a maximum speed of 5 MPH.
RAM Active Air System
Your vehicle is equipped with an advanced Ram Active
Air system that provides enhanced performance, espe-
cially when towing under demanding hot or high alti-
tude conditions. If the EVIC/DID displays the message
“Active Airbox Service Required See Dealer”, vehicle
performance may be reduced until service is performed
by an authorized RAM dealer.
Fuel Filter Life Reset
The cluster will display the “Service Fuel Filter” message
when the fuel filter maintenance life is less than 5%. To
check the remaining fuel filter life, go to the “Fuel Filter
Life” screen in the “Vehicle Info” menu. When this
message appears, dealers should replace both frame
mounted and engine mounted fuel filters. NOTE:
Use the steering wheel EVIC controls for the
following procedure(s)

ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 7 of
“Keyless Enter-N-Go Starting Procedure – Engine
Manifold Air Temperature Below 66° F (19° C).”
Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer. •
A 12 Volt heater built into the fuel filter housings aid in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure — Engine Manifold Air
Temperature Above 66° F (19° C)
Observe the instrument panel cluster lights when starting
the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission. For vehicles equipped with a manual transmission, fully
press and hold the clutch pedal and shift into NEU-
TRAL.

Starting Procedure — Engine Manifold Air
Temperature 0°F To 66°F (–18°C to 19°C)
NOTE:The temperature displayed in the Electronic
Vehicle Information Center (EVIC) or Driver Information
Display (DID) does not necessarily reflect the engine
manifold air temperature. Refer to “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information. When engine temperatures fall
below 66°F (19°C) the “Wait To Start Light” will remain
on indicating the intake manifold heater system is active.
Follow the steps in the “Normal Starting” procedure
except:
1. The “Wait To Start” telltale will remain on for a period of time that varies depending on the engine tempera-
ture. 2. While the
Wait To Start” telltale is on, the EVIC/DID
will additionally display a gauge or bar whose initial
length represents the full Wait To Starttime period.
Its length will decrease until it disappears when the
Wait To Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for fur-
ther information.
3. After the “Wait To Start” telltale goes off, turn the ignition switch to the START position. Do not press the
accelerator during starting.

WARNING!
In case of engine runaway due to flammable fumes
from fuel spills or turbocharger oil leaks being
sucked into the engine, do the following to help
avoid personal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire extinguisher,
direct the spray from the fire extinguisher into the
grille on the passenger side so that the spray enters
the engine air intake.
The inlet for the engine air intake is located behind
the passenger side headlamp and receives air
through the grille.
FUEL REQUIREMENTS
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 (formerly known as the American Society for
Testing and Materials) specification D-975 Grade S15 will
provide good performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is required to
operate at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or dilute the No.
2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the
fuel filters.

microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.
If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
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.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° and 90°F (-12° and 32°C), it will last a
minimum of one year.
DEF is subject to freezing at the lowest temperatures. For
example, DEF may freeze at temperatures at or below
12° F (-11° C). The system has been designed to operate in
this environment.
NOTE: When working with DEF, it is important to know
that:
•
Any containers or parts that come into contact with DEF
must be DEF compatible (plastic or stainless steel). Cop-
per, brass, aluminum, iron or non-stainless steel should be
avoided as they are subject to corrosion by DEF.
• If DEF is spilled, it should be wiped up completely.
