Instead of directly measuring the pressure in each tire, the TPMS on this vehicle monitors and compares the rolling radius and rotational characteristics of each wheel and tire while you are driving to determine if one or more tires are significantly under-inflated. This will cause the low tire pressure/TPMS indicator to come on and a message to appear on the display.

Reasons for the indicator to come on or blink

If your vehicle's tire pressure becomes significantly low, If there is a problem with the TPMS or the compact spare tire is installed, the indicator blinks for about one minute, and then stays on.
