Here's the proper procedure:
1. Inflate Tires: Check the sticker on your driver's side doorjamb or your owner's manual for the recommended tire pressure for your vehicle. Inflate each tire to the specified pressure using a reliable tire pressure gauge. Don't just rely on the gas station air compressor's gauge.
2. Drive the Vehicle: Drive your Chrysler 300C for 10-15 minutes at a speed of at least 20 mph (32 km/h). This allows the TPMS sensors to recalibrate.
3. Check the Warning Light: After driving, the low tire pressure warning light should turn off. If it doesn't, there might be a problem with one or more of your TPMS sensors, a faulty sensor, or a more serious tire pressure issue.
If the light remains on after following these steps:
* Check Tire Pressure Again: Double-check your tire pressure to ensure it's accurate. A slight underinflation might still trigger the light.
* Check for Damaged Sensors: Sometimes a sensor can become damaged or malfunction. A tire shop can diagnose this issue.
* Consult Your Owner's Manual: Your owner's manual might provide specific instructions for your vehicle's TPMS system.
* Visit a Mechanic or Tire Shop: If you've tried everything and the light persists, take your Chrysler 300C to a qualified mechanic or tire shop for diagnosis and repair. They have the tools to check the TPMS sensors and identify any problems.
Important Note: Ignoring a low tire pressure warning light is dangerous. Underinflated tires can lead to poor handling, reduced fuel economy, and increased risk of a blowout. Always address low tire pressure promptly.
