Active City Brake
Active City B rake  i s  a  d riving  a ssistance  s ystem  t
hat   aims   to   avoid   a   frontal   collision   or   reduce  
t

he   speed   of   an   impact   if   the   driver   does   not  
r

eact   or   reacts   too   late   (brake   application   too  
l

ate). 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  
a

n   optical   instrument   (magnifying   glass,  
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 and a camera located at the   top   of   the   windscreen,   this   system   detects  
a

  vehicle   running   in   the   same   direction   or  
s

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

s   operated   automatically   to   reduce   the   speed  
o

f   impact   or   to   help   avoid   a   collision   with   the  
v

ehicle
 a
head.
Conditions for activation
Active City Brake only operates if the following

-
 
t

Operation
Three levels of operation are possible:
●  P re-collision alert :
  if   a   risk   of   collision w

ith   a   vehicle   is   detected,   a   warning   lamp
 c

omes   on   in   the   instrument   panel   together
 w

ith   an   audible   signal   to   encourage   the
 d

river   to   make   an   avoiding   manoeuvre.   The
 t

hresholds   for   triggering   the   alert   can   be   set.
●
 
Br
aking assistance :
  increases   the  
b

raking   started   by   the   driver,   only   if   a   risk  
o

f   collision   is   detected.
●
 
A
utomatic pre-collision braking:
  when  
y

our   vehicle   is   too   close   to   or   closing  
t

oo   quickly   on   the   vehicle   ahead   of   you,  
t

he   system   automatically   operates   the  
b

rakes   to   reduce   the   speed   of   impact.   A  
c

ollision   can   be   avoided   automatically   if   the

  are   then   alerted   by   the   display   of  
t

his   warning   lamp,   accompanied   by  
a

n   audible   signal. The
  automatic   braking   may   bring   the   vehicle   to  a
  complete   stop   if   the   situation   requires   it.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users. The
  triggering   of   the   system   may   cause  
t

he   engine   to   stall,   unless   the   driver  
d

epresses   the   clutch   pedal   quickly  
e

Setting the alert thresholds
Press this button repeatedly to cycle through   the   thresholds.
The
  default   setting   is   "Normal".
The
 
alert
 
thresholds   determine   how   you   want   to   be   warned   of   the   imminent   risk   of   collision   with   the  
v

ehicle
 
ahead   of   you.
You
 
can
 
choose   one   of   three   thresholds:
A.
 "

Far",
  to   be   given   early   warning   (cautious   driving).
B.
 "

Normal".
C.
 "

Close",   for   a   later   warning   (sporty   driving).
Deactivation / Reactivation
Press this button for more than 3 seconds.
P ress   the   button   again   to   reactivate   the   system.
The

Electrical energy economy mode*
System which manages the duration of use of certain functions to conserve a sufficient level of charge   in   the   battery.
After
  the   engine   has   stopped,   you   can   still   use   functions   such   as   the   audio   system, windscreen  
w

ipers,   dipped   beam   headlamps, courtesy   lamps,   etc.   for   a   maximum   combined   duration   of  
t

wenty minutes.
This
  period   may   be   greatly   reduced   if   the   battery   is   not   fully   charged.
Let
  the   engine   run   for   the   duration  
s

pecified   to   ensure   that   the   battery  
c

harge   is   sufficient.
Do
  not   repeatedly   and   continuously  
r

estart   the   engine   in   order   to   charge   the  
b

attery.
A
  flat   battery   prevents   the   engine   from  
s

tarting.
Refer
  to   the   "Battery"   section.
Switching to economy mode
Once this time has elapsed the active functions are   put   on   standby.
Exiting economy mode
These functions are reactivated automatically next   time   the   vehicle   is   driven.
To restore the use of these functions
immediately,
  start   the   engine   and   let   it   run   for   at

Practical information

Checking levels
Take care when working under the bonnet,   as   certain   areas   of   the   engine  
m

ay   be   extremely   hot   (risk   of   burns)   and  
t

he   cooling   fan   could   start   at   any   time  
(

even   with   the   ignition   off).
Engine oil level
The check of the oil level is carried out   with   the   dipstick,   located   under  
t

he   bonnet.   For   the   position   of   the  
d

ipstick,   refer   to   the   under-bonnet  
v

iew   on   a   previous   page.
Checking with dipstick
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
To
  ensure   the   accuracy   of   the   reading,  
y

our   vehicle   must   be   on   a   level  
s

ur face,   with   the   engine   off   for   at   least  
3

0 minutes.
It
  is   normal   to   top   up   the   oil   level   between  
t

wo   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   km). If
  you   find   that   the   oil   level   is   above   the   A   mark  
o

r below the B   mark,   do not star t the engine.
-
 
I
f   the   level   is   above   the   MAX
 
mark   (risk  
o

f   engine   damage),   contact   a   CITROËN  
d

ealer   or   a   qualified   workshop.
-
 
I
f   the   level   is   below   the   MIN
 
mark,   you  
m

ust   top-up   the   engine   oil.
Refer
  to   the   under-bonnet   view   for   the   location  
o

f   the   dipstick   on   your   vehicle.
F
 
T
ake   the   dipstick   by   its   coloured   grip   and

F
 
R
efit   the   dipstick   and   push   it   fully   down,  
t

hen   pull   it   out   again   for   a   visual   check   of  
t

he   oil   level:   the   level   must   be   between   the  
t

wo   marks   A   and   B.
