Ease of use and comfort
3The setting is associated with AUTO mode only.
However, when AUTO mode is deactivated, the
previous selection is retained.
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 reach
the required level of comfort more quickly.
The system automatically corrects the
temperature difference as quickly as possible.
Air flow adjustment
► Press one of the buttons 2 (- or +) to increase
or decrease air flow.
The air flow symbol (a fan) is filled in according
to the request.
When the air flow is reduced to a minimum,
ventilation stops.
"OFF " is displayed alongside the fan.
Adjusting the air distribution
► Press the buttons 3 to adjust the air flow
distribution inside the passenger compartment.
Windscreen.
Central and side air vents.
Footwells.
Each press on a button activates or deactivates
the function.
All three buttons can be activated simultaneously. In this case, priority is
given to the air flows from the central and side
air vents, and from those in the passenger
footwells.
Air conditioning on / off
The air conditioning system is designed to
operate effectively in all seasons, with the
windows closed.
It is used to:
– lower the temperature in summer ,– increase the effectiveness of the demisting in winter, above 3°C.
► Press button 4 to turn the air conditioning on/
off.
When the indicator lamp is on, the air
conditioning function is activated.
The air conditioning cannot operate when the air flow adjustment is set to OFF.
Ventilation function with the
ignition on
When the ignition is switched on, you can
use the ventilation system to adjust the air
flow settings and the air distribution in the
passenger compartment for a duration which
depends on the battery charge.
This function does not operate the air
conditioning.
Recirculation of interior air
The intake of exterior air helps avoid and
eliminate misting of the windscreen and side
windows.
Recirculating the interior air isolates the
passenger compartment from exterior odours
and fumes.
When required, this function also allows
faster heating or cooling of the air in the
passenger compartment.
► Press button 6 to recirculate the interior air or
allow the intake of exterior air.
Avoid prolonged use of interior air recirculation (due to the risk of misting
and deteriorating air quality).
