If these modified engine performance
characteristics persist for an extended
period and either the service engine soon
or powertrain malfunction, reduced power,
electronic throttle control light is
illuminated, have the system checked by
an authorized dealer.
Service engine soon

power, electronic throttle control
Diesel Lubrication System
It is important to change the engine oil at
the recommended service intervals or
when indicated by the information display
to maintain oil viscosity. Extending the oil
and filter change interval beyond the
recommended interval can negatively
affect engine performance, fuel economy
and engine life. See Engine Oil Check
(page 190).
Engine and secondary cooling system
The cooling system contains a primary
cooling loop to cool the engine and a
secondary cooling loop to cool the
transmission, charge air, and fuel. The
coolant serves three primary purposes: to
provide heat transfer, freeze point
protection, and corrosion protection using
additives.
Vehicles with diesel engines typically are
used to carry heavy loads and accumulate
mileage rapidly. These two factors may
cause the additives in the coolant to wear
out in a shorter time. You can find more
information about coolant additives and
coolant change intervals in the coolant
chapter. See
General Maintenance
Information (page 320). Operating the
engine with insufficient coolant or coolant
additive can cause severe engine damage. Selective catalytic reduction system
Your vehicle is equipped with a selective
catalytic reduction system designed to
reduce emission levels of nitrogen oxides
from the exhaust of your diesel engine. This
system relies on the use of Diesel Exhaust
Fluid (DEF) that you must replenish at
certain intervals. Failure to maintain proper
DEF levels or if the DEF becomes
contaminated will result in vehicle speed
limitations or result in your vehicle entering
an idle-only mode. See
Selective
Catalytic Reductant System (page 105).
Minor Troubleshooting Guide
If the engine won ’t crank WARNING
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to the start position, the lights
become dim or go out, the battery
connections may be loose or corroded, or
the battery may be discharged. If there is
a clicking or stuttering sound coming from
the engine compartment when you turn
the key to the start position, this may also
indicate a loose or corroded battery
connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.

•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, See
Jump Starting the Vehicle (page 155).
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump.
• Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive •
Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter
If fuses burn out WARNING
Replacement fuses and circuit
breakers must always be the same
rating as the original equipment
shown. Never replace a fuse or circuit
breaker with one of a higher rating. Higher
rated fuses or circuit breakers could allow
circuit overloading in the event of a circuit
malfunction, resulting in severe vehicle
damage or personal injury due to fire. Burned-out or blown fuses usually indicate
an electrical short-circuit, although a fuse
may occasionally burn out from vibration.
Insert a second fuse. If this fuse
immediately burns out and you cannot
locate the cause, return your vehicle to
your dealer for a circuit check. See
Changing a Fuse
(page 174).
Selective catalytic reduction system
speed limit and Idle-only modes
If the vehicle ’s speed is limited or in an
idle-only mode, the selective catalytic
reduction system may be limiting the
vehicle ’s functions due to low or
contaminated DEF. Check the DEF. See
Selective Catalytic Reductant System
(page
105).

NOISE POLLUTION CONTROL
In order to keep to the federal exterior
noise regulations, your vehicle may be
equipped with noise emission items.
Depending on your vehicle configuration,
it may have all or some of the following
items:
Air Intake System
Inspect the air cleaner. Do not alter its
location. Do not alter inlet and outlet
piping.
Body
Inspect wheel well splash shields, cab
shields and under hood insulation for
deterioration, dislocation and orientation.
Cooling System
• Inspect the fan for blade damage. If
you find any damage, replace with the
recommended parts. Inspect for
fan-to-shroud interference and any
damage to shroud, such as cracks and
holes.
• Do not change fan ratio or alter fan
spacer dimensions and positions. •
Inspect fan clutch for proper operation.
Make sure the fan is disengaged when
cooling of the engine is not required.
• Inspect radiator shutters (if equipped)
for proper operation. The shutters
should be open during normal
operating temperatures.
Engine
Valve covers and block covers damp-out
engine mechanical noise. If they need
replacing, make sure to replace them with
the recommended parts. Check for
mechanical isolations.
Transmission Enclosure
Inspect for cracks, holes and tears. Clean
any deposits, such as oil, dirt and stones.
Exhaust System
• Inspect for leaks at various joint
connections and loose clamps.
• Perform a visual inspection for cracks
or holes in the muffler and tail pipe.
• Always use the recommended
replacement parts.
• Do not change the tail pipe elbow or
offset tail pipe orientation from the
standard position as originally received.
• To avoid abnormal changes in vehicle
sound levels, it is necessary for the
owner to perform inspections and
necessary maintenance at specified
intervals. See Scheduled
Maintenance (page 320).

Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop the vehicle,
switch off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by an
authorized dealer.
Engine Coolant Temperature
Gauge
WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator is in the normal range. If the
engine coolant temperature exceeds the
normal range, stop the vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grille.
Special operating conditions, such as
snowplowing, towing or off-road use, can
cause higher than normal operating
temperatures. See Special Operating
Conditions Scheduled Maintenance
(page
330). Operating the transmission for extended
periods with the gauge in the higher than
normal area may cause internal
transmission damage. We recommend
altering the severity of the driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, contact an authorized
dealer.
Fuel Gauge
Note:
The fuel gauge may vary slightly
when your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge
indicates approximately how much fuel is
in the fuel tank. The arrow adjacent to the
fuel pump symbol indicates on which side
of your vehicle the fuel filler door is located.
The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.
After refueling, some variability in needle
position is normal:
• It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.
• The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.
• If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.
