CAUTION!
• DO NOT OVERFILL. DEF will freeze be-low 12ºF (-11ºC). The DEF system is
designed to work in temperatures below
the DEF freezing point, however, if the
tank is overfilled and freezes, the system
could be damaged.
• When DEF is spilled, clean the area immediately with water and use an ab-
sorbent material to soak up the spills on
the ground.
• Do not attempt to start your engine if DEF is accidentally added to the diesel
fuel tank as it can result in severe dam-
age to your engine, including but not
limited to failure of the fuel pump and
injectors.
CAUTION!
• Never add anything other than DEF tothe tank – especially any form of hydro-
carbon such as diesel fuel, fuel system
additives, gasoline, or any other
petroleum-based product. Even a very
small amount of these, less than
100 parts per million or less than 1 oz.
per 78 gallons (295 liters) will contami-
nate the entire DEF system and will
require replacement. If owners use a
container, funnel or nozzle when refilling
the tank, it should either be new or one
that is has only been used for adding
DEF. Mopar provides an attachable
nozzle with its DEF for this purpose.
3. Stop filling the DEF tank immediately when any of the following happen: DEF
stops flowing from the fill bottle into the
DEF tank, DEF splashes out the filler
neck, or a DEF pump nozzle automatically
shuts off.
4. Reinstall cap onto DEF tank. Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F
(-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank.
Extra care should be taken when filling with
portable containers to avoid overfilling. Note
the level of the DEF gauge in your instrument
cluster. You may safely add a maximum of
2 gallons (7.5 Liters) of DEF from portable
containers when your DEF gauge is reading ½
full.

NOTE:
The positive battery post may be covered with
a protective cap if equipped. Lift up on the
cap to gain access to the positive battery
post. Do not jump off fuses. Only jump di-
rectly off positive post which has a positive
(+)symbol on or around the post.
WARNING!
• Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan blades.
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
1. Apply the parking brake, shift the auto- matic transmission into PARK and turn
the ignition to LOCK. 2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper
cables reach, apply the parking brake and
make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other
as this could establish a ground connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of
the booster vehicle or the discharged ve-
hicle.
Connecting The Jumper Cables
1. Connect the positive (+)end of the jumper
cable to the positive (+)post of the dis-
charged vehicle.
NOTE:
Do not jump off fuses. Only jump directly off
positive post.
2. Connect the opposite end of the positive (+) jumper cable to the positive (+)post of
the booster battery.
3. Connect the negative (-)end of the jumper
cable to the negative (-)post of the
booster battery.
4. Connect the opposite end of the negative (-)jumper cable to a good engine ground
(exposed metal part of the discharged
vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in

Once A Month
• Inspect the batteries, and clean andtighten the terminals as required.
• Check the fluid levels of the coolant reser- voir, brake master cylinder, and automatic
transmission (if equipped), and add as
needed.
At Each Oil Change
• Change the engine oil filter.
• Inspect the exhaust system.
• Inspect engine air filter.
• Check the coolant level, hoses, and clamps.
• Inspect front end, and lubricate — If equipped with serviceable fittings.
• Lube the front drive shaft fitting (4X4 mod- els only).
Inspection and service should also be per-
formed anytime a malfunction is observed or
suspected. Retain all receipts.Oil Change Indicator System —
Cummins Diesel
Your vehicle is equipped with an engine oil
change indicator system. This system will
alert you when it is time to change your
engine oil by displaying the words “Oil
Change Due” in your instrument cluster dis-
play. The oil change reminder will remind the
owner to change the engine oil every
15,000 miles or 500 hours, whichever
comes first, except for the Chassis Cab mod-
els and Pickup models configured with op-
tional B20 capability that are using B20 bio-
diesel, which are 12,500 miles or 400 hours,
whichever comes first. Failure to change the
engine oil per the maintenance schedule can
result in internal engine damage. Replace the engine oil and oil filter every
15,000 miles (24,000 km) or six months, or
sooner if prompted by the oil change indicator
system. Under no circumstances should oil
change intervals exceed 15,000 miles
(24,000 km) or six months, whichever comes
first.
NOTE:
• Under no circumstances should oil change
intervals exceed 15,000 miles
(24,000 km) or six months or 500 Hours,
whichever comes first.
• Replace the engine oil and oil filter every 12,500 miles (20 000 km) when running
B20 fuel (Chassis Cab Only).
If Chassis Cab models and Pickup models
configured with optional B20 capability are
operated with greater than 5% levels of bio-
diesel, the oil change interval must not exceed
12,500 miles (20 000 km) under any circum-
stances. See the Fuel Requirements section
for more information regarding operation of
Chassis Cab models and Pickup models con-
figured for use with biodiesel blend (B6-B20)
fuel meeting ASTM specification D-7467.SERVICING AND MAINTENANCE

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.

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure. Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.
