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 electronic stability
programme (ESP)
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   programme   acts   on   the  
b

rake   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

Safety

deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate   the  
A

SR   and   ESP   systems,   so   that   the   wheels   can  
m

ove   freely   and   regain   grip.

Active City Brake
Active City Brakeis a driving assistance system that   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does  
n

ot   take   sufficient   action   (inadequate   brake  
a

pplication).
This system is designed to improve driving safety.
I t   remains   the   driver's   responsibility   to c

ontinuously   monitor   the   state   of   the   traffic   and
 t

o   assess   the   distances   and   relative   speeds   of
 o

ther
 v
ehicle.
Active
  City   Brakecan   in   no   circumstances   replace
 t

he   need   for   vigilance   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 Brakeonly 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.

163
Operating limits
The system only detects vehicles that are stationary   or   moving   in   the   same   direction   as  
y

our   vehicle.
It
  does   not   detect   small   vehicles  
(

bicycles,   motorcycles),   pedestrians   or  
a

nimals,   nor   non-reflective   stationary  
ob

jects. In
  difficult   weather   conditions   (very  
h

eavy   rain,   snow,   fog,   hail...),   braking  
d

istances   increase,   which   can   reduce  
t

he   ability   of   the   system   to   avoid   a  
c

ollision.
The
  driver   must   therefore   remain  
par

ticularly
 v
igilant.
Never
  leave   accumulations   of   snow   or  
a

ny   object   projecting   above   the   bonnet  
o

r   in   front   of   the   roof:   this   might   fall   into  
t

he   field   of   vision   of   the   sensor   and  
g

enerate   a   detection.
The
  system   is   not   triggered   or   is   interrupted   if  t
he d river:
-
 
a
ccelerates   strongly
-
 
o
r   turns   the   steering   wheel   suddenly  
(

avoiding
 m
anoeuvre).
Safety

deactivation
The system is deactivated in the vehicle configuration   menu,   accessible   with   the   ignition   on.
Its state is memorised when the ignition is switched   off.
When

Operating faults
In the event of an impact to the windscreen   at   the   sensor,   deactivate  
t

he   system   and   contact   a   CITROËN  
d

ealer   or   a   qualified   workshop to   have  
y

our   windscreen   replaced.
Never
  try   to   remove,   adjust   or   test  
t

he sensor.
Only
  a   CITROËN   dealer   or   a   qualified
 w

orkshop   is   able   to   work   on   the   system.
When
  towing   a   trailer   or   when   the  
v

ehicle   is   being   towed,   the   system   must  
b

e   deactivated.
Do not stick or other wise fix any object on the   windscreen   in   front   of   the   sensor.
Sensor fault
The operation of the laser sensor may suffer inter ference   from   accumulations   of   dirt   or  
m

isting   of   the   windscreen.   In   this   case   you   are  
w

arned   by   the   display   of   a   message.
Use
  the   windscreen   demisting   and   regularly  
c

lean   the   area   of   the   windscreen   in   front   of   the  
sen

sor.
System fault
In the event of a malfunction of the system, you are   warned   by   an   audible   signal   and   the   display  
o

f   the   message   "Automatic braking system
fault" .
Have
  the   system   checked   by   a   CITROËN  
d

ealer   or   a   qualified   workshop.
Safety

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.
Fastening
F Pull  the   strap,   then   insert   the   tongue   in   the  buc
kle.

orrectly   by   pulling   the   strap.
Unfastening
F Press  the   red   button   on   the   buckle.
F  G uide   the   seat   belt   as   it   is   reeled   in.
Seat belt not fastened /
unfastened warning lamp
When the ignition is switched on, this warning   lamp   comes   on   in   the   instrument p

anel,   if   the   driver   and/or   the   front
 p

assenger   has   not   fastened   their   seat   belt.
From approximately 12 mph (20 km/h) this   warning   lamp   flashes   for   two   minutes  
a

ccompanied   by   an   audible   signal   of   increasing  
v

olume.   Once   these   two   minutes   have   elapsed,  
t

his   warning   lamp   remains   on   until   the   driver  
a

nd/or   the   front   passenger   fastens   their  
seat
  belt.
