nsure that the cabin filter is in good
condition and have the filter elements
replaced regularly.
We recommend the use of a
combined
cabin 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).

few
moments. Then return to the intake of
exterior air.
Switching off the air conditioning may result
in some discomfort (humidity, misting).

system.
When the indicator lamp in the button is on, 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.
It is possible to adjust the intensity of the
automatic comfort programme by choosing one
of the settings offered in the secondary page,
accessible from button 11 "OPTIONS ".
To change the current setting, shown by
illumination of the corresponding indicator
lamp, press button 13


repeatedly until the
desired mode is displayed:
" 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.
Use the " Normal" or "Fast" modes to ensure
the comfort of passengers in the rear seats.
This setting is associated with automatic mode
only. However, on deactivation of AUTO mode,
the indicator lamp for the last setting remains
on.
Changing the setting does not reactivate AUTO
mode if this was 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
to more quickly reach the required level
of comfort. The system automatically
corrects the temperature difference as
quickly as possible.Automatic visibility

"Air Quality System " (AQS)
function
Using a pollution sensor, this function
a utomatically activates recirculation of the
interior air once a
certain level of polluting
substances in the exterior air is detected.
When the air quality returns to a
satisfactory
level, recirculation of interior air is automatically
deactivated.
This function is not designed to detect
unpleasant odours.
Recirculation is automatically activated when
the front screenwash is used or when reverse
gear is engaged.
The function does not operate if the exterior
temperature is below 5°C, to avoid the risk of
misting of the windscreen and side windows.
To activate or deactivate the function, go
to the secondary page by using button 11

windows.
The system allows the manual modification of
air flow without causing automatic deactivation
of the automatic visibility programme.
With Stop & Start, when demisting –
defrosting has been activated, STOP
mode is not available. In wintry conditions, remove all snow or
ice on the camera on the windscreen
before moving off.
Other wise, this can affect the function
of the equipment associated with the
camera.
Heated windscreen
In cold weather, this system heats the bottom of
the windscreen, as well as the areas alongside
the windscreen pillars.
Without changing the settings for the air
conditioning system, it allows faster release
of the windscreen wiper blades when they
are frozen to the windscreen and helps avoid
the accumulation of snow resulting from the
operation of the windscreen wipers.
Switching on/off

Additional Heating/
Ventilation
Heating
This is an additional and separate system
which heats the passenger compartment and
improves defrosting performance. This indicator lamp is lit while the
system is programmed or set in
operation remotely via the remote
control.
It flashes during the whole duration
of the heating and goes off at the end
of the heating cycle or when stopped
using the remote control.
Ventilation
This system allows ventilation of the passenger
compartment with exterior air to improve the
temperature experienced on entering the
vehicle in summer.

F
U
se a coin to unscrew the cap and replace
the battery. Do not throw remote control batteries
away as they contain metals which are
harmful to the environment. Take them
to an approved collection point.
The maximum heating period is about
45 minutes depending on the climatic
conditions.
The additional heating system is powered
by the fuel in the vehicle's fuel tank.
Before use, ensure that there is enough
fuel in the tank.
If the tank level is on reser ve, the system
cannot be used.
The ventilation is activated provided that
the battery is sufficiently charged.
The heating is activated provided that:
-

t
he battery is sufficiently charged,
-

t
he fuel level is adequate,
-

t
he engine has been started since the
previous heating cycle. To avoid the risks of poisoning or
asphyxia, the programmable heating must
not be used, even for short periods, in
a
closed environment such as a garage or
workshop which is not equipped with an
exhaust gas extraction system.
Do not park the vehicle on a
flammable
sur face (dry grass, dead leaves, paper,
etc.) – risk of fire!
Glazed sur faces such as the rear screen
or windscreen can become very hot in
places.
Never put objects on these sur faces;
never touch these sur faces – risk of burns! Always switch off the additional heating
while refuelling – risk of fire or explosion!
The indicator lamp in the remote control
flashes for about 2 seconds if the vehicle
has not received the signal.
You should then move to a different
location and repeat the command.
Switching off
F Pressing and holding this button stops the heating immediately
