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 dashboard; 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 compartment filter is in good condition and have the filter elements replaced regularly (refer to the "Checks" section). We recommend the use of a combined passenger compartment 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 compartment (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 maintenance and warranty guide.  If the system does not produce cold air, switch it off and contact a CITROËN dealer or a qualified workshop. You can switch off the air conditioning (AC button) and stay in Automatic mode in order to limit fuel consumption. If misting appears while in this mode, you can switch the air conditioning back on temporarily to improve the situation. 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.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the passenger compartment for a few moments. Put the air flow control at a setting high enough to quickly change the air in the passenger compartment. The air conditioning system does not contain chlorine and does not present any danger to the ozone layer.
The condensation created by the air conditioning results in a discharge of water under the vehicle which is per fectly normal.
If you want to prioritise heating, start and leave the engine running by pressing ECO OFF.
Depending on version and country of sale, contains fluorinated greenhouse gas R134A (gas capacity 0.450 kg +/- 0.025 kg, GWP index 1 430, 0.644 t equivalent CO2).

Driving recommendations
Observe the driving regulations and remain vigilant whatever the traffic conditions. Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at any time to any eventuality. As a safety precaution, the driver must only carry out actions requiring sustained attention when the vehicle is stationary. On a long journey, a break every two hours is strongly recommended. In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from other vehicles.
Driving on flooded roads
We strongly advise against driving on flooded roads, as this could cause serious damage to the engine or gearbox, as well as to the electrical systems of your vehicle.
- check that the depth of water does not exceed 15 cm, taking account of waves that might be generated by other users, - deactivate the Stop & Start system, - drive as slowly as possible without stalling. In all cases, do not exceed 6 mph (10 km/h), - do not stop and do not switch off the engine.
Important!
Never drive with the parking brake applied - Risk of overheating and damage to the braking system! Risk of fire! As the exhaust system of your vehicle is very hot, even several minutes after switching off the engine, never park or leave the engine running where the vehicle is on an inflammable sur face: (grass, dead leaves, paper, etc.): risk of fire.
Never leave a vehicle unsupervised with the engine running. If you have to leave your vehicle with the engine
running, apply the parking brake and put the gearbox into neutral or position N or P , depending on the type P , depending on the type Pof gearbox.
If you are obliged to drive through water:
On leaving the flooded road, as soon as circumstances allow, make several light brake applications to dry the brake discs and pads. If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.
