The TRC and DSC systems offer increased   safety   in   normal   driving,   but  
s

hould   not   encourage   the   driver   to   take  
e

xtra   risks   or   drive   at   high   speed.
The correct operation of these
systems
  depends   on   observation   of  
t

he

egarding   the   wheels   (tyres   and   rims),  
t

he   braking   components,   the   electronic  
c

omponents   and   the   assembly   and  
r

epair   procedures   used   by   CITROËN  
d

ealers.
After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a

ualified

orkshop.
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  
D

SC   and   TRC   systems,   so   that   the   wheels   can  
s

pin   freely   and   regain   grip.
Operating fault
However, it is recommended that these systems   be   reactivated   as   soon   as   possible.

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

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

  increases   the  
b

raking   started   by   the   driver,   only   if   a   risk

  when  
y

our   vehicle   is   too   close   to   or   closing  
t

t

b

rakes   to   reduce   the   speed   of   impact.   A

his   warning   lamp,   accompanied   by  
a

  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
