OIL LIFE
To access this display, the vehicle must be in
PARK (P). Press the trip odometer reset stem until
OIL LIFE REMAINING displays. This display
shows an estimate of the oil's remaining useful
life. If you see 99% OIL LIFE REMAINING on the
display, that means 99% of the current oil life
remains. The engine oil life system will alert you
to change the oil on a schedule consistent
with your driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on
the display. See "CHANGE ENGINE OIL
SOON" under DIC Warnings and Messages
on page 244. You should change the oil as
soon as you can. See Engine Oil on page 397.
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 502 for more information.
Remember, you must reset the OIL LIFE
display yourself after each oil change. It will not
reset itself. Also, be careful not to reset the
OIL LIFE display 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 400.
