To stop the function
- move the control from position "LIM" to position 0.
- or stop the engine.
The speed that you chose is memorised.
In the event of a malfunction, a message is displayed, accompanied by a sound signal and lighting of the SERVICE warning lamp.
Consult your CITROËN dealer.
A fl oor mat not recom-mended by CITROËN risks sliding under the accelerator pedal, thus preventing you from pressing past the tight spot.
It will then be impossible to exit from the desired limitation, unless by acting on the steering wheel control.
The driver must still remain attentive and in complete control of the vehicle.
We advise the driver to keep their feet close to the pedals.
Note: if during speed limitation, the system cannot keep to the maximum speed (especially on a steep descent or if you accelerate too hard) the speed fl ashes. Adapt your speed as necessary.
The function will re-engage when your speed has returned below the desired maximum.
Deactivation of the maximum speed
Press button 3.
The information "OFF" will appear on the instrument panel screen.
This action does not cancel the memorised maximum speed, which remains displayed in zone A of the instrument panel.
Temporary override of the maximum speed
You can exceed the memorised maximum speed at any time by pressing the accelerator pedal hard down past the tight spot.
During the time the limit speed is being exceeded, the displayed speed fl ashes.
You have only to release the accelerator pedal to return below the maximum speed, thus keeping the function active.

RADIO SOURCE
Notes on radio reception
Your radio will be subject to certain phenomena that are not encountered by domestic systems.The reception of AM and FM signals may suffer from interference, which is caused by the nature and propagation of the signals and does not refl ect on the quality of your radio installation.In AM, the reception may be affected when passing under power lines or bridges, or when travelling through tunnels.In FM mode, the reception may be affected by the distance from the station transmitter, the refl ecting of signals off obstacles (mountains, hills, tower blocks) and radio blackspots (no coverage from the station transmitter).
Selection of radio source
Press button D to select the source.
Selection of frequencies and memory banks
Press button E successively to go through the memory banks FM1, FM2 and FM3, for the FM waveband, and the memory banks MW/LW, for the AM waveband.
Manual search
Manual seearch is via buttons Jor M.By keeping button J or M pressed, you will be able to scroll through the waveband. Scrolling will stop as soon as you release the button. The radio will remain tuned to the frequency that is displayed.
Tuning sensitivity
Automatic searches can be carried out according to two levels of sensitivity:- To capture the most powerful transmitters, choose the local search mode "LO" (default option).
- To capture the weakest or most distant transmitters, choose the sensitive search mode "DX".
Search for a station is done fi rst in "LO" (local) sensitivity, then in "DX" (distant) sensitivity.To commence a search in sensitivity "DX" (distant) immediately, press twice in succession on one of the buttons K or N.
Automatic search
A short press on one of the buttons K or N will tune into higher or lower radio stations respectively, within the chosen waveband.By keeping button K or N pressed, you will be able to scroll through the waveband. The scrolling will stop at the fi rst station it fi nds once the button is released.You can also do this by means of control 2 at the steering wheel.If the automatic search is unable to tune into a known frequency (perhaps owing to very weak reception), it is possible to search manually to fi nd this station.
Display and selection of a station available in the area in which you are travelling
Briefl y press on button G to bring up a list of stations, this is updated every 10 minutes.You can also update this list at any time by giving a long press on button G.To listen to one of these stations, select by pressing buttons J or Mand validate using button L.

RDS SYTEM
Using the RDS (radio data system) function on FM
The majority of FM radio stations use the RDS system. The radio in your vehicle has this system.The RDS system enables these stations to transmit non-audible data in addition to the broadcasting of their programmes. The data provides access to various functions described in this chapter, such as: display of the station name, intermittent traffi c information fl ashes or automatic scanning of stations. This enables you to continue listening to your chosen radio station, regardless of the different frequencies it uses in the regions through which you are travelling.
Scanning of RDS stations
Your radio keeps the best possible reception by continuously looking for any other frequencies on which the selected radio station is broadcast, automatically choosing the frequency offering the best reception (if the station broadcasts on more than one transmitter or frequency).
Activation/deactivation of the RDS functions
The RDS functions can be accessed via the following two menus:- Main menu (press button O).
- AUDIO menu (press button L).
To activate/deactivate the RDS functions on the display C:
1. Press button O.
2. Select the AUDIO icon using buttons J or M.
3. Confi rm your choice with a press on button L.
4. Select the sub-menu for the FM waveband, via buttons J or M. Confi rm your choice with a press on button L.
5. Select scanning for RDS stations, via buttons J or M.
6. Validate your choice with a press on button L.
7. Using control L, select/deselect to activate/deactivate the function.
8. Validate your choice by selecting "OK" on the display.
To activate/deactivate the RDS functions on the display A:
1. Press button O.
2. Select the AUDIO-CD icon via buttons J or M.
3. Select scanning for RDS stations, via buttons J or M. The system tells you the status (active or inactive) of the function.

5. Then please wait for the display to disappear.
Note:
If the RDS function is active:- The "RDS" on the display will light up provided the station being received uses the RDS system with scanning of frequencies.
- The "RDS" on the display is barred if the station received uses the RDS system without frequency search.
If your RDS function is deactivated, the "RDS" on the display will be absent in all cases.The display will indicate the "NAME" for the stations that use the RDS system and the frequency for stations that do not use it.

Regional search mode
Some stations, when they are organised in networks, broadcast regional programmes at certain times of day, and national programmes at other times.It is possible to search:- Either for a regional station only.
- Or across the whole network in order to fi nd a different programme.
To activate/deactivate this function, proceed as for Scanning of RDS stations.
Note:
