AIR CONDITIONING Operating the two-temperature selector - The air conditioning system has two independent temperature selectors: left and right (for the use of driver and front passenger respectively). D There are cases where the temperature of the airflow may not be the same on the driver and front passenger side according to circumstances, even if the left and right temperature selectors are set at the same temperature. If this situation occurs, use the fine tuning operation to adjust the air temperature on one side. D There are cases where one or both of the airflow temperatures may not accurately reflect the set temperature, when the airflow temperature settings on the left and right are substantially different. For example, if the left controller is set at a moderate temperature while the right controller is set at maximum heating or maximum cooling, or vice versa. If this situation occurs, use the fine tuning operation to adjust the air temperature on each side. SETTING OPERATION - manual control When one of the manual control touchscreen buttons is depressed while operating in automatic mode, the operation corresponding to the depressed button is set. Other conditions continue to be adjusted automatically. To manually select air flow modes - The outlets from which air is delivered can be selected manually by touching the touch-screen button. The function of each mode is as follows: 1 Panel - Air flows primarily from the instrument panel vents and rear vents. 2 Bi-level - Air flows from the floor vents, instrument panel vents and rear vents. When you set the temperature selector setting during automatic operation, warm air flows out of the floor vents and cooler air flows out of the instrument panel vents and rear vents. 292
