Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition is
in ON.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything is wrong with the fuel gage:

At the gas station the gas pump shuts off before the
gage reads full.

The gage may change when you turn, stop quickly or
accelerate quickly.

It takes a little more or less fuel to fill the tank than
the gage indicated. For example, the gage may have
indicated that the tank was half full, but it actually
took a little more or less than half the tank's capacity
to fill the tank.

description of each menu item:
BLANK LINE/Blank Display: If you select this item,
nothing is displayed at the top of the screen.
OUTSIDE TEMP/Outside Temperature: If you select
this item, the current outside temperature is displayed at
the top of the screen. It will be in either degrees
Fahrenheit or degrees Celsius depending upon whether

listed previously in this section.
MPG AVG/Average Fuel Economy: If you select this

kilometers per liter (km/L) is displayed. This number is
calculated based on the number of mpg (km/L) recorded
since the last time this menu item was reset.

button to the right of the screen. The display will return

MILES RANGE/Fuel Range: If you select this item,
the approximate number of remaining miles or
kilometers you can drive without refueling is displayed.
This estimate is based on the current driving conditions
and will change if the driving conditions change. For
example, if you are driving in traffic making frequent
stops, the display may read one number, but if you enter
the freeway, the number may change even though you
still have the same amount of gas in the gas 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 Low Fuel Level
message will be displayed. See ªLow Fuel Level
Messageº in the Index for more information.
AVG MPH/Average Vehicle Speed: If you select this
item, the average speed of the vehicle is displayed in
