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.

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 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 such as threshold temperatures can be set on the TPMS screen.
