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   on.
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.

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.
The
  system   is   not   triggered   or   is   interrupted   if

Safety

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   the
 sen

sor.
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 o
n
 
the
 
windscreen
 
in
 
front
 
of
 
the
 
sensor.
Sensor fault
The operation of the laser sensor may suffer i
nter 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.

Advice
In order to be effective, a seat belt must:
-  b e   tightened   as   close   to   the   body   as  
p

ossible,
-
 
b
e   pulled   in   front   of   you   with   a   smooth  
m

ovement,   checking   that   it   does   not  
t

wist,
-
 
b
e   used   to   restrain   only   one   person,
-
 
n
ot   bear   any   trace   of   cuts   or   fraying,
-
 
n
ot   be   converted   or   modified   to   avoid  
a

ffecting
 it
s
 p
erformance.
In
 
a
ccordance  
w
ith  
c
urrent  
s
afety  
r
egulations,  
f

or   all   repairs   on   your   vehicle's   seat   belts,   go  
t

o   a   qualified   workshop   with   the   skills   and  
e

quipment   needed,   which   a   CITROËN   dealer  
i

s   able   to   provide.
Have
  your   seat   belts   checked   regularly   by  
a

  CITROËN   dealer   or   a   qualified   workshop,  
p

articularly   if   the   straps   show   signs   of  
d

amage.
Clean the seat belt straps with soapy water or
a
  textile   cleaning   product,   sold   by   CITROËN  
d

ealers.
After
  folding   or   moving   a   seat   or   rear   bench  
s

eat,   ensure   that   the   seat   belt   is   positioned  
a

nd   reeled   in   correctly.Recommendations for
children
Use a suitable child seat if the passenger is less   than   12   years   old   or   shorter   than   one  
a

nd   a   half   metres.
Never
  use   the   same   seat   belt   to   secure  
m

ore   than   one   person.
Never
  allow   a   child   to   travel   on   your   lap.
For
  more   information   on   child   seats,   refer   to  
t

he   corresponding   section.
In the event of an impact
depending on the nature and
seriousness of the impact , the
pretensioning
  device   may   be   deployed  
b

efore   and   independently   of   the   airbags.  
D

eployment   of   the   pretensioners   is  
a

ccompanied   by   a   slight   discharge   of  
h

armless   smoke   and   a   noise,   due   to   the  
a

ctivation   of   the   pyrotechnic   cartridge  
i

ncorporated   in   the   system.
In
  all   cases,   the   airbag   warning   lamp  
c

omes   on.
Following
  an   impact,   have   the   seat   belts  
s

ystem  
c
hecked,  
a
nd  
i
f  
n
ecessary  
r
eplaced,  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
The
 
driver
 
must
 
ensure
 
that
 
passengers
 
use
 
t

In the event of a fault with the SCR emissions control system
If it is a temporary fault, the alert disappears   during   the   next   journey,  
a

fter   self-diagnosis   of   the   SCR   system.
A
  system   that   prevents   engine   starting   is   activated   automatically   from   650   miles   (1   100   km)   after   confirmation   of   a   fault   with   the   SCR   emissions  
c

ontrol   system.   Have   the   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop   as   soon   as   possible.
In the event of the detection of a fault
du
ring an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)
The
 
UREA,   SERVICE   and   diagnostic   warning  
l

amps
  comes   on,   accompanied   by   an   audible  
s

ignal
  and   the   display   of   the   message  
"

 f
ault".
The
 
alert   is   triggered   when   driving   when   the  
f

ault
 
is   detected   for   the   first   time,   then   when  
s

witching   on   the   ignition   for   subsequent  
j

ourneys,   while   the   fault   persists. If   a   fault   with   the   SCR   system   is   confirmed   (after
 3

0   miles   (50   km)   covered   with   the   permanent
 d

isplay   of   the   message   signalling   a   fault),   the
 S

 r

emaining   range   express   in   miles   or   kilometres.
While   driving,   the   message   is   displayed   every
 3

0   seconds   while   the   fault   with   the   SCR   system
 p
ersists.
The   alert   is   repeated   when   switching   on   the ig
