Parking space sensors
System which measures the parking space available between two vehicles or obstacles. It measures the size of the space and gives you information on: - the possibility of fitting into a free space,
depending on the dimensions of your vehicle and the distances needed for manoeuvring, - the level of difficulty of the manoeuvre to be per formed. The system does not measure spaces which
are clearly much smaller or larger than the size of the vehicle.
Displays in the instrument panel You have identified a parking space:  Press button A to select the function.  Operate the direction indicator on the side where the space is to be measured; a message is displayed to confirm that measurement is in progress.  During measurement, go for ward the length of the space, at a speed less than 12 mph (approx. 20 km/h), to prepare for your manoeuvre.  Once the measurement has been completed, the system informs you of the level of difficulty of the manoeuvre by a message in the multifunction screen
accompanied by an audible signal.
Operation
The parking space sensor function warning lamp can have two different states:
- on fixed: the function is selected by a press on control A . - off: the function is not selected,

The function displays the following types of message: The function deselects itself automatically: - when you engage reverse gear, - when you switch off the ignition, - if measuring is not requested,
- within five minutes of selection of the function, - if the vehicle speed exceeds the threshold of 45 mph (approx. 70 km/h) for one minute.
If the lateral distance between your vehicle and the parking space is too large, the system may not be able to measure the space.
The system remains available after each measurement and can therefore measure several spaces in succession. In poor or wintry weather, ensure that the
sensors are free of dir t, ice or snow. The parking space sensor system deactivates the front parking sensors when measuring for wards.

Parking sensors
This system indicates the proximity of an obstacle (person, vehicle, tree, gate, etc.) which comes within the field of detection of sensors located in the bumper.
Cer tain types of obstacle (stake, roadworks cone, etc.) detected initially will no longer be detected at the end of the manoeuvre due to
the presence of blind spots.
This function cannot, in any circumstances, take the place of the vigilance and responsibility of the driver.
The system is switched on by engaging reverse gear. This is accompanied by an audible signal. The system is switched off when you exit reverse gear.
Rear parking sensors
Audible assistance
The proximity information is given by an intermittent audible signal, the frequency of which increases as the vehicle approaches the obstacle. The sound emitted by the speaker (right or left) indicates the side on which the obstacle is located. When the distance between the vehicle and the obstacle becomes less than approximately thir ty centimetres, the audible signal becomes continuous.
Visual assistance
This supplements the audible signal by displaying bars in the multifunction screen which move progressively nearer to the vehicle. When the obstacle is near, the "Danger" symbol is also displayed in the screen.

Operating fault
If an operating fault occurs, when reverse gear is engaged this warning lamp is displayed in the
instrument panel and/or a message appears in the screen, accompanied by an audible signal (shor t beep). Contact a CITROËN dealer or a qualified workshop.
In addition to the rear parking sensors, the front parking sensors are triggered when an obstacle is detected in front and the speed of the vehicle
is still below 6 mph (10 km/h). The sound emitted by the speaker (front or rear) indicates whether the obstacle is in front or behind. The front parking sensors are interrupted if the vehicle stops for more than three seconds in for ward gear, if no fur ther obstacles are detected or when the speed of the vehicle exceeds 6 mph (10 km/h).
The function will be deactivated automatically if a trailer is being towed or a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear is engaged, an audible signal (long beep) indicates that the sensors may be dir ty. When the vehicle is moving at a speed below 6 mph (10 km/h), cer tain sound sources (motorcycle, lorry, pneumatic drill, etc.) may trigger the audible signals of the parking sensor system.
Deactivation/Activation of the front and rear parking sensors
The function is deactivated by pressing this button. The indicator lamp in the button
comes on. Pressing this button again reactivates the function. The indicator lamp in the button goes off.

Bonnet
Opening
 Open the front left door.  Pull the interior bonnet release lever A , located at the bottom of the door aper ture.
 Push the exterior safety catch B to the left and raise the bonnet.  Unclip the stay C from its housing.  Fix the stay in the notch to hold the bonnet open.
The location of the interior bonnet release lever prevents opening of
the bonnet while the front left door is closed.
When the engine is hot, handle the exterior safety catch and the bonnet stay with care (risk of burns).
Before doing anything under the bonnet, switch off the Stop & Star t
system to avoid any risk of injury resulting from an automatic change to START mode.

 Fill the fuel tank with at least five litres of diesel.  Open the bonnet.  Squeeze and release the priming pump repeatedly until it hardens (it may be hard at the first press).  Operate the star ter until the engine star ts.  Close the bonnet.
If the engine does not star t first time, don't keep trying. Operate the priming pump again, then the star ter motor.
 Take the stay out of the suppor t notch.  Clip the stay in its housing.  Lower the bonnet and release it at the end of its travel.  Pull on the bonnet to check that it is secured correctly.
2 litre Turbo HDI engine
