(Trip/Fuel):Press this button to scroll
through the following menu items:
Odometer
Press the trip/fuel button until ODOMETER
displays. This display shows the distance the
vehicle has been driven in either miles (mi)
or kilometers (km). Pressing the trip odometer
reset stem will also display the odometer.
To switch between English and metric
measurements, see “Units” later in this section.
Trip Odometer
Press the trip/fuel button until TRIP displays. This
display shows the current distance traveled in either
miles (mi) or kilometers (km) since the last reset for
the trip odometer. Pressing the trip odometer reset
stem will also display the trip odometer.
The trip odometer can be reset to zero by pressing
the set/reset button while the trip odometer is
displayed. You can also reset the trip odometer
while it is displayed by pressing and holding
the trip odometer reset stem.
269

The trip odometer has a feature called the
retro-active reset. This can be used to set the trip
odometer to the number of miles (kilometers)
driven since the ignition was last turned on. This
can be used if the trip odometer is not reset at the
beginning of the trip.
To use the retro-active reset feature, press and
hold the set/reset button for at least four seconds.
The trip odometer will display the number of
miles (mi) or kilometers (km) driven since the
ignition was last turned on and the vehicle
was moving. Once the vehicle begins moving, the
trip odometer will accumulate mileage. For
example, if the vehicle was driven 5 miles (8 km)
before it is started again, and then the retro-active
reset feature is activated, the display will show
5 miles (8 km). As the vehicle begins moving, the
display will then increase to 5.1 miles (8.2 km),
5.2 miles (8.4 km), etc.
If the retro-active reset feature is activated after
the vehicle is started, but before it begins moving,
the display will show the number of miles (mi)
or kilometers (km) that were driven during the last
ignition cycle.Fuel Range
Press the trip/fuel button until FUEL RANGE
displays. This display shows the approximate
number of remaining miles (mi) or kilometers (km)
the vehicle can be driven without refueling. The
display will show LOW if the fuel level is low.
The fuel range estimate is based on an average of
the vehicle’s fuel economy over recent driving
history and the amount of fuel remaining in the fuel
tank. This estimate will change if driving
conditions change. For example, if driving in traffic
and making frequent stops, this display may
read one number, but if the vehicle is driven on a
freeway, the number may change even though
the same amount of fuel is in the fuel tank. This is
because different driving conditions produce
different fuel economies. Generally, freeway
driving produces better fuel economy than city
driving. Fuel range cannot be reset.
270

Average Economy
Press the trip/fuel button until AVG ECONOMY
displays. This display shows the approximate
average miles per gallon (mpg) or liters per
100 kilometers (L/100 km). This number is
calculated based on the number of mpg (L/100 km)
recorded since the last time this menu item was
reset. To reset AVG ECONOMY, press and
hold the set/reset button.
Fuel Used
Press the trip/fuel button until FUEL USED
displays. This display shows the number of
gallons (gal) or liters (L) of fuel used since the last
reset of this menu item. To reset the fuel used
information, press and hold the set/reset button
while FUEL USED is displayed.
Timer
Press the trip/fuel button until TIMER displays.
This display can be used as a timer.To start the timer, press the set/reset button while
TIMER is displayed. The display will show the
amount of time that has passed since the timer was
last reset, not including time the ignition is off. Time
will continue to be counted as long as the ignition is
on, even if another display is being shown on the
DIC. The timer will record up to 99 hours,
59 minutes and 59 seconds (99:59:59) after which
the display will return to zero.
To stop the timer, press the set/reset button briey
while TIMER is displayed.
To reset the timer to zero, press and hold the
set/reset button while TIMER is displayed.
Transmission Temperature
Press the trip/fuel button until TRANS TEMP
displays. This display shows the temperature of
the automatic transmission uid in either degrees
Fahrenheit (°F) or degrees Celsius (°C).
271

Instantaneous Economy and Active Fuel
Management™ Indicator
If your vehicle has this display, press the trip/fuel
button until INST ECONOMY V8 MODE
displays. This display shows the current fuel
economy at a particular moment and will change
frequently as driving conditions change. This
display shows the instantaneous fuel economy in
miles per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike average
economy, this screen cannot be reset.
An Active Fuel Management™ indicator will
display on the right side of the DIC, while
INST ECONOMY displays on the left side. Active
Fuel Management™ allows the engine to
operate on either four or eight cylinders, depending
on your driving demands. When Active Fuel
Management™ is active, V4 MODE will display on
