Extra parts? (Or where do these plugs go)

[jah]

Picked up a Red Hatch a week ago, this morning I washed it, found two rubber grommets in the passenger glove compartment. They are in a small clear bag marked in 4 different languages, the english one reads:
"IMPORTANT
TO PRE-DELIVERY INSPECTOR:
INSERT THESE RUBBER PLUGS INTO THE HOLES OF THE CENTER FLOOR SIDE MEMBER EXTENSIONS."

I am concerned that a pair of small holes are open to the elements because of these plugs not being installed. I intend to talk to the dealer when I get a chance to go in person, but does anybody know where these plugs go? Or does anybody have a Toyota service email address they have had response's too?

Later
