NOTE:If the ignition switch is left in the ACC or RUN
(engine not running) position and the transmission is in
PARK, the system will automatically time out after 30
minutes of inactivity and the ignition will switch to the
OFF position.
ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN.
To change the ignition switch positions without starting
the vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Press the ENGINE START/STOP button once to change the ignition to the ACC position. 3. Press the ENGINE START/STOP button a second time
to change the ignition to the RUN position.
4. Press the ENGINE START/STOP button a third time to return the ignition to the OFF 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 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. Pushing the engine start button with the driver ’s footon the brake will move the ignition from OFF or ACC
to RUN, and will illuminate the Wait To Starttelltale.
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 tempera-
ture.
3. 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.
4. After the engine “Wait To Start” telltale goes off, the engine will automatically crank.
CAUTION!
The engine may automatically crank when the “Wait
To Start” time has elapsed. To abort the automatic
starting process, ensure the driver ’s foot is fully
removed from the brake pedal prior to pushing the
START/STOP button to cycle the ignition off.

5. After engine start-up, check to see that there is oilpressure.
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
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 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.

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. When the engine starts, release the key fob.
6. Check that the oil pressure warning light has turned off.
7. Release the parking brake.

WARNING!(Continued)
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be
seriously or fatally injured. Children should be
warned not to touch the parking brake, brake pedal
or the transmission gear selector. Do not leave the
key fob in or near the vehicle (or in a location
accessible to children), and do not leave the igni-
tion (of a vehicle equipped with Keyless Enter-N-
Go™) in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move
the vehicle.
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the engine is operating.
• All message center lights are off.
• Malfunction Indicator Light (MIL) is off.
• Engine oil pressure is above 10 psi (69 kPa) at idle.
• Voltmeter operation:
The voltmeter may show a gauge fluctuation at various
engine temperatures. This cycling operation is caused by
the post-heat cycle of the intake manifold heater system.
The number of cycles and the length of the cycling
operation is controlled by the engine control module.
Post-heat operation can run for several minutes, and then
the electrical system and voltmeter needle will stabilize.
The cycling action will cause temporary dimming of the
headlamps, interior lamps, and also a noticeable reduc-
tion in blower motor speed.

JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
• Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e., do
not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
