Heated seats control

Do not use the function if the seat is not
occupied.
Reduce the level of heating as soon as
possible.
Once the seat and passenger
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, ...).
There is a risk of overheating the

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

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.

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
perfectly 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 & Start, refer to the corresponding section.

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 If 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

Turn the dial from position 1 to position 5 to

obtain a comfortable air flow.

Windscreen and side windows.

Windscreen, side windows and
footwells.

Footwells.

4. Air intake / Air recirculation

The intake of exterior air prevents the formation
of mist on the windscreen and side windows.

F Press the button to recirculate

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:
- lower the temperature, in summer,
- increase 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.

F

Press the button again to

permit the intake of exterior air.
The indicator lamp goes off to
confirm this.

Switching off

F Press the "A/C" button, the

button's indicator lamp comes on.

Dual-zone digital air conditioning

The air conditioning system operates when the engine is running.

Automatic operation

1. Automatic comfort programme

F Press the "AUTO" button

repeatedly:
- a first indicator lamp comes

on; the "light" setting mode is
selected,

- a second indicator lamp

comes on; the "medium"
setting mode is selected,

- a third 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.
