Follow the steps in the “Normal Starting” procedure
except:
1. Pushing the engine start button with the driver ’s footon the brake will move the ignition from OFF or ACC
to RUN, and will illuminate the Wait To Starttelltale.
The engine will not immediately crank, this is normal
operation.
2. The “Wait To Start telltale will remain on for a period
of time that varies depending on the engine tempera-
ture.
3. While the Wait to Start telltale is on, the EVIC/DID
will additionally display a gauge or bar whose initial
length represents the full Wait to Starttime period.
Its length will decrease until it disappears when the
Wait to Start time has elapsed.CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
4. After the engine “Wait To Start” telltale goes off, the engine will automatically crank.
CAUTION!
The engine may automatically crank when the “Wait
To Start” time has elapsed. To abort the automatic
starting process, ensure the driver ’s foot is fully
removed from the brake pedal prior to pushing the
START/STOP button to cycle the ignition off.
210 STARTING AND OPERATING

•A 12 Volt heater built into the fuel filter housings aid 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 Air
Temperature Above 66° F (19° C)
Observe the instrument panel cluster lights when starting
the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission. For vehicles equipped with a manual transmission, fully
press and hold the clutch pedal and shift into NEU-
TRAL. 3. Turn the ignition switch to the ON position and watch
the instrument panel cluster lights.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START the engine before you drain the water
from the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
4. Turn the ignition switch to the START position and crank the engine. Do not press the accelerator during
starting.

2. While theWait To Start” telltale is on, the EVIC/DID
will additionally display a gauge or bar whose initial
length represents the full Wait To Starttime period.
Its length will decrease until it disappears when the
Wait To Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
3. After the “Wait To Start” telltale goes off, turn the ignition switch to the START position. Do not press the
accelerator during starting.
CAUTION!
Do not crank engine for more than 15 seconds at a
time or starter motor damage may result. Turn the
ignition switch to the OFF position and wait at least
two minutes for the starter to cool before repeating
start procedure.
4. After engine start-up, check that the oil pressure warning light has turned off.
5. Allow the engine to idle about three minutes until the manifold heaters have completed the post-heat cycle.
6. Release the parking brake and drive.
NOTE:
•
Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger at
low coolant temperatures to improve engine warm-up.
214 STARTING AND OPERATING

NOTE:Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
2. 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” telltale turns
off and the engine is started, recycle the manifold
heaters by turning the ignition switch to the OFF
position for at least five seconds and then back ON.
3. If the vehicle is driven and vehicle speed exceeds 19 mph (31 km/h) before the manifold heater post-
heat (after start) cycle is complete, the manifold heat-
ers will shut off.
4. If the engine is started before the “Wait To Start” telltale turns off, the preheat cycle will turn off.
5. 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 1,000
RPM and engage the Variable Geometry Turbocharger
at low coolant temperatures to improve engine warm-
up.
• 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. If your engine has run out of fuel, refer to
“Maintenance Procedures/Priming If The Engine Has
Run Out Of Fuel” in “Maintaining Your Vehicle” for
further information.
• If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale goes out, reset the grid heaters by turning the
ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”
216 STARTING AND OPERATING

diesel engine. However, if seasonably adjusted fuel is
not available and you are operating below 20°F (-6°C),
Mopar® Premium Diesel Fuel Treatment (or equiva-
lent) may be beneficial to avoid fuel gelling.
Engine Oil Usage
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for the correct engine oil viscosity.
Winter Front Usage
A winter front or cold weather cover is to be used in
ambient temperatures below 32°F (0°C), especially dur-
ing extended idle conditions to reduce condensation
build-up within engine crankcase. If a winter front or
cold weather cover is to be used, a percentage of the total
grille opening area must be left uncovered to provide
sufficient air flow to the charge air cooler and automatic
transmission oil cooler. The percentage of opening must
be increased with the increasing ambient air temperature
and/or engine load. If the cooling fan can be heardcycling frequently, increase the size of the opening in the
winter front. A suitable cold weather cover is available
from your MOPAR® dealer.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°C). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 VAC
powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPAR® dealer.
Engine Warm-Up
Avoid full throttle operation when the engine is cold.
When starting a cold engine, bring the engine up to
operating speed slowly to allow the oil pressure to
stabilize as the engine warms up.
220 STARTING AND OPERATING

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.
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 on both fuel filters. 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.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
Fuel Specifications
The Cummins® diesel engine has been developed to take
advantage of the high energy content and generally
lower cost No. 2 Ultra Low Sulfur diesel fuel or No. 2
Ultra Low Sulfur climatized diesel fuels. Experience has
shown that it also operates on No. 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.

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.
Fuel Filler Cap
If the fuel filler cap is lost or damaged, be sure the
replacement cap is for use with this vehicle.
CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap. A poorly fitting cap could let impuri-
ties into the fuel system.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel filler cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
4
STARTING AND OPERATING 261

microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
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.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
DEF is subject to freezing at the lowest temperatures. For
example, DEF may freeze at temperatures at or below 12°
F (-11° C). The system has been designed to operate in
this environment.
NOTE: When working with DEF, it is important to know
that:
• Any containers or parts that come into contact with
DEF must be DEF compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or non-stainless
steel should be avoided as they are subject to corrosion
by DEF.
• If DEF is spilled, it should be wiped up completely.
