Tire Pressure Press the gages button until FRONT TIRE PRESSURE displays. This mode shows the pressure for the front tires. To view the pressure for the rear tires, press the gages button again until REAR TIRE PRESSURE displays. The tire pressure will be shown in either pounds per square inch (psi) or kilopascals (kPa). If a low or high tire pressure condition is detected by the system while driving, a message advising you to check the pressure in a specific tire will appear in the display. See Inflation - Tire Pressure on page 409 and DIC Warnings and Messages on page 208 for more information. If the tire pressure display shows dashes instead of a value, there may be a problem with your vehicle. If this consistently occurs, see your dealer for service. Oil Life Press the gages button until OIL LIFE displays. This mode shows an estimate of the oil's remaining useful life. If you see OIL LIFE 99% on the display, that means 99% of the current oil life remains. The engine oil life system will alert you to change your oil on a schedule consistent with your driving conditions. When the remaining oil life is low, the CHANGE OIL SOON message will appear on the display. You should change your oil as soon as possible. See Engine Oil on page 353. In addition to the engine oil life system monitoring the oil life, additional maintenance is recommended in the Maintenance Schedule in this manual. See Scheduled Maintenance on page 462 for more information. Remember, you must reset the OIL LIFE yourself after each oil change. It will not reset itself. Also, be careful not to reset the OIL LIFE accidentally at any time other than when the oil has just been changed. It cannot be reset accurately until the next oil change. To reset the engine oil life system, see Engine Oil Life System on page 356. The display will show 100% when the system is reset. 204
