CITROEN C 3 2020 Handbook page 93

It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function
automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front or
with a pedestrian present in their traffic lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via theDriving /
Vehicle touch screen menu.
► Select one of the three pre-defined
thresholds:
– "Distant".
– "Normal".
– "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed in
the instrument panel.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message "Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake!" is displayed.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake
This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
