•The vehicle will only be capable of a maximum speed
of 5 MPH upon the first of the following conditions to
occur:
•If the vehicle is shutoff and restarted.
•If the vehicle is idled for an extended period of time,
approximately one hour or greater.
•If the system detects that the level of fuel in the tank
has increased.
•5 MPH Max Speed Service DEF System See Dealer—
This message will continuously display, and will be
accompanied by a periodic chime. Although the ve-
hicle can be started and placed in gear, the vehicle will
only operate at a maximum speed of 5 MPH. Your
vehicle will require towing, see your authorized dealer
for service.
NOTE:When this message is displayed, the engine can
still be started. However, the vehicle will only operate at
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 displays the message “Ac-
tive 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)

5. After engine start-up, check to see that there is oil
pressure.
6. Allow the engine to idle about three minutes until the
manifold heaters have completed the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
•Engine idle speed will automatically increase to 1,000
RPM and engage the Variable Geometry Turbocharger
at low coolant temperatures to improve engine warm-
up.
•The engine may not automatically crank after the
engineWait To Starttelltale goes off if a door or the
hood is ajar.
•If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start
Light” goes out, reset the grid heaters by turning theignition 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.3. Turn the ignition switch to the ON position and watch
the instrument panel cluster lights.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START the 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.
4. Turn the ignition switch to the START position and
crank the engine. Do not press the accelerator during
starting.

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel filler cap is removed or the
tank filled.
•Never add fuel to the vehicle when the engine is
running.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” Thesemicrobes 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.
