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 18
mph (29 km) before the manifold heater post-heat
(after start) cycle is complete, the manifold heaters will
shut off.
•If the engine is started before the WAIT TO START
light turns off, the preheat cycle will turn off.
•If the engine is cranked for more than 10 seconds, the
post-heat cycle will turn off.NOTE:Engine idle speed will automatically increase to
1000 rpm at low coolant temperatures to improve engine
warm-up.
NOTE:When a diesel engine is allowed to run out of
fuel or the fuel gels at low temperatures, air is pulled into
the fuel system.
You may try priming as described below.
1. Add a substantial quantity of fuel to the tank (5 to 10
gallons) or eliminate the gelled fuel condition.
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.

Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from
the fuel/water separator using the fuel/water separator
drain provided. If you buy good quality fuel and follow
the cold weather advice above, fuel conditioners should
not be required in your vehicle. If available in your area,
a high cetane “premium” diesel fuel may offer improved
cold-starting and warm-up performance.
ADDING FUEL
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is properly
tightened.
•Make sure that the gas cap is tightened each time the
vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a container
that is inside of a vehicle or in the bed or on the
opened tailgate. Always place fuel containers on the
ground while filling.

ADDING FUEL — 24–VALVE CUMMINS TURBO
DIESEL
WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be
burned. Always place fuel containers on the ground
while filling.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
You may try priming as described below. However, if the
engine will not start, refer to the fuel priming procedure
in the Service Manual or have the vehicle towed to an
authorized Dodge dealer.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19 to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.

If more than a couple ounces of fuel has been drained,
follow the directions below for “Priming if the engine has
run out of fuel.”
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Priming if the engine has run out of fuel
1. Add a substantial quantity of fuel to the tank 5 to 10
gallons (19L to 38L).
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue torun and purge air from the system for about 25 seconds.
After 25 seconds, attempt to start the engine again.
3. Start the engine using the Normal Starting Procedure.
4. Repeat the procedure if the engine does not start.
CAUTION!
Do not engage the starter motor for more than 15
seconds at a time. Allow two minutes between the
cranking intervals.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
