CITROEN C5 AIRCROSS Handbook page 159

The system also takes motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road
are not necessarily detected.
This system is comprised of three functions:
- Collision Risk Alert,
- Intelligent emergency braking assistance,
- Active Safety Brake (automatic emergency
braking).
The vehicle has a multifunctional camera
located at the top of the windscreen, and,
depending on version, a radar located in the
front bumper.
As soon as the system detects a potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically
activated at every engine start.
This system can be deactivated or
activated via the Driving/Vehicle
menu of the touch screen.
Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a message.
Operating conditions and
limits
The ESC system must not be faulty.
The DSC/ASR systems must not be
deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
- towing a trailer,
- carrying long objects on roof bars or roof
rack,
- with snow chains fitted,
- before using an automatic car wash, with
the engine running,
- before placing the vehicle on a rolling road
in a workshop,
- towed vehicle, engine running,
- damaged front bumper (version with radar),
- following an impact to the windscreen close
to the detection camera.
The system is automatically deactivated
after the use of certain "space-saver"
type spare wheels is detected (smaller
diameter).
The system is automatically deactivated
after detection of a fault with the brake
pedal switch or with at least two brake
lamps.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.
