Engine oil temperature gauge
Under normal operating condi-tions, the bars should be within section 1.
In severe operating conditions, the bars may extend into section 2.
In this event, slow down, and if nec-essary, stop the engine and check the levels (see chapter - Mainte-nance - “Levels”).
Fuel gauge
On horizontal ground, the lighting of the fuel low warning lamp warns you that you are using the reserve tank.
A message alert is displayed on the instrument panel.
Coolant temperature indicator
Under normal operating condi-tions, the bars should be within section 1.
In severe operating conditions, the bars may extend into section 2, the engine coolant temperature warn-ing lamp A and the STOP warning lamp will light up, stop immedi-ately.Switch off the ignition. The cooling fan may continue to operate for a certain time. Allow the engine to cool down while tak-ing the precautions indicated in chapter - Maintenace - “Levels”.
Contact a CITROËN dealer.
If the SERVICE warning lamp lights up, check the levels (see chapter - Maintenance - “Levels”).

You are advised to use the auto-matic air conditioning regulation. This automatically regulates the following functions for maximum comfort : air fl ow, passenger com-partment temperature, and air dis-tribution, 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 sun-light sensor A.
Provided you retain automatic mode (by pressing button “AUTO”) and all the air vents are open, you will maintain an optimum comfort level, also removing humidity and misting, whatever the ambient cli-matic conditions.
The temperature inside the cabin cannot be lower than the tempera-ture outside if the air conditioning is not operating.
To be effective, the air conditioning should only be used with the win-dows closed. If after a lengthy stop in bright sunlight the interior tem-perature is excessive, air the pas-senger compartment by opening the windows for a few moments, then close them again.
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 not 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 t-ted 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 accord-ing to the vehicle maintenance sched-ule. See “Maintenance Guide”.
To ensure the correct operation of the air conditioning system, it is essential to operate the air condi-tioning at least once a month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.
In certain extreme operating con-ditions (e.g. carrying a full load up a steep gradient in high tempera-tures), 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 bottom of the wind-screen, is clean and free of dead leaves, snow, etc.
If washing the vehicle with a high pressure jet, avoid targeting the air inlet zone.

Selection and activation of a programmed time
Press button 3 until the programme number corresponding to the required programmed time is dis-played. The chosen pre-selected time is automatically activated after 10 seconds if no other but-tons have been pressed.
To confi rm that the mode is acti-vated, symbols 4 and 8 fl ash until the heating starts up.
When the heating starts up, the warning lamp 9 lights up on the dashboard and the programmer screen.

Adjusting the operating durationPress button 3 and hold it down. Press button 2 or 7 at the same time. Release button 3. The time and symbol 6 are displayed.Press again on button 3 and hold it down. Press button 2 or 7 at the same time. Release button 3. The operating duration and symbol 8 is displayed.Adjust the operating duration with button 2 or 7.
Note : The operating duration is memorised when the time indicated disappears or by pressing button 3.
Adjusting the remaining operating duration
When heating mode is activated, the remaining operating time can be modifi ed within the range of 10 to 60 minutes using buttons 2 or 7.
Note :The pre-selected start-up time can be modifi ed or cancelled by following the instructions previ-ously given above.
In the event of a battery discon-nection, the programmer must be re-set (hours, minutes etc.)


Always switch off the additional heating when filling up with fuel, to prevent any risk of fi re or explosion.
To avoid any risk of intoxica-tion or asphyxiation, the addi-tional heating must not be used, even for short periods, in an enclosed area such as a garage or workshop not equipped with a system for the extraction of exhaust gases.
Do not park the vehicle over infl ammable materials (e.g. dry grass, dead leaves or paper) as this could present a fi re risk.
The programmable heating sys-tem is supplied by the vehicle’s fuel tank. Before use, ensure that the remaining fuel level is suffi cient. If you are using the reserve fuel tank, we strongly advise you not to use the pro-grammable heating system.
