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.

the interior air. The indicator
lamp comes on to confirm this.
This function allows hot or cold air to be
delivered selectively and more quickly.
5. Air conditioning On/Off
The air conditioning is designed to operate
effectively in all seasons, with the windows
closed.
It enables you to:
-

l
ower the temperature, in summer,
-

i
ncrease the effectiveness of the demisting
in winter, above 3 °C.
Switching on
The air conditioning does not operate
when the air flow adjustment control 2
is in position " 0".
To obtain cooled air more quickly, you
can use recirculation of interior air for
a few moments. Then return to fresh
air intake.
The recirculation of interior air isolates the
passenger compartment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the the air quality
and the formation of mist.

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.

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.
