 |
Smart Tire Pressure Monitoring System (TPMS) Warning LightThe TPMS warning light symbol indicates low tire pressure in one or more tires, often triggered by a 25% or more reduction in inflation. This can occur due to temperature changes, especially in fall and winter, or a single leaking tire. Check your tire pressure immediately and inflate to the recommended level. If the light remains on after inflation, inspect for leaks or sensor malfunctions. Ensure all tires, including the spare, are properly inflated to ensure safe driving. |
 |
