AIR CONDITIONING The air conditioning filter is behind the glove box. The air conditioning filter may clog after long use. The filter may need to be replaced if the air flow of the air conditioner and heater experiences extreme reductions in operating efficiency, or if the windows become to fog up easily. If the symptoms of air conditioning efficiency problems occur, contact your nearest Lexus dealer to have the filter checked and replaced. To maintain the air conditioning efficiency, inspect and replace the air conditioning filter according to the maintenance schedule. In dusty areas or areas with heavy traffic flow, such as inner city or desert areas, early replacement may be required. (For scheduled maintenance information, please refer to the "Warranty and Services Guide/Owner's Manual Supplement/ Scheduled Maintenance".) 1. Open the glove box. Remove the 2 pins installed on the upper part of the glove box and lower the glove box. 2. Remove the filter case from the filter outlet as shown in the illustration. 303
