Tire Pressure
This display shows the pressure for each tire in either
pounds per square inch (psi) or kilopascals (kPa). If the
tire pressure is normal, the value will display. If the tire
pressure is low or high, LOW or HIGH will appear on
the display with the value. SeeInflation - Tire Pressure
on page 5-64andDIC Warnings and Messages on
page 3-79for more information. Press the information
button to scroll through the following displays:

SOON message will appear on the display. Change
the oil as soon as possible. In addition to the engine oil
life system monitoring the oil life, additional maintenance
is recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
andEngine Oil on page 5-18.
After an oil change, reset the ENGINE OIL LIFE display.
To reset, seeEngine Oil Life System on page 5-21.
