I'm sure it can be done. I turned off the warning chime in the Matrix a month ago. Now the warning light just blinks and there's silence. A Lexus is a Toyota, so if I can turn it off on the Matrix I'm sure there's a sequence to change it on the new IS without taking it to the dealer.
The problem is the Matrix insructions requires turning the key in the ignition. Since new IS has a "start" button I doubt it will work the same. Some Lexus tech must know what to do. We just have to keep searching or experiment.
Here's the Matrix instructions just so you get an idea...
1. turn the key to the ON position, foot off the brake
2. cycle the odometer with the trip reset button until the ODO is displayed (not trip A or B)
3. turn the ignition to the LOCK (OFF) position
4. unbuckle the driver's seatbelt if it was buckled.
5. turn the key to the ON position. when the dash lights have come on, press and hold the trip reset button and count a slow 12 seconds. (editor's note, hold it more like 30 sec)
6. while still holding the trip reset button, buckle the driver's side seatbelt.
7. the odometer display should read "b ON" or "b OFF". toggle the beep OFF with the trip reset.
8. the process should be completed when you unbuckle or turn the key off.
...minutes, after i put my daughter to bed. i hope it works. i was in a mood today where i just wanted some queit. i was under the seat pulling plugs when i got home! as i havent tried it just yet, i have to believe that this will work since there is a way to do it on another toyota model without pulling plugs, fuses or cutting wires...be back tomorrow with my update!

i just tried it in my GS, and it worked!!!!!!! THANKS FOR POSTING THE SOLUTION
the only difference in the GS is that there is a separate "RESET" button to the right of the ODO/TRIP button. at first i kept doing the reset button and it didn't work. You just hold the ODO/TRIP button instead.
1. turn the key to the ON position which means pressing the start button twice on the new IS since it doesn't has the key, foot off the brake
2. Press the trip reset button couple of times until the ODO is displayed (not trip A or B)
3. turn the ignition to the LOCK (OFF) position
4. unbuckle the driver's seatbelt if it was buckled.
5. turn the key to the ON position again press the start button twice. when the dash lights comes on, press and hold the trip reset button and count a slow 12 seconds. (editor's note, hold it more like 30 sec)
6. while still holding the trip reset button, buckle the driver's side seatbelt.
7.and the odometer display should read "b ON" or "b OFF". toggle the beep OFF with the trip reset.
8. the process should be completed when you unbuckle or turn the key off.

This is actually posted in the Lexus IS250/350 Repair Manual on page BE-195:
Buzzer Reminder Cancel Mode Setting
1) Set the LCD on the combination meter to the ODO display.
2) Press and hold the TRIP meter reset knob for ten seconds or more within six seconds of turning the power source to IG-ON. Fastening the driver's seat belt or front passenger seat belt while holding the knob cancels the buzzer reminder.
If the driver seat belt is fastened: the system changes to the front passenger buzzer reminder cancel mode.
If the front passenger seat belt is fastened: the sytem changes to the front passenger buzzer reminder cancel mode.
3) When this occurs, the LCD displays "b-oFF". The buzzer reminder can be switched between ON and OFF each time the TRIP meter reset knob is pressed. The LCD displays "b-on" or "b-oFF" according to the buzzer reminder ON/OFF status. The display changes to the ODO or TRIP meter if the knob is not pressed for ten seconds.
4) Performing steps 1) and 2) again when the buzzer reminder is off exits cancel mode.
5) The cancel mode will also exit when the battery or combination meter connector is disconnected or reconnected.
