Just got our first Prius last night. The one we got has the SPVS system. My question is, can I just leave the button on all the time?
Yup. Just remember to turn it off if you're in a dusty area (e.g. gravel road nearby) to reduce the amount of dust inside or if you're at the beach and ppl are BBQing with charcoal or wood (unless you're ok with an interior smelling like ash haha).
