You begin looking into a door into a kitchen area. Turn to your right past the thermostat, and you should see a door into a mostly empty area. Proceed through this doorway and towards the very thin pillar. Once you're next to the very thin pillar look to the black car and approach the front corner of it. Once you are next to the black car's front, and you can look down and see that you're standing approximately at the intersection of the cracks of the floor making up the garage floor, you're done.
