Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the

46
Ease of use and comfort
windscreen, or from the inside in air recirculation
mode.
Controls
Depending on version, the controls are
accessible in the Climate touch screen menu
or are grouped together on the centre console
panel.
Air distribution

1. Windscreen demisting/de-icing vents
2. Front side window demisting/de-icing vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents
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 good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large 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. Its specific active additive
helps protect against polluting gases and bad
smells.
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
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.
