Interior Lights
Courtesy and dome lights are turned on when the front
doors are opened, when the dimmer control (rotating
wheel on the right side of the switch) is rotated to the
upward detent position, or if equipped, when the UN-
LOCK button is pressed on the key fob. When a door is open and the interior lights are on, rotating the dimmer
control all the way down to the OFF detent will cause all
the interior lights to go out. This is also known as the
 Party  mode because it allows the doors to stay open for
extended periods of time without discharging the vehi-
cle’s battery.
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are ON you can
supplement the brightness of the odometer, trip odom-
eter, radio and overhead console by rotating the control
up until you hear a click. This feature is termed the
“Parade” mode and is useful when headlights are re-
quired during the day.
Club Cab/Quad Cab models may have an optional
switched dome lamp that may be operated by pressing
the lens.Dimmer Control122 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

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

for up to 90 seconds when the doors are unlocked with
the remote keyless entry transmitter. To make your
selection, press and release the RESET button until
“OFF,” “30 sec.,” “60 sec.,” or “90 sec.” appears.
• “UNIT IN > US/METRIC” – The EVIC, odometer can
be changed between English and Metric units of
measure. To make your selection, press and release the
RESET button until “US” or “METRIC” appears.
• “COMPASS VARIANCE > 1” – Press the RESET
button to change the compass variance setting. Refer
to Compass Variance, in this section for additional
information.
• “COMPASS CALIBRATE > YES” – Press the RESET
button to calibrate the compass. Refer to Manual
Compass Calibration, in this section for additional
information. Compass/Temperature Button
Pressing the Compass/Temperature button
will return the display to the normal compass/
temperature display.
NOTE: Temperature accuracy can be effected from heat
soak. For best accuracy, the vehicle should be driven at a
speed greater than 25 mph (40 km/h) for several min-
utes.
Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to set the compass manually. When the vehicle is
new, the compass may appear erratic and the EVIC will
display “CAL” until the compass is calibrated. You may
also calibrate the compass by completing one or more
360° turns (in an area free from large metal or metallic
objects) until the “CAL” message displayed in the EVIC
turns off. The compass will now function normally. UNDERSTANDING THE FEATURES OF YOUR VEHICLE 147

CAUTION!Do not leave your vehicle unattended with the
engine running as you would not be able to react to
the temperature indicator if the engine overheats.
NOTE: Engine idle speed will automatically increase to
1000 rpm at elevated coolant temperatures to improve
engine cooling.
NOTE: If the gauge pointer moves to either extreme of
the gauge, the “Check Gages” indicator will illuminate
and a single chime will sound.
14. Security Light
The light will flash rapidly for approximately 16 seconds
when the vehicle theft alarm is arming. The light will
flash at a slower rate after the alarm is set. The security
light will also come on for about two seconds when the
ignition is first turned ON. 15. Transmission Range Indicator (Automatic
Transmissions Only)
When the gear selector lever is moved, this indicator
shows the automatic transmission gear range selected.
16. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
If the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.
The trip odometer shows individual trip mileage. To
toggle between the odometer and the trip odometer,
press the Odometer/Trip Odometer Button. To reset the
Trip Odometer, press and hold the button while in trip
mode, until the Trip Odometer resets. UNDERSTANDING YOUR INSTRUMENT PANEL 175

NOTE: The odometer/trip odometer Vacuum Fluores-
cent Display may also display “gascap”, which indicates
that your gas cap is possibly loose or damaged.
The Vacuum Fluorescent Display will also display “no-
fuse”, which indicates that the IOD fuse is removed from
the Integrated Power Module.
NOTE: There is also an engine hour function. This
indicates the total number of hours the engine has been
running. To display the engine hours perform the follow-
ing: Place the ignition in RUN, but do not start the
engine. With the odometer value displayed, hold the trip
button down for a period of 6 seconds. The odometer will
change to trip value first, then it will display the engine
hour value. The engine hours will be displayed for a
period of 30 seconds until the ignition is turned off or the
engine is started. 17. Check Gages Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.176 UNDERSTANDING YOUR INSTRUMENT PANEL

23. Water In Fuel Indicator—Diesel Only
Indicates there is water detected in the fuel
filter. Refer to the Maintenance section, Drain-
ing Fuel/Water Separator Filter, for water
drain procedure. (See page 410 for more infor-
mation.)
24. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
25. Transmission Oil Temperature Warning Light
(Automatic Transmissions Only)
This light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g. snow plowing, off- road operation). If this light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
26. Wait To Start Indicator—Diesel Only

WARNING!• Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may
change suspension dimensions and performance
characteristics, resulting in changes to steering,
handling, and braking of your vehicle. This can
cause unpredictable handling and stress to steer-
ing and suspension components. You could lose
control and have an accident resulting in serious
injury or death. Use only the tire and wheel sizes
with load ratings approved for your vehicle.
• Never use a tire with a smaller load index or
capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire overload-
ing and failure. You could lose control and have
an accident.
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control. CAUTION!Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
• Fast tire wear.
• Uneven tire wear, such as feathering and one-sided
wear.
• Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.322 STARTING AND OPERATING

WARNING!• Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running. This is in violation of most state and
federal fire regulations and will cause the Mal-
function Indicator Light to turn on.
NOTE: Tighten the gas cap 1/4 turn until you hear one
click. This is an indication that the cap is properly
tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on, Be sure the gas cap is
tightened every time the vehicle is refueled. WARNING!A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap Message
If the vehicles diagnostic system determines that the fuel
filler cap in loose, improperly installed, or damaged, a
GASCAP message will be displayed in the instrument
cluster. Tighten the gas cap until a “clicking” sound is
heard. This is an indication that the gas cap is properly
tightened. Press the odometer reset button to turn the
message off. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice334 STARTING AND OPERATING
