5-24 Instruments and Controls
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.
If your vehicle is low on fuel, the
FUEL LEVEL LOW message
displays. See Fuel System
Messages on page 5 29 for more
information.
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 this display to
zero, press and hold the set/reset
button.
Instantaneous Economy
Press the trip/fuel button until INST
ECONOMY displays. This display
shows the current fuel economy at a
particular moment and will change
frequently as driving conditions
change. This display shows the
instantaneous fuel economy in miles
per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike
average economy, this screen
cannot be reset.
Average Speed
Press the trip/fuel button until
AVERAGE SPEED displays. This
display shows the average speed of
the vehicle in miles per hour (mph)
or kilometers per hour (km/h). This
average is calculated based on the
various vehicle speeds recorded

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.
