When the mode is selected, the air conditioner automatically turns on if the outside temperature is more than slightly above freezing. This dehumidifies the air which helps defog the windscreen. The air recirculation mode automatically turns off, allowing outside air to be drawn into the passenger compartment to further improve the defogging performance.
The air conditioner system should be operated for approximately 10 minutes at least once a month. This helps prevent damage to the air conditioner system due to the lack of lubrication.
A visible mist may be seen coming from the vents in hot, humid conditions as the air is cooled rapidly. This does not indicate a malfunction.
If the engine coolant temperature becomes too high, the air recirculation mode will be activated and the indicator light will turn on automatically.
If the engine coolant temperature gauge indicates engine coolant temperature over the normal range, turn the air conditioner off. (See
