Tire Pressure Monitor System (TPMS)
CAUTION:
The TPMS may not function properly if tire type and size are mixed. Make sure to use the same size and type of tire.
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.
