What year corolla you have? If I press the button in my 2013 it will deactivate traction control. As soon as I hit 40 km/h (I think) it turns back on. If I press and hold it, I think for 5 seconds, it will deactivate both Traction control and stability control, trac light will light on left side of IC and stability control light will be on right side of IC, and will stay off at any speed until I press the button again.
