Automatic Air Conditioning Controls If manual fan speed control is desired If manual switching of air intake is desired To prevent fogging up of the windshield, the air intake mode may change automatically to the OUTSIDE AIR mode depending on the condition of the air conditioning system. For example, when the ambient temperature is low, the air intake mode may change automatically to the OUTSIDE AIR mode. This is not a malfunction. When the air conditioning is ON, if the engine coolant temperature becomes extremely high, the RECIRCULATED AIR mode is automatically selected. This is not a malfunction. When the engine coolant temperature is lowered, the previous mode resumes. If manual on-off of the air conditioning is desired Touch the "A/C" switch to turn the air conditioning on and touch it again to turn the air conditioning off. The air conditioning does not work if the outside temperature is lowered down to around 0_C (32_F). UNG506 NRY016 " 1 Fan speed at low 2 Fan speed at high The fan speed can be set to your desired speed by touching the appropriate air flow control switch. The higher the fan speed is, the more air is delivered. Pushing the "OFF" button turns off the fan. To remove the exterior windshield frost and interior windshield fog, use the high speed setting. The selected mode is highlighted in green. The air intake control button is used to switch the air intake between the OUTSIDE AIR mode and RECIRCULATED AIR mode. With the button in the OUTSIDE AIR mode, the indicator light will turn off and the system will take fresh outside air into the vehicle. If quick circulation of cooled air is desired, push the air intake control button for RECIRCULATED AIR. The indicator light will come on. For normal use, it is best to keep the air intake control button set to the OUTSIDE AIR mode. If recirculated air is used during heating, the windows will fog up more easily. 135
