In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F

To 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

Do not cover the sunshine sensor, located on the dashboard; this is used for regulation

of the air conditioning system.

F

Operate the air conditioning system for at least 5 to 10 minutes, once or twice a month

to keep it in perfect working order.

F

Ensure that the passenger compartment filter is in good condition and have the filter

elements replaced regularly.

We 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

To 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

If the system does not produce cold air, switch it off and contact a CITROËN dealer or a

qualified workshop.

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.

The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
perfectly normal.

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.

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 & Start,
refer to the corresponding section.

the cursor from blue (cold) to red
(hot) to adjust the temperature to
your wishes.

Air flow adjustment

F Press one of these buttons to

increase or decrease the speed

Air distribution adjustment

The recirculation of interior air prevents exterior
odours and smoke entering the passenger
compartment.
This function also allows the air in the
passenger compartment to be heated or cooled
more quickly.

Windscreen.

Centre and side vents.

Footwells.

The air distribution can be varied by using
more than one button: illumination of the
button indicates that air is distributed in that
direction; no illumination indicates that air is not
distributed in that direction.
Pressing all three buttons gives an even
distribution in the passenger compartment.

Air intake / Air recirculation

F Press this button to select the

exterior air intake mode to the
passenger compartment.

Avoid driving for too long without
ventilation (risk of misting and
deterioration of air quality).

The heating system works only when the
engine is running.
Press the button for the Air conditioning
menu to display the page for the system
controls.

The symbol for air flow (a fan) fills progressively
according to the air flow setting made.
By reducing the air flow to the minimum, you
are stopping ventilation of the passenger
compartment.

The air distribution in the passenger
compartment can be adjusted by combining the
use of several vents.

When the indicator lamp is off, air is taken from
outside the vehicle. When the indicator lamp is
on, the air inside the passenger compartment
is recirculated and the intake of air from outside
the vehicle is inhibited.

In cold weather with the engine cold,
the air flow is increased gradually until
the system has warmed up, in order
to limit the delivery of cold air into the
passenger compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfort value setting, there
is no need to alter the value displayed
in order to reach more quickly the
required level of comfort. The system
compensates automatically and
corrects the temperature difference.

This setting is associated with AUTO mode
only. However, on deactivation of AUTO mode,
the last setting remains on.
Changing the setting does not reactivate AUTO
mode if deactivated.

When the indicator lamp in the button is on, the
air conditioning system operates automatically:
the system manages the temperature, air
flow and air distribution in the passenger
compartment in an optimum way according to
the comfort level selected.
You can always choose to modify a setting
manually. In this case the indicator lamp in the
button is off.
F

Press this button again to activate the

automatic comfort programme again.

F Press this button to activate or

deactivate the automatic mode of
the air conditioning system.

Automatic comfort
programme

To change the current setting, press the button
to display the different modes in turn:

"SOFT": provides soft and quiet operation by
limiting air flow.

"NORMAL": offers the best compromise
between a comfortable temperature and quiet
operation (default setting).

"FAST": provides strong and effective air flow.

It is possible to modulate the intensity of the
automatic comfort programme by choosing one
of the mode settings offered in the secondary
page of the Air conditioning menu.

well as in STOP mode with Stop & Start.

Depending on equipment, it may contain:
- one 230 V socket,
- one 12 V socket,
-

one USB port,

- one auxiliary socket

In the event of a fault with the socket, the green
warning lamp flashes.
Have it checked by a CITROËN dealer or a
qualified workshop.

Connect only one device at a time to
the socket (no extension or multi-way
connector).
Connect only devices with class II
insulation (shown on the device).
As a safety measure, when electrical
consumption is high and when required
by the vehicle's electrical system
(particular weather conditions, electrical
overload...), the current supply to the
socket will be cut off; the green warning
lamp goes off.
