The change from one level of alert
to the next takes place if the driving
conditions do not change (speed
unchanged, no change of lane...)
Severe weather conditions (very heavy
rain, accumulation of snow in front
of the radar) may interfere with the
operation of the system, resulting in
the display of the message "
System
inactive: Reduced visibility
". The
system remains unavailable until the
message disappears.
If the speed of your vehicle is too high
when approaching another vehicle, the
first level of alert may not be displayed:
the level 2 alert may be displayed
directly.
On the other hand, the level 1 alert
is never displayed with the triggering
threshold 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)
indicating that the vehicle in front is
very close. The message "
Vehicle
close
" is displayed.
Level 2
: visual (red) and audible
alerts indicating that a collision is
imminent. 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
dynamics, the speed of your vehicle and
the speed of the vehicle in front, the driving
conditions, the situation with your vehicle
(cornering, pedals pressed, etc.) to trigger the
alert at the right moment.
Level 3
: an increase in
the tension of the driver's
seat belt, to hold the driver
against the backrest of their
seat.
The 3
rd
level of alert is not triggered or
is interrupted in the event of an impact
between the two vehicles.
the increase in the tension of the
driver's seat belt is intended only as an
alert: it does not in any circumstances
assure the function of driver safety.
The triggering of this alert does not act
on the safety functions provided by the
seat belts.
