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
damaged. In the event of a fault with the cruise
control, you are alerted by the
illumination
  of   this   warning   lamp

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
rain, accumulation of snow in front
of the radar) may inter fere with the
operation
  of   the   system,   resulting   in  
t

he   display   of   the   message   "SYSTEM  
I

NACTIVE:   Reduced   visibility".   The  
s

ystem remains unavailable until the
message
 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
di r e c t l y.
On the other hand, the level 1 alert
is
  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
levels
  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
time
  between   your   vehicle   and   the   one   in   front.
This level of alert is based on a time before
collision.
  It   takes   account   of   the   vehicle  
d

ynamics, the speed of your vehicle and
the
  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
qualified
 w

orkshop.
The operation of the radar, located in
the front bumper, may be disturbed by
accumulations
  of   grime   (dust,   mud...)  
o

r in certain weather conditions (snow,
ice...).
The
  message   "SYSTEM   INACTIVE:  
V

isibility   reduced"   is   displayed   to   signal  
t

hat the system has been put into
st a n dby.
Clean
  the   front   bumper   regularly.
