DS 3: Electronic stability control (ESC) / Anti-slip regulation (ASR) / Dynamic stability control (DSC)

Anti-slip regulation (or traction control) optimises traction by using engine braking and by applying the brakes on the driving wheels to avoid one or more wheels spinning. It also enhances the vehicle's directional stability.

If there is a difference between the vehicle’s trajectory and the path desired by the driver, the dynamic stability control system automatically uses engine braking and the brakes on one or more wheels to return the vehicle to the desired path, within the limits of the laws of physics.

These systems are activated automatically every time the vehicle is started.

These systems are activated in the event of a problem with grip or trajectory (confirmed by this warning lamp flashing on the instrument panel).

Deactivation/Reactivation

In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground, etc.), it may be advisable to deactivate the ASR system, so that the wheels can turn freely and regain grip.

Reactivate the system as soon as the level of grip permits.

This function is set via the Driving/Vehicle touch screen menu.

Deactivation is confirmed by the lighting of this indicator lamp on the instrument panel and the display of a message.

The ASR system is reactivated automatically every time the ignition is switched off, or at speeds over 31 mph (50 km/h).

Reactivation is manual below 31 mph (50 km/h).

Malfunction

In the event of a malfunction, this warning lamp comes on on the instrument panel, accompanied by the display of a message and an audible signal.

Have it checked by a dealer or a qualified workshop.

ASR/DSC

These systems enhance safety during normal driving, but should not encourage the driver to take extra risks or drive at high speed. It is in conditions of reduced grip (rain, snow, ice) that the risk of loss of grip increases. It is therefore important for your safety to keep these systems activated in all conditions, and particularly in difficult conditions.

Correct operation of these systems depends on compliance with the manufacturer's recommendations relating to the wheels (tyres and rims), braking and electronic components, as well as the assembly and repair procedures provided by dealers.

In order to ensure that these systems remain effective in wintry conditions, the use of snow or all-season tyres is recommended. All four wheels must be fitted with tyres approved for your vehicle.

All tyre specifications are listed on the tyre/paint label. For more information on Identification markings, refer to the corresponding section.
