How to reset the tire pressure light on a 2017 low-end Buick Excelle?

[CalebFitz]

Press the "MENU" button on the turn signal lever to switch the small screen on the dashboard to the "Vehicle Information" section. Rotate the up and down selection buttons on the turn signal lever to find the tire pressure information section. Press and hold (long press) the "SET/CLR" function key at the head of the turn signal lever. Perform tire deflation in the following order: front left — front right — rear right — rear left. Unscrew the valve cap and use a small tool like a key to press the small pin inside the valve core. When the right turn signal lights up, repeat the above method to continue deflating the front right tire until the horn beeps once and the right turn signal turns off. Observe the tire pressure condition of each tire. The tire pressure will be lower than the normal value, so you need to inflate the tires in order to bring the tire pressure back to the normal range.
