DS 3: Driving / Active Lane Departure Warning System

For more information, refer to the General recommendations on the use of driving and manoeuvring aids.

The system corrects the vehicle's trajectory by alerting the driver as soon as it detects a risk of involuntary lane departure or crossing of a verge or hard shoulder (depending on version).

To do this, the system uses a camera, placed on the upper part of the windscreen, identifying the lane markings on the ground and the side of the road (depending on version).

This system is particularly useful on motorways and main roads.

Operating conditions

• Vehicle speed between 43 and 112 mph (70 and 180 km/h).
• Road marked with a central dividing line.
• Steering wheel held in both hands.
• Direction indicators not activated.
• ESC system activated and operational.

The system helps the driver only if there is a risk of the vehicle unintentionally wandering from the lane it is being driven in. It does not manage the safe driving distance, vehicle speed or braking.

The driver must hold the steering wheel with both hands in a way that allows control to be maintained in circumstances where the system is not able to intervene (for example, if the central dividing line disappears).
