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
Powertrain malfunction, reduced
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 192).
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 322). 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 156
).
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 176).
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).
