DUAL-ZONE DIGITAL AIR CONDITIONING

Automatic o
peration

We recommend the use of one
of the three AUTO modes avail-
able: they provide optimised
regulation of the temperature
in the passenger compartment
according to the comfort value that you
have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.

)
Press the "AUTO"
button repeat-
edly:


- a fi rst 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.
The air conditioning system operates when the engine is running. When the engine is cold, the air
fl ow 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 in-
terior temperature is much colder
or warmer than the comfort val-
ue, there is no need to change
the value displayed in order to
obtain the comfort required. The
system corrects the difference in
temperature automatically and
as quickly as possible.

1. Automatic comfort programme
This system is designed to operate ef-
fectively in all seasons, with the windows
closed.

Switching the system off

the left until all of the indi-
cator lamps go off.
This action switches off the air condi-
tioning and the ventilation.

ger 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.
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.
Even with the engine is off,
you can operate the ventila-
tion for a few minutes.
For example, while you are
away from the vehicle, the pas-
sengers can still enjoy some air circula-
tion without having the engine running.
This function is available after switching
on the ignition, as well as after stopping
the engine.
The period that the function is available
depends on the state of charge of the
battery.
You can activate the "REST" func-
tion while the air conditioning control
