Switching off the lighting when switching off the ignition
When the ignition is switched off, all of the lamps switch off immediately, except for the dipped beam headlamps if automatic guide-me-home lighting is activated.
Temporarily keeping the dipped beam headlamps on after the vehicle's ignition has been switched off makes the driver's exit easier when the light is poor.
Switching on
 With the ignition off, "flash" the headlamps using the lighting stalk.  A fur ther "headlamp flash" switches the function off.
Switching off
The manual guide-me-home lighting switches off automatically after a set time.
Manual guide-me-home
lighting
Daytime lighting, compulsory in cer tain countries, which comes on automatically when the engine is star ted making the vehicle more visible to other users.
This function is assured:
- in countries where it is imposed by regulations, by illumination of the dipped beam headlamps associated with illumination of the sidelamps and number plate lamps. - for other countries where it is provided, by illumination of dedicated lamps associated with illumination of the sidelamps and number plate lamps.
The instruments and controls (multifunction screen, air conditioning control panel, ...) are not illuminated, except in night mode with manual or automatic illumination of headlamps.
Daytime running lamps
This function can be activated or deactivated via the vehicle configuration menu.
Switching on the lighting when switching on the ignition
To reactivate the lighting control stalk, turn the ring A to position A"0" - lighting off, then to the position of your choice. If the lighting is switched on manually after
switching off the ignition, there is an audible signal when a front door is opened to warn the driver that they have forgotten to switch off the vehicle's lighting, with the ignition off. They switch off automatically after a period which depends on the state of charge of the battery (entry to energy economy mode).

193Driving
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.
