VAN CONVERSIONS/CAMPERS
The Manufacturer’s Warranty does not apply to body
modifications or special equipment installed by van
conversion/camper manufacturers/ body builders. See
the Warranty information book, Section 2.1.C. Such
equipment includes video monitors, VCRs, heaters,
stoves, refrigerators, etc. For warranty coverage and
service on these items, contact the applicable manufac-
turer.
Operating instructions for the special equipment in-
stalled by the conversion/camper manufacturer should
also be supplied with your vehicle. If these instructions
are missing, please contact your selling dealer for assis-
tance in obtaining replacement documents from the
applicable manufacturer.
VEHICLE IDENTIFICATION NUMBER
The vehicle identification number (VIN) is found on a
stamped plate located on the left front corner of the
instrument panel pad, visible from outside of the vehicle

STARTING PROCEDURES
The Cummins Diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 volt AC electrical
outlet with a grounded, three-wire extension cord.
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 Mopardealer.
•A 12–volt heater built into the fuel filter housing aids
in preventing fuel gelling. It is controlled by a built-in
thermostat.
•A heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure — Engine Manifold
AirTemperature Above 66°F (19°C)
Observe the Instrument Panel Cluster lights when start-
ing the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission. Fully
depress and hold the clutch and shift into NEUTRAL for
a manual transmission. Models with manual transmis-
sion are equipped with a clutch interlocking cranking
system. The clutch must be fully depressed to start the
vehicle.
3. Turn the ignition key to the ON position and look at
the instrument panel cluster lamps.
STARTING AND OPERATING 253

certain engine temperatures fall below 66°F (19°C) the
lamp will remain on indicating the intake manifold
heater system is active.
Follow the steps in the Normal Starting Procedure ex-
cept:
CAUTION!
Do not crank engine for more than 15 seconds at a
time or starter motor damage may result. Turn key to
OFF and wait at least 2 minutes for starter to cool
before repeating start procedure.
•The WAIT TO START light will remain on for a period
of time (length of time depends on engine tempera-
ture) after completion of the bulb check.
•After the WAIT TO START light goes off, turn the
ignition key to START. Do not press the accelerator
during starting.
•After engine start-up, check to see that there is oil
pressure.
•Allow the engine to idle about three minutes until
the manifold heaters have completed the post-heat
cycle.
•Release the parking brake and drive.
NOTE:Engine idle speed will automatically increase to
1000 rpm at low coolant temperatures to improve engine
warm-up.
NOTE:If the engine stalls or if the ignition switch is left
On for more than 2 minutes after the WAIT TO START
light goes out, reset the grid heaters by turning the
STARTING AND OPERATING 255

ignition switch to Off for at least 5 seconds and then back
On. Repeat steps 3 through 7 of the normal starting
procedure.
For Extremely Cold Weather Starting — Engine
Manifold Air Temperature Below 0°F (- 18°C)
In extremely cold weather below 0°F (- 18°C) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF for at least 5 seconds and
then back ON after the WAIT TO START light has gone
off, but before the engine is started. However, repeated
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
NOTE: If multiple pre-heat cycles are used before
starting, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
•If the engine stalls after the initial start, the ignition
must be turned to the OFF position for at least 5
seconds and then to the ON position to recycle the
manifold heaters.
NOTE:Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
•Heat generated by the manifold heaters dissipates
rapidly in a cold engine. If more than two minutes
pass between the time the WAIT TO START light goes
OFF and the engine is started, recycle the manifold
heaters by turning the ignition OFF for at least 5
seconds and then back ON.
•If the vehicle is driven and vehicle speed exceeds 19
mph (31 km) before the manifold heater post-heat
(after start) cycle is complete, the manifold heaters will
shut off.
256 STARTING AND OPERATING

•Voltmeter Operation:
•The voltmeter may show a gauge fluctuation if certain
engine temperatures are below 66°F (19°C). This
cycling operation is caused by the post-heat cycle of
the intake manifold heater system. The number of
cycles and the length of the cycling operation is
controlled by the engine control module, this time
will not exceed 150 seconds. The needle should then
stabilize at the approximate operation point.
•The 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 32°F (0°C) 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 (-10°F/-23°C) exist.
NOTE:
•Use of Climatized Diesel Fuel or Number 1 Diesel Fuel
results in a noticeable decrease in fuel economy.
•Climatized 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 Mopardealer.
The block heater must be plugged in at least one hour to
have an adequate warming effect on the coolant.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110–115 volt electrical cord could
cause electrocution.
NOTE:The block heater will require 110 Volts AC and
6.5 Amps to activate the heater element.
Block Heater Usage
A.Temperatures below 0°F (-18°C)
•Block Heater Required for 15W-40
•Block Heater Recommended for 5W-40
B.Temperatures below - 20°F (-29°C)
•Block Heater Required for 5W-40
260 STARTING AND OPERATING

JUMP-STARTING
WARNING!
To prevent personal injury or damage to clothing, do
not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from battery
vent holes. Always wear eye protection when work-
ing with batteries.
Do not use a booster battery or any other booster
source that has a greater than 12 volt system, i.e. do
not use a 24 volt power source.
NOTE:Replacement batteries should both be of equal
size to prevent damage to the vehicles charging system.
Your vehicle is equipped with two 12–volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle’s engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.
