First, I yank the E-Brake nice and hard, then chock the rear tires. My car is lowered, so I turn my steering wheel all the way and use a small jack on one of the front control arms, to lift the car up high enough to get my normal floor jack under the front middle. Then I raise the car carefully, not banging the front bumper with the jack handle and scoot the small jack out of the way. I then place jack stands under the front frame in a STABLE position and lower the car slowly onto the stands.
When jacking the car up, there are a few things to look out for:
If your hood is up, make sure it doesn't hit the ceiling of your garage or the garage door. It can get kinda high and if you aren't paying attention oyu may hit something up yonder....
Make sure you don't jack the car up too high you crush the rear bumper on the ground or on one of the wheel chocks.
You should have enough room to crawl around under there and have fun trying to figure out how to get the oil filter removal tool in there, lol! It is doable though, just work at it.
Good Luck -FROG-
