With the engine running and the vehicle stationary, in order to immobilise the vehicle it is essential to manually apply the parking
brake by pulling control lever A .
Immobilising the vehicle,
engine running
The emergency braking must only be used in exceptional circumstances.
Before leaving the vehicle, check that parking brake warning lamp in the instrument panel is on fixed, not flashing.
The application of the parking brake is confirmed by:
- illumination of the braking warning lamp and the P warning lamp in the control lever A ,
- display of the message "Handbrake on".
When the driver’s door is opened, a message is displayed accompanied by an audible signal, if the parking brake has not been applied.
Particular situations
In cer tain situations (e.g. star ting the engine), the parking brake can automatically alter its force. This is normal operation.
To advance your vehicle a few centimetres without star ting the engine, but with the ignition on, press on the brake pedal and release the parking brake by pulling then releasing the control lever A . The full release of the parking brake is confirmed by the warning lamps in the control lever A and in the instrument panel going off and display of the message "Handbrake off ". If the parking brake develops a fault while applied or if the battery runs flat, an emergency release is always possible.
Emergency braking
If a failure of the ESP system is signalled by the illumination of this warning lamp, then braking stability is not guaranteed. In this event, stability must be assured by the driver by repeating alternate "pull-release" actions on the control lever A .
In the event of a failure of the main ser vice brake or in an exceptional situation (e.g. driver taken ill, under instruction, etc) a continuous
pull on the control lever A will stop the vehicle. The electronic stability programme (ESP) provides stability during emergency braking. If the emergency braking malfunctions, the message "Parking brake faulty" will be displayed.

In the event of the electric parking brake malfunctioning or the battery running flat, an emergency manual device can release the parking brake.  Immobilise the vehicle (or keep it stationary, if the brake pedal is pressed), with the engine running, by engaging first gear (manual gearbox) or position M or R(6 -speed electronic gearbox system).
Emergency release
 Switch off the engine but leave the ignition on. If it is not possible to immobilise the vehicle, do not operate the control and contact a CITROËN dealer or a qualified workshop without delay.  Fetch the two vehicle blocks B and the release device C , located under the boot carpet.
 Immobilise the vehicle by placing the blocks in front or behind the two front wheels, opposite to the direction of the slope.  Remove the storage box under the boot carpet for access to the emergency release device.

Driving
 Pierce the protective cover D on the tube Ewith the release device.  Place the release device in the tube.  Turn the release device clockwise . For safety reasons , it is essential to continue turning the device until it reaches its stop. The parking brake is released.  Remove the release device and store it with the blocks in the toolbox under the boot carpet.
For safety reasons, after this operation it is essential to contact a CITROËN dealer or a qualified workshop without delay to replace the protective cover. Following an emergency unlocking, immobilisation of the vehicle is no longer assured once the manual emergency release has been deployed
and the manual control does not allow the re-application of your parking brake.
Take no action, either on the control lever A , or stopping star ting the engine while the release device is engaged. Take care not to allow moisture or dust
in the proximity of the protective cover.
- The operation of the parking brake reinitialises when the ignition is switched off then on again. If the reinitialisation of the parking brake proves impossible, contact a CITROËN dealer or a qualified workshop. - The subsequent time required for application may be longer than during normal operation.

Operation
The system inter venes only when driving economically.
Depending on the driving situation and your vehicle's equipment, the system may advise you to skip one or more gears. You can follow this instruction without engaging the intermediate gears. The gear engagement recommendations must not be considered compulsory. In fact, the configuration of the road, the amount of traffic and safety remain determining factors when choosing the best gear. Therefore, the driver remains responsible for deciding whether or not to follow the advice given by the system. This function cannot be deactivated.
- The system may suggest that you engage a higher gear, if appropriate.
The information appears in the instrument panel screen in the form of an arrow accompanied by the suggested gear.
In the case of driving which makes par ticular demands on the per formance of the engine (firm pressure on the accelerator pedal, for example, when over taking...), the system will not recommend a gear change. The system never suggests: - engaging first gear, - engaging reverse gear, - engaging a lower gear.
* According to engine.
Example:
- You are in third gear.
- You press the accelerator pedal moderately.
