Citroen C3: Electronic stability control (ESC) / Emergency braking assistance (EBA). Anti-slip regulation (ASR) / Dynamic stability control (DSC)

Emergency braking assistance (EBA)

In an emergency, this system enables you to reach the optimum braking pressure more quickly and therefore reduce the stopping distance.

It is triggered in relation to the speed at which the brake pedal is pressed. This is felt by a reduction in the resistance of the pedal and an increase in braking efficiency.

Anti-slip regulation (ASR) / Dynamic stability control (DSC)

Anti-slip regulation optimises traction using engine braking and by applying the brakes on the driving wheels to avoid wheel spinning. It also enhances the vehicle's directional stability while accelerating.

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.

They come into operation in the event of a grip or trajectory problem.

This warning lamp on the instrument panel flashes to indicate that they are operating.

Deactivation / Reactivation

In exceptional conditions (starting a vehicle stuck in mud, immobilised in snow, on soft ground, etc.), it may be useful to deactivate the ASR system to freely spin the wheels and regain traction.

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

It is set via the Driving / Vehicle touch screen menu.

Deactivation / reactivation is confirmed by the display of a message.

The ASR system is reactivated automatically every time the ignition is switched back on or from 31 mph (50 km/h).

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

Malfunction

In the event of a system malfunction, this warning lamp comes on, accompanied by an onscreen message and audible signal. Contact a CITROËN dealer or a qualified workshop to have the systems checked.

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 used by CITROËN dealers. The use of snow tyres is recommended, to ensure that these systems remain effective in winter conditions. All four wheels must be fitted with tyres approved for the vehicle.
