Vent ilat ion
The incoming air follows various routesdepending on the controls selected by thedriver:
- direct arrival in the passenger compartment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).
The temperature control enables you to obtain
the level of comfor t required by mixing the air of
the various circuits.
The air distribution control enables you to
di
ffuse the air in the passenger compar tment combining several air vents.
The air flow control enables you to increase or reduce the speed of the ventilation fan.
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the outside
via the grille located at the base of the windscreen or from the inside in air recirculation mode.


Control panel

The controls of this system are grouped
together on control panel Aon the centre console. Depending on the model, the functionsoffered are:


- the level of comfor t required,

- air flow
,

- air distribution

Checks

Checking levels
Brake fluid level Oil level
The check is carried out either when
the ignition is switched on using theoil level indicator on the instrument panel, or using the dipstick. Th
e brake fluid level should be close
to the "MA X" mark. If it is not, check
the brake pad wear.

Changing the fl uid

Refer to the ser vicing booklet for details of the
interval for this operation.
Engine oil change
Refer to the servicing booklet for details of theinterval 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 specifi cation
The oil must be the correct grade for your
engine and conform to the manufacturer'srecommendations.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT3 or DOT4 standard.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.
Check all of these levels regularly, in line with the ser vicing booklet and the requirements of the warranty. Top them up if necessary, unless other wise indicated.


Take care when working under the bonnet, as certain areas of the engine may be extremely
hot (risk of burns) and the cooling fan could star t at any time (even with the ignition off).

It is normal to top up the oil levelbetween two ser vices (or oil changes).CITROËN recommends that you check the level, and top up if necessary, every3 000 miles (5 000 kms). After topping up the oil, the check when switching on the ignition with the oil level indicator in the instrument panel is not valid during the 30 minutes after topping up. It will onl
y be correct if the vehicle is on level ground and the engine has been off for more
than 30 minutes.

Coolant level

The coolant level should be close
to the "MA X" mark but should never exceed it.

Fluid specifi cation

For optimum cleaning and to avoid freezing,
this fluid must not be topped up or replaced
with plain water.

Fluid specifi cation
The coolant must conform to themanufacturer's recommendations.
Changing the coolant
The coolant does not have to be changed.
Screenwash fluid level
When the engine is warm, the temperature of
the coolant is regulated by the fan.
Top up the level when necessary.
The cooling fan may star t after switching
off the engine: take care with ar ticles andclothing that might become caught by thefan blades.
In addition, as the cooling system is pressurised,
wait at least one hour after switching off theengine before carrying out any work.
To avoid any risk of scalding, unscrew the cap
by two turns to allow the pressure to drop.
When the pressure has dropped, remove the
cap and top up the level.
Diesel additive level
(Diesel engine with particle
emission filter)
