On stopping the engine
- While the control screens remain
on: the function is available.
- Pressing the REST button activates
the ventilation for a few minutes.
Activation of the function is con-
fi rmed by the display of two dashes
in the control screens and four air
3
fl ow level indicator lamps.
Locking the vehicle has no effect on
this function.
- The control screens go off at the
end of this period.
Pressing again before the end of
the period interrupts off the ventila-
tion defi nitively: the control screens
go off and the function is no longer
available.
This switch does not operate the
air conditioning, only the air fan.
When the "REST" function is ac-
tivated, you cannot modify the
temperature, air fl ow and distri-
bution settings: these are con-
trolled automatically according
to the ambient temperature.
This function is not available in
the STOP mode of Stop & Start.

Switching the system off
 Turn the air fl ow control to
the left until all of the indi-
cator lamps go off.
This action switches off the air condi-
tioning and the ventilation.
Temperature related comfort is no long-
er assured but a slight fl ow of air, due
to the movement of the vehicle, can still
be felt.
 Modify the settings (temperature,
air fl ow or air distribution) or press
the "AUTO" button to reactivate the
system with the values set before it
was switched off.
Avoid prolonged operation in in-
terior air recirculation mode or
driving for long periods with the
system off (risk of misting and
deterioration of air quality).
