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.
Recommendations for ventilation and air conditioning
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 condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
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.
Contains fluorinated greenhouse gas R134A.
From 1st October 2016, depending on version and country of sale, contains fluorinated
greenhouse gas R134A (gas capacity 0.525 kg +/- 0.025 kg, GWP index 1 430, 0.751 t
equivalent CO

contain chlorine and does not present
any danger to the ozone layer.

Digital air conditioning (dual-zone)
The air conditioning system operates with the engine running.
Dual-zone: this is the independent regulation of the temperature and air distribution on the driver's
side and the front passenger's side.
The driver and front passenger can each adjust the temperature and the air distribution to suit their
requirements.
The symbols and messages associated with the digital air conditioning controls appear in the
display screen. This is the normal system
operating mode. In accordance
with the level of comfort chosen,
pressing this control, confirmed
by illumination of indicator
lamp
A, permits automatic and
simultaneous control of all of the
following functions:1a-1b. Automatic operation

5. Air flow adjustment
Reducing the air flow to minimum switches
the air conditioning system OFF.
To prevent condensation and deterioration
of the quality of the air in the passenger
compartment, ensure that an adequate flow of
air is maintained.
6. Air conditioning
The air conditioning will only
operate when the engine is running.
The air blower control (air flow
adjustment) must be active in order
to obtain air conditioning.
7. Recirculation of interior air
F Press control 7 once to activate recycling of the
interior air.
This function permits recirculation
of the air and isolation of the
passenger compartment from
exterior fumes and odours.
F

P

ress button 7 again
to activate automatic
recirculation with pollution
detection. F

P
ress control 7 a third time
to return to the standard
automatic mode (without
pollution detection).
Using a pollution sensor, the system
automatically activates recirculation of the
interior air once it detects a certain level of
pollutants in the interior air.
When the air quality returns to a satisfactory
level, the recirculation of interior air is
automatically deactivated.
F
P
ress the control:
-
t
o increase the air flow,
-

t

o reduce the air flow.
The air flow level is indicated by the
progressive illumination of the fan
blade indicator lamps.
Avoid prolonged use of air
recirculation
- Risk of misting and
deterioration of air quality!
You can store the settings of the air
conditioning system.
For more information on the Front
seats (and in particular storing driving
positions), refer to the corresponding
section.
F

P

ress control 6 . The indicator lamp comes
on.
In order to be effective, the air conditioning
must be used with the windows closed. Recirculation of the interior air is automatically
activated when engaging reverse or if the
screenwash is used.
The system is inactive when the ambient
temperature is below +5 °C to avoid the risk of
formation of mist on the windscreen and side
windows. This system is not designed to detect
unpleasant odours.
The system is inactive when the exterior
temperature is below +5 °C to avoid the risk of
formation of mist on the windscreen and side
windows.

9. Front demisting / defrosting
In certain cases, the "AUTO"
mode may not be sufficient to
demist or defrost the windows
(humidity, several passengers,
i c e).
8. Rear demisting / defrosting
The heated rear screen operates
independently of the air
conditioning system.
F

P

ress control 8 , with the engine running, to
demist the rear screen and the mirrors. The
indicator lamp comes on.
Demisting is switched off automatically to
avoid excessive consumption of current and
depending on the exterior temperature.
It may be stopped by pressing control 8 again
or when the engine is switched off.
In this latter case, the demisting resumes if the
engine is switched on again within one minute. F

P
ress control 9 to clear the windows
quickly. The indicator lamp comes on.
This system controls the temperature, air flow
and intake and distributes the ventilation to the
windscreen and front side windows.
Resuming manual control exits from the
"Demisting" mode. It must be cancelled as
soon as possible to permit renewal of the air in
the passenger compartment and demisting.
Pressing one of the controls 1a or 1b returns
the system to the "AUTO" mode.
With Stop & Start, when demisting has
been activated, the STOP mode is not
available. When starting with the engine cold,
air flow will reach its optimum level
gradually to prevent an excessive
distribution of cold air.
When entering the vehicle after it has
been parked for a fairly long period, if
the interior temperature is very different
from your comfort setting there is
no need to change the temperature
displayed in order to quickly reach the
level of comfort required. The system
automatically uses its maximum
per formance to correct the difference in
temperature as quickly as possible.
The water resulting from the air
conditioning condensation is
discharged via an opening provided
for this purpose; therefore, a puddle of
water may form underneath the vehicle
when stationary.
In all seasons, if the weather is cool,
the air conditioning is useful as it
removes the humidity from the air
and the condensation. Avoid driving
for prolonged periods with the air
conditioning switched off.
Switch off the rear screen and
exterior mirrors demisting when you
consider this necessary, as low current
consumption reduces fuel consumption.
