the same as the average fuel economy display. The running average fuel
economy is re-initialized to a factory default value if the battery is
disconnected.
Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or
liters/100 km.
If you calculate your average fuel
economy by dividing distance traveled by gallons of fuel used (liters of
fuel used by 100 kilometers traveled), 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)
To determine your average highway fuel economy, do the following:
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET control (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
For more information refer toEssentials of good fuel economyin the
Maintenance and Specificationschapter.
Instantaneous fuel economy (IFE)
Select this function from the INFO
menu to display your instantaneous
fuel economy. This will display your
fuel economy as a bar graph ranging
from
poor economy to
excellent economy.
Your vehicle must be moving to calculate instantaneous fuel economy.
When your vehicle is not moving, this function shows
, one or no bars
illuminated. Instantaneous fuel economy cannot be reset.

•DO NOT use a device that would hold the fuel pump handle in the fill
position.
Easy Fuel™ “no cap” fuel system
Your fuel tank is equipped with an Easy Fuel™ “no cap” fuel filler
system. This allows you to simply open the fuel filler door and insert the
fuel filler nozzle into the fuel system. The Easy Fuel™ system is
self-sealing and protected against dust, dirt, water and snow/ice.
When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel filler door.
3. Slowly insert the fuel filler nozzle fully into the fuel system. Pump fuel
as normal.
4. After you are done pumping fuel, slowly remove the fuel filler
nozzle—allow about five seconds after pumping fuel before removing the
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank
and not spill onto the vehicle.
Note:A fuel spillage concern may occur if overfilling the fuel tank. Do
not overfill the tank to the point that the fuel is able to bypass the fuel
filler nozzle. The overfilled fuel may run down the drain located below
and in front of the fuel filler door.
If the Check Fuel Fill Inlet lamp or Check Fuel Fill Inlet message comes
on, the fuel fill inlet may not have properly closed. The inlet may have
stuck open or debris may be preventing the inlet from fully closing. At
the next opportunity, safely pull off the road, turn off the engine, open
the fuel filler door and remove any visible debris from the fuel fill
opening. Insert either the fuel fill nozzle or the fuel fill funnel (see
Refilling with a portable fuel containerfor funnel location) provided
with the vehicle several times to dislodge any debris and/or allow the
inlet to close properly. If this action corrects the problem, the Check
Fuel Fill Inlet lamp or Check Fuel Fill Inlet message may not reset
immediately. It may take several driving cycles for the Check Fuel Fill
Inlet lamp or Check Fuel Fill Inlet message to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by city/highway driving. Continuing to drive with the Check
Fuel Fill Inlet lamp or Check Fuel Fill Inlet message on may cause the
Service Engine Soon lamp to turn on as well.
