How to reset the tire pressure light on a 2009 Enclave?
3 Answers
Adjust the tire pressure to the standard level, turn on the ignition, and hold the button until a yellow light appears on the dashboard, then wait for the light to turn off. There is a button in front of the gear shift that looks like the tire pressure monitoring light. Press and hold this button to bring up the menu, then find and save the tire pressure monitoring setting.
I just helped a friend reset the tire pressure warning light on an old Enclave last week. For this vehicle, resetting the light involves a few steps: First, ensure all four tires are inflated to the recommended cold pressure (usually listed on the label inside the driver's side B-pillar). Turn the ignition to the ON position using the mechanical key without starting the engine. Then, simultaneously press and hold the two arrow buttons below the instrument cluster for about 5 seconds—the TPMS light will blink a few times before turning off. If the light stubbornly remains on, it might indicate a depleted sensor battery in one of the wheels. After all, it's a 2009 model, so rubber component aging is common, and weak batteries can also trigger false alarms.
Resetting the old Buick's tire pressure light requires a little trick. After inflating the tires to the value marked on the door label, sit in the car without pressing the brake and hold the start button to power on. Here's the key: use your left ring finger to press and hold the trip reset button, then quickly press the button on top of the light control stalk twice with your right hand. Watch the dashboard carefully—if the warning light flashes three times and then turns off, you've succeeded. If it doesn't work, consider whether the sensor signal is lost, especially in older cars with modified rims, as they are prone to this issue.
