Warning / indicator lampStateCauseAction / Observations
Dynamic stability control (DSC/ASR)
flashing. The DSC/ASR regulation is operating. The system optimises traction and improves the directional stability of the vehicle in the event of loss of grip or trajectory.
fixed. The DSC/ASR system has a fault. Have it checked by a CITROËN dealer or a qualified workshop.

Engine autodiagnosis system
flashing. The engine management system has a fault. Risk of destruction of the catalytic converter. Have it checked by a CITROËN dealer or a qualified workshop.
fixed. The emission control system has a fault. The warning lamp should go off when the engine is started. If it does not go off, contact a CITROËN dealer or qualified
workshop without delay.

Anti-lock Braking System (ABS)
fixed. The anti-lock braking system has a fault. The vehicle retains conventional braking. Drive carefully at reduced speed and contact a CITROËN dealer or a qualified workshop without d e l ay.

Braking fixed. The braking system fluid level has dropped significantly. You must stop as soon as it is safe to do so. Top up with brake fluid listed by CITROËN. If the problem persists, have the system checked by a CITROËN dealer or a qualified workshop.
+ fixed, associated with the ABS warning lamp.
The electronic brake force distribution (EBFD) system has a fault. You must stop as soon as it is safe to do so. Have it checked by a CITROËN dealer or a qualified workshop.

The various caps and covers allow access for checking the levels of the various fluids, for replacing certain components and for priming the fuel system.

Before doing anything under the bonnet, switch off the ignition ( Readylamp off) to avoid any risk of injury resulting from automatic operation of the engine.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
Brake fluid level
Changing the fl uid
Refer to the maintenance and warranty guide for details of the interval for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations.
The power steering fluid level should be close to the "MA X" mark. With the engine cold, unscrew the cap to check the level.
Power steering fluid level
Coolant level
The coolant level should be close to the "MA X" mark but should never exceed it.
When the engine is warm, the temperature of the coolant is regulated by the fan.
In addition, as the cooling system is pressurised, wait at least one hour after switching off the engine before carrying out any work. To avoid any risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Fluid specifi cation
The coolant must conform to the manufacturer's recommendations.
The cooling fan may star t after switching off the engine: take care with ar ticles and clothing that might become caught by the fan blades.

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.
