position.Keyless Enter-N-Go Starting Procedure —
Engine Manifold Air Temperature 0° F To
66° F (–18° C to 19° C)
NOTE:
The temperature displayed in the instrument
cluster does not necessarily reflect the en-
gine manifold air temperature. Refer to “In-
strument Cluster Display” in “Getting To
Know Your Instrument Panel” for further in-
formation. 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. Pushing the engine start button with thedriver’s foot on the brake will move the
ignition from OFF or ACC to RUN, and will
illuminate the "Wait To Start" telltale. The
engine will not immediately crank, this is
normal operation.
2. The “Wait To Start" telltale will remain on for a period of time that varies depending
on the engine temperature.
123

3. While the "Wait to Start" telltale is on, theinstrument cluster will additionally dis-
play a gauge or bar whose initial length
represents the full "Wait to Start" time
period. Its length will decrease until it
disappears when the "Wait to Start" time
has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filters to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Dealer
Service” under “Servicing And Mainte-
nance” for further information.
4.
After the engine “Wait To Start” telltale goes
off, the engine will automatically crank.
CAUTION!
Do not crank engine for more than 15 seconds
at a time or starter motor damage may result.
Turn the ignition switch to the OFF position
and wait at least two minutes for the starter to
cool before repeating start procedure.
5. After engine start-up, check to see that there is oil pressure.
6. Allow the engine to idle about three min- utes until the manifold heaters have com-
pleted the post-heat cycle.
7. Release the parking brake and drive.
NOTE:
• Engine idle speed will automatically in- crease to 1,000 RPM and engage the Vari-
able Geometry Turbocharger at low coolant
temperatures to improve engine warm-up.
• The engine may not automatically crank after the engine "Wait To Start" telltale 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 the 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 Proce-
dure – 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 exten-
sion 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.
STARTING AND OPERATING
124

• Warm up the engine before placing it underload.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant weight.
NOTE:
Light duty operation such as light trailer
towing or no load operation will extend the
time before the engine is at full efficiency.
Reduced fuel economy and power may be
seen at this time.
For additional vehicle break-in requirements,
refer to “Trailer Towing” in “Starting And Oper-
ating” of the Owner’s Manual at
www.mopar.com/en-us/care/
owners-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents). Because of the construction of the Cummins
turbocharged diesel engine, engine run-in is
enhanced by loaded operating conditions
which allow the engine parts to achieve final
finish and fit during the first 6,000 miles
(10 000 km).
AUTOMATIC TRANSMISSION
WARNING!
• It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher
than idle speed. If your foot is not firmly
pressing the brake pedal, the vehicle
could accelerate quickly forward or in
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle
could injure those in or near the vehicle.
As with all vehicles, you should never
exit a vehicle while the engine is run-
ning. Before exiting a vehicle, always
come to a complete stop, then apply the

parking brake, shift the transmission
into PARK, turn the engine OFF, and
remove the key fob. When the ignition is
in the LOCK/OFF (key removal) position,
(or, with Keyless Enter-N-Go, when the
ignition is in the OFF mode) the trans-
mission is locked in PARK, securing the
vehicle against unwanted movement.
• When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never use the PARK position as a sub-
stitute for the parking brake. Always
apply the parking brake fully when exit-
ing the vehicle to guard against vehicle
movement and possible injury or dam-
age.
• Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting the vehicle.

your foot is firmly pressing the brake
pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi-
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position. NOTE:
If a malfunction occurs, the system will trap
the key fob in the ignition to warn you that
this safety feature is inoperable. The engine
can be started and stopped but the key fob
cannot be removed until you obtain service.
Brake/Transmission Shift
Interlock System
This vehicle is equipped with a Brake Trans-
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
