MI TRIP A and B: For information on the trip
odometers, see Trip Odometers on page 3-37 .
MPG AVG: If you select this item, the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km) is displayed. 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 the MPG AVG, press the CLR button located to
the right of the screen. The display will return to zero.
MPG INST: If you select this item, the current fuel
economy is displayed. This number reflects only the
fuel economy that the vehicle has right now and
will change frequently as driving conditions change.
Unlike average fuel economy, this menu item cannot
be reset.
GAL FUEL USED: If you select this item, the number
of gallons or liters of fuel used since the last reset of this
menu item is displayed.
To reset GAL FUEL USED, press the CLR button
located to the right of the screen. The display will
return to zero.
MILES 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.
3-60
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 Fuel Level Low
message will be displayed. See "Fuel Level Low" under
DIC Warnings and Messages on page 3-65 for more
information.
AVG MPH: If you select this item, the average speed
of the vehicle is displayed in miles per hour (mph)
or kilometers per hour (km/h). This average is calculated
based on the various vehicle speeds recorded since
the last reset of this menu item.
To reset AVG MPH, press the CLR button located to
the right of the screen. The display will return to zero.
TIMER: If you select this item, a timing feature is
displayed. The timer functions like a stopwatch in that
you can record the time it takes to travel from one point
to another.
To use the timer, you must first turn it on. To turn
on the timer, press the CLR button located to the
right of the screen once. The display will read
00:00:00 TIMER ON and begin counting.
