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 "Low Fuel Level
Message" 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
miles per hour (mph) or kilometers per hour (km/h).

speeds recorded since the last reset of this menu item.
