Residual heat function J
This function allows the user to maintain the
temperature set for the passenger compartment
for a certain time (15 minutes), even after the
key has been turned to STOP. To activate this
function, push the “REST” button before turning
the key to STOP.
Once selected, this function is activated when
the key is turned to STOP and sets the following
features:
- bilevel air distribution
- compressor deactivation
- minimum fan speed
- air recirculation activation
- water recirculation pump activation
The system is deactivated after 15 minutes or
when the key is turned to MAR.
In addition, the REST function will be disabled
(if active), when the battery voltage is below
11.5V. When the outside temperature is above
25°C it will not be possible to activate the
function.

Air recirculation switch F

the air flow comes from the outside.
When outside temperatures exceed 35 °C,
the air recirculation option remains on with a
120-second pause every twenty minutes, to
refresh the air.

The air flow comesfrom inside the passenger
compartment.
The recirculation speeds up air heating or

windscreen defogging/demisting.
To deactivate this function, press the switch.

Defogging/demisting switch
H for rear window and
external rear-view mirrors
It is activated by operating the switch
H and
activation is signalled by the LED.
If it is not deactivated within thirty minutes
after activation, this function deactivates
automatically.
It is however advisable to deactivate it once the
defogging/demisting process is complete.
Once the internal temperature has stabilised at
the desired level, you are advised not to change
the position of the selector unless the external
temperature changes drastically.
A change in the position of the temperature
selection switch will involve a difference
between temperature inside the passenger
compartment and the air coming out of the
vents. This difference will gradually decrease as
the system works at full, stabilised speed.
