Automatic operation
1. Automatic comfort programme
We recommend the use of one of
the three AUTO modes available:
they provide optimised regulation of
the temperature in the passenger
compartment according to the comfor t value
that you have chosen.
These three modes automatically adjust the
air flow, according to the desired setting, while
also maintaining the desired comfort value.
)
Press the "AU TO "
button repeatedly:
- a first indicator lamp comes on; the
"light" setting mode is selected,
- a second indicator lamp comes on; the
"medium" setting mode is selected,
- a third indicator lamp comes on; the
"intense" mode setting is selected.
When the engine is cold, the air
flow will reach its optimum level
progressively, taking account of the
weather and the desired comfort level
so as to avoid too great a distribution
of cold air.
On entering the vehicle, if the interior
temperature is much colder or warmer
than the comfor t value, there is no
need to change the value displayed in
order to obtain the comfor t required.
The system corrects the difference
in temperature automatically and as
quickly as possible.
This system is designed to operate effectively
in all seasons, with the windows closed.
