Alerts
According to the collision risk detected by
the system and the alert threshold chosen,
different levels of alert can be given.
Level 1 : visual alert only (orange)
indicating that the vehicle in front is
very close. The message " Vehicle
close " is displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the one in front.
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 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.
The emergency collision alert system
does not replace the vigilance and
responsibility of the driver.
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...)
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 "close"
triggering threshold 3.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) may interfere with the
operation of the system, resulting in
the display of this message " SYSTEM
INACTIVE: Reduced visibility ". The
system will remain unavailable until the
message disappears.
