This is a normal behavior indicating that a
condition is not fulfilled and which does not
request the support of a workshop.
In any situations with ignition on where automatic
braking presents a risk, deactivating the system
via the driving aids touch screen application is
recommended, for instance:
– Towing a trailer (particularly a trailer without
its own braking system).
– Carrying long objects on roof bars.
– Driving with snow chains.
– Using an automatic car wash.
– Performing any maintenance (e.g.changing a
wheel, working inside the engine compartment).
– Placing the vehicle on a rolling bench in a
workshop.
– Towing the vehicle.
– Following an impact to the windscreen close to
the detection camera.
The system is automatically deactivated
once the use of a different diameter
"space-saver" type spare wheel is detected, or
if a fault with the two lateral brake lamps is
detected.
The system diagnoses permanently its
capability and may inhibit itself without
specific driver indication, if the system is
outside of the regular operating conditions
(e.g.sensor initialization, board voltage out of
regular range, activation of stability system).
Therefore, the system may not be available
just after starting the vehicle.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
The driver must not overload the vehicle
(keep within the GVW limit and load
height limits for roof bars).
Following an impact (e.g. a collision), the
system is automatically deactivated.
Have it checked by a dealer or a qualified
workshop.
Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
It is configured in the ADAS touch screen
application.
► Select one of the 3 preset
thresholds:"Far","Medium"or"Near".
The selected threshold is memorised when the
ignition is switched off.
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own vehicle
and the object identified for the collision risk, and
the operation of the vehicle (e.g.actions on the
pedals, steering wheel) to trigger the alert at the
most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake!" is displayed.
Level 3: a micro-braking may be given, confirming
the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically at
lower speed.
