Limits of operation
The system cannot exceed the limits of the laws   of   physics.
It
  is   recommended   that   the   system   be  
d

eactivated   when   the   "space-saver"   spare  
w

heel   is   in   use.
The
  system   should   not   be   activated   when  
t

owing   a   trailer.
In
  certain   critical   situations,   the   system   will  
e

ncourage   the   driver   to   immediately   take   back  
c

ontrol:
-
 
i
f   the   vehicle   in   front   slows   down   too   much  
o

r   too   suddenly,   and   the   driver   does   not  
b

rake,
-
 
i
f   a   vehicle   comes   between   your   vehicle  
a

nd   the   vehicle   in   front. As
  the   radar's   field   of   detection   is   quite   narrow,  
i

t   is   possible   that   the   system   may   not   detect:
-
 
v
ehicles   of   reduced   width   (motorcycles,  
s

cooters...),
-
 
v
ehicles   not   running   in   the   middle   of   the  
lan

-
 
v

Operating fault
As a safety measure, do not use the system if the   brake   lamps   are   faulty.
Do
  not   use   the   system   if   the   front   bumper   is

Collision risk alert
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.
T he   collision   risk   alert   system   can   be   activated  
o

r   deactivated   in   the   touch   screen   tablet.
In the Driving
 

menu,   select   the   "Settings " tab,
then " Driving aid "
  and   "Collision risk alert ".
This
  system   has   been   designed   to  
i

mprove   driving   safety.
It
  is   the   responsibility   of   the   driver   to  
k

eep   a   constant   check   on   the   state   of  
t

he   traffic,   to   assess   the   relative   speed  
a

nd   distance   of   other   vehicles.
The
  collision   risk   alert   system   can   never  
r

eplace   the   need   for   vigilance   on   the  
p

art   of   the   driver.
This
  system   operates   from   20   mph  
(

30 km/h),   only   when   other   vehicles   are  
r

unning   in   the   same   direction   as   your  
v

ehicle;   the   system   does   not   detect  
s

tationary   objects.   A   radar   is   fitted   at  
t

he   front   of   the   vehicle. The
  alert   thresholds   determine   how   you   want   to  
b

e   alerted   to   the   presence   of   a   vehicle   running  
i

n   front   of   you.
You
  can   choose   from   three   thresholds:
-
 
1
:   "Distant ".
-
 
2
:   "Normal ".
-
 
3
:   "Close ".
Setting the thresholds for
the alert
This function can be deactivated p
ermanently   by   a   CITROËN   dealer  
or
  a   qualified   workshop.
In the Driving
 

menu,   select   the   "Settings " tab,
then " Driving aid "
  and   select   the   symbol   for  
t

he "Collision risk alert "
  function:
F
 
m
odify   the   alert   threshold   using   the   arrows  
o

r   the   cursor.
Driving

175
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...)

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.

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
