RX350_Navi_U (L/O 0612) 272 AIR CONDITIONING To remove frost or exterior fog on the windshield- 1. Push the "TEMP" (" ") button to set the "HI". 2. Push the windshield air flow button. When the windshield air flow button is pushed, air flows mainly from the windshield vents and turns on the defogging function with the purpose of clearing the front view. Pushing the windshield air flow button turns on the defroster-linked air conditioning. At this time, the indicator of "A/C" comes on regardless of whether or not "A/C" is touched in. This is to clean up the front view more quickly. Pushing this button once again returns the air flow mode to the last one used. This button automatically changes the air intake mode to select the OUTSIDE AIR mode. This clears the front view more quickly. It is not possible to return to RECIRCULATED AIR mode when the windshield air flow button is on. (c) Outside temperature display Outside temperature is displayed on the screen. The displayed temperature ranges from -30 _C (-22_F) up to 50_C (122_F). If the temperature shows "- -" or "E", take your vehicle to your Lexus dealer. CAUTION Do not use the windshield air flow button during cooled air operation in extremely humid weather. The difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up blocking your vision.
