Your vehicle's charging system regulates voltage
based on the state of the battery. The battery
voltage may fluctuate when viewing this
information on the DIC. This is normal.
If there is a problem with the battery charging
system, a DIC message will display. See
DIC Warnings and Messages on page 230 for
more information.
Oil Life
Press the information 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 411. 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 509 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 414. The display will show
100% when the system is reset.
