Recommendations for ventilation and air co nditioning
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 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 guarantee correct operation of the air conditioning system, you are also advised to have it checked regularly as recommended in the Maint enance and Warranty Guide.
 If the system does not produce cold air, deactivate it and contact a CITROËN dealer. 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.

Fuel tank Fuel tank capacity: approximately 50 litres (petrol) or 48 litres (Diesel).
Low fuel level
Filling
A label affixed to the inside of the flap reminds you of the type of fuel to be used depending on your engine. Additions of fuel must be of at least 5 litres, in order to be taken into account by the fuel gauge.
The key cannot be removed from the lock until the cap is refitted. Opening the filler cap may create a noise a caused by an inrush of air. This vacuum is entirely normal, resulting from the sealing of the fuel system.
To fill the tank in complete safety:  the engine must be switched off, open the fuel filler flap,  inser t the key in the cap, then turn it to the left,
 remove the cap and hook it onto the clip located on the inside of the flap,  fill the tank, but do not continue after the 3rd cut- off of the pump ; this could cause malfunctions.
When you have filled the tank:  put the cap back in place,  turn the key to the right, then remove it from the cap,  close the flap.
When the fuel tank minimum level is reached this warning lamp comes
on on the instrument panel. When it first comes on there remains approximately 5 litres of fuel in the tank. You must refuel as soon as possible to avoid running out of fuel. If you run out of fuel (Diesel), refer also to the "Checks" section.

Deactivation
In exceptional conditions (star ting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can
move freely and regain grip.  Press the "ESP OFF" button, located on the left below the steering wheel.
If this warning lamp comes on in the instrument panel and the indicator lamp on the button comes on, this indicates that the ASR and ESP systems are deactivated.
Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h) (except 1.6 litreTHP 150 petrol engine).
 Press the "ESP OFF" button again to reactivate them manually.
Operating fault
The ESP/ASR systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed. The correct functioning of these systems depends on obser vation of the manufacturer's recommendations regarding the wheels (tyres and rims), the braking components, the electronic components and the CITROËN assembly and operation procedures. After an impact, have these systems checked by a CITROËN dealer.
If this warning lamp comes on, accompanied by an audible signal and a message on the multifunction screen, this
indicates a malfunction of these systems. Have the systems checked by a CITROËN dealer.
