Maintenance intervals
If you use your vehicle in par-ticularly diffi cult conditions, it is essential to have recourse to the service schedule for “special con-ditions” comprising shorter inter-vals between services. See “Main-tenance Guide”.

Your CITROËN technician resets the indicator to zero after each service. However, if you do your own servicing, the procedure for resetting to zero is as follows:1. Switch off the ignition.2. Press on button A and keep it pressed.3. Switch on the ignition.4. Keep button A pressed down until the screen indicates “=0” and the maintenance symbol disappears.
Note: If the maximum time between two oil changes is reached before the mileage has been covered, the mainte-nance spanner lights up and the instrument panel indicates “0instrument panel indicates “instrument panel indicates “”.
MILEAGE RECORDER
Display
When the driver's door is opened or the vehicle is unlocked with the remote control, for around 30 sec-onds there is display of the mile-age recorders and sometimes the maintenance spanner.
Trip mileage recorder reset
This can operate when the ignition is switched on.
With a long press on the zero reset button A, the trip mileage dis-played resets to zero.

MAINTENANCE INDICATOR
It informs you when the next routine service is due in accordance with the vehicle servicing schedule in the Main-tenance Guide. This information is dependent on two parameters: the mileage covered, and the time elapsed since the last visit.
Operation
From switching on the ignition and for a few seconds, the span-ner symbolising maintenance operations lights up ; the instru-ment panel tells you the distance remaining to the next service.
Example: there remain up to the next service:
A few seconds after this, the engine oil level indicator is displayed, then the total mileage recorder resumes its normal role. The instrument panel gives the total and trip mile-ages.
Operation if the distance to the next service is less than 1 000 km (600 miles)
Each time you switch on the igni-tion and for 5 seconds, the span-ner and the distance fl ash.
Example: There remain up to the next service: 500 km (500 miles). On switching on the ignition and for 5 seconds, the instrument panel indicates:
A few seconds after this, the engine oil level indicator is displayed, then the total mileage recorder resumes its normal role and the mainte-nance symbol remains lit up.
This is a warning to you that a service must be carried out at the earliest opportunity.
The instrument panel gives the total and trip mileages.
Operation if the service interval has been passed
Each time you switch on the igni-tion, the maintenance symbol and the distance covered (preceded by a minus) beyond the recommended interval fl ash.
Example: You have passed the serv-ice interval by 300 km (300 miles).
The routine service on your vehicle needs to be carried as soon as pos-sible.
A few seconds after switching on the ignition, the total mile-age recorder resumes its normal role and the maintenance symbol remains lit up.

AIR CONDITIONING
This system automatically adjusts the temperature, the fl ow of air and the distribution of air inside the cabin, depending on your desired comfort level.
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 keep the air conditioning compressor well sealed, it is essential to operate the air conditioning at least once in every month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
Sensors
The automatic regulation of the air conditioning inside the cabin uses a number of sensors (sunlight, ambient temperature, inside temperature, etc.) relieving you of the need to make your own adjustments within a normal temperature range.
The humidity sensor is there to prevent misting inside the vehicle.
Be careful not to obstruct the sensors A and C.
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.
The air vents to the face have thumbwheels so that you can adjust the fl ow of air, and grilles to orient the direc-tion.
There are air vents on the fl oor underneath the front seats and on the rear control panel, for enhanced heat-ing of the rear seat positions.
Do not obstruct the air outlets located in the boot area.
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”.
Additional heating
Vehicles with an HDi engine may be provided with auto-matic additional heating for enhanced comfort.
It is normal to notice slight odours or smoke emissions, especially when the vehicle is idling or stationary.
