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

e,
-
 
v
ehicles   entering   a   corner,
-
 
v
ehicles   suddenly   pulling   out.The
  cruise   control   does   not   take   account   of:
-
 
p
edestrians,   cyclists,   animals,
-
 
s
tationary   vehicles   (traffic   jam,   red   light,  
b

reakdown...),
-

ehicles   crossing   a   junction,
-
 
v
ehicles   driving   in   the   opposite   direction.

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 "

The
  collision   risk   alert   system   can   never  
r

eplace   the   need   for   vigilance   on   the  
p

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

  alert   thresholds   determine   how   you   want   to  
b

e   alerted   to   the   presence   of   a   vehicle   running
