Distance to empty (DTE)
Selecting this function from the
INFO menu estimates 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. If you RESET this warning
message, this display and tone will return within 10 minutes.
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 reinitialized 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 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)
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 after setting the speed
control to get accurate highway fuel economy readings.
For more information refer toFuel Informationin theMaintenance
and Specificationschapter.

FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
The fuel pump shut-off switch is
located in the front passenger
footwell area in the right upper
corner.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition ON.
5. Wait a few seconds and return
the key to OFF.
6. Make another check for leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials
and any open flames before
refueling your vehicle.
•Always turn off the vehicle before
refueling.
•Automotive fuels can be harmful
or fatal if swallowed. Fuel such as gasoline is highly toxic and if
swallowed can cause death or permanent injury. If fuel is swallowed,
call a physician immediately, even if no symptoms are immediately
apparent. The toxic effects of fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking “Antabuse” or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.
The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.
