Ease of use and comfort

Dual-zone digital air conditioning

The air conditioning system operates when the engine is running.

Automatic operation

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 comfort value, 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

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

comfort value that you have

chosen.

This system is designed to operate effectively

in all seasons, with the windows closed.

F

Press the "AUTO" 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.

These three modes automatically adjust the

air flow, according to the desired setting, while

also maintaining the desired comfort value.

Turn control 2 or 3 to the left or to the right

respectively to decrease or increase this

value.

F

A setting around the value 21 provides

optimum comfort. However, depending on your

requirements, a setting between 18 and 24 is

normal.

You are advised to avoid a left / right setting

difference of more than 3.

For example, while you are away from the

vehicle, the passengers can still enjoy some air

circulation without having the engine running.

This function is available after switching on the
