What is the cutout on the lower "passanger" side of the front bumper for? See the picture posted on the ES350 vs. M35 thread. It's about 12 inches or so in from the passanger side of the car on the front bumper; on the bumper below the inner most corner of the headlight.

I was thinking it could be for that cruise-radar option (or whatever they call it) where they put a front sensor to maintain the distance with a car infront of you and change your cruise speed if you get too close? That is the only explanation I have...

I believe if you pry open the squares, you'll find nuts or bolts that tie the bumper to the car frame. I saw a new GS330 AWD on the road a few days ago with TWO square "holes" like that. That car also happen to have the parking assist round sensors, so the entire bumper looks pretty screwed up with round and square indents. I don't know what the Lexus designer is thinking...

I believe BMW and others have similar panels on the body that popout to reveal a hook that can be used for towing or pulling the car. But I have no idea, just a thought.

The square cap covers a rather substantial threaded hole for a towing eyelet. This is for briefly moving the car (such as if it's stuck in the mud) and should never be used for for towing any distance at all.

It has nothing to do with the dynamic radar cruise control or the intuitive parking assistant.

Our sales guy said it was for a threaded eyelet that is used as a tie down during shipping.

It should be the hole for the towing eyelet. Just pop the cover, screw in the eyelet and have whoever's towing you out, pull you out. As dreyfus said, it should be used only in emergencies (e.g. pulling you out of a snowbank)

its for the towing eyelet.
