TPMS light

5 Episode Mentions

Too Afraid to Ask

TPMS is a sensor in each tire that tells you when the tire pressure is too low. If the light comes on, it means one or more tires need to be checked and possibly inflated.

Technical Definition

TPMS stands for Tire Pressure Monitoring System, a safety feature that alerts drivers when tire pressure drops below a certain threshold. The light indicates the system has detected low pressure, but it may not trigger until the tire is significantly underinflated.
