Please show me where the floor jack suppose to go!

I don't have a Prime, but this is just red-flag for me lol. You should not be having problems finding that rear jacking point, it's a bodywork protrusion, directly next to the rear suspension linkage. I think I can even dig up a pic (I was crawling under a 4th gen demo at a local dealership, I'm funny about that). Well not quite, but close, just beyond the frame, right over thar:



Front appears to be a little more subtle. But some clues: it'll be central, it'll be just about the reach of a medium sized floor jack, and it'll be a substantial piece of metal. Some bigger blow-ups from the manual:





A lot of clues there I think. Looks to be just aft of the plastic zone, and there's some distinct looking pieces to orient yourself.

One thing on our third gen, there's an opening on the engine underpanel at the jacking point, and a big embossed arrow on the panel pointing towards the jacking point. There might be something similar on 4th gen?

Note the text too:



On third gen it's a spot on the underside of the lower cross-beam. It seems to be the same on fourth gen.

I appreciate the weather hasn't been to kind on the east coast, maybe that's a factor. Are you out in a driveway??

 

Whoops look at my other post

 

Here's a screen-grab from a 4th gen (2016) walk around video. Judging from the owner's manual pictures, I'm gonna say here:

And the rear point:

If you're using jack stands, unless they've improved substantially compared to third gen, I'd be looking for some alternates, something near the official scissor jack location, but heavy gauge steel, and not a vertical knife edge.

 

I put mine on the side of the car next to the tire the owners manual says that is the correct place

I put my hydraulic jack next to the tire on the side of the car the owners manual even says this works its on page 619

 

The owner's manual says to put the scissor jack there, not a floor jack.

If you put the scissor jack at those locations, I think you'll see it just cups around that crimped edge, actually bears on the body behind the crimped edge. I use the scissor jack once on a rear location, it bears on the bodywork, and managed to dimple it a bit, with one use.

 

Well I thought it was, as it was so on 3rd gen. But it might be a protrusion on the suspension piece, with 4 th gen. It is pretty apparent, in between those two rear linkage arm pivots, much nearer the driver side.

It's easy to see: you just need to crawl under there in the freezing slush.

 

I find on our 3rd gen with a 3 ton floor jack, if roll it under the front, not quite central, a little towards the driver's side, as far as it'll go until the (vertical) jacking handle bumps against the front "bumper", then pull the hand back slightly, roll the jack in a bit more, then flop down on a piece of carpet, check location with a lamp, I'll be pretty close, need to maybe nudge it slightly.

 

For tire rotations I like to raise the whole car and put on jack stands (on a flat slab in garage), with as little clear between the tire and the slab as possible, less than an inch for sure. I used to just squat and lift the wheel up and on, but my back is telling me to stop doing that, so now I zig-zag the wheel up then lever them up and on with a pry bar at the underside to lift. It helps to have someone holding a light over your shoulder, to align the studs with holes.

 

And the tire shops I've been to? If they don't put the car on a lift, they just roll up two floor jacks and place one behind the front right wheel, and one in front of the right rear wheel.... Without looking at anything underneath.... And lift. Then repeat on the left side.

They place the jacks in the same position on all types of vehicles. I guess it's ok, my Prius is still rolling. I felt along the lower body sides, and never noticed any dents or damage.

 

I just mounted my snows yesterday.
The front point is behind the front tire, a low profile jack, just behind the tire, there's metal there that the jack can engage, a round frame part with a nut in the middle, perfect spot, the rear like the Gen 2 and 3 is a metal protrusion in the center behind the rear axle.


Jacking a unibody by the unibody, hahaha.

 

Wait a sec: you didn't have it up in the air and crawled under, within a week of purchase? That's all the fun.

 

I did that with the wife’s RX450h .

She wasn’t too keen on that.
