Hello. I wanna help. I tried, the methon on my Rx400h, but doesn't work. I turned the car(don'T start engine), set display to ODO, turn off the ignition, wait 5 sec, turn on, press and hold ODO button for 12 sec, turn on the seat belt, and the display shows "Seat Belt buzzer: On", I pressed the ODO button to change OFF, and wait to disappear the label. Turn off the ignition, and turn on, and again shows the "warning" on screen. What do I do wrong? Thanks!
