4. With the engine running, start the compressor by pressing on button A until the tyre pressure reaches 2,0 bars. If you cannot reach a pressure of 2 bars, the tyre is not repairable.5. Remove and store the com-pressor.6. Drive off immediately, for a few miles at reduced speed, to allow the puncture repair to set.7. Adjust the tyre pressure using the compressor according to the recommendations for the vehicle, and check that there is no air escaping (no loss of pressure). If you cannot reach a pressure of 2 bars, the tyre is not repairable.8. Do not exceed 110 km/h (68 mph). The tyre must be examined and repaired by a professional as soon as possible.

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 t h e o p t i o n f o r g u i d a n c e b y “ t r a f fi c i n f o ” is activated ?
When you star t up, the system takes a few minutes to c apture t h e t r a f fi c i n f o r m a t i o n v i a R D S - T M C .
