I took my 2015 Prius Four to the dealer today because my battery had to be replaced. When I drove the car away, a driver's seat heater was on. I didn't think the car had seat heaters! I cannot for the life of me find anything that would turn a seat heater on/off.
Toyota owners manuals for your car are here. 2015 Toyota Prius Owners Manual and Warranty - Toyota Owners
There should be a light next to it that shows the driver if the passenger heater is on or off also. Have you found the lumbar control? It's on the left side of the seat bottom, a round dial that on a better seat would move the lumbar up and down but on prii just inflates and deflates.
But I thought people reading their owner's manual was against the rules? I mean if everyone reads the owner's manual most of the Prius forums for the newest models would no longer be used for anything... Make PriusChat great again... Burn your owner's manual!!!
The center console between the two seats has been one blunder on top of the next for years... People who are 6 feet or taller don't fit in this space and removing the center console and replacing it with a pillow entirely solves that problem on 2004-2009 and 2016-2018 Prius, but if you own a 2010-2015 Prius, not counting the Prius V, you're pretty much trapped inside too small of a plastic box that you can't very easily get rid of without destroying & rebuilding much of the dash where it connects to center console. As I've said before, the lack of competition with Prius at its peak sales, led to Prius designers going way off course starting in 2010 and I suspect based on how fast they've lost market share to much nicer looking overall designs, the Prius line will likely be discontinued in 2 or 3 years...
They put the buttons side-to-side on Prime (and Gen4?), so that passenger side button can not be reached by driver.
They are side by side on mine. But not visible from a normal driving position. I have to scrunch down to see the driver's side switch and really contort to see the passenger side.
