If you should put in fuel that is not suitable for your vehicle's engine type, it is imperative to have the tank drained be fore you start the engine again.
While you are refuelling, the engine must be stopped and the ignition switched off.
For a petrol engine with a cata-lytic converter, unleaded fuel is compulsory.
The fi ller neck is narrower to ensure that only unleaded petrol can be put in.
When you are seeking to fi ll your tank, do not persist after the third cut-off ; that could cause your vehicle to malfunction.
To open the fl ap, press button A. Undo the cap and attach it to the tab on the inside of the fl ap.Note: The fuel fl ap is locked when you lock your vehicle with the remote control.
FUEL QUALITY
A label inside the fi ller fl ap tells you which type of fuel to use.
The petrol engines are designed to run on RON 95.
However, for better perform-ance (petrol engine), we recom-mend RON 98.

QUESTIONSANSWERSSOLUTIONS
T he 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.
Cutting of sound for 1 to 2 seconds in radio mode.
The RDS system during this brief sound cut- of f is s earching for a better frequency that might of fer improved reception of the station.
Deactivate the RDS function if the phenomenon occur s too frequently and always on the same journey.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time for 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.
The message “ the audio system is overheating” appears on the screen.
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”.
