Priming If The Engine Has Run
Out Of Fuel
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.
1. Add a substantial amount of fuel to the tank, approximately 2 to 5 gal (8L to
19L).
2. Turn ignition switch to the start position to engage starter for one second, return ig-
nition switch to run position. This will
activate in tank fuel pump for approxi-
mately 15 seconds. Repeat this process
twice.
3. Start the engine using the “Normal Start- ing” procedure. Refer to “Starting Proce-
dures” in “Starting and Operating” for
further information.
CAUTION!
Do not engage the starter motor for more
than 15 seconds at a time. Allow two
minutes between the cranking intervals.
NOTE:
The engine may run rough until the air is
forced from all the fuel lines.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system. NOTE:
• A maximum blend of 5% biodiesel, meet-
ing ASTM specification D-975 may be used
with your Cummins diesel engine. (Chassis
Cab models not configured with B20 capa-
bility.)
• A maximum blend of 20% biodiesel, meet- ing ASTM specification D-7467 may be
used with your Cummins diesel engine.
(Pickup models and Chassis Cab models
configured with B20 capability.)
• Use of biodiesel mixture in excess of 20% can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• Ethanol blends are not recommended or approved for use with your Cummins diesel
engine.
• In addition, commercially available fuel ad- ditives are not necessary for the proper
operation of your Cummins diesel engine.

Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of your tire (sidewall damage is not repair-
able).
• The puncture is no greater thana¼ofan inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat
tire of identical size and service description
(Load Index and Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi
(96 kPa). Once a Run Flat tire reaches the
run flat mode it has limited driving capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer while
a tire is in the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30 sec-
onds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.

• Dual wheel models require a special heavy-duty lug nut tightening adapter (included
with the vehicle) to correctly tighten the lug
nuts. Also, when it is necessary to remove
and install dual rear wheels, use a proper
vehicle lifting device.
NOTE:
When installing a spare tire as part of a dual
rear wheel end combination, the tire diam-
eter of the two individual tires must be com-
pared. If there is a significant difference, the
larger tire should be installed in a front loca-
tion. The correct direction of rotation for dual
tire installations must also be observed. These dual rear wheels should be tightened as
follows:
1. Tighten the wheel nuts in the numbered
sequence to a snug fit. 2. Retighten the wheel nuts in the same
sequence to the torques listed in the
table. Go through the sequence a second
time to verify that specific torque has
been achieved. Retighten to specifica-
tions at 100 miles (160 km) and after
500 miles (800 km).
• It is recommended that wheel stud nuts be kept torqued to specifications at all times.
Torque wheel stud nuts to specifications at
each lubrication interval.
