* (if equipped)
Plasmacluster will operate in conjunction with the air conditioning fan motor

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.

into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.

• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
