The air ventilation seats are provided to cool the front seats by blowing air through small vent holes on the surface of the seat cushions and seatbacks.
When the operation of the air ventilation seats are not needed, keep the switches in the OFF position.
While the engine is running, push the switch to cool the driver's seat or the front passenger's seat.
• The air ventilation seats default to the OFF position whenever the ignition switch is turned to the ON position.
