1. Inflate Tires to Proper Pressure: Check the sticker on your driver's side doorjamb or your owner's manual for the recommended tire pressure. Inflate all four tires to the correct pressure, including the spare.
2. Drive the Vehicle: Drive the vehicle at a speed of at least 20 mph (32 km/h) for approximately 10-20 minutes. This allows the TPMS sensors to send data to the car's computer.
3. Check the Light: After driving, the tire pressure monitoring system light should turn off if the tires are properly inflated and there are no other issues with the sensors.
If the light remains on after driving, there could be several reasons:
* Low Tire Pressure: Double-check your tire pressures. Even a slight underinflation can trigger the light.
* Faulty Sensor: One or more of your TPMS sensors may be malfunctioning. This will require professional diagnosis and likely replacement of the faulty sensor(s).
* Other Issues: A problem with the TPMS module itself is also possible, but less likely.
If you've tried the above and the light persists, you'll need to:
* Consult your owner's manual: It might have specific instructions for your model year.
* Visit a tire shop or mechanic: They have the tools to check the tire pressure and diagnose any TPMS problems. They can also test and replace sensors if necessary.
There is no "reset" button in the traditional sense for the TPMS light on a 2007 Impala. The system self-resets after it detects proper inflation and sufficient driving time.
