Remarks:When starting from cold, in order to prevent unwanted cold air, the air fl ow will increase only gradually to its optimum level.
If you enter the vehicle after a fairly prolonged stop 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 to compensate 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.
