Continue driving slowly up the ramps until your vehicle levels out, and then stop immediately.

You can either find the correct place to stop purely by feel, or you can have a friend spot you from outside the vehicle.

If you don't make it all the way up the ramps on the first try, that's okay—it can take several tries to get a feel for how the vehicle responds on the ramps. Let it roll back down, stop at the bottom, reposition the ramps and try again.
