Start-up transient strategy (cold engine)
The start-up transient strategy is a special operating method designed to ensure comfort to occupants also when the passenger compartment heating system is not able to work.

Air distribution
For computing air distribution, the automatic climate control system considers the air temperature at vent outlet,
given the general rule that in order to ensure comfort air should come out from the “lower” vents as the temperature increases. In particular: • Z L W K Z D U P D L U 7 7 ! ƒ & W K H D L U À R Z V K R X O G U H D F K W K H S D V V H Q J H U I U R P W K H X S S H U D Q G O R Z H U Y H Q W V + ( $ 7

Compressor
The compressor is switched off by the system when the temperature inside the evaporator reaches values which
may lead to the formation of ice since this could affect the proper operation of the system.

The compressor will always be switched on in MAX-DEF mode and will automatically be switched off during normal operation under the following conditions: •fan off;
• HI system status.
An error concerning the frost sensor (short circuit or open circuit) will cause the compressor coupling disconnection. The compressor will be automatically restarted by the system when normal conditions are restored.
The compressor will be activated for a few seconds every 30 minutes to ensure lubrication also when it is off.
