do   what
 i

s   possible   to   avoid   or   reduce   the   accident   by
 l

owering   the   speed   of   impact.
The
  automatic   braking   may   bring   the   vehicle   to  
a

  complete   stop   if   the   situation   requires   it.
In
  this   case,   the   vehicle   is   held   stationary  
t

emporarily   (for   about   1.5   seconds)   to   allow  
t

he   driver   to   take   back   control   by   pressing   the  
b

rake
 ped
al.
You
  are   then   alerted   by   the   display   of   a  
m

essage.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users.
After
  an   impact,   the   system   is  
a

utomatically   put   out   of   service:   it   no  
lon

ger
 ope
rates.
You
  must   go   to   a   CITROËN   dealer   or   a  
q

ualified   workshop   to   have   the   system  
m

ade   operational   again.
During
  automatic   braking,   the   driver  
c

an   always   obtain   a   higher   rate   of  
d

eceleration   than   that   controlled   by   the  
s

ystem,   by   pressing   firmly   on   the   brake  
ped

al.
The
  triggering   of   the   system   may   cause  
t

he   engine   to   stall,   unless   the   driver  
d

epresses   the   clutch   pedal   quickly  
e

nough   during   automatic   braking.
deactivation
The system is deactivated in the vehicle configuration   menu,   accessible   with   the   ignition  
o

n.
Its
  state   is   memorised   when   the   ignition   is  
s

witched off. When
  the   system   is   deactivated,   a  
m

essage   is   displayed   every   time   the  
i

gnition   is   switched   on,   to   warn   you.
