Reset a notice on the dashboard on 2001 Lexus LS430

I had a sign on the dashboard saying I need to replace my A/C filter which I consequently changed, but the notice still shows in my dashboard. How can I reset so that it does not anymore now

Hey, had the same problem.. went to Lexus Service center.. they did it for free.. don't remember exactly.. but they pressed some button on the A/C controller and it just restarted the system.
Just press and hold the AC OFF button and the dash will display the AC filter reset light.
