Here's the process:
1. Check your tire pressure: Use a reliable tire gauge to check the pressure in all four tires, including the spare. Refer to the sticker on your driver's side doorjamb for the recommended tire pressure. This is crucial; the light won't reset if the tires aren't properly inflated.
2. Inflate tires: Add air to any tires that are below the recommended pressure.
3. Drive the vehicle: Drive the Chrysler 300 for about 10-20 minutes at speeds above 20 mph. This allows the TPMS sensors to transmit the new pressure readings to the vehicle's computer.
4. Check the light: After driving, turn off the car and then turn it back on. The TPMS warning light should turn off. If it doesn't, repeat steps 1-3, ensuring that the tires are properly inflated.
If the light remains on after properly inflating tires and driving:
* Check for TPMS sensor issues: A malfunctioning sensor is a common cause. You might need to have your tires checked by a mechanic to diagnose any sensor problems. A faulty sensor may need replacement.
* Check for other issues: There might be a problem with the TPMS system itself, requiring a diagnostic scan by a mechanic.
There is no manual reset button on the 2007 Chrysler 300's dashboard for the TPMS. The system is designed to self-reset once the correct tire pressure is detected.
