CORRECT USE OF THE AIR CONDITIONING
In order to be effective, the air conditioning
should only be used with the windows
closed. However, if the interior temperature
remains high after a prolonged period
parked in the sun, first ventilate the
passenger compartment for a few minutes. For even air distribution, ensure that the
exterior air intake grille located at the base
of the windscreen, the side and central
vents, the air outlets on the floor and the air
extractor at the rear are not obstructed.
The air conditioning is useful in all seasons
as it eliminates condensation and air
humidity. Operate the air conditioning system for
5 to 10 minutes, once or twice a month,
to keep it in good working order.
Have the filter elements (air filter and
passenger compartment filter) replaced
regularly. If you drive in a dusty environment,
have them replaced twice as often.
It is normal that the condensation created by
the air conditioning system results in a flow
of water which may form a puddle under the
vehicle when parked.
If the system does not produce cold air,
do not use it and have it checked by a
CITROËN dealer or a qualified workshop.
"Leave them open"
For optimum distribution and diffusion of hot
or cool air in the passenger compartment,
there are: 4 adjustable central vents, of
which 2 can be directed sideways (right
or left) towards the top of the body and
4 side vents which can be directed towards
the passengers. The air vents directed
towards the floor of the vehicle complete the
equipment.

diffusion directed forwards.
REAR HEATING AND/OR AIR CONDITIONING
If your vehicle is fitted with an
additional air conditioning unit,
located in the rear of the vehicle:
the distribution duct located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from the
front air conditioning unit, is distributed at
the feet of the rear passengers of rows 2
and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
Additional heating
This is passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or programmable additional heating
This is an additional, programmable and
separate system which heats the Diesel
engine hot coolant loop to make starting

Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator lamp is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use only genuine replacement parts.
Recalling one of the pre-selected start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the screen remain on.
Switching off the heating
Press this button.
The heating cycle indicator lamp
and the screen are switched off.
Two different types of equipment
The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, demisting and defrosting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.
