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 the9Party9mode because it allows the
doors to stay open for extended periods of time without
discharging the vehicle'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
ªParadeº mode and is useful when headlights are re-
quired during the day.Battery Saver
To protect the life of your vehicle's battery, Load Shed-
ding is provided for both the interior and exterior lights.
If the ignition is off and any door is left ajar for 15
minutes or the dimmer control is rotated upwards for 15
minutes, the interior lights will automatically turn off.
If the headlamps remain on while the ignition is cycled
off, the exterior lights will automatically turn off after 5
minutes. After 5 minutes timeout, if the headlamp switch
is turned off and then turned on, the exterior lights will
automatically turn off after 15 minutes.
If the dimmer control is rotated to the cargo lamp
position with the ignition off, the cargo lamps will
automatically turn off after 15 minutes.
NOTE:Battery Saver mode is cancelled if the ignition is
ON.

Headlamp Delay Ð If Equipped
To aid in your exit, your vehicle, if equipped, can be
programmed by your dealer with a headlamp delay that
will leave the headlamps on for 0, 30, 60, or 90 seconds.
This delay is initiated when the ignition is turned OFF
while the headlamp switch is on, and then the headlamp
switch is cycled off. The headlamps will remain on for 60
seconds. Headlamp delay can be cancelled by either
turning the headlamp switch ON then OFF or by turning
the ignition ON.
Headlights, Parking Lights, Panel Lights
When the headlight switch is rotated to the first
position, the parking lights, taillights, side marker
lights, license plate light and instrument panel
lights are all turned on. Rotating the headlight switch to
the first position will also turn on the cab top clearance
lights, flare lights, and tailgate lights if the vehicle is
equipped with these lights. The headlights will turn ON
when the switch is rotated to the second position. The9LAMP OUT9indicator will be illuminated in the instru-
ment cluster if a defective bulb or wiring circuit is
detected for the headlamp system.

WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
NORMAL OPERATION
Observe the following when the engine is operating.
²All message center lights are off.
²Check Engine Lamp is off.
²Engine Oil Pressure is above 10 psi (69 kPa) at idle.
²Low Oil Pressure light is off.
²Voltmeter Operation:
²The voltmeter may show a gauge fluctuation if
certain engine temperatures are below 66ÉF (19ÉC).
This cycling operation is caused by the post-heatcycle of the intake manifold heater system. The
number of cycles and the length of the cycling
operation is controlled by the engine control mod-
ule, this time will not exceed 150 seconds. The
needle should then stabilize at the approximate
operation point.
²The cycling action will cause temporary dimming of
the headlamps, interior lamps, and also a noticeable
reduction in blower motor speed.
Cold Weather Precautions
Operation in ambient temperature below 32ÉF (0ÉC) may
require special considerations. The following charts sug-
gest these options:

Fuel Operating Range
*No. 1 diesel fuel should only be used where extended
arctic conditions (-10ÉF/-23ÉC) exist.
NOTE:
²Use of Climatized Diesel Fuel or Number 1 Diesel Fuel
results in a noticeable decrease in fuel economy.
²Climatized Diesel Fuel is a blend of Number 2 and
Number 1 Diesel Fuels which reduces the temperature
at which wax crystals form in fuel.NOTE:Refer to Fuel Requirements in this section for
further details on fuel recommendations.
Engine Block Heater
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground±fault interrupter protected 110±115 volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
The engine block heater cord is routed under the hood to
the right side and can be located just behind the grille
near the headlamp.
NOTE:The engine block heater cord is a factory in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized Mopartdealer.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
212 STARTING AND OPERATING

ENGINE RUNAWAY
WARNING!
In case of engine runaway due to flammable fumes
from gasoline spills or turbocharger oil leaks being
sucked into the engine do the following to help
avoid personal injury and/or vehicle damage:
1. Shut off engine ignition switch.
2. Using a CO
2or dry chemical type fire extin-
guisher, direct the spray from the fire extinguisher
into the grille on the passenger side so that the spray
enters the engine air intake.
The inlet for the engine air intake is located behind the
passenger side headlamp and receives air through the
grille
FUEL REQUIREMENTS
Use good quality diesel fuel from a reputable supplier in
your Dodge truck. For most year-round service, No. 2
diesel fuel meeting ASTM specification D-975 will pro-
vide good performance. If the vehicle is exposed to
extreme cold (below 20ÉF or -7ÉC), or is required to
operate at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or dilute the No.
2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the
fuel filters.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
