Recommendations for ventilation and air co nditioning
If after an extended stop in sunshine, the interior temperature is very high, first ventilate the cabin 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.

When you move the lever in the gate to select a position, the corresponding indicator is displayed on the instrument panel. P. Park R. Reverse N. Neutral D. Drive (Automatic driving) S.

Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated. If a level drops significantly, have the corresponding system checked by a CITROËN dealer.
Oil level
Engine oil change
Refer to the Maintenance and Warranty Guide for details of the inter val for this operation.
In order to maintain the reliability of the engine and emission control system, the use of additives in the engine oil is prohibited.
Oil grade
The oil must be suitable for your engine and conform to the manufacturer's recommendations.
Brake fluid level
Changing the fl uid
Refer to the Maintenance and Warranty Guide for details of the inter val for this operation.
Fluid specifi cation
The brake fluid must conform to the manufacturer's recommendations and meet the DOT4 standard.
The brake fluid level should be close to the "MA X" mark. If it is not, check the brake pad wear.
The reading will only be correct if the vehicle is on level ground and the engine has been off for more than 15 minutes. The check is carried out either when the ignition is switched on using the oil level indicator on the instrument panel, or using the dipstick.

Checks
Battery
Air filter and passenger compartment filter
Oil filter
Particle emission filter
(Diesel)
It is imperative that the maintenance of the par ticle emission filter is carried out by a CITROËN dealer.
Following prolonged operation of the vehicle at very low speed or at idle, you may, in exceptional circumstances, notice the emission of water vapour at
the exhaust on acceleration. This does not affect the behaviour of the vehicle or the environment.
Unless other wise indicated, check these components in accordance with the Maintenance and Waranty Guide a nd according to your engine. Other wise, have them checked by a CITROËN dealer.
The battery does not require any maintenance. However, check that the terminals are clean and correctly tightened, particularly in summer and winter. When carrying out work on the battery, refer to the "Practical information" section for details of the precautions to be taken before disconnecting the battery and following its reconnection.
Refer to the Maintenance and Warranty Guide for details of the replacement inter vals for these components. Depending on the environment (e.g. dusty atmosphere) and the use of the vehicle (e.g. city driving), replace them twice as often if necessar y (refer to the "Engines" paragraph). A clogged passenger compar tment filter may have an adverse effect on the per formance of the air conditioning system and generate undesirable odours.
Replace the oil filter each time the engine oil is changed. Refer to the Maintenance and Warranty Guide for details of the replacement interval for this component.

Manual gearbox
Automatic gearbox
Brake pads
Brake wear depends on the style of driving, par ticularly in the case of vehicles used in town, over shor t distances. It may be necessary to have the condition of the brakes checked, even between vehicle ser vices. Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
The gearbox does not require any maintenance (no oil change). Refer to the Warranty and Maintenance Record for the details of the level checking inter val for this component.
Brake disc wear
Parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. This system must be checked by a CITROËN dealer.
Only use products recommended by CITROËN or products of equivalent
quality and specifications. In order to optimise the operation of units as impor tant as the braking
system, CITROËN selects and offers very specific products. To avoid damaging the electrical units, the use of a high pressure washer
in the engine compar tment is strictly prohibited .
The gearbox does not require any maintenance (no oil change).
Refer to the Warranty and Maintenance Record for details of the level checking interval for this component.
For information relating to checking the brake disc wear, contact a
CITROËN dealer.
