1998 Ls 400 Security Feature?

[Xkalaba]

Hey all, something happened to me yesterday that scared me. I opened my car with the key (turning the key twice to the right). All of a sudden all the windows came down including the sunroof? I tried to let them back up, but they would not respond. Out of panic, I turned the car off and all systems were functional again? Is this a security issue and is this a concern. Please help (it’s cold now and I would not want to drive around like that.

On my old Merc., holding the key in the locked position CLOSED all the windows and roof.

My'94 LS doesn't do this, maybe the '98 has a feature to open or close all.

Check your USA site someone will know!!

It's a Key function! Read your Owners Manual....as I have, having only just got my Ser 4 Ls 400!

It says that you can leave the windows down and the key will close them. Says just hold the 'unlock' button until the windows...open

Press the Lock button (hold it) to reverse.

Give it a try? (I haven't....yet!
