Automatic operation
1. Automatic "comfort" programme
Press the "AUTO" button. The "AUTO" symbol is displayed. We recommend that you use this mode. It provides optimised automatic control of all of the following functions: passenger compar tment temperature, air flow, air distribution and air intake, in accordance with the comfor t value that you have chosen. This system is designed to operate effectively in all seasons, with the windows closed.
For your comfor t, when the engine is switched off, the settings are retained
until the engine is switched on again. To prevent too great a distribution of cold air when the engine is cold, the air flow will only reach its optimum level gradually.
2. Temperature adjustment
The value indicated on the display corresponds to a level of comfor t and not to a temperature in degrees Celsius or Fahrenheit.
On entering the vehicle, if the interior is very cold or hot, there is no need to
change the value displayed in order to reach the required level of comfor t. The system corrects the temperature difference automatically and as quickly as possible.
Press the "" and "" buttons to change this value. A setting around the value 21 enables optimum comfor t to be obtained. However, depending on your requirements, a setting between 18 and 24 is usual.
