Heating and Ventilation


Air intake

The air circulating in the passenger compar tment
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.

System which creates and maintains good
conditions of comfor t and visibility in the
vehicle's passenger compar tment.
The heating and ventilation can be used as
soon as the "Ready" lamp is on.

Controls

The incoming air follows various routes
depending on the controls selected.
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
select the air vents used in the passenger
compartment.
The air flow control enables you to increase or
reduce the speed of the ventilation fan.
These controls are grouped together on control
panel A
on the centre console.

In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:


)
If the interior temperature remains very high after the vehicle has been parked in
the sun for a considerable time, first ventilate the passenger compartment for a few
minutes by opening the windows.
Place the air flow control at a sufficient level to provide an adequate renewal of air in
the passenger compar tment.

)
Condensation created by the air conditioning results in a discharge of water under
the vehicle when stationary, which is per fectly normal.

)
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.

)
Use in preference the intake of exterior air as prolonged use of the air recirculation may
cause misting of the windows and side windows.

)
Operate the air conditioning system for 5 to 10 minutes, once or twice a month to keep it
in good working order.

)
Ensure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to "Checks").

)
To ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly.

)
If the system does not produce cold air, do not use it and contact a CITROËN dealer or
a qualified workshop.











Recommendations for ventilation and air conditioning


The heating and air conditioning use
energy from the main battery. Their use
increases electrical consumption and
reduces the range of the vehicle.
Remember to switch off the heating
or air conditioning as soon as it is no
longer needed.

Checks
Unless other wise indicated, check these components in accordance with the ser vicing booklet.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.


Passenger compartment filter

Refer to the servicing booklet for
details of the replacement inter vals
for this filter.
Depending on the environment
(e.g. dusty atmosphere) and the use of the
vehicle (e.g. city driving), replace it twice as
often if necessar y
.
A dir ty passenger compar tment filter may have
an adverse effect on the per formance of the air
conditioning system and generate undesirable
odours.
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 services.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.



















Brake pads

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.


Parking brake

If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.

Brake disc/drum wear

For information on checking the
brake disc or drum wear, contact
a CITROËN dealer or a qualified
workshop.
