80 Instruments and controls Automatic climate control (ACC) The air is drawn in through an intake at the bottom edge of the windshield. It passes through an efficient filter before being routed through the climate-control system and into the cabin. The cabin discharge vent is located on the right behind the rear bumper. The air discharge vents should be kept free of snow and ice in the winter. ACC (Automatic Climate Control) automatically maintains the desired cabin temperature, regardless of the weather outside. The system will achieve the desired temperature in the quickest possible way. Note that heating or cooling is not speeded up by setting the temperature higher or lower than you really want. For the ACC system to be most effective, all windows, and the sunroof if there is one, must be closed, and the panel vents must be open. The incoming air is treated in three stages: first it passes through a filter; it is then dehumidified and cooled and, finally, if required, heated. Air vent at rear side window IB794 Dash vent 1 Adjusting the direction of the air flow. 2 Adjusting the air flow The temperature interval within which you can make adjustments is 58-82°F (15-27°C). Outside it, there is the HI position (max. heat and high fan speed) and the LO position (max. cooling and max. fan speed). The displayed temperature is not the actual temperature but corresponds to the comfort level normally experienced at that temperature after allowance has been made for the air flow, relative humidity, solar radiation, etc., currently prevailing inside the car. • The most usual temperature setting is 66-74°F (19-23°C), depending on personal preference and what clothing is worn. • It is recommended that changes in the temperature setting be made in steps of 2°F (1°C). • Conversion between °C and °F is done in the SID unit; see "Units and language versions", page 69. • During the cooling phase in warm weather the panel vents must be open. • Do not manually select recirculation in cold/wintery weather. The reduced air flow can cause misting and ice on the inside of the windows. IB032
