•Automatic equipped vehicles with optional Keyless
Enter-N-Go™ – If the start button is pushed once
while in park with the ignition off and driver ’s foot on
the brake pedal, the vehicle will automatically crank
and start after the Wait to Start time has elapsed. If it is
desired to abort the start process before it completes,
the driver ’s foot should be fully removed from the
brake pedal prior to pushing the start button again in
order for the ignition to move directly to off.
•If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale 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 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”Starting Procedure — Engine Manifold Air
Temperature Below 0°F (-18°C)
In extremely cold weather below 0°F (-18°C) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF for at least five seconds and
then back ON after the “Wait To Start” telltale has turned
off, but before the engine is started. However, excessive
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
NOTE:If multiple pre-heat cycles are used before start-
ing, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
1. If the engine stalls after the initial start, the ignition
must be turned to the OFF position for at least five
seconds and then to the ON position to recycle the
manifold heaters.

NOTE:Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
2. Heat generated by the manifold heaters dissipates
rapidly in a cold engine. If more than two minutes
pass between the time the “Wait To Start” telltale turns
off and the engine is started, recycle the manifold
heaters by turning the ignition switch to the OFF
position for at least five seconds and then back ON.
3. If the vehicle is driven and vehicle speed exceeds
19 mph (31 km/h) before the manifold heater post-
heat (after start) cycle is complete, the manifold heat-
ers will shut off.
4. If the engine is started before the “Wait To Start”
telltale turns off, the preheat cycle will turn off.
5. If the engine is cranked for more than 10 seconds, the
post-heat cycle will turn off.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.
•When a diesel engine is allowed to run out of fuel or
the fuel gels at low temperatures, air is pulled into the
fuel system. If your engine has run out of fuel, refer to
“Maintenance Procedures/Priming If The Engine Has
Run Out Of Fuel” in “Maintaining Your Vehicle” for
further information.
•If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale 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 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”

Starting Fluids
WARNING!
Starting fluids or flammable liquids must never be
used in the Cummins® diesel engine (see Warning
label). Never pour diesel fuel, flammable liquid, start-
ing fluids (ether) into the air cleaner canister, air intake
piping, or turbocharger inlet in an attempt to start the
vehicle. This could result in a flash fire and explosion
causing serious personal injury and engine damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
•When leaving the vehicle, always make sure the
ignition is in the OFF position, remove the key fob
from the vehicle, and lock the vehicle.
•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

must turn the ignition switch from the LOCK/OFF
position to the ON/RUN position, and also press
the brake pedal. Otherwise, damage to the shift
lever could result.
•DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as this
can damage the drivetrain.The following indicators should be used to ensure that
you have engaged the transmission into the PARK posi-
tion:
•When shifting into PARK, pull the shift lever toward
you and move it all the way counterclockwise until it
stops.
•Release the shift lever and make sure it is fully seated
in the PARK gate.
•Look at the transmission gear position display and
verify that it indicates the PARK position.
•With brake pedal released, verify that the shift lever
will not move out of PARK.

NEUTRAL (N)
Use this range when the vehicle is standing for prolonged
periods with the engine running. The engine may be
started in this range. Apply the parking brake and shift
the transmission into PARK if you must leave the vehicle.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe
practices that limit your response to changing traffic
or road conditions. You might lose control of the
vehicle and have a collision.

severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In Emergencies”
for further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through underdrive first, second,
and third gears, direct fourth gear and overdrive fifth and
sixth gears. The DRIVE position provides optimum driv-
ing characteristics under all normal operating conditions.
