The trafﬁ c announcement (TA) is displayed. I do not receive any trafﬁ c information.
Tune to a radio station which broadcasts trafﬁ c information. The radio station is not part of the regional trafﬁ c information network.
QUESTION SOLUTION ANSWER
The quality of reception of the radio station listened to gradually deteriorates or the stored stations do not function (no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used b y the station listened to or there is no transmitter in the geographical area th rough which the vehicle is travelling.
The environment (hills, buildings, tunnels, baseme nt car parks...) block reception, including in RDS mode.
The aerial is absent or has been damaged (for exam ple when going through a car wash or into an underground car park).
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
This phenomenon is normal and does not indicate a failure of the audio equipment.
Have the aerial checked by a CITROËN dealer.
Sound cut-outs of 1 to 2 seconds in radio mode.
During this brief sound cut-out, the RDS searches for any frequency permitting better reception of the station. Deactivate the RDS function if the phenomenon is too frequent and always on the same route.
With the engine off, the audio equipment switches off after afew minutes of use.
When the engine is switched off, the audio equipme nt operating time depends on the battery charge. The switch-off is normal: the audio equipment switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
The stored stations do not function (no sound, 87.5 Mhz is displayed...).
An incorrect waveband is selected. Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on whichthe stations are stored.
The message "the audio system is overheated" appears on the display.
Switch the audio system off for a few minutes to allow the system to cool. In order to protect the installation if the surrounding temperature is too high, the audio equipment switches to an automatic thermal protection mode leading to a reduction of the volume or stopping of the playing of the CD.
