Warning and indicator lamps
When the ignition is switched on
Cer tain warning lamps come on for a few seconds when the ignition is switched on. When the engine is star ted, these warning lamps should go off. If they remain on, before moving off, refer to the information on the warning lamp in question.
Associated warnings
The illumination, fixed or flashing, of cer tain warning lamps may be accompanied by an audible signal and a message in the multifunction screen or in the central colour screen associated with the satellite navigation system.

This information is displayed for a few seconds when the ignition is switched on, at the same time as the ser vice information.
Engine oil level indicator
The vehicle must be on level ground and the engine must have been off for more than 30 minutes for this level check to be accurate.
Oil level correct
Oil level incorrect
This is indicated by the flashing of "OIL" or the display of a specific message in the instrument
panel, coupled with the ser vice warning lamp and accompanied by an audible signal. If the low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid damage to the engine.
Oil level indicator fault
This is indicated by the flashing of "OIL - -" or the display of a specific message in the instrument panel. Consult a CITROËN dealer.
There are 2 marks on the dipstick: - A = max; never exceed this level (risk of damage to the engine), - B = min; top up the level via the oil filler cap, using the correct grade of oil for your engine.
Dipstick
Refer to the "Checks" section to locate the dipstick and the oil filler cap on your engine.

Monitoring

Recommendations for ventilation and air con ditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the passenger compar tment for a few moments.
Put the air flow control at a setting high enough to quickly change the air in the passenger compar tment. The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.
In order for these systems to be fully effective, follow the operation and maintenance guidelines below:  To obtain an even air distribution, take care not to obstruct the exterior air intake grilles located at the base of the windscreen, the nozzles, the vents and the air outlets, as well as the air extractor located in the boot.  Do not cover the sunshine sensor, located on the d ashboard; this is used for regulation of the digital air conditioning system.  Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month to keep it in per fect working order.  Ensure that the passenger compar tment filter is in g ood condition and have the filter elements replaced regularly (refer to the "Checks" secti on). We recommend the use of a combined passenger compa r tment filter. Thanks to its special active additive, it contributes to the purification of the air breathed by the occupants and the cleanliness of the passenger compar t ment (reduction of allergic symptoms, bad odours and greasy deposits).  To ensure correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the Maintenanc e and Warranty Guide.
 If the system does not produce cold air, switch it off and contact a CITROËN dealer or a qualified workshop. When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.

Dual-zone digital air conditioning The air conditioning system operates when the engine is running.
Automatic operation
1. Automatic comfort programme
We recommend the use of one of the three AUTO modes available: they provide optimised regulation of the temperature in the passenger
compar tment according to the comfor t value that you have chosen. These three modes automatically adjust the air flow, according to the desired setting, while also maintaining the desired comfor t value.
 Press the "AUTO" button repeatedly: - a first indicator lamp comes on; the "light" setting mode is selected, - a second indicator lamp comes on; the "medium" setting mode is selected, - a third indicator lamp comes on; the "intense" mode setting is selected.
When the engine is cold, the air flow will reach its optimum level
progressively, taking account of the weather and the desired comfor t level so as to avoid too great a distribution of cold air. On entering the vehicle, if the interior temperature is much colder or warmer than the comfor t value, there is no need to change the value displayed in order to obtain the comfor t required. The system corrects the difference in temperature automatically and as quickly as possible.
This system is designed to operate effectively in all seasons, with the windows closed.

5. Air conditioning On/Off
 Press this button to switch off the air conditioning.
Switching the system off could result in discomfor t (humidity, condensation).  Press this button again to return to automatic operation of the air conditioning. The indicator lamp on the "A /C" button comes on.
6. Air distribution adjustment
 Press one or more buttons to
direct the air flow towards:
- the windscreen and side windows (demisting or defrosting), - the outer and centre air vents, - the footwells. You can combine the three orientations to obtain the desired air distribution.
7. Air fl ow adjustment
 Turn this control to the left to decrease the air flow or to the right to increase the air flow.
8. Air intake/Air recirculation
 Press this button for recirculation
of the interior air. The indicator lamp in the button comes on.
The air flow indicator lamps, between the two fans, come on progressively in relation to the value requested.
9. "REST" function: ventilation with the engine off
Even with the engine is off, you can operate the ventilation for a few minutes.
Air recirculation enables the passenger compar tment to be isolated from exterior odours and smoke.  As soon as possible, press this button again to permit the intake of outside air and prevent the formation of condensation. The indicator lamp in the button goes off.
For example, while you are away from the vehicle, the passengers can still enjoy some air circulation without having the engine running. This function is available after switching on the ignition, as well as after stopping the engine. The period that the function is available depends on the state of charge of the battery. You can activate the "REST" function while the air conditioning control screens are on.

Rear screen demist - defrost
The control button is located on the air conditionin g system control panel.
Switching on
The rear screen demisting/defrosting can only operate when the engine is running.  Press this button to demist /defrost the rear screen and (depending on version) the door mirrors. The indicator lamp associated with the button comes on.
Switching off
The demisting/defrosting switches off automatically to prevent an excessive consumption of current.  It is possible to stop the demisting/defrosting operation before it is switched off automatically by pressing the button again. The indicator lamp associated with the button goes off.
 Switch off the demisting/defrosting of the rear screen and door mirrors as soon as appropriate, as lower current consumption results in reduced fuel consumption.

Heated seats control
With the engine running, the front seats can be heated separately.  Use the adjustment dial, placed on the side of each front seat, to switch on and select the level of heating required: 0: Off. 1: Low. 2: Medium. 3: High.
Additional adjustments
Head restraint height and angle adjustment
 To raise a head restraint, pull it upwards.  To remove the head restraint, press the lug A and pull the head restraint upwards.  To put the head restraint back in place, engage the head restraint stems in the openings keeping them in line with the seat back.  To lower the head restraint, press the lug Aand the head restraint at the same time.  To adjust the angle of the head restraint, tilt its lower par t for wards or rear wards.
The head restraint is fitted with a frame with notches which prevents it from lowering; this is a safety device in case of impact. The adjustment is correct when the upper edge of the head restraint is level with the top of the head. Never drive with the head restraints removed; they must be in place and
adjusted correctly.
