Have the system checked by a CITROËN dealer.
You are recommended to have both Xenon dual-function direction al headlamps changed if there has been a malfunction in either of them.

Whether on dipped beam or main beam, your headlamps follow the direction of the road ahead.

The function can be activated / deactivated in the “Main men u”. See “Multifunction displays”.
When you start the engine, you retain the mode (activated or deactivated) that was selected when you last stopped the engine.

Sensors
The automatic regulation of the air conditioning inside the cabin uses a number of sensors that relieve you of the need to make adjust-ments outside the displayed tem-perature.
Be careful not to obstruct the sun-light sensor located on the dash-board.
Air inlet
Check that the exterior grille for the air inlet, at the bottom of the windscreen, is clean and free of dead leaves, snow, etc.
Air vents
The air vents to the face have grilles and thumbwheels so that you can adjust the air fl ow and direction (up-down, right-left).
Air circulation
Air vents on the fl oor underneath the front seats provide enhanced heating for the rear seat positions : take care not to obstruct them.
Dust fi lter / odour fi lter (active carbon)
There is a fi lter for excluding odours and dust.
This fi lter has to be changed in accordance with the vehicle main-tenance schedule (see the Main-tenance Guide).
Air conditioning
To ensure that your system oper-ates correctly, it is recommended to have it checked regularly.
Water arising from condensation in the air conditioning drains away through a hole provided for this purpose. A pool of water may thus form under the vehicle when sta-tionary.
To keep the air conditioning com-pressor well sealed, it is essential to operate the air conditioning at least once in every month.
To be effective, the air condition-ing should only be used with the windows closed.
If after a lengthy stop in bright sunlight the interior temperature is excessive, ventilate the passen-ger compartment by opening the windows for a few moments, then close them again.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.

QUESTIONSANSWERSSOLUTIONS
The rec eption qualit y of the radio station being listened to gradually deteriorates.
The vehicle is too distant from the transmitter, or no transmitter is present in the geographical area you are passing th rough.
Activate the RDS function to allow the system to chec k whether a more power ful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, underground car parks, etc.) is blocking reception, even in RDS mode.This phenomenon is normal and does not imply anythi ng wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).Have the aerial checked by a CITROËN dealer.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time fo r the radio depends on the batter y charge. The interruption is nor mal: the radio goes into economy mode, cutting off in order to save the vehicle’s batter y.
You have to star t the engine so as to increase the bat-ter y charge.

In order to protect the audio equipment in excessiv e ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
Switch off the audio system for a few minutes in order to allow the system to cool down.
Why is one not informed in real time of a hold-up on the route even though the option for guidance by “traffi c info” is activated ?
When you star t up, the system takes a few minutes to c apture the traf fi c information via RDS-TMC.Wait for the traf fi c information to be safely received (pictogrammes displayed on the map) and make sure that you use the major ar terial roads to have “inform ed” navigation.
Only the major ar terial roads (motor ways and some d ual car-riageways) are featured in RDS-TMC traf fi c information).
It may happen that a hold-up is not repor ted by the tr af fi c info provider.
Why is a diversion not suggested when I have selected traf fi c info ?
Do not confuse the “traf fi c info” guidance option which can sug-gest a diversion (the “diver t” button appears in the w indow) with the menus “Display of traf fi c messages” or “Reading of traf fi c messages” which af fect only the display without recalculating the itinerar y (no “diver t” button in the window).
To have “informed” navigation with the detour proposi-tion, it is essential to activate the guidance option with “traf fi c info”.
