How to reset the tire pressure monitoring system on the Buick Excelle?
4 Answers
The method to reset the tire pressure monitoring system on the Buick Excelle is as follows: 1. Press the menu button on the turn signal lever to switch the small screen on the instrument panel to the vehicle information column; 2. Rotate the up and down selection buttons to enter the tire pressure information column; 3. Press and hold the set/clr function key until the display asks whether to perform tire pressure learning, select 'Yes' and press the menu button to confirm; 4. After selection, the instrument will display 'Tire pressure learning in progress', the horn will sound twice, and the left front turn signal will light up. Use a tool to press the valve core to deflate the left front tire until the horn sounds once, the left turn signal turns off, and the right turn signal lights up, indicating the left front tire calibration is complete; 5. After the left front calibration is complete, deflate the right front tire until the horn sounds once, indicating the right front tire calibration is complete; 6. Follow this method to complete the calibration of the left and right rear tires; 7. Adjust the tire pressure according to the vehicle standard and install the valve cap; 8. Start the vehicle and observe whether the instrument lights display normally. If no warning lights flash, the vehicle's tire pressure monitoring system reset is complete.
Last year when I was driving my Excelle, I also researched this. The reset method is actually quite simple. With the car powered on but not started, locate the exclamation mark button with brackets below the left side of the instrument cluster (on some model years it's in the steering wheel left area), press and hold for 5 seconds until you hear a beep from the dashboard. The TPMS warning light will blink three times then go off. Two important reminders: 1) Before operation, you must adjust all four tires' cold pressure to the standard 2.4bar; 2) If you've repaired a tire but didn't reset, the TPMS light might suddenly come on during highway driving and give you a scare. After resetting, it's recommended to drive 2km to let the system relearn. Newer models with center displays can even show real-time tire pressure data in the vehicle settings menu - super practical feature.
I know the tire pressure monitoring reset like the back of my hand! For the Buick Excelle models after 2018, it's super intuitive: just start the vehicle, swipe to the 'Vehicle Settings' menu on the center console screen, tap the 'Tire Pressure Monitoring System' option, and finally confirm 'Relearn'. However, the older models with physical buttons are more common: turn the key to the ON position without starting the engine, then hold down the tire pressure reset button near the glove box (it's a semicircle with an arrow icon), and wait for the 'ding' prompt sound from the dashboard to complete the process. The key is to ensure the tire pressure is adjusted correctly when the tires are cold. It's recommended to check monthly during seasons with large temperature differences between winter and summer. Last time, my neighbor had a false alarm because the tire pressure was off by 0.3 bar.
The reset operation consists of four steps: 1. Inflate the tires to the pressure value marked on the door frame label when the engine is cold; 2. Turn on the ignition but do not start the engine; 3. Press and hold the tire pressure reset button; 4. Release the button upon hearing the confirmation sound. As someone who has driven three generations of Excelle, I noticed a detail: models before 2018 required driving a few kilometers after reset to update the data, while newer models with electronic power steering systems take effect immediately after reset. Also, don't rush to turn off the power—wait until the tire pressure warning symbol on the dashboard completely disappears for a successful reset.
