I have just purchased a Stilo 1600 (2004) and I've noticed something unusual.
When I turn the key to open the door on the drivers side, both driver and passenger front windows open.?
I don't believe that this is normal, at least I don't think so.
Anyone know why this could be happening and how to I go about sorting it?

If you hold the key in the unlock position for more than 2 seconds, the windows and sunroof (if fitted) are supposed to open. If you hold the key in the lock position for more than 2 seconds, they should close.

All UK supplied Stilos came with remote locking so you should have 2 remote keys. Same thing happens with the windows if you use the remote buttons to unlock and lock the car. Hold the unlock button on the remote for more than 2 seconds and the windows should go down. Hold the unlock button for more than 2 seconds and they should go up.

There's a thread about Stilo hidden features here: https://www.fiatforum.com/stilo/82058-stilo-hidden-features.html

thanks very much and thanks for the link
