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
o r d e r.
F

E
nsure 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). If after an extended stop in sunshine,
the interior temperature is very high,
first 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.
To maintain a
comfortable temperature
in the passenger compartment, you may
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.
F

T

o 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

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.

Automatic comfort
programme
F Press the " AUTO" button 6 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.
F Go to the secondary page by pressing button 8 " 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 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 automatically
corrects the temperature difference as
quickly as possible. You can always choose to change a
setting
manually. In this case, the automatic comfort
programme is deactivated.
