compartment are at a comfortable
temperature, you can switch off the
function; reducing electric current
consumption also reduces fuel
consumption.Prolonged use at the highest setting
is not recommended for those with
sensitive skin.
There is a risk of burns for those that
do not have normal perception of heat
(illness, taking medicines,
...).

Recommendations for ventilation and air conditioning
If after an extended stop in sunshine,
the interior temperature is very
high, first ventilate the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F

T

o 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.
F

D

o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

O

perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.
F

E

nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e recommend the use of a combined passenger compartment 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 compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T

o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.
F

I

f the system does not produce cold air, switch it off and contact a CITROËN dealer or
a qualified workshop.
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.
Stop & Start
The heating and air conditioning systems only work when the engine is running.
To maintain a comfortable temperature in the passenger compartment, you can temporarily
deactivate the Stop & Start system.
For more information on Stop & Star t
, refer to the corresponding section.

Manual air conditioning
The air conditioning system operates only with the engine running.
1. Temperature adjustment
F Turn the dial to select a position between blue (cold)
and red (hot) so as to adjust
the temperature to your
requirements.
2. Air flow adjustment
This dial is used to increase or
decrease the speed of the air
booster fan.
3. Air distribution adjustment
This dial is used to arrange the distribution of
air in the passenger compartment by combining
several air outlets.
F

I

f you place the air flow control
in position 0 , the system is
deactivated. However, a slight flow
of air, due to the movement of the
vehicle, can still be felt.
F

T

urn the dial from position 1 to position 5 to
obtain a comfortable air flow. Windscreen and side windows.

Dual-zone digital air conditioningThe air conditioning system operates when the engine is running.
Automatic operation
1. Automatic comfort programme
F Press the "AUTO" button
repeatedly:
-

a f
irst indicator lamp comes
on; the "light" setting mode is
selected,
-

a s
econd indicator lamp
comes on; the "medium"
setting mode is selected,
-

a t
hird indicator lamp comes
on; the "intense" mode
setting is selected. When the engine is cold, the air
flow will reach its optimum level
progressively, taking account of the
weather and the desired comfort level
so as to avoid too great a distribution
of cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value, there is no
need to change the value displayed in
order to obtain the comfort required.
The system corrects the difference
in temperature automatically and as
quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed. We recommend the use of one of the three
AUTO modes available: they provide optimised
regulation of the temperature in the

passenger
compartment according to the comfort value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while
also maintaining the desired comfort value.

-

t
he windscreen and side
windows (demisting or
def r o st ing),
-

t
he outer and centre air
vents,

You can combine the three orientations to
obtain the desired air distribution.
7. Air flow adjustment
F Turn this control to the left to decrease the air flow or to the
right to increase the air flow.
8. Air intake / Air recirculation
F Press this button for recirculation
of the interior air. The indicator
lamp in the button comes on.
The air flow indicator lamps, between the two
fans, come on progressively in relation to the
value requested.
9. "REST" function: ventilation with the engine off
Even with the engine is off, you can
operate the ventilation for a few
minutes.
Air recirculation enables the passenger compartment
to be isolated from exterior odours and smoke.
For example, while you are away from the
vehicle, the passengers can still enjoy some air
circulation without having the engine running.
This function is available after switching on the
ignition, as well as after stopping the engine.
The period that the function is available
depends on the state of charge of the battery.
You can activate the "REST" function while the
air conditioning control screens are on.
Avoid prolonged operation in interior air
recirculation mode (risk of misting and
deterioration of air quality).
