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.
The DTE 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) miles to empty.
DTE 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.
AVERAGE FUEL 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 RESET button (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.

FUEL ECONOMY MPG (L/km)
This displays instantaneous 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.
FUEL USED XX.X GAL (L)
This displays the fuel used since last reset. The information displayed
will be in gallons or liters, depending on English/Metric mode state.
DRIVE TIME
Timer displays the trip elapsed drive time.
To operate, do the following:
1. Press and release RESET in order to start the timer.
2. Press and release RESET to pause the timer.
3. Press and hold RESET until the timer resets.

•Adding certain accessories to your vehicle (for example; bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA fuel economy estimates
Every new vehicle should have a sticker on the window called the
Monroney Label which contains EPA fuel economy estimates. Contact
your authorized dealer if the Monroney Label is not supplied with your
vehicle. The EPA fuel economy estimates should be your guide for the
fuel economy comparisons with other vehicles. Your fuel economy may
vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
•Have the items listed inscheduled maintenance information
performed according to the specified schedule.
The scheduled maintenance items listed inscheduled maintenance
informationare essential to the life and performance of your vehicle
and to its emissions system.
