Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the 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.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic 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

R
eplace the filter elements 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

T
o ensure correct operation of the air
conditioning system, have it checked
according to the recommendations 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.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d
o not drive for too long with the
ventilation switched off.
-

d
o not keep air recirculation set for an
extended period. 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.
The condensation created by the air
conditioning results in a discharge of water
under the vehicle which is per fectly normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
Temporarily deactivate the Stop &
Start system to maintain a comfortable
temperature in the passenger
compartment.
For more information on Stop & Star t ,
refer to the corresponding section.

the settings that were previously in use. Avoid driving for long periods with
the system off – Risk of misting and
deterioration of air quality!
Automatic air conditioning
The air conditioning operates with the engine
running, but the ventilation and its controls are
available with the ignition on.
Operation of the air conditioning and regulation
of temperature, air flow and air distribution in
the passenger compartment are automatic.

Mode AUTO
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.
F

G
o to the secondary page by pressing
button 6 " OPTIONS " to adjust the automatic
comfort programme by choosing one of the
available settings.
F

T
o 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 setting used remains set.
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.

Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculation of the interior air isolates the
passenger compartment from exterior odours
and fumes.When so required, this function also
allows faster heating or cooling of the air
in the passenger compartment.
F

P

or to permit the intake of outside air.
Avoid the prolonged use of interior
air recirculation – Risk of misting and

Panoramic glazed 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 preser ve the properties of the
glazed roof, we recommend wiping or 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,
solutions with a high concentration of
alcohol, petrol, etc.
