The change from one level of alert to   the   next   takes   place   if   the   driving  
c

onditions   do   not   change   (speed  
u

nchanged,   no   change   of   lane...)
Severe
  weather   conditions   (very   heavy  
r

ain,   accumulation   of   snow   in   front  
o

f   the   radar)   may   inter fere   with   the  
o

peration   of   the   system,   resulting   in  
t

he   display   of   the   message   "SYSTEM  
I

NACTIVE:   Reduced   visibility".   The  
s

ystem   remains   unavailable   until   the  
m

essage
 d
isappears.
If
  the   speed   of   your   vehicle   is   too   high  
w

hen   approaching   another   vehicle,   the  
f

irst   level   of   alert   may   not   be   displayed:  
t

he   level   2   alert   may   be   displayed  
d

i r e c t l y.
On
  the   other   hand,   the   level   1   alert  
i

s   never   displayed   with   the   triggering  
t

hreshold   3   (close).
Alerts
According to the collision risk detected by the system   and   the   alert   threshold   chosen,   three  
l

evels   of   alert   can   be   triggered.
Level 1 :
  visual   alert   only   (orange)  
i

ndicating   that   the   vehicle   in   front   is  
v

ery   close.   The   message   "Vehicle
close "
  is   displayed.
Level 2 :
  visual   (red)   and   audible  
a

lerts   indicating   that   a   collision   is  
i

mminent.   The   message   "Brake! " is
displayed.
This
  level   of   alert   is   based   on   the   inter-vehicle  
t

ime   between   your   vehicle   and   the   one   in   front.
This
  level   of   alert   is   based   on   a   time   before  
c

ollision.   It   takes   account   of   the   vehicle  
d

ynamics,   the   speed   of   your   vehicle   and  
t

he   speed   of   the   vehicle   in   front,   the   driving  
c

onditions,   the   situation   with   your   vehicle  
(

cornering,   pedals   pressed,   etc.)   to   trigger   the  
a

lert   at   the   right   moment.
Operating fault
In the event of a fault, you are alerted by   the   display   of   the   Service   warning  
l

amp,   accompanied   by   a   message.
Consult
  a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
The
  operation   of   the   radar,   located   in  
t

he
  front   bumper,   may   be   disturbed   by  
a

ccumulations   of   grime   (dust,   mud...)  
o

r
 
in   certain   weather   conditions   (snow,  
i

ce...).
The
  message   "SYSTEM   INACTIVE:  
V

isibility   reduced"   is   displayed   to   signal  
t

hat   the   system   has   been   put   into  
s

t a n dby.
Clean
  the   front   bumper   regularly.

Assisted lane departure warning system
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this systems corrects the trajectory of the vehicle while alerting   the   driver   if   it   detects   a   risk   of   involuntary   crossing   of   a   line.
This
  system   is   particularly   useful   on   motor ways   and   main   roads.
The
  assisted   lane   departure   warning

ystem   cannot,   in   any   circumstances,

f   the   driver.
The
  driver   remains   responsible   for   the
 v

ehicle   in   all   circumstances.   The   system
 h

elps   the   driver   only   when   there   is   a   risk
 o

f   the   vehicle   involuntarily   wandering
 f

rom   the   lane   it   is   being   driven   on.
 I

t   does   not   manage   the   safe   driving
 d

istance,   the   speed   of   the   vehicle   or   the
 b

rakes.
The
  driver   must   hold   the   steering   wheel
 i

n   a   way   that   allows   control   to   be   taken
 b

ack   in   circumstances   where   the   system
 i

s not able to intervene (where there are
no
  lane   markings,   for   example).
It
  is   necessary   to   observe   the   driving
 r

egulations   and   take   a   break   every
 t

wo hours.
Operation
Conditions for operation
The speed of the vehicle must be between 40 a
nd   112   mph   (65   and   180   km/h).
The
  carriageway   must   have   at   least   one   lane  
m

arking   (solid   or   broken)   on   the   ground.
The
  driver   must   hold   the   wheel   with   both  
han

ds.
The
  change   of   trajectory   is   not   accompanied   by  
o

peration   of   the   direction   indicators.
The
  ESC   system   must   be   activated. Once
  the   system   identifies   a   risk   of   the   vehicle  i
nvoluntarily   crossing   one   of   the   lane   markings  
d

etected,   it   makes   the   correction   to   the  
t

rajectory   necessary   to   return   the   vehicle   to   its  
in

itial
 pa
th.
The
  driver   will   then   notice   a   turning   movement  
o

f   the   steering   wheel.
This
  warning   lamp   flashes   during  
t

rajectory
 c
orrection.
If
  the   driver   wishes   to   maintain   the  
t

rajectory   of   the   vehicle,   they   can  
p

revent   the   correction   by   keeping   a   firm  
g

rip   on   the   wheel   (during   an   avoiding  
m

anoeuvre,   for   example).
The
  correction   is   interrupted   if   the  
d

irection   indicators   are   operated.
Driving

177
However, with the "Blind spot monitoring system"   activated,   if   the   driver   starts   changing  
l

ane   and   another   vehicle   is   detected   in   the  
v

ehicle's   blind   spot,   the   system   will   correct  
t

he   trajectory   of   the   vehicle   even   though   the  
d

irection   indicators   are   on.
For
  more   information   on   the   Blind spot
monitoring system ,
  refer   to   the   corresponding  
s

ection. If
  the   system   detects   that   the   driver   is  
n

ot   holding   the   wheel   firmly   enough  
d

uring   an   automatic   correction   of  
t

rajectory,   it   interrupts   the   correction.  
A

n   alert   is   triggered   to   encourage  
t

he   driver   to   take   back   control   of   the  
v

ehicle.
Activation / Deactivation
Activation / deactivation of the system is done i
n the Driving  menu   of   the   touch   screen   tablet.
Select the " Driving assistance " tab then
" Help staying in lane ".
The
  state   of   the   system   stays   in   memory   when  
t

he   ignition   is   switched   off.
While
 
the
 
direction
 
indicators
 
are
 
on
 
and
 
for
 
a

 
few
 
seconds
 
after
 
switching
 
them
 
off,
 
the
 
s

ystem
 
considers
 
that
 
any
 
change
 
of
 
trajectory
