One day while we were bored in a F150 we figured out it just matches whatever that side the person in the front has it set to. So with dual zone one side in the rear could be heat and one could be cool depending on what is set up there. Dont know if you have to have floor air on though.
I read it as you can only get spray in liner with either lux package or first edition package. Adding a spray in liner without the lux won't be scheduled at least for the first 3 weeks.
