This display shows the
instantaneous fuel economy in
liters per 100 kilometers (L/100 km)
or miles per gallon (mpg). Unlike
average economy, this screen
cannot be reset.
An Active Fuel Management
indicator will display on the right
side of the DIC, while INST ECON
displays on the left side. Active
Fuel Management allows the
engine to operate on either four or
eight cylinders, depending on your
driving demands. When Active
Fuel Management is active, V4 will
display on the DIC. When Active
Fuel Management is inactive,
V8 will display. See Active Fuel
Management

Oil Life
Press the vehicle information
button 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 Engine Oil Messages on
page 541. You should change the
oil as soon as you can. See Engine
Oil on page 107. 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 112 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 1010.
