AIR CONDITIONING If manual fan speed control is desired - If manual switching of air intake is desired - 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. Each time you push the air intake control button, the mode changes in order from the RECIRCULATED AIR mode to FRESH mode, then back to the RECIRCULATED AIR mode. Each indicator light shows which mode is now selected. 1 RECIRCULATED - Recirculates the air inside the vehicle. 2 FRESH - Draws outside air into the system. If quick circulation of cooled air is desired, push the air intake selector button for RECIRCULATED mode. For normal use, it is best to keep the air intake selector button set to the FRESH mode. If recirculated air is used during heating, the windows will fog up more easily. To prevent fogging up of the windshield, the air intake mode may change automatically to the FRESH 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 FRESH mode. This is not a malfunction. When the air conditioning is ON, if the engine coolant temperature becomes extremely high, the RECIRCULATED 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). 156
