Respond to TPMS dashboard warnings promptly
4
Most cars from 2008 onward have a Tire Pressure Monitoring System that lights a dashboard icon (a tire cross-section with an exclamation mark) when any tire drops significantly below the recommended PSI. Treat the warning as a prompt to check all four tires with a gauge and inflate to spec.
How to Read the Light
- Steady light: At least one tire is significantly underinflated. Check and correct pressure as soon as possible.
- Flashing then steady: The TPMS sensor itself has malfunctioned. Have the system inspected at a shop.
Tips
- TPMS only warns about significant drops, not slight losses -- it does not replace monthly gauge checks
- After inflating, drive a short distance; the light should reset within a few minutes
- Battery-powered TPMS sensors typically last 5-10 years before needing replacement
