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.

Immobilisation, engine running
With the engine running and the vehicle stationary, in order to im-mobilise the vehicle you need to manually apply the parking brake by pulling on control A.
The application of the park-ing brake is confi rmed by :
- the lighting of warning lamp P on control A and on the instrument panel,
- the display of a message “park-ing brake applied” on the multi-function display.
When the driver’s door is opened, a beep is heard and a message displayed if the parking brake has not been applied.
ACTIVATION / DEACTIVATION OF
THE AUTOMATIC FUNCTIONS
The automatic application when the en-gine is switched off and the automatic release when you press the accelerator can be deactivated. Activation / deacti-vation is performed using the Menu of the instrument panel screen. To do so, select “Personalisation/Confi guration / Defi ne the Vehicle parameters / Driving assistance / Automatic handbrake”.
The deactivation of these functions is confi rmed by the lighting of this warning lamp on the instrument panel.
With the automatic functions de-activated, the application and re-lease of the parking brake are done manually.
The full application of the park-ing brake is confi rmed by :
- the extinction of the warning lamp on control A and of warning lamp P on the instrument panel,
- the display of a message “park-ing brake released” on the multi-function display.
Note : If you pull control Awithout pressing the brake pedal, the parking brake will not be released and the “foot on brake” warning lamp will light up on the instrument panel.
E L E C T R O N I C P A R K I N G B R A K E
Before leaving the vehi-cle, check that warning lamp P on the instrument panel is permanently lit.
The deactivation of the automat-ic functions is recommended in particularly cold conditions (ice) and during towing (breakdown, caravan, ...)
MANUAL OPERATION
Manual application / release of the parking brake is always possible.
To start the vehicle
With the ignition on or the engine running, to release the parking brake, press on the brake pedal, pull then release control A.
When stationary, with the engine running, do not press the accelerator pedal unnecessarily, as you may release the parking brake.

To immobilise the vehicle
With the vehicle stationary, to apply the parking brake whether the engine is running or off, pull on control A.
The application of the park-ing brake is confi rmed by :
- the lighting of the warning lamp on control A and of warning lamp P on the instrument panel,
- the display of a message “park-ing brake applied” on the multi-function display.
When the driver’s door is opened with the engine running, a beep is heard and a message displayed if the parking brake has not been applied.
MAXIMUM APPLICATION
If necessary, you can utilise maxi-mum application of the parking brake. It is obtained by means of a long pull on control A, until you see the message “parking brake applied” and a beep is heard.
Maximum application is indispensable :
- in the case of a vehicle towing a caravan or a trailer, if the au-tomatic functions are activated but you are applying the parking brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on a ferry, in a lorry, during towing).
Note :
- In the case of towing, a loaded vehicle or parking on a gradient, turn the front wheels towards the pavement and engage a gear when you park.
- After a maximum application, the release time will be longer.
PARTICULAR SITUATIONS
In certain situations (starting the engine ...), the parking brake can automatically alter its force. This is normal operation.
To advance your vehicle a few centimetres without starting the engine, but with the ignition on, press on the brake pedal and re-lease the parking brake by pull-ing then releasing control A. The full release of the parking brake is confi rmed by the extinction of warning lamp P (red) on the instru-ment panel and the display of a message “parking brake released” on the multifunction display.
If the parking brake malfunctionswhile applied or if the battery runs fl at, an emergency release is always possible (see paragraph “Emergency unlocking”).
