Automatic Air Conditioner Fully automatic air conditioning combines with a carefully designed ventilation system to optimize interior comfort at all times.     Vacuum Fluorescent Display (VFD) The VFD features dial-type switches for accurate control of cabin temperature and airflow, plus an easy-to-read display of temperature, airflow and airflow direction.     Air Quality Control System Pollutants in the external air (carbon monoxide, various hydrocarbons, etc.) are detected and prevented from entering the vehicle cabin.     Manual Air Conditioning Functional and simply operating panel is applied for fresh interior atmosphere.     Roof Ventilation Air ducts in the top of the cabin improve heating and air conditioning effectiveness in the back seats     Rear Air Conditioning Control Unit Second-row passenger can adjust air conditioning (when Rear Air Conditioning switch in front is in “R” position).     Fully Closable Vent The vent grille can be closed completely when the heater/air conditioner unit is not in use.     Electric PTC (Positive Temperature Coefficient) Heater A separate electric system to warm up outside air that enters the cabin from outside is installed in front of the regular heater air vents, enhancing overall heating efficiency.     High-performance Fuel-fired Auxiliary Air Conditioning A tiny amount of fuel is burned upon ignition to heat up the coolant in the heating system quickly. The unit is installed in the coolant duct. The advantage of the option is that heater performance is improved for instantaneous cabin warmth in cold weather.
