2013.5 Citroen DS5 HYBRID4 RHD brakes

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.

245Practical information
We recommend the use of genuine CITROËN towbars and their harnesses that have been tested and approved from the design stage of your vehicle, and that the fitting of the towbar is
entrusted to a CITROËN dealer or a qualified workshop. If the towbar is not fitted by a CITROËN dealer, it is imperative that it is fitted in accordance with the vehicle manufacturer's instructions.
Driving advice
Distribution of loads
 Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight approaches the maximum permitted without exceeding it. Air density decreases with altitude, thus
reducing engine performance. Above 1 000 metres, the maximum towed load must be reduced by 10 % for every 1 000 metres of altitude.
Side wind
 Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.  To lower the engine speed, reduce your speed.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off the engine as soon as possible.
Braking
Towing a trailer increases the braking distance. To avoid overheating of the brakes on a long mountain type of descent, the use of engine braking is recommended.
Ty r e s
 Check the tyre pressures of the towing vehicle and of the trailer, observing the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
The rear parking sensors will be deactivated automatically if a genuine CITROËN towbar is used.
Driving with a trailer places greater demands on the towing vehicle and the driver must take particular care.
The maximum towed load on a long incline depends on the gradient and the ambient temperature. In all cases, keep a check on the coolant temperature.
Refer to the "Technical data" section for details of the weights and towed loads which apply to your vehicle.

Electronic gearbox
The gearbox does not require any maintenance (no oil change). Refer to the maintenance and warranty guide for details of the checking interval for this component.
Brake wear depends on the style of driving, particularly in the case of vehicles used in town, over short distances. It may be necessary to have the condition of the brakes checked, even between vehicle services. Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
Brake pads
For information on checking brake disc wear, contact a CITROËN dealer or a qualified workshop.
Brake disc wear
Electric parking brake
This system does not require any routine servicing. However, in the
event of a problem, have the system checked by a CITROËN dealer or a qualified workshop.
Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operation of units as important as those in the braking system, CITROËN selects and offers very specific products. After washing the vehicle, dampness, or in wintry conditions, ice can form on the brake discs and pads: braking efficiency may be reduced. Make light brake applications to dry and defrost the brakes.
For more information, refer to the "Electric parking brake - Operating faults" section.
