Method to check tire pressure on Buick Excelle (not available for base models): 1. Press the "MENU" button on the turn signal lever to switch the small screen on the instrument panel to the "Vehicle Information Menu." 2. The Vehicle Information Menu has only two pages: overspeed alarm and tire pressure monitoring. 3. If the overspeed alarm is displayed, rotate the knob at the top of the left lever to switch to the tire pressure monitoring information, where you can view the tire pressure of all four wheels. Buick Excelle tire pressure monitoring reset method: 1. First, park the vehicle, engage the handbrake, and operate with the vehicle powered on. 2. Press the MENU button on the turn signal lever to switch the small screen on the instrument panel to the Vehicle Information section. 3. Rotate the up and down selection buttons on the turn signal lever to find the tire pressure information section. 4. Press and hold (long press) the SET/CLR function button at the head of the turn signal lever until the display shows whether to perform tire pressure learning, then select "Yes." 5. After selection, the horn will sound twice to confirm the start of tire pressure learning. 6. At this point, the left front turn signal will light up, and then proceed to deflate the tire. The order is: left front, right front, right rear, left rear. Unscrew the valve cap to release air from the tire. When the horn sounds once and the current tire's turn signal turns off while the right turn signal lights up, you can release the valve. 7. With the right turn signal lit, repeat the above method to continue deflating the right front tire until the horn sounds once and the right turn signal turns off, then stop deflating. 8. Proceed in order, observing the tire pressure status of each tire on the instrument panel. The tire pressure will be lower than normal, so you need to inflate the tires in sequence to bring the pressure back to the normal range, generally between 2.3~2.5. This completes the tire pressure reset.
