What does the TPMS warning light mean?

What exactly does it mean when my TPMS warning light comes on?

If the TPMS warning light comes ON and flashes ON for one second and OFF for three seconds, this indicates a malfunction with the vehicle’s TPMS system.

If the TPMS warning light comes ON and stays ON, take caution. This means that one or more of your tires may have a low-pressure condition. You should carefully slow the vehicle and park in a safe and secure place. You should then inspect all of your tires and check the air pressure. The correct air pressure for your vehicle can be found on the placard, usually located on the inside door panel.

Tires should be inflated to the vehicle manufacturer’s recommendation as found on the vehicle tire information door placard. The vehicle placard is normally located on the inside door panel or door itself. In many cases the specified tire pressure can also be found in the vehicle owner’s manual. The pressure indicated on the sidewall of the tire should not be your guide, as that is the maximum inflation pressure for the tire itself, not for the tire when used on your specific vehicle.
