CAUTION!
If WATER IN FUEL indicator light remains on DO
NOT START engine before you drain water from the
fuel filter to avoid engine damage. See Section 7 —
Maintaining Your Vehicle, for water drain proce-
dures.
4. Turn the ignition key to START and crank the engine.
Do not press the accelerator during starting.
CAUTION!
Do not crank engine for more than 15 seconds at a
time as starter motor damage may result. Turn key to
OFF and wait at least two minutes before trying
again.
5. When the engine starts, release the key.
6. Check to see that there is oil pressure.
7. Release the parking brake.
Starting Procedure — Engine Manifold Air
Temperature Below 66°F (19°C)
NOTE: The temperature displayed on the overhead
console (if equipped) does not necessarily reflect the
engine manifold air temperature. When 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 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
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
256 STARTING AND OPERATING

Starting Fluids
WARNING!
STARTING FLUIDS or flammable liquids are
NEVER TO BE USED in the Cummins Diesel (see
Warning label). Never pour diesel fuel, flammable
liquid, starting fluids (ether) into the air cleaner
canister, air intake piping, or turbocharger inlet in an
attempt to start the vehicle. This could result in a
flash fire and explosion causing serious personal
injury and engine damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
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 (DIESEL ENGINE)
Observe the following when the engine is operating.
•All message center lights are off.
•Check Engine Lamp is off.
•Engine Oil Pressure is above 10 psi (69 kPa) at idle.
•Low Oil Pressure light is off.
STARTING AND OPERATING 259

Always check the condition of the used oil. This can give
you an indication of some engine problems that might
exist.
•Thin, black oil indicates fuel dilution.
•Milky discoloration indicates coolant dilution.
Clean the area around the oil filter base. Remove the filter
from the underside of the vehicle using a cap style oil
filter wrench.
Clean the gasket surface of the filter mount. The filter
gasket can stick on the filter mount. Make sure it is
removed.
Change the engine oil filter with every engine oil change.
Only a high quality MOPAR filter should be used to
assure most efficient service.
CAUTION!
The filtering medium of other aftermarket filters
may disintegrate. Debris from failed filters may plug
the piston oil cooling nozzles, resulting in scuffed
pistons and engine failure.
CAUTION!
Fill the oil filter element with clean oil before
installation. Use the same type oil that will be used
in the engine. When filling the oil filter, prevent
foreign material from falling into the filter. Severe
engine damage may occur.
Apply a light film of lubricating oil to the sealing surface
of the filter gasket before installing the filter.

Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the batteries and clean and tighten the termi-
nals as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
•Check Filter Minder™. Replace air cleaner filter
element if necessary.
•Check all lights and all other electrical items for correct
operation.
•Drain water from the fuel filter. At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the U-Joints ( if equipped) and front suspen-
sion components.
•Check the automatic transmission fluid level.
•Check the manual transmission fluid level.
•Check the coolant level, hoses, and clamps.
•Lubricate outer tie rod ends.
•Lubricate Front Drive Shaft Fittin
