AUTOMATIC AIR CONDITIONING
The system has a differentiated adjustment for the driver's side and passenger's side, in terms of temperature andair distribution. The air fl ow is common to both sides.
Symbols and messages relating to the automatic air conditioning controls will display on the multifunction screen.
2. TEMPERATURE ADJUSTMENT
To adjust the temperature, press button 2a for the driver'sside and button 2b for the passenger's side.
An ad
justment around 21 will give you the optimumcomfort level. However, depending on your preferences
anywhere between 18 and 24 is quite usual.
Operating the air conditioning system on"AUTO"guar-
antees good ventilation inside the cabin.Note:there may be a difference between the actual
cabin temperature and the fi gure displayed.
This is the normal operatin
g mode for the system. Depending on the temperature chosen, a press on this
button, confi rmed by the lighting of the warning lamp,
will automatically and simultaneously bring all the fol-lowing functions into play:Air fl ow.
Cabin temperature.
Air distribution.Exterior air intake/Air recirculation.
It is recommended to keep all the air vents open. Just by pressing any of the buttons, except for temperature 2aand 2b, you can change to manual mode. The warning lamp goes off, and the automatic air intake function is deactivated.

AUTOMATIC AIR CONDITIONING
Remarks:When starting from cold, in order to prevent
unwanted cold air, the air fl ow will increase onlygradually to its optimum level.
If you enter the vehicle after a fairly prolongedstop and the temperature inside the vehicle is far from comfortable, it serves no purpose to modify
the temperature that is displayed as an attempt
to go immediately to the desired comfort level.
The system automatically uses all of its power tocompensate the temperature gap as quickly as possible.
Remarks:Water arising from the condensation in the air conditioning drains out through a hole provided for this purpose; a pool of water may thus form
underneath the vehicle when stationary.
Whatever the time of year, even in cool weather the
air conditioning is useful in removing humidity and
misting.
You are advised to have the air conditioning systemchecked on a regular basis. See "Maintenance andWarranty Guide".
If you are towing a heavy trailer and outside
temperatures are high, the air conditioning may be
temporarily paused if the engine cooling requires this.
