Indirect Tire Pressure Monitoring System (TPMS) (Select Vehicles)

What’s the Benefit?

The Tire Pressure Monitoring System6 (TPMS) helps enhance driver awareness of low tire pressure, allowing corrective steps to be taken in a timely manner.


The Feature:

In this system, the vehicle’s ABS wheel-speed sensors calculate air pressure based on wheel-rotation characteristics.

  • When the system detects that a tire’s pressure has dropped significantly below the recommended pressure, it alerts the driver by illuminating the TPMS indicator within the gauge cluster.
  • The instrument panel displays a flashing icon of a tire’s cross section with an exclamation point to alert the driver that one or more of the vehicle’s tires is significantly low.
  • Drivers should visually inspect the tires, then check and adjust their pressure when cold to the appropriate specification.
  • Note: Spare tires do not have TPMS.
