Comfort
In order for these systems to be fully effective, follow the operation and maintenance guidelines below: )
To obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as wellas the air extractor located in the boot. )
Do not cover the sunshine sensor, located on the dashboard; this is used for regulation of the digital air conditioning system. )
Operate the air conditioning system for at least 5 to 10 minutes, once or twice a monthto keep it in per fect working order. )
Ensure that the passenger compar tment filter is in good condition and have the filter elements replaced regularly. We recommend the use of a combined passenger compartment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by theoccupants and the cleanliness of the passenger compartment (reduction of allergic symptoms, bad odours and greasy deposits).)
To ensure correct operation of the air conditioning system, you are also advised to haveit checked regularly as recommended in the maintenance and warranty guide. )
If the system does not produce cold air, switch it off and contact a CITRO

Driving
The vehicle being followed may not be detected
in cer tain conditions such as, for example:
- when turnin
g,
- when changing lane,
- when the vehicle in front is out of the range
of the sensor (maximum range: around
100 m).
Operating limits
In the event of a fault with the system,
this warning lamp is displayed
accompanied by a message.

Blind spot sensors

A warning lamp appears in the door mirror on
the side in question:


-
immediately, when being over taken,

- after a delay of about one second, whenover taking a vehicle slowly. This drivin
g assistance system warns the driver
of the presence of another vehicle in the blind
spot angle of their vehicle (areas masked from
the driver's field of vision), as soon as thispresents a potential danger.
Sensors fitted in the front and rear bumpersmonitor the blind spots.

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'sresponsibility to constantly check the traffic, to asses the distances and relative speeds of other vehicles and to predict their movements before deciding whether to change lane.
The blind spot sensor system can never replace the vigilance and responsibility of thedriver.

Activation of the system is done in the " Driving assistance
" menu, with the ignition on.

Press this button to activate the
function; the associated indicator lamp comes on.
This indicator lamp comes on in the
instrument panel.

Driving
To deactivate the system, press
this button a
gain; its indicator lamp goes off as well as theassociated indicator in the
instrument panel. In the event of a fault, the warnin
g
lamp flashes then goes off.

Operating fault

Have it checked by a CITROËN dealer or aqualified workshop.
The system is automatically deactivated when towing with a towbar approved by CITROËN.


The system may suffer temporary interference in certain weather conditions (rain, hail...).
In par ticular, driving on a wet surface or moving from a dry area to a wet area can cause false alerts (for example, the presence of a fog of water droplets in the blind spot angle is interpreted as avehicle).
In bad or wintry weather, ensure thatthe sensors are not covered by mud, iceor snow. Take care not to cover the warning zone in the door mirrors or the detectionzones on the front and rear bumpers with adhesive labels or other objects;they may hamper the correct operation of the system. The state o
f the system remains in memory on switching off the ignition.

This system indicates the proximity of an
obstacle (person, vehicle, tree, gate, etc.) which comes within the field of detection of sensorslocated in the bumper.
Certain types of obstacle (stake, roadworkscone, etc.) detected initially will no longer bedetected at the end of the manoeuvre due to
the presence of blind spots.






Parking sensors


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.
Audible assistance
The proximity information is given by anintermittent audible signal, the frequency of whichincreases 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 andthe obstacle becomes less than approximately
thirty centimetres, the audible signal becomescontinuous.

Rear parking sensors


Visual assistance

This supplements the audible signal bydisplaying bars in the screen or the instrument
panel which move progressively nearer to
the vehicle. When the obstacle is near, the"Danger" symbol is displayed.

Front par king sensors

The sound emitted by the speaker (frontor rear) indicates whether the obstacle is in front or behind.
The system will be deactivatedautomatically if a trailer is beingtowed or a bicycle carrier is fitted ona towbar (vehicle fitted with a towbar installed in line with the manufacturer'srecommendations).

In bad weather or in winter, ensure that the sensors are not covered with mud, ice or snow. When reverse gear isengaged, an audible signal (long beep)indicates that the sensors may be dirty.
Cer tain sound sources (motorcycle,lorry, pneumatic drill, etc.) may trigger the audible signals of the parkingsensor system. In addition to the rear parkin
g 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 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).

Deactivation / Activation of thefront and rear parking sensors

The system is deactivated in the " Drivingassistance" menu in the touch screen tablet.


Operating fault

In the event of a malfunction of
