EnglishDriving -> Adaptive Cruise Control for your Citroen C5 Aircross 2017-2025
Driving
With the Stop function, the system manages
the braking until the vehicle stops completely.
With the Stop & Go function, the system
manages the braking until the vehicle stops
completely, and also manages its restarting.
With this button, you can select a memorised
speed setting to use with the speed limiter or
the programmable cruise control.
The system assists the driver in managing
the steering, acceleration and braking
within the limits of the laws of physics
and the capabilities of the vehicle. Some
road infrastructure elements or vehicles
present on the road may not be properly
seen or may be poorly interpreted by the
camera and radar, which may lead to an
unexpected change in direction, a lack of
steering correction and/or inappropriate
management of the acceleration or
braking.
For more information on the Speed limiter or
Cruise control, refer to the associated section.
Highway Driver Assist
This system provides active assistance in
keeping the vehicle in position in its lane.
It associates the Adaptive Cruise Control with
Stop & Go function and Active Lane Keeping
Assist.
To do so, it has a camera located at the top of
the windscreen and, depending on version, a
radar located in the front bumper.
These two functions must be activated and in
operation.
These functions are especially suitable for
driving on motorways and main roads.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
Adaptive Cruise Control
Refer to the General recommendations
on the use of driving and manoeuvring
aids and to Cruise control – particular
recommendations.
For more information on Adaptive Cruise
Control and Active Lane Keeping Assist,
refer to the corresponding sections.
