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” underDIC Warnings and Messages
on page 244. You should change the oil as
soon as you can. SeeEngine 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. SeeScheduled Maintenance
on page 502for 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.

If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi)
or kilometers (km) that were driven during the
last ignition cycle.
RANGE
Press the trip/fuel button until RANGE displays.
This display shows the approximate number
of remaining miles (mi) or kilometers (km) the
vehicle can be driven without refueling. The
display will show LOW if the fuel level is low.
The fuel range estimate is based on an average
of the vehicle’s fuel economy over recent
driving history and the amount of fuel remaining
in the fuel tank. This estimate will change if driving
conditions change. For example, if driving in
traffic and making frequent stops, this display
may read one number, but if the vehicle is driven
on a freeway, the number may change even
though the same amount of fuel is in the fuel
tank. This is because different driving conditions
produce different fuel economies. Generally,
freeway driving produces better fuel economy
than city driving. Fuel range cannot be reset.
AVG (Average) ECONOMY
Press the trip/fuel button until AVG ECONOMY
displays. This display shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and
hold the set/reset button.
TIMER
Press the trip/fuel button until TIMER displays.
This display can be used as a timer.
To start the timer, press the set/reset button while
TIMER is displayed. The display will show the
amount of time that has passed since the timer
was last reset, not including time the ignition is off.
Time will continue to be counted as long as the
ignition is on, even if another display is being shown
on the DIC. The timer will record up to 99 hours,
59 minutes and 59 seconds (99:59:59) after which
the display will return to zero.
To stop the timer, press the set/reset button briey
while TIMER is displayed.
To reset the timer to zero, press and hold the
set/reset button while TIMER is displayed.
