3 Answers
The method to reset the tire pressure light on a 2007 LaCrosse is: Open the front right door, remove the side panel of the dashboard, locate a red button, start the engine and press the red button. The tire pressure light will flash and then reset. The 2007 LaCrosse is a mid-size sedan with body dimensions of 4998mm in length, 1851mm in width, and 1461mm in height, with a wheelbase of 2807mm. It has a fuel tank capacity of 72 liters and a curb weight of 1560kg. The 2007 LaCrosse features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 2.4L naturally aspirated engine, producing a maximum horsepower of 168PS, a maximum power of 125kW, and a maximum torque of 225Nm, paired with a 4-speed automatic transmission.
To be honest, resetting the tire pressure light on the old LaCrosse requires some skill. I just finished dealing with my 2007 model. First, make sure all four tires have the correct pressure. Turn the key to the ON position but don't start the engine. Press and hold the SET button on the center console while watching the tire pressure light on the dashboard. After about four to five seconds, it will start flashing. Keep holding the button until the light turns solid, then release it. Finally, turn off the ignition completely and restart the car. Remember, you need to hold it long enough—if it's too short, the system won't recognize it. After resetting, it's best to drive for a while to let the system calibrate itself. This old car reacts a bit slow but is quite steady.
I once encountered this issue when repairing my relative's 2007 LaCrosse. For this generation of vehicles, the TPMS reset button is located on the left side of the steering column with an exclamation mark symbol - many people spend a long time searching for it. Here's the procedure: First turn the ignition to position II (where all dashboard lights illuminate but the engine doesn't start), then press and hold that TPMS reset button for 4-5 seconds. Key point: You'll first see the tire pressure warning light on the dashboard start blinking - at this moment you must keep holding the button without releasing until the light stays steadily illuminated, which indicates successful reset. Pro tip: If performing this in winter, it's better to wait until the car has been driven and warmed up for more accurate tire pressure readings. After resetting, the system takes up to 48 hours to complete its automatic learning process - don't panic if the light doesn't turn off immediately after a few short trips.
