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.

These three modes automatically adjust the

air flow, according to the desired setting, while

also maintaining the desired comfort value.

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.

This system is designed to operate effectively

in all seasons, with the windows closed.

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.
