•
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

If fuses burn out
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).
