3Changing the setting does not reactivate AUTO
mode if it 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.
Manual control
It is possible to manually adjust one or more
of these functions, while the system retains

Ventilation 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 period which depends on the
battery charge.
This function does not operate the air
conditioning.
Interior air recirculation

of mist on the windscreen and side windows.
Recirculating the interior air isolates the
passenger compartment from outside odours
and fumes and allows the desired passenger
compartment temperature to be achieved more
rapidly.
► Press this button to activate/deactivate
the function (confirmed by the
illumination/extinction of the indicator lamp).

using the camera may be affected.
Heated windscreen

In cold weather, this function heats the entire
windscreen and complements the Automatic
Visibility programme to speed up the evacuation
of elements that interfere with visibility (e.g.
dew,
mist, frost, snow), located on either side of the
windscreen.
It can be used both before setting off and while
driving.
