Heating and
Ventilation
Controls
The incoming air follows various routes
depending on the controls selected by
the driver, the front passenger and rear
passengers, according to the level of
equipment.
The temperature control enables you to obtain
the level of comfort required by mixing the air of
the various circuits.
The air distribution control enables you to
select the air vents used in the passenger
compartment by the combined use of the
associated buttons.
Air intake
The air circulating in the passenger
compartment is filtered and originates either
from the outside via the grille located at the
base of the windscreen or from the inside in air
recirculation mode.

Recommendations for ventilation and air conditioning
In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F
I
f the interior temperature remains very high after the vehicle has been parked in the sun for
a considerable time, first ventilate the passenger compartment for a few minutes.
P

lace the air flow control at a sufficient level to provide an adequate renewal of air in the
passenger compartment.
F

T
o 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

I
n normal conditions, use the intake of exterior air as prolonged use of the air
recirculation may cause misting of the windows and side windows.
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 5 to 10 minutes, once or twice a month to keep it
in good working order.
F

E
nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly (refer to the "Checks" section).


W
e recommend the use of a combined passenger compartment filter. Thanks to its
second special active filter, 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
he air conditioning uses power from the engine while operating. This results in an
increase in the vehicle's fuel consumption.
W

hen towing at or near maximum capacity or on steep slopes in high ambient
temperatures, switching off the air conditioning saves engine power and so improves
towing capacity.
C

ondensation created by the air conditioning results in a discharge of water under the
vehicle when stationary, which is per fectly normal.
F

T
o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly.
F

I
f the system does not produce cold air, do not use it and contact a PEUGEOT dealer or
a qualified workshop. The air conditioning system does not
contain chlorine and does not present
any danger to the ozone layer.

passenger compartment from exterior odours
and smoke.
Return to exterior air intake as soon as possible
to prevent deterioration of the air quality and
demisting performance.
3. Air distribution adjustment

Dual-zone digital air conditioning
We recommend the use of this mode: it permits
automatic and optimised adjustment of all
of the functions, passenger compartment
temperature, air flow, air distribution and air
recirculation, in accordance with the comfort
value that you have chosen.
This system is designed to operate effectively
in all seasons, with the windows closed. The value indicated in the screen corresponds
to a level of comfort and not to a temperature in
degrees Celsius or Fahrenheit.
1. Automatic comfort programme
To prevent too great a distribution of
cold air when the engine is cold, the
air flow will reach its optimum level
gradually.
In cold weather, it favours the
distribution of warm air to the
windscreen, side windows and footwells
o n l y.
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
more quickly. The system corrects the
difference in temperature automatically
and as quickly as possible.
