fuel cap Ram 4500 Chassis Cab 2018 Owner's Manual

NOTE:
• Under no circumstances should oil changeintervals 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 ex-
ceed 12,500 miles (20 000 km) under any
circumstances. See the Fuel Requirements
section for more information regarding opera-
tion of Chassis Cab models and Pickup mod-
els configured for use with biodiesel blend
(B6-B20) fuel meeting ASTM specification
D-7467.Perform Service Indicator —
Cummins Diesel
Your vehicle will require emissions mainte-
nance at a set interval. To help remind you
when this maintenance is due, the instru-
ment cluster will display “Perform Service”.
When the “Perform Service” message is dis-
played on the instrument cluster it is neces-
sary to have the emissions maintenance per-
formed. Emissions maintenance may include
replacing the Closed Crankcase Ventilation
(CCV) filter element. The procedure for clear-
ing and resetting the “Perform Service” indi-
cator message is located in the appropriate
Service Information.

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 control.
• 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.

ComponentFluid, Lubricant, or Genuine Part
Engine Oil In ambient temperatures above 0°F (-18°C), we recommend you use 15W-40 engine oil such as Mopar, Shell Rotella
and Shell Rimula that meets FCA Material Standard MS-10902 and the API CJ-4 engine oil category is required.
Products meeting Cummins CES 20081 may also be used. The identification of these engine oils is typically located on
the back of the oil container.
In ambient temperatures below 0°F (-18°C), we recommend you use 5W-40
syntheticengine oil such as Mopar, Shell
Rotella and Shell Rimula that meets FCA Material Standard MS-10902 and the API CJ-4 engine oil category is required.
Engine Oil Filter We recommend you use Mopar Engine Oil Filters.
Fuel Filters We recommend you use Mopar Fuel Filter. Must meet 3 micron rating.
Using a fuel filter that does not meet the
manufacturers filtration and water separating requirements can severely impact fuel system life and reliability.
Crankcase Ventilation Filter We recommend you use Mopar CCV Filter.
Fuel Selection Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that you must fuel this
vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the emissions control system.
For most year-round service, No. 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide good
performance.
If climatized or diesel Number 1 ULSD fuel is not available, and you are operating below (20°F/-6°C), in sustained arctic
conditions, Mopar Premium Diesel Fuel Treatment (or equivalent) is recommended to avoid gelling.
This vehicle is fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM specification D-975.
Pickup models,
and Chassis Cab models configured with optional B20 capability, are additionally compatible with 20% biodiesel
meeting ASTM specification D-7467.
Diesel Exhaust Fluid Mopar Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the ISO 22241 standard.
Use of fluids not API Certified to ISO 22241 may result in system damage. You can receive assistance in locating DEF
in the United States by calling 866-RAM-INFO (866-726-4636). In Canada call 1–800–465–2001 (English) or
1–800–387–9983 (French).
