is filtered and originates either from the exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
The controls are accessible in the "
Air
conditioning " menu of touch screen
A.
The demisting/defrosting controls for the
windscreen and rear screen are located below
the touch screen.

Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►


Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in perfect working order

.
►

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, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air 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.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.
Servicing the ventilation and air
conditioning system
►

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

.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop & Start,
refer to the corresponding section.

flow settings and the air distribution in the
passenger compartment for a duration which
depends on the battery charge.
This function does not operate the air
conditioning.
Recirculation of interior air

eliminate misting of the windscreen and side
windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
Temperature adjustment
► Press one of the buttons 2 to decrease (blue)
or increase (red) the value.
The value indicated corresponds to a level of
comfort and not to a precise temperature.
For maximum cooling or heating of the
passenger compartment, press the
temperature setting button down or up until
LO or HI is displayed.
Automatic comfort programme
► Press the “ AUTO“ button 7 to activate
or deactivate the automatic mode of the air
conditioning system.
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 you have selected.
►

Go to the secondary page by pressing button
6

“OPTIONS ” to adjust the automatic comfort
programme by choosing one of the available
settings.
Mode AUTO► To change the current setting, press
the button several times in succession to
access the desired mode:
"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.
This setting is associated with AUTO mode only.
However, on deactivation of AUTO mode, the
last selected setting remains.
Changing the setting does not reactivate AUTO
mode if deactivated.
In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, 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 setting requested, 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 as quickly as possible.
You can manually adjust the air flow and distribution.
As soon as you modify a setting, the automatic
comfort programme is deactivated.

Panoramic glass sunroof

This glazed roof provides increased visibility
and light in the passenger compartment, while
maintaining normal temperatures thanks to its
"high thermal protection" coating.
Advice on care
In order to preserve the properties of the glazed
roof, we recommend wiping and cleaning the
inner glass using a clean, soft and dry cloth.
For stubborn stains, the glass should be cleaned
using screenwash fluid, rinsed with clean water,
then dried with a clean, soft cloth.
Do not use soapy water, abrasive
products, detergents (particularly those
with an ammonia base), solvents or solutions
with a high concentration of alcohol, petrol
etc.
