Weather was nice last couple of days. Underside of car and garage dry. So I thought I'd scope out the jacking situation. As @Paul Gregory mentioned in another thread, there is a fair amount of ground clearance, at least compared to my MINI. I just put a hockey puck in the cradle of my old 3.5 ton floor jack, pushed it under the front tire change jack point, and pumped away. It had to go a little high to get both wheels off the ground, which I usually did with my MINIs (short wheelbase). I may or may not do this when changing out snows. Anyway, a pleasant surprise.
There is a front jacking point, but I understand for gen 5 is pretty far back, about aligned with the front wheels. If you roll the front wheels up on low-rise ramps (say 3", a couple of layers of 2x...) it helps, both to get the jack under and to give enough clearance for the lever to get it started. With gen 5, just from what I've been reading here, Toyota's apparently FINALLY adding some reinforcement to the crimped seam at the front scissor jack location. So might be adequate for safety stands.
For any folks that might be interested, here is yet another way to jack up a gen5, using a heavy duty scissor jack: Another way to lift the gen5 | PriusChat
