This driving assistance device warns you when you unwittingly cross a lane marking (either a continuous or a dotted line on the road surface). It is designed for use on motorways and dual carriageways, operatin g only above speeds of approx. 80 km/h (50 mph).
Activation/Deactivation
A press on button A activates the function, the warning lamp on the button lights up.
A second press on button A deactivates the function, the warning lamp on the button goes out.
When you start the engine, the mode (activated/deactivated) selected when you stopped the engine is retained.
Operation
Above a speed of around 80 km/h (50 mph), if you cross a lane markin g, you are alerted to this by a vibration within the cushion of your seat:On the right hand side if you cross a lane marking to the right.On the left hand side if you cross a lane marking to the left.
The system does not alert you if one of your direction indicato rs is operating and for approx. 20 seconds after the direction indicator has stopped.
Remarks:
This system is designed to identify traffi c lane markings.
In certain cases it may trigger an alert that is unnecessary, for e xample if the vehicle passes over a directional arrow or some unusual road marking.
The system may be affected temporarily by conditions external to th e vehicle:Detection of lane markings made diffi cult by:
Markings being worn.Insuffi cient contrast with the general road surface.Sensors being negated by:
Driving in snow or heavy rain.Driving on roads that are covered with mud or water puddles.

You are advised to use the automatic air conditioning regulation. This automatically regulates the following functions for maximum comfort : air fl ow, passenger compartment temperature, and air distribution, using different sensors (external temperature, sunlight). This avoids the need to alter any of the settings, with the exception of the temperature displayed.
Take care not to obstruct the sunlight sensor A.
Provided you retain automatic mode (by pressing button “AUTO”) and all the air vents are open, you will main-tain an optimum comfort level, also removing humidity and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than the temperature outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the windows closed. If after a lengthy stop in bright sunlight the interior temperature is excessive, air the passenger compartment by opening the windows for a few moments, then close them again.
To ensure the correct operation of the air conditioning system, it is essential to operate the air conditioning at least once a month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
In certain extreme operating conditions (e.g. carrying a full load up a steep gradient in high temperatures), the switching off of the air conditioning allows more power to be transferred to the engine, thereby increasing the towing capacity.
Air inlet
Check that the exterior grille for the air inlet, at the bot-tom of the windscreen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper distribution of air within the cabin, both at the front and at the rear.
To obtain an even distribution of air, ensure that you do obstruct the external air inlet grille located at the base of the windscreen, the air vents, the air outlets on the fl oor underneath the front seats, and the air extractor located behind the fl aps in the boot.
The front and rear air vents are fi tted with control knobs which allow you to control and direct the air fl ow. It is recommended to keep all the air vents open.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This fi lter has to be changed according to the vehicle maintenance schedule. See “Maintenance Guide”.

7. Rear demisting - deicing
Press button 7, with the engine running, to start a rapid deicing or demisting of the rear screen and rear view mirrors. The warning lamp comes on.
This mode automatically stops depending on the out-side temperature. It can be interrupted by a further press on button 7 or by stopping the engine.
In the latter case, demisting will resume when the engine is switched on again.Note: The heated rear screen operates independently of the automatic air conditioning.
This button activates the recirculation of air in the pas-senger compartment.
Press button 8 to switch off the entry of air from outside. The warning lamp comes on.
Whilst retaining the other settings, this position allows the driver at any moment to exclude unpleasant smells or smoke/emissions coming from outside.
This mode should be cancelled as soon as possible to allow the redistribution of air in the passenger compartment.
8. Air recirculation – Entry of air from outside
Remarks:When starting from cold, in order to prevent unwanted cold air, the air fl ow will increase only gradually to its optimum level.
If you enter the vehicle after a fairly prolonged stop and the temperature inside the vehicle is far from comfortable, it serves no purpose to modify the tem-perature that is displayed as an attempt to go imme-diately to the desired comfort level. The system automatically uses all of its power to compensate the temperature gap as quickly as possible.Water arising from the condensation in the air con-ditioning drains out through a hole provided for this purpose ; a pool of water may thus form underneath the vehicle when stationary.
Whatever the time of year, even in cool weather the air conditioning is useful in removing humidity and misting. Avoid driving for too long with air condition-ing deactivated.

8. Front demisting - deicing
In some cases, “AUTO” mode may not be suffi cient to demist or defrost the windows (e.g. humidity, several passengers, frost).
Press button 8 for rapid clear windows. The warning lamp comes on. This system controls air conditioning, temperature and air fl ow/entry. It distributes ventilation towards the windscreen and the front windows.
You can manually exit “Demisting” mode. This mode should be cancelled as soon as possible to allow the redistribution of air in the passenger compartment.
A press on either of the buttons 1a or 1b allows you to return to “AUTO” mode.

QUESTIONANSWERSOLUTION
Traffi c Announcements (TA) is displayed. I do not receive any traffi c informa-tion or public announce-ments.
The particular radio station is not in the regional traffi c information network.Change to a radio station that does broadcast traffi c information.
The reception quality of the radio station being lis-tened to gradually deterio-rates.
The vehicle is too distant from the transmit-ter, or no transmitter is present in the geo-graphical area you are passing through.
Activate the RDS function to allow the system to check whether a more pow-erful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tun-nels, underground 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.
Cutting of sound for 1 to 2 seconds in radio mode.
The RDS system during this brief sound cut-off is searching for a better frequency that might offer improved reception of the station.
Deactivate the RDS function if the phe-nomenon occurs 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 work-ing time for the radio depends on the battery charge. The interruption is normal: the radio goes into economy mode, cutting off 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.
