DS 3: Lane positioning assist / Cruise control. Pausing/Suspending the system

Cruise control

The driver must hold the steering wheel properly. When cruise control is activated, the symbol is displayed in green: by small steering actions, the system directs the vehicle and keeps it in the position chosen by the driver, in the traffic lane.

This position is not necessarily the centre of the lane.

The driver can feel movements in the steering wheel.

The driver can change the position of the vehicle at any time, by turning the steering wheel, which suspends the function. The driver positions the vehicle where they wish to in the lane. When the driver feels that the vehicle’s position is appropriate, they maintain it until the function is reactivated. The system regains control by regulating on the new defined position.

Pausing/Suspending the system

The driver must act promptly if they believe that the traffic conditions or the state of the road surface require their intervention, by moving the steering wheel to temporarily suspend system operation. Any intervention on the brake pedal that causes the Adaptive Cruise Control to pause will also cause the system to pause.

If the system detects that the driver is not holding the wheel firmly enough, it triggers a series of gradual alerts and then deactivates itself if there is no response from the driver.

If the function is suspended due to the prolonged release of the force holding the steering wheel, the function must be reactivated by pressing the button again.

Automatic pause

• Triggering of the ESC.
• Prolonged failure to detect one of the lane limit markings. In this case, the Active Lane Departure Warning System function can take over, and the system will reactivate itself once the operating conditions are met again.

In response to action by the driver: suspension

• Activation of the direction indicators.
• Travelling outside the lane limits.
• Too tight a grip on the steering wheel or dynamic action on the steering wheel.
• Action on the brake pedal (resulting in a pause until cruise control is reactivated) or accelerator pedal (suspension for as long as the pedal is depressed).
• Pausing of Adaptive Cruise Control.
• Deactivation of the ASR.
