Safety
Seat belt unfastened warning lamp
This warning lamp comes on in the instrument panel when one or more rear passengers unfasten their seat belt. From approximately 12 mph (20 km/h), this warning lamp flashes for two minutes accompanied by an audible signal of increasing volume. Once these two minutes have elapsed, this warning lamp remains on until the one or more rear passengers fasten their seat belt.
Seat belt unfastened warning lamps display
3. Rear right seat belt warning lamp. 4. Rear centre seat belt warning lamp. 5. Rear left seat belt warning lamp. When the ignition is switched on, with the engine running or when the vehicle is moving at less than 12 mph (20 km/h), the corresponding warning
lamps 3 , 4 and 45 come on in red for approximately 30 seconds, if the seat belt is not fastened. When the vehicle is moving at more than 12 mph
(20 km/h), the corresponding warning lamps 3 , 4 and 5 come on in red, accompanied by an audible signal and a message in the screen, if a rear passenger has unfastened their seat belt.

Lateral airbags
System which protects the driver and front passenger in the event of a serious side impact in order to limit the risk of injury to the chest, between the hip and the shoulder. Each lateral airbag is fitted in the seat backrest frame, door side.
Deployment Impact detection zones
A. Front impact zone. B. Side impact zone.
The lateral airbags are deployed unilaterally in the event of a serious side impact applied to all or par t of the side impact zone B , perpendicular to the longitudinal centreline of the vehicle on a horizontal plane and directed from the outside towards the inside of the vehicle. The lateral airbag inflates between the hip and
shoulder of the front occupant of the vehicle and the corresponding door trim panel.

185Safety
Curtain airbags
System which protects the driver and passengers (with the exception of the rear centre passenger) in the event of a serious side impact in order to limit the risk of injury to the side of the head. Each cur tain airbag is built into the pillars and the upper passenger compar tment area.
Deployment
The cur tain airbag is deployed at the same time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t of the side impact zone B , perpendicular to the longitudinal centreline of the vehicle on a horizontal plane and directed from the outside towards the inside of the vehicle. The cur tain airbag inflates between the front or rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be deployed. In the event of a rear or front collision, the airbag is not deployed.
If this warning lamp comes on in the instrument panel, accompanied by an audible signal and a message in the screen, contact a CITROËN dealer or a qualified workshop to have the system checked.
The airbags may no longer be deployed in the event of a serious impact.

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.

Gear shift indicator * System which reduces fuel consumption by advising the driver to change up on vehicles fitted with a manual gearbox.
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.

209Driving
Lane departure warning system
System which detects the involuntary crossing of longitudinal traffic lane markings on the ground (solid or broken line). Sensors, fitted below the front bumper, trigger a warning if the vehicle drifts over a lane marking (speed higher than 50 mph (80 km/h)). This system is par ticularly useful on motor ways
and main roads.
Activation
 Press this button, the indicator lampcomes on.
The lane depar ture warning system cannot, in any circumstances, replace the need for vigilance and responsibility on the par t of the driver.
Deactivation
You are warned by the vibration of the driver's seat cushion: - on the right-hand side, if the marking on the ground has been crossed on the right, - on the left-hand side, if the marking on the
ground has been crossed on the left. No warning is transmitted while the direction indicator is active and for approximately20 seconds after the direction indicator is switched off. A warning may be transmitted if a direction marking (e.g. arrow) or non-standard marking (e.g. graffiti) is crossed.
Detection
Operating fault
The detection may be impeded: - if the sensors are dir ty (mud, snow...), - if the markings on the ground are worn, - if there is little contrast between the markings on the ground and the road sur face.
 Press this button again, the indicator lamp goes off. The status of the system remains in the memory when the ignition is switched off.
In the event of a malfunction, the ser vice warning lamp comes on, accompanied by an audible signal and a message in the screen. Contact a CITROËN dealer or a qualified workshop.

Blind spot sensors
of the presence of another vehicle in the blind spot angle of their vehicle, as soon as this presents a potential danger.
Operation
This system is designed to improve safety when driving and is in no circumstances a substitute for the use of the interior rear view mirror and door mirrors. It is the driver's responsibility to constantly check the traffic, to ass es the distances and relative speeds of other vehicles and to predict their movements before de ciding whether to change lane. The blind spot sensor system can never replace the vigilance and responsibility of the driver.
 On switching on the ignition, or engine running, press this button to activate the function; the warning lamp comes on.
Sensors fitted in the front and rear bumpers monitor obscured zones in the driver's field of vision.
A warning lamp appears in the door mirror on the side in question: - immediately, when being over taken, - after a delay of one second, when over taking another vehicle too slowly.

System which prevents the vehicle from exceeding the speed programmed by the driver. When the programmed speed limit is reached, pressing the accelerator pedal no longer has any effect.
Speed limiter
The speed limiter cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the part of the driver.
The functions of this system are grouped together on the steering mounted controls. 1. Speed limiter mode selection dial. 2. Programmed value decrease button. 3. Programmed value increase button. 4. Speed limiter on/off button. 5. List of memorised speeds display button. (see "Memorising speeds")
Steering mounted controls
The programmed information is grouped together in the instrument panel screen. 6. Speed limiter on/off indication. 7. Speed limiter mode selection indication. 8. Programmed speed value. 9. Selection of a memorised speed. (see "Memorising speeds")
Displays in the instrument panel
Operation
The speed limiter is switched on manually: it requires a programmed speed of at least20 mph (30 km/h). The speed limiter is switched off by manual d offoperation of the control. The programmed speed can be exceeded temporarily by pressing the accelerator firmly beyond the point of resistance. To return to the programmed speed, simply release the accelerator pedal. The programmed speed remains in the memory when the ignition is switched off.

215Driving
 Turn dial 1 to the "LIMIT" position: the speed limiter mode is selected but is not switched on (Pause). You do not have to switch the speed limiter on
in order to set the speed.  Set the speed value by pressing button 2or 3 (e.g.: 55 mph (90 km/h)).
Programming
You can then change the programmed speed using buttons 2 and 3 : - by + or - 1 mph (km/h) = shor t press, - in steps of + or - 5 mph (km/h) = maintained press. If speed memorisation is available and activated on your vehicle, the programmed speed will stop at the closest memorised speed; refer the the corresponding paragraph.  Switch the speed limiter on by pressing button 4 .  Switch the speed limiter off by pressing button 4 : the display confirms that it has been switched off (Pause).  Switch the speed limiter back on by pressing button 4 again.
Exceeding the programmed speed
Pressing the accelerator pedal to exceed the programmed speed will not have any effect unless you press the pedal firmly past the mlypoint of resistance . The speed limiter is deactivated temporarily and the programmed speed,
which is still displayed, flashes. Returning to the programmed speed, by means of inten tional or unintentional deceleration of the vehicle, automatically cancels the flashing of the programmed speed.
On a steep descent or in the event of sharp acceleration, the speed limiter will not be able to prevent the vehicle from
exceeding the programmed speed. To avoid any risk of jamming of the pedals: - ensure that the mat is positioned correctly, - do not fit one mat on top of another.
Exiting the speed limiter mode
 Turn dial 1 to the "0" position: the speed limiter mode is deselected. It disappears from the screen.
Operating fault
In the event of a fault with the speed limiter, the speed is cleared resulting in flashing of the dashes. Have it checked by a CITROËN dealer or a qualified workshop.
