IIABS - Anti-lock braking system
This system enhances your safety by preventing the wheels from locking under heavy braking or in conditions of poor road adherence.
It enables you to retain control of the steering.
The operating capacity of all the electrical components that are essential to the ABS system is checked by an electrical monitoring system before and during your journey. The ABS warning lamp comes on when you switch on the ignition and should go out after a few seconds.
If the warning lamp does not go out, this means that the ABS has discon-nected as a result of a malfunction. Also, if the warning la mp lights up dur-ing a journey, it means that the ABS system is inactive. In eith er case, the normal braking system remains fully effective, as on a non-ABS vehicle.
However, to restore the safety associated with the correct operat ion of the ABS, the vehicle should be examined as soon as possible by a CITR OËN However, to restore the safety associated with the correct operation of the operation of the
dealer.
On slippery surfaces (gravel, snow, ice, etc.), driving carefully is sti ll es-sential.
Emergency braking assistance system
In an emergency, this system enables you to achieve the optimum braking pressure more quickly, thereby reducing the stopping distance. It deploys according to the speed of your action on the brake pedal, reducing the resistance to that action.
To prolong the effect of the emergency braking assistance, simply keep your foot on the brake pedal.

State of wear of brake pads, discs and drums
Brake pad wear varies according to the way you use your vehicle (e.g. urban driving, frequent stops, your style of driving or the type of road).For all information relating to the checking of the state of wear of brake discs and drums, contact a CITROËN dealer.brake discs and drums, brake discs
After washing, apply the brakes gradually to remove water from the brake linings.

SAFETY RECOMMENDATIONS
The ESP system offers increased driving safety but is not in place to encourage the driver to take addi-tional risks or to drive at excessive speeds.
The functioning of this system is subject to compliance with the manufacturer’s recommendations on wheels (tyres and rims), brake parts and electronic components, as well as with CITROËN’s as-parts and electronic components, components,
sembly and repair procedures.
After any collision, have this system checked by a CITROËN dealer.After any collision, have this system , have t
Electronic stability programme (ESP) and traction control (ASR)
These systems are closely connected to the ABS and additional to it. In the event of a loss of control of the vehicle by the driver, the ESP system acts automatically on one or more brakes and also on the engine to bring the vehicle back on trajectory. The ASR system optimises traction and prevents wheel spin by acting on the brakes of the driving wheels, as well as on the engine. It also improves steering stability during acceleration.
Operation :
When either the ESP or ASR system is in operation, the ESP/ASR warning lamp fl ashes.
Deactivation
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may prove useful to deactivate the ESP/ASR system to allow the wheels to spin and thus regain traction.
- Press on control A, the ESP/ASR warning lamp and the control light up. The ESP/ASR systems are no longer active.
The ESP/ASR systems will activate again :
- Automatically after the ignition has been switched off.
- Automatically above a speed of 50 km/h (30 mph).
- Manually with a new press on control A.
Operational anomaly
If the systems malfunction, the ESP/ASR warning lamp comes on, ac-companied by a sound signal and a message on the multifunction display. Contact a CITROËN dealer to have the system checked.companied by a sound signal and a message on the multifunction by a sound

Any repair or any change of tyre, on a wheel fi tted with a sensor, should be carried out by a CITROËN dealer.Any repair or any change of tyre, on a wheel fi tted with a sensor, Any repair or any change of tyre, on a wheel fi tted with a sensor,
The system may be affected from time to time by interference from radio transmissions on similar frequencies.
This function alerts you in the event of a tyre being defl ated or punctured. For this purpose, sen-sors continuously monitor the con-dition of the vehicle’s wheels.
This system does not absolve the driver of the need to check the tyre pressures regularly.
T Y R E D E F L A T I O N D E T E C T I O N
The SERVICE warning lamp comes on and a ve-hicle outline is displayed, accompanied by a mes-sage and a sound signal. The wheel(s) concerned will be shown fl ashing on the vehicle outline. Check the tyre pressures as soon as possible.
Defl ation warning
The STOP warning lamp comes on and a vehicle outline is displayed, ac-companied by a mes-sage and a sound signal. The wheel(s) concerned will be shown fl ashing on the vehi-cle outline. Stop the vehicle imme-diately, avoiding any violent actions on the steering wheel or brakes.
Puncture
Change the damaged wheel (whether punctured or substan-tially defl ated), have the tyre re-paired as soon as possible, then check the tyre pressures as soon as you can after that.
The wheel affected will no longer be detectable by the alert system if it is in the boot or undergoing re-pair. The spare wheel is not moni-tored by the alert system.
The SERVICE warning lamp comes on and a vehicle outline is dis-played, accompanied by a message and a sound signal. The wheel(s) concerned will be shown as ab-sent on the vehicle outline. If you have not changed a wheel, this in-formation indicates a malfunction-ing of the system.
Consult the CITROËN network to have the defective sensor(s) re-placed.
Wheel not monitored
The defl ation detection system is a driving assistance function which does not relieve the driver from the responsibility to be vigilant.
This system does not absolve the driver of the need to check the tyre pressures on a regular basis (see “Vehicle identifi cation»), to ensure that the vehicle behaves as it should and to avoid prema-ture wear on the tyres, especially when the vehicle is being subject-ed to heavy loads or driven at high speeds.
Do not forget to check the tyre pressure on the spare wheel.
