AIR CONDITIONING (i) Outside temperature display (j) Plasmaclustert∗ Outside temperature is displayed on the screen. The displayed temperature ranges from −40_F (−40_C) up to 122_F (50_C). If the temperature shows "− −" or "E", take your vehicle to your Lexus dealer. In the following situations, the correct outside temperature may not be displayed, or the display may take longer than normal to change. D When stopped, or driving at low speeds (less than 15.5 mph [25 km/h]) D When the outside temperature has changed suddenly (at the entrance/exit of a garage, tunnel, etc.) Select the Plasmaclustert button on the display. The indicator light is on when the Plasmaclustert is operating. This air conditioning system adopts plasmacluster technology, which helps to keep good air quality in the cabin by emitting positive and negative ions through the driver's side vent. A slight noise may be heard during operation. This is not a malfunction. Also, static electricity may be discharged near the driver's side vent due to the high voltage used to operate the system. 287
