This overhead console allows you to choose between a
compass/temperature display and one of four trip con-
ditions being monitored.
US/M Button
Use this button to change the display from U.S. to
METRIC measurement units.
RESET Button
Use this button to reset the following displays:
Average Fuel Economy (AVG ECO)
Trip Odometer (ODO)
Elapsed time (ET)

Global Reset
If the RESET button is pressed twice within two seconds
while in any of the three resettable displays (AVG ECO,
ODO, ET), the Global Reset will reset all three displays.
Step Button
Use this button to choose or cycle through the four trip
conditions.
Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset.
Average fuel economy is a running average of the amount
of fuel used and the distance the vehicle has traveled.
When the fuel economy is reset, the display will momen-
tarily blank. Then, the history will be erased, and the
AVERAGING WILL CONTINUE FROM WHERE IT
WAS BEFORE THE RESET. The reset value is based on
a minimal amount of fuel used and the distance traveled
from the previous drive cycle. The displaymay take
several miles/kilometersfor this value to change depen-
dent upon driving habits.

Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 mi (48 km/h)
estimated driving distance, the DTE display will change
to an alternating test display of ªLOº and ªFUELº. This
display will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the ªLO FUELº text and a new DTE value will be
displayed, based on the current values in the DTE
calculation and the current fuel tank level.NOTE:It is possible for DTE to display ªLO FUELº
before the low fuel warning light turns on in the instru-
ment cluster. This could occur because low fuel warning
is set to a specified fuel tank volume and DTE is an
estimated distance calculation based on fuel economy
and remaining fuel tank volume.
Ram fuel tank volumes are as follows:
²26 gal (98 L) - 1500 short box models
²34 gal (128 L) - 1500 Quad Cabt(if equipped)/2500/
3500/Power Wagon short box models
²35 gal (132 L) - 1500/2500/3500//Power Wagon long
box models

Trip Odometer (ODO)
NOTE:The maximum value is approximately 6000 mi
(9956 km/h). Then the trip odometer must be reset in
order to update the trip odometer miles/kilometers.
This display shows the distance traveled since the last
reset. Resetting of this screen will cause the trip odometer
to change to zero.
Elapsed Time (ET)
This display shows the accumulated ignition ON time
since the last reset. Resetting the Elapsed Time will cause
the display to change to zero.
C/T Button
Use this button to select a readout of the outside tem-
perature and one of eight compass headings that indicate
the direction in which the vehicle is facing.

WARNING!
Even if the display still reads a few degrees above 32É
F ( 0É C), the road surface may be icy, particularly in
woods or on bridges. Drive carefully under such
conditions to prevent an accident and possible per-
sonal injury or property damage.
Automatic Compass Calibration
This compass is self-calibrating which eliminates the
need to manually set the compass. When the vehicle is
new, the compass may appear erratic and the CAL
symbol will be displayed.
After completing up to three 360É turns, with the vehicle
traveling less than 5 mph (8 km/h), in an area free from
large metal or metallic objects, the CAL symbol will turn
off and the compass will function normally.
Manual Compass Calibration
NOTE:To ensure proper compass calibration, make
sure the compass variance is properly set before manu-
ally calibrating the compass.
If the compass appears erratic and the CAL symbol does
not appear, you must manually put the compass into the
ªCalibrationº mode.
Recalibrating The Compass
Turn ON the ignition and set the display to ªCompass/
Temperature.º Press and hold the RESET button to
change the display between VAR (compass variance) and
CAL (compass calibration) modes. When the CAL sym-
bol is displayed, complete one 360É turn in an area free
from large metal objects or power lines. The CAL symbol
will turn off and the compass will function normally.
NOTE:Magnetic materials should be kept away from
the overhead console. This is where the compass sensor is
located.
154 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

Compass Varianceis the difference between magnetic
north and geographic north. In some areas of the country,
the difference between magnetic and geographic north is
great enough to cause the compass to give false readings.
If this occurs, the compass variance must be set according
to the Compass Variance Map.

NOTE:The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to ªCompass/Temperature.º Press and hold the
RESET button approximately five seconds. The last vari-
ance zone number will be displayed. Press the STEP
button to select the new variance zone and press the
RESET button to resume normal operation.
Outside Temperature
Because the ambient temperature sensor is located un-
derhood, engine temperature can influence the displayed
temperature, therefore, temperature readings are slowly
updated when the vehicle speed is below 20 mph (30
km/h) or during stop and go driving.
GARAGE DOOR OPENER Ð IF EQUIPPED
HomeLinktreplaces up to three remote controls (hand-
held transmitters) that operate devices such as garage
door openers, motorized gates, lighting, or home security
systems. The HomeLinktunit operates off of your vehi-
cle's battery.
The HomeLinktbuttons are located in the overhead
console, and contain one, two, or three dots/lines desig-
nating the different HomeLinktchannels.
