In this video, we learn how to change the temperature settings in a 2010 Prius. All the climate controls are on the center console. The steering wheel can also help you change the temperature control. Press the green switch first then you will be able to set the temperature that you want the car to be. The system will then maintain that temperature. If you want to use the fan, select the fan and then select the speed you want it to be at. There is also a front and rear defroster you can press when there is cold weather or the windows are fogging on the inside.
