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 under 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, meeting ASTM
specification D-975 may be used with your Cummins
diesel engine. (Chassis Cab models not configured
with B20 capability.)
• A maximum blend of 20% biodiesel, meeting 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 nega-
tively impact the fuel filter’s ability 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 additives are
not necessary for the proper operation of your Cum-
mins diesel engine.
Intervention Regeneration Strategy — Message
Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in one of
the lowest emitting diesel engines ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. The engine and exhaust after-treatment system work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for further information.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be

WARNING!(Continued)
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key
component of selective catalytic reduction (SCR) systems,
which help diesel vehicles meet stringent emission regu-
lations. DEF is a liquid reducing agent that reacts with
engine exhaust in the presence of a catalyst to convert
smog-forming nitrogen oxides (NOx) into harmless ni-
trogen and water vapor.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information. 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)
Maintenance-Free Batteries
The top of the maintenance-free batteries are perma-
nently sealed. You will never have to add water, nor is
periodic maintenance required.
NOTE:
Replacement batteries should both be of equal
capacity to prevent damage to the vehicle’s charging
system.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
(Continued)

MAINTAINING YOUR VEHICLE 353

CAUTION!(Continued)
negative post. Battery posts are marked (+) positive
and negative (-) and are identified on the battery
case. Also, if a “fast charger” is used while the battery
is in vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
WARNING!
Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Always wash hands
after handling the battery.
Battery Blanket Usage
A battery loses 60% of its cranking power as the battery
temperature decreases to 0°F (-18°). For the same de-
crease in temperature, the engine requires twice as much
power to crank at the same RPM. The use of 120 Volt AC powered battery blankets will greatly increase starting
capability at low temperatures. Suitable battery blankets
are available from your authorized MOPAR dealer.
Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator is hot.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or
rusty in appearance, the system should be drained,
354 MAINTAINING YOUR VEHICLE

flushed and refilled with fresh coolant. Check the front of
the A/C condenser (if equipped) or radiator for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the
face of the A/C condenser (if equipped) or the back of the
radiator core.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks.
With the engine at normal operating temperature (but
not running), check the cooling system pressure cap for
proper vacuum sealing by draining a small amount of
engine coolant (antifreeze) from the radiator drain cock.
The radiator drain cock is located in the lower radiator
tank. If the cap is sealing properly, the engine coolant(antifreeze) will begin to drain from the coolant expan-
sion bottle. DO NOT REMOVE THE COOLANT PRES-
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain Flush And Refill
If the engine coolant (antifreeze) is dirty or contains a
considerable amount of sediment, clean and flush with a
reliable cooling system cleaner. Follow with a thorough
rinsing to remove all deposits and chemicals. Properly
dispose of old engine coolant (antifreeze).
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.

MAINTAINING YOUR VEHICLE 355

CAUTION!
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine
damage and may decrease corrosion protection.
Organic Additive Technology (OAT) engine cool-
ant is different and should not be mixed with
Hybrid Organic Additive Technology (HOAT) en-
gine coolant (antifreeze) or any “globally compat-
ible” coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into the cooling
system in an emergency, the cooling system will
need to be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032), by an au-
thorized dealer as soon as possible.
(Continued)
CAUTION! (Continued)
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (an-
tifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that al-
lows extended maintenance intervals. This engine cool-
ant (antifreeze) can be used up to ten years or 150,000
miles (240,000 km) before replacement. To prevent reduc-
ing this extended maintenance period, it is important that
356 MAINTAINING YOUR VEHICLE

you use the same engine coolant (OAT coolant conform-
ing to MS.90032) throughout the life of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) engine coolant (antifreeze)
that meets the requirements of FCA Material Standard
MS.90032. When adding engine coolant (antifreeze):
•We recommend using MOPAR Antifreeze/Coolant 10
Year/150,000 Mile Formula OAT (Organic Additive
Technology) that meets the requirements of FCA Ma-
terial Standard MS.90032.
• Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of FCA Material Standard
MS.90032 and distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below 34°F
(37°C) are anticipated. •
Use only high purity water such as distilled or deion-
ized water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:
• Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could
lead to severe internal engine damage. If any coolant is
needed to be added to the system, please contact your
local authorized dealer.
