Generally the front and rear jack point locations on a vehicle is clearly provided to the owner. Either the owner’s manual, repair manual, and/or service manual will give you all of the locations on the vehicle where it is safe to use a floor jack or jack stands. For the 5th generation Honda Odyssey (years 2018-2023), you do have the jack stand locations outlined in the owner’s manual. But, when you are trying to find out where you can safely use a floor jack, this information is unavailable.
