III
The programmable heating sys-tem operates independently of the engine.
With the engine off, it is used to preheat the engine cooling system so as to have an optimum engine operating temperature on starting.
The programmable heating sys-tem is started using a long-range remote control. It can be started immediately or programmed to start later.
In the event of a malfunction of the programmable heating sys-tem, contact a CITROËN dealer.the programmable heating sys-programmable heating

Replacing the battery
The remote control is powered by a 6V-28L battery cell, which is included.
Information appears on the screen when this battery should be replaced.
Unclip the casing and replace the battery.
The remote control must then be re-initialised, as described on this page.
Do not discard old batteries; take them to an approved recycling point.
Re-initialisation of the remote control
Always switch off the program-mable heating while refuelling in order to avoid the risk of fi re or explosion.
To avoid the risk of intoxication or asphyxiation, the program-mable heating should not be used, even for a short time, in an enclosed space such as a garage, or workshop without exhaust gas extraction.
Do not park the vehicle over infl ammable materials (dry grass, dead leaves, papers…), as there is a risk of fi re.
The programmable heating sys-tem is supplied by the vehicle’s fuel tank. Before using it, ensure that there is suffi cient fuel in the tank. If the low fuel warning lamp is on we strongly recommend that you do not programme the heating to come on.
P R O G R A M M A B L E H E A T I N G
If the battery is disconnected or replaced, the remote control must be re-initialised.
After switching on, within fi ve sec-onds press button 4 (OFF) for 1 second.
If the operation is successful, the "OK" message appears in the remote control screen.
If not, the "FAIL" message appears. Repeat the procedure.
As a secondary advantage, use of your programmable heating sys-tem allows it to be used to pre-heat the passenger compartment

The particular radio station is not in the regional t raffi c information network.Change to a radio station that does broadcast traffi c information.
The reception quality 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 a re passing through.
Activate the RDS function to allow the system to check whether a more power ful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, under-ground car parks, etc.) is blocking reception, even in RDS mode.
This phenomenon is normal and does not imply anything 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 for the radio depends on the battery charge. The interruption is normal.: the radio goes into economy mode, cutting of f in order to save the vehicle’s battery.
You have to start the engine so as to increase the battery charge.
The message "the audio system is overheating" appears on the screen.
In order to protect the audio equipment in excessive 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.

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.

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”.
