The value appears immediately on the
instrument panel. Using a radar with a range of about 100
metres,
located at the front of the vehicle, this system
detects a vehicle travelling in front of your
vehicle.
It automatically adjusts the speed of your
vehicle to that of the vehicle in front.
If the vehicle in front is running more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the " -" b u t to n).
If your vehicle is too close to the vehicle in
front or is approaching it too quickly, adaptive
cruise control is automatically deactivated.
The driver is then alerted by an audible signal
accompanied by a message.
If the vehicle in front accelerates or changes
lane, the adaptive cruise control gradually
accelerates your vehicle to return to the
programmed speed.
If the driver operates a direction indicator to
overtake a slower vehicle, the adaptive cruise
control allows your vehicle to temporarily
approach the vehicle in front to assist the
overtaking manoeuvre, though never exceeding
the programmed speed.

In the following cases, deactivating the
system via the vehicle's configuration menu is
recommended:
-

hen towing a trailer or caravan,
-
w

beyond the windscreen (for example: long
objects),
-
w
hen the vehicle is being towed, with the

i
f the brake lamps are not working. Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified. Consequently, always stay
alert and be prepared to react at any time
to avoid an accident.Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen, different levels of alert can be
triggered and displayed in the instrument panel
or the head-up display.
This information also appears in the
head-up display. For more information
on the Head-up display, refer to the
corresponding section.
Level 1 : visual alert only, warning
you that the vehicle ahead is very
close.
A message is displayed warning you
to be vigilant when approaching the
target vehicle. This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
A message indicating that you
should brake is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.
After an impact, the function automatically
stops operating. Consult a CITROËN
dealer or a qualified workshop to have the
system checked.
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.
Furthermore, the level 1
alert is never
displayed with the " Close" threshold.
