Tire Pressure Monitoring System

The Tire Pressure Monitoring System (TPMS) screens display tire pressure, temperature, and sensor battery status. See Fig.. Maintaining correct tire pressure increases fuel economy. Sustained high tire temperature can cause a tire to deteriorate, leading to tread separation and blowouts.

Fig. 1, Vehicle Operations: TPMS Axle Tire Pressure, Temperature, and Sensor Status

Tire pressure can be displayed in psi or bar units. Temperature can be displayed in °F or °C. Units of measure are set under Settings. Sensor battery status is displayed as a bar chart inside the outline of a battery.

The TPMS will change the color of the tire on the ICUC screen if the tire pressure or temperature is either too high or too low. See Fig.. It will also change the color of the sensor battery icon if the power levels are too low. Amber indicates a condition that may result in damage. Red indicates a condition that may pose a threat to the vehicle.

Tire pressure monitoring settings are part of the TPMS. Threshold temperatures and what triggers alerts can be set on this screen.
