Proximity sensors are located in the front and rear bumpers of your vehicle.
When manoeuvring, whether forwards or in reverse, at a speed below approx. 6 mph, they warn you of the presence of any obstacle situated within their detection zone, by means of:
- a sound signal emitted by the front or rear loudspeakers,
- the display of the outline of your vehicle with shading at the zones where obstacles are detected.
As the vehicle approaches an obstacle, the sound signal tells you its position according to whether the sound issues from the front LH or RH speaker or from the rear LH or RH speaker.
NaviDrive version
Screen C version
- As the vehicle gets close to the obstacle, the sound signal becomes ever more rapid and the shading appears ever closer to your vehicle’s outline.
- When the obstacle is less than around 25 centimetres from the vehicle, the signal becomes continuous and a WARNING panel appears on the display.

- Moving forward at a speed lower than approx. 10 km/h (6 mph), either in neutral or in a gear, the outline of your vehicle is displayed on the screen immediately an obstacle is detected in front of the vehicle. Obstacles situated at the front of the vehicle can be detected.
When selecting reverse gear, a short audible sig-nal followed by another audible signal, accom-panied by the illumination of the SERVICE warning lamp indicates a malfunction of the system.
Consult a CITROËN dealer.
Note
- The proximity sensors cannot detect obstacles situated immediately below or above the bumpers.
- A thin object such as a spike or stake, or other similar object, may be detected only at the start of your manoeuvre but not when the vehicle has approached close to it.
- During the winter months or in bad weather, make sure that the sensors are not covered by dirt or by ice or snow.
