It is a inventory tracking label that allows entry of user-defined data (see attached specifications). It could be the shipping label for your car - Was your car shipped to you? The label seems to be applied backward. It is not needed for the operation of the LS430.

 

It's for the dealer. When you pull your car into the service bay they get all the vehicle's information automatically.

 

There is no such tape on my car and never has been.

 

 

I have something similar to what's shown in the picture, although mine is about half as long. (that's what she said).

It's also affixed to the inside of the windshield, slightly above the top edge of rear view mirror. I placed it there when I signed up for the 'unlimited carwash' club.

I pay $19.99 a month for an unlimited amount of automatic car washes with the soft bristles. It also scrubs the tires and sprays the undercarriage, etc. My post is NOT intended to have a debate on how bad or how damaging automatic car wash mechanisms are for the clearcoat/paint! There are a couple of toll-gate arms that have RFID readers in the bridge structure above. When I drive up, it communicates and the toll gate arm automatically raises. Where I live, 1 time through a carwash can cost anywhere from $9 to $20. I figure if I use the carwash 2x a month, it's worth it to me.

 

They apparently had an identical sticker in the IS forum. Check it out (and their time-wasting replies) here... https://www.clublexus.com/forums/is-...-mirror-4.html
