There is also a retroactive trip odometer function that
performs the following for each trip odometer:
If the vehicle’s speed has exceeded 3 mph (5 km/h)
during the current ignition cycle, this function will
set the trip odometer to the distance driven
during the current ignition cycle.
If the vehicle’s speed has not exceeded 3 mph
(5 km/h), this function will set the trip odometer
to the distance driven during the previous ignition
cycle plus the distance driven during the current
ignition cycle.
Press and hold the set/reset button on the uplevel
vehicle or the trip/odometer button on the base level
vehicle for three seconds, then release the button.
The retroactive trip odometer value will be set into the
currently displayed trip odometer.
Time Elapsed (Uplevel Only)
Press the trip/odometer button until TIME ELAPSED :00
displays. This mode is like a stopwatch, in that you
can clock the time it takes to get from one point
to another. Each of the elds for the hours, minutes,
and seconds are two numeric digits.Once TIME ELAPSED :00 is displayed, press the
set/reset button on the uplevel vehicle to start the timing
feature. Press the set/reset button again to stop it. If
you will be starting and stopping your vehicle, during a
trip for instance, the TIME ELAPSED feature will
automatically start timing where it left off when you last
stopped. To reset it, press and hold the set/reset
button for approximately 1.5 seconds. The display will
return to zero. Press the trip/odometer button to
exit from the TIME ELAPSED display.
Average Speed (Uplevel Only)
Press the trip/odometer button until AVERAGE SPEED
displays. This mode shows the average speed of the
vehicle in miles per hour (mph) or kilometers per hour
(km/h). This average is calculated based on the various
vehicle speed recorded since the last reset of this value.
To reset the value, press the trip/odometer button to
display AVERAGE SPEED, then press and hold the
set/reset button on the uplevel vehicle. The display will
return to zero.

Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays. This
mode shows the approximate number of remaining
miles or kilometers the vehicle can be driven without
refueling.
Fuel range is based on several factors, including distance
traveled, fuel used, fuel capacity, etc. This estimate will
change if driving conditions change. For example, if
driving in traffic and making frequent stops, this mode
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.
If your vehicle is low on fuel, FUEL RANGE LOW
will display followed by the LOW FUEL message. See
“LOW FUEL” underDIC Warnings and Messages
on page 3-59for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY displays.
This mode 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. The display will return to zero.
Instantaneous Fuel Economy
Press the fuel button until INST ECONOMY displays.
This mode shows the current fuel economy at a
particular moment and will change frequently as driving
conditions change. This mode shows the instantaneous
fuel economy in miles per gallon (mpg) or liters per
100 kilometers (L/100 km). Unlike average fuel
economy, this screen cannot be reset.

Gages Menu Items (Uplevel Only)
2
(Gages):Press this button to scroll through the
following menu items:
Battery
Press the gages button until BATTERY displays.
This mode shows the current battery voltage.
If there is a problem with the battery charging system,
a DIC message will display. SeeDIC Warnings and
Messages on page 3-59for more information.
Your vehicle’s charging system regulates voltage based
on the state of the battery. The battery voltage may
uctuate when viewing this information on the DIC.
This is normal.
Oil Life
Press the gages button until OIL LIFE displays. This
mode shows an estimate of the oil’s remaining useful
life. If you see OIL LIFE 99% on the display, that means
99% of the current oil life remains. The engine oil life
system will alert you to change your oil on a schedule
consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change your oil as soon as possible. SeeEngine Oil
on page 5-15. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4for
more information.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil
Life System on page 5-18. The display will show 100%
when the system is reset.

programmed to one setting on the vehicle and cannot be
programmed to a preferred setting for up to two drivers.
SeeDIC Vehicle Personalization on page 3-75for
additional information on personal programming.
Compass Zone
Under certain circumstances, such as during a long
distance cross-country trip, it will be necessary to
compensate for compass variance and reset the zone.
To change the compass zone through the DIC, see
DIC Compass (Uplevel Only) on page 3-57.
Compass Calibration
The compass can be manually calibrated. To calibrate
the compass through the DIC, seeDIC Compass
(Uplevel Only) on page 3-57.
3-56
DIC Compass (Uplevel Only)
Your vehicle may have a compass in the Driver
Information Center (DIC).
Compass Zone
Under certain circumstances, such as during a long
distance cross-country trip, it will be necessary to
compensate for compass variance and reset the zone
through the DIC.
Compass variance is the difference between the
earth’s magnetic north and true geographic north.
If not adjusted to account for compass variance, the
compass in the vehicle could give false readings.
In order to do this, the compass must be set or
calibrated to the variance zone in which the vehicle
is traveling.To adjust for compass variance, use the following
procedure:
Compass Variance Procedure
1. Press the option button until COMPASS ZONE
displays.
2. Find the vehicle’s current location and variance
zone number on the map.
Zones 1 through 15 are available.
3-57
3. Press the set/reset button to scroll through and
select the appropriate variance zone.
Navigate to one of the trip/fuel menu screens to
view the direction the vehicle is moving. This will be
shown in the top right corner of the DIC display.
4. If you need to calibrate the compass, use the
compass calibration procedure. See “Compass
Calibration Procedure” following.
Compass Calibration
The compass can be manually calibrated. Only calibrate
the compass in a safe location where driving the
vehicle in circles is not a problem. If “CAL” should ever
appear in the DIC display, the compass may need
calibration.To calibrate the compass, use the following procedure:
Compass Calibration Procedure
1. Before calibrating the compass, make sure the
compass zone is set to the variance zone in
which the vehicle is traveling. See “Compass
Variance Procedure” earlier in this section.
2. Press the option button until the COMPASS
CALIBRATION screen is displayed.
3. Press the set/reset button to start the compass
calibration.
4. The DIC will display CALIBRATION BEGUN DRIVE
IN CIRCLES. Drive the vehicle in a circle
until the DIC displays CALIBRATION FINISHED.
The DIC will display CALIBRATION FINISHED
for several seconds and then will display the
COMPASS CALIBRATION screen.

BATTERY SAVER ACTIVE
This message will display when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system will start reducing certain
features of the vehicle that you may be able to notice.
At the point that the features are disabled, this message
is displayed. It means that the vehicle is trying to
save the charge in the battery.
Turn off all unnecessary accessories to allow the battery
to recharge.
The normal battery voltage range is 11.5 to 15.5 volts.
If you have an uplevel DIC, you can monitor the
battery voltage by pressing the gages button until
BATTERY displays.
