engine Citroen DS5 HYBRID4 2014 1.G Repair Manual

A set of the following Electronic Stability systems: - anti-lock braking system (ABS) and electronic brake force distribution (EBFD), - emergency braking assistance, - wheel anti-slip regulation (ASR) or traction control, - dynamic stability control (DSC).
Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS) and electronic brake force distribution (EBFD)
This system improves the stability and manoeuvrability of your vehicle when braking and provides improved control in corners, in particular on poor or slippery road sur faces. The ABS prevents wheel lock in the event of emergency braking. The electronic brake force distribution system manages the braking pressure wheel by wheel.
Emergency braking assistance
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 the effectiveness of the braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to avoid wheel slip by acting on the brakes of the driving wheels and on the engine. It also improves the directional stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed by the vehicle and that required by the driver, the DSC monitors each wheel and automatically acts on the brake of one or more wheels and on the engine to return the vehicle to the required path, within the limits of the laws of physics.

Dynamic stability control (DSC) and anti-slip regulation (ASR)
Activation
These systems are activated automatically each time the vehicle is started. As soon as they detect a problem of grip or trajectory, these systems act on the operation if the engine and brakes.
This is indicated by flashing of this warning lamp in the instrument panel.
Deactivation
In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the DSC and ASR, so that the wheels can turn freely and regain grip.
Operating fault
Illumination of this warning lamp and the lamp in the deactivation button, accompanied by an audible signal and a message, indicate a fault with the system.
Reactivation
The systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h). Below 30 mph (50 km/h), you can reactivate them manually:
 Press this button.
The indicator lamp in the button comes on. The DSC and ASR systems no longer act on the operation of the engine and on the brakes in the event of a involuntary change of trajectory.
 Press this button again. Reactivate the systems as soon as the level of grip permits.
Contact a CITROËN dealer or a qualified workshop to have the system checked.
