Ease of use and comfort  
"Normal": offers the best compromise between  
a comfortable temperature and quiet operation  
(default setting).  
"Fast": provides strong and effective air flow.  
This setting is associated with AUTO mode only.  
However, on deactivation of AUTO mode, the

passenger compartment, press the  
temperature setting button down or up until  
LO or HI is displayed.  
Avoid driving for too long without  
ventilation - risk of misting and  
deterioration of air quality!  
Changing the setting does not reactivate AUTO

In cold weather with the engine cold, the  
air flow is increased gradually until the  
comfort setting has been reached, in order to  
limit the delivery of cold air into the passenger  
compartment.  
On entering the vehicle, if the interior  
temperature is much colder or warmer  
than the comfort setting requested, there  
is no need to alter the value displayed in  
order to reach more quickly the required  
level of comfort. The system compensates  
automatically and corrects the temperature  
difference as quickly as possible.
