Get Driving -> Adaptive Cruise Control Guide for Citroen C5 SUV 2020

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.

This system automatically maintains the

speed of your vehicle at a value which you set

(speed setting), while keeping a safe distance

from the vehicle in front (target vehicle), and

which has been set beforehand by the driver.

The system automatically manages the
