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
uncomfortable, 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 system checked on a regular basis. See
"Maintenance and Warranty 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.
