ENG HRS
Registers the accumulated time the engine has been running.
MILES (km) TO E
This displays an estimate of approximately how far you can drive with
the fuel remaining in your tank under normal driving conditions.
Remember to turn the ignition off when refueling to allow this feature to
correctly detect the added fuel.
This function will display LOW FUEL LEVEL when you have
approximately 50 miles (80 km), to empty. Press RESET to clear this
warning message. It will return at approximately 25 miles (40 km),
10 miles (16 km) and 0 miles (0 km) to empty.
The distance to empty is calculated using a running average fuel
economy, which is based on your recent driving history of 500 miles
(800 km). This value is not 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.
XX.X MPG (L/100km)
Average fuel economy displays 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)
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 SELECT/RESET button (press and hold the
SELECT/RESET button for two seconds in order to reset the function)
after setting the speed control to get accurate highway fuel economy
readings.
