DS 3: Adaptive Cruise Control / Operating limits. Malfunction

Operating limits

Cruise control operates by day and night, in dry weather or moderate rainfall.

Certain situations cannot be managed by the system and require driver intervention.

Cases not taken into account by the system:

• Pedestrians, cyclists, animals.
• Stationary vehicles (e.g. traffic jams, breakdown).

• Vehicles crossing your lane.
• Vehicles driving in the opposite direction.

Situations where the driver must suspend the system:

• Vehicles in a tight bend.
• When approaching a roundabout.

• When following a narrow vehicle.

Reactivate the system when conditions allow.

Situations in which the driver is prompted to immediately resume control:

• Excessively sharp deceleration by the vehicle in front of you.

• When a vehicle cuts in sharply between your vehicle and the one in front.

Some vehicles on the road may be poorly perceived or interpreted by the camera and/or the radar (e.g. truck), which can lead to an incorrect evaluation of distances and result in inappropriate acceleration or braking of the vehicle.

Pay particular attention:

• When motorcycles are present and when there are vehicles staggered across the traffic lane.
• When entering a tunnel or crossing a bridge.

If any of the following malfunctions occurs, do not use the system:

• Following an impact on the windscreen close to the camera or on the front bumper (versions with radar).
• Brake lamps not working.

If the vehicle has undergone any of the following modifications, do not use the system:

• Carrying long objects on roof bars.
• Towing.
• Front end of the vehicle modified (for example by adding long-range headlamps or painting the front bumper).
• Obstructed radar.

Malfunction

In the event of a malfunction, dashes are displayed instead of the speed setting.

This warning lamp comes on, accompanied by a message and an audible signal, to confirm the malfunction.

Have it checked by a dealer or a qualified workshop.
