2007 RAM CHASSIS CAB Owners Manual

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 miles estimated
driving distance, the DTE display will change to an
alternating test display of “LO” and “FUEL”. This dis-
play will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the “LO FUEL” 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 “LO FUEL”
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:
• 52 gallons - Standard rear tank
• 22 gallons - Optional Midship Tank
Trip Odometer (ODO)
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. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 137

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
32°F ( 0°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 360° 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.138 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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
“Calibration” mode.
Recalibrating The Compass
Turn on the ignition and set the display to “Compass/
Temperature.” 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 slowly drive the vehicle 5 mph in a
complete 360° circle in an area free from large metal
objects or power lines. The CAL symbol will turn off and
the compass will function normally. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 139

Compass Variance is 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. 140 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

NOTE: The default for the compass variance is zone 8.
To set the variance: Turn the ignition ON and set the
display to “Compass/Temperature.” 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. OVERHEAD CONSOLE WITH ELECTRONIC
VEHICLE INFORMATION CENTER (EVIC) —
DIESEL ONLY
The overhead console contains dome/reading lights, and
an Electronic Vehicle Information Center (EVIC).
Dome/Reading Lights
Located in the overhead console are two dome/reading
lights.
The dome/reading lights illuminate when a door is
opened or when the interior lights are turned on by
rotating the dimmer control located on the Headlight
Switch.
The reading lights are activated by pressing on the
recessed area of the corresponding lens. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 141

NOTE: The dome/reading lights will remain on until
the switch is pressed a second time, so be sure they have
been turned off before leaving the vehicle. Electronic Vehicle Information Center (EVIC) — If
Equipped
Pressing the menu button will change the
display to one of the following features:
Trip Functions
Pressing the STEP button allows you to scroll through
one of the following Trip Function features:
• TRIP – Shows the total distance traveled since the last
reset. To reset the TRIP function, press and hold the
RESET button.
• ELAPSED TIME – Shows the total elapsed time of
travel since the last reset. Elapsed time will increment
when the ignition switch is in the ON/RUN or START
positions.
• UNIT IN US/METRIC – Press the RESET button to
toggle between US and METRIC.Overhead Console with EVIC142 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

• AVG. MPG – Shows the average fuel economy since
the last reset. When the fuel economy is reset, the
display will show dashes for two seconds. Then the
history information will be erased, and the averaging
will continue from the last fuel average reading before
the reset. (Example: If your Electronic Vehicle Informa-
tion Center (EVIC) displays 18 AVG. MPG and the
RESET button is pressed, the previous averaging his-
tory will be erased and the display will return to the 18
AVG. MPG, not to 0 AVG. MPG). The display may take
several miles for the value to change dependent upon
driving habits.
• MI TO EMPTY (Distance To Empty) – Shows the
estimated distance that can be traveled with the fuel
remaining in the tank. This estimated distance is
determined by a weighted average of fuel economy,
according to the current fuel tank level. Distance MI
TO EMPTY cannot be reset through the RESET button. 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 miles (48 km)
estimated driving distance, the DTE display will
change to a text display of  LOW FUEL.  This display
will continue until the vehicle runs out of fuel. Adding
a significant amount of fuel to the vehicle will turn off
the  LOW FUEL  text and a new DTE value will
display.
