For optimum operation of this system, the settings below are recommended:
recirculation of interior air
This position should only be
temporary.
Used with the air conditioning
switched on and the fan setting
(from 1 to 4), recirculation enables you to
obtain the required ambient air comfort level
with both hot or cold settings.
Recirculation temporarily prevents exterior

The settings range between:
-

increasing the interior ambient air

temperature HI (High) which goes up to
to a maximum setting of 32,
-

cooling the interior ambient air

temperature LO (Low) which goes down
to a setting of 16.
Air distribution
A press illuminates the LED on the buttons
which distribute the air flow towards:
the windscreen and front side
window vents (demisting/
defrosting the windows),
the central and side vents (chest
and face),
the vents in the front and rear
areas (feet).
The combination of buttons permits
improvement of air distribution.
Air flow
Successive presses of this button
increase (+) or reduce (-) the
force of the air flow to the interior.
Intake of exterior air / r ecirculation of interior air
When the LED is on, the air
recirculates inside the passenger
compartment to prevent the entry of exterior
odours and smoke. This position should be
temporary.
When the ambient air comfort level has been
reached, pressing the button switches the
LED off and reopens the exterior air intake.
Pressing the A

button also restores
the intake of exterior air. Returning to this
position permits renewal of the air in the
passenger compartment and demisting.

rapid demisting / defrosting
Pressing this control permits
rapid clearing of the windows.
The LED is on.
The system manages the air conditioning,
the flow and intake of air, the defrosting
of the rear screen and provides optimum
distribution of the air to the windscreen and
front side windows.
If your vehicle is fitted with additional
heating, switch it off to ensure rapid and
effective demisting/defrosting.

c O nd I t IO n I n G
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
easier.
It improves the demisting and defrosting
performance and that of the heated seats, if
fitted to the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The LED
is on if the heating is activated.
When rapid demisting and
defrosting is required, switch off the control.
Automatic additional heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the ambient
temperature and the temperature inside the
vehicle.
It switches off automatically once the
heating system is started manually.

Refer to the "Technical data -
"Dimensions" section for more
information on the length (L1 to L4) and the
height (H1 to H3) of the vehicle. Maximum load on the roof, evenly
distributed: 150 kg, for all versions,
within the vehicle's weight limit (Gross
Vehicle Weight).
For reasons of safety and to avoid damaging
the roof, it is essential to use a carrying
system (roof bars or roof rack) that is
approved for your vehicle.
Roof bars can only be fitted to an H1 or
H2

height van, combi and minibus versions.
On a minibus, check for the presence of roof
air conditioning units. The carrying system must always be
secured to the fitting points provided on the
vehicle's roof: 6, 8 or 10, depending on the
wheelbase of the vehicle.
Observe the instructions for fitting and use
provided with the carrying system.
On all H3 height versions, the roof
cannot be fitted with a carrying system.
Observe in full the legal requirements
related to carrying outsized loads.

ACCESSORIES

131
The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery.These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.
cHEcKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the diesel
filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger
compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.
