Fuel econ (average fuel economy)
Select this function to display your
average fuel economy in miles/gallon
or liters/100 km.
If you calculate your average fuel
economy by dividing gallons of fuel
used by 100 miles traveled
(kilometers traveled by liters used),
your figure may be different than
displayed for the following reasons:
•
your vehicle was not perfectly level during fill-up
•
differences in the automatic shut-off points on the fuel pumps at
service stations
•
variations in top-off procedure from one fill-up to another
•
rounding of the displayed values to the nearest 0.1 gallon (liter)
Checking your highway fuel economy using the electronic
message center display
The following procedure will allow you to accurately monitor your actual
highway fuel economy. Since this procedure requires the vehicle speed
control system to be set to highway speeds, it must be run only on
suitable roadways where long distance speed control can be safely
maintained.
You may notice gradual improvement in fuel economy over the course of
your vehicle’s break-in period (approximately 1 000 miles [1 600
kilometers]).
1. Set the speed control. Refer to
Speed control
in this chapter.
