3-1. Using the air conditioning system and defogger n Plasmacluster™* (if equipped) Plasmacluster will operate in conjunction with the air conditioning fan motor when it is turned on. 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. To clean the driver's side vent, turn the system off and wipe the vent using a soft cloth. *:Plasmacluster technology is manufactured under license from the SHARP Corporation. "Plasmacluster™" is a trademark of the SHARP Corporation. n Air conditioning odors Interior features 3 l During use, various odors from inside and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to be emitted from the vents. l To reduce potential odors from occurring: • It is recommended that the air conditioning system be set to outside air mode prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic mode. CAUTION n To prevent the windshield from fogging up Do not use during cool air operation in extremely humid weather. The difference between the temperature of the outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your vision. n Plasmacluster™ Do not disassemble or repair the system because it contains high voltage parts. Call your Toyota dealer if the system needs repair. 289 PRIUS_U (OM47685U) DVD
