Transporting Pets
Air Bags deploying in the front seat could harm
your pet. An unrestrained pet will be thrown
about and possibly injured, or injure a
passenger during panic braking or in a collision.
Pets should be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that
are secured by seat belts.
SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE
CARGO AREA.
Exhaust Gas The best protection against carbon monoxide
entry into the vehicle body is a properly main
-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In addi -
tion, inspect the exhaust system each time the
vehicle is raised for lubrication or oil change.
Replace as required.
WARNING!
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
WARNING! (Continued)
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.

Follow the steps in the “Normal Starting” proce -
dure except:

1. Pushing the ENGINE START/STOP button with the driver’s foot on the brake will
move the ignition from OFF or ACC to RUN, and will illuminate the “Wait To Start” tell
-
tale. 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.
3. While the “Wait to Start” telltale is on, the instrument cluster will additionally display 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.
4. After the engine “Wait To Start” telltale goes off, the engine will automatically crank.
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

224STARTING AND OPERATING
Your vehicle is equipped with an engine warm
up protection feature that may limit engine
performance after cold starting at low ambient
temperatures. The length of time engine speed
is limited is dependent upon engine coolant
temperature. Engine speed may be briefly
limited to 1000 RPM after starting with coolant
temperature below freezing conditions, and
may be limited to 1000 RPM for up to approxi -
mately 2 minutes under more severe cold
conditions.
NOTE:
If ambient temperatures are low and the
coolant temperature is below 180°F (82°C),
the engine idle speed will slowly increase to
1,000 RPM after two minutes of idle, if the
following conditions are met:
Foot is off brake pedal and throttle pedal.
Automatic transmission is in PARK.
Vehicle speed is 0 mph (0 km/h).
Applying the throttle will cancel fast idle.
Operating the exhaust brake at idle will
greatly improve warm up rate and will help
keep the engine close to operating tempera -
ture during extended idle.
Engine Idling
Avoid prolonged idling, long periods of idling
may be harmful to your engine because
combustion chamber temperatures can drop so
low that the fuel may not burn completely.
Incomplete combustion allows carbon and
varnish to form on piston rings, engine valves,
and injector nozzles. Also, the unburned fuel
can enter the crankcase, diluting the oil and
causing rapid wear to the engine.
If the engine is allowed to idle or the truck is
driven on low engine speed drive cycles for
more than 2 hours, the system will automati -
cally enter an emissions operating mode that
will increase the engine idle speed to 900 RPM.
While in this mode, which is designed to help
maintain the diesel particulate filter, the engine
idle speed will return to normal when the brake
pedal is applied. A small change in engine tone
or a slight change in engine performance while
accelerating may also be noticeable at speeds
below 20 mph (32 kmh). This operating mode
may last for up to an hour of idle time, or around
20 minutes of driving time.
Your truck may have been ordered with an
optional voltage monitoring idle up feature. If a
load is placed on the electrical system while the truck is in park, this feature will attempt to
maintain normal system voltage by automati
-
cally increasing engine idle speed. You may
notice several consecutive increases in idle
speed, up to a maximum of 1,450 RPM, as the
system will attempt to utilize the smallest
increase in idle speed necessary to maintain
normal system voltage. The idle speed will
return to normal when either the electrical load
is removed, or when the brake pedal is applied.
NOTE:
For instrument cluster display messages
related to the vehicle's exhaust system, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further infor -
mation.
Idle-Up Feature
The driver-controlled high idle speed feature will
help increase cylinder temperatures and
provide additional cab heat, however, excessive
idling may still cause the exhaust aftertreat -
ment system to not properly regenerate.
Extended periods of idle time should be
avoided.
The Idle-Up feature uses the Speed Control
switches to increase engine idle speed and
quickly warm the vehicle's interior.

20_DJD2_OM_EN_USC_t.book Page 224

STARTING AND OPERATING225

1. With the transmission in PARK, the parking
brake applied, and the engine running,
push the speed control switch to the ON
position, then push the SET switch.

2. The engine RPM will go up to 1,100 RPM. To increase the RPM, push and hold the
ACCEL/RESUME switch and the idle speed
will increase to approximately 1,500 RPM.
To decrease the RPM, push and hold the
DECEL switch and the idle speed will
decrease to approximately 1,100 RPM.
3. To cancel the Idle–Up feature, either push the CANCEL switch, push the ON/OFF
switch, or press the brake pedal.
Noise
Diesel engines can create noises that may
seem concerning. The nature of a diesel engine
is compression ignition where compressed air and fuel are mixed and ignited. Weather, baro
-
metric pressure, altitude, and temperature will
affect how fuel is ignited in the engine. Engines
will sound different from day to day or previous
model years. Clicking, ticking, or light knocking
is normal and will change from day to day, as
the engine breaks in, and can vary with changes
in ambient temperature. Clicking sound from
under the hood shortly after vehicle shutdown is
normal as actuators such as the EGR valve are
cycled. Fuel pump noise may increase during
low speed/light load conditions when ambient
temperature is above 100°F (38°C), and when
fuel tank level is below 10% which is a normal
condition of the fuel system and controls
strategy. Diesel equipped vehicles also have an
exhaust after-treatment system to reduce emis -
sions utilizing a DPF (refer to “Odor” in this
section for further information) and a Selective
Reduction Catalyst (SCR). The SCR reduces
Nitrogen Oxides (NOx) using the Diesel Exhaust Fluid (DEF) system. DEF is injected directly into
the SCR through a dosing module. This process
will create a clicking sound and at times, will
make noise even with the vehicle shut off. This
is normal as the DEF dosing module is purging
DEF. If at any time the check engine light is on,
please visit an authorized dealer.
Stopping The Engine
Idle the engine a few minutes before routine
shutdown. After full load operation, idle the
engine three to five minutes before shutting it
down. This idle period will allow the lubricating
oil and coolant to carry excess heat away from
the combustion chamber, bearings, internal
components, and turbocharger. This is espe
-
cially important for turbocharged, charge
air-cooled engines. Refer to the following chart
for proper engine shutdown:
Driving Condition Load Turbocharger Temperature Idle Time (min.) Before Engine
Shutdown

NOTE:
For optimum braking power it is recommended
to use the exhaust brake while in TOW/HAUL
mode.
The exhaust brake feature can also be used to
reduce the engine warm up time. To use the
exhaust brake as a warm-up device, the vehicle
must be stopped or moving less than 5 mph
(8 km/h), the "Exhaust Brake Indicator" must be
on, and the coolant temperature must be below
180°F (82°C) and ambient temperature below
60°F (16°C).
Automatic “Smart” Exhaust Brake
Automatic “Smart” Exhaust Brake technology
delivers smoother, less aggressive exhaust
braking characteristics during downhill
descents. Although it can apply full exhaust
braking force if needed, Automatic “Smart”
Exhaust Brake may not apply obvious braking if
the vehicle speed is not increasing. Automatic
“Smart” Exhaust Brake is intended to maintain
vehicle speed, while Full Exhaust Brake is
intended to reduce vehicle speed. Automatic “Smart” Exhaust Brake can be
enabled by pushing the exhaust brake button
(on the center stack) again anytime after the
normal Full Exhaust Brake has been turned on.
The “Exhaust Brake Indicator” in the instrument
cluster display will change from Yellow to Green
when Automatic “Smart” Exhaust Brake is
enabled. Pushing the exhaust brake button
again will toggle the exhaust brake mode to off.
AUTOMATIC TRANSMISSION
WARNING!
Never use the PARK position as a substi
-
tute for the parking brake. Always apply the
parking brake fully when exiting the vehicle
to guard against vehicle movement and
possible injury or damage.
Your vehicle could move and injure you and
others if it is not in PARK. Check by trying to
move the transmission gear selector out of
PARK with the brake pedal released. Make
sure the transmission is in PARK before
exiting the vehicle.
The transmission may not engage PARK if
the vehicle is moving. Always bring the
vehicle to a complete stop before shifting to
PARK, and verify that the transmission gear
position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is
completely stopped, and the PARK position
is properly indicated, before exiting the
vehicle.
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 accel -
erate 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.

266STARTING AND OPERATING
(Continued)
Fairlead: The hawse fairlead acts as a guide for
the synthetic rope and minimizes damage to the
rope.
Winch Accessories
The following accessories are necessary to
attach the winch to anchors, change direction of
pull, and for safe winching.
Gloves: It is extremely important to
wear protective gloves while oper -
ating the winch or handling the winch
rope. Avoid loose fitting clothes or
anything that could become entangled in the
rope and other moving parts.
Snatch/Block Pulley: Used properly,
the multi-purpose snatch block allows
you to (1) increase the winch's pulling
power; and (2) change your pulling
direction without damaging the winch rope.
Proper use of the snatch block is covered in
"Before You Pull." Clevis/D-Shackles:
The D-Shackle is
a safe means of connecting the
looped ends of cables, straps and
snatch blocks. The shackle's pin is
threaded to allow easy removal.
Tree Trunk Protector: Typically made
of tough, high-quality nylon, it
provides the operator an attachment
point for the winch rope to a wide
variety of anchor points and objects, as well as
protect living trees.
Abrasion Sleeve: The abrasion sleeve is
provided with the synthetic rope and must be
used with the synthetic rope at all times to
protect the rope from potential abrasion wear.
The sleeve has a loose fit so it can easily be
positioned along the synthetic rope to protect
from rough surfaces and sharp corners.
Operating Your Winch CAUTION!
If not installed, the hook strap must be
placed on the hook.WARNING!
Failure to observe any of these warnings
regarding proper winch usage may result in
severe injury.
Always use supplied hook strap to hold the
hook when spooling wire rope in or out.
Never use as a hoist.
Never use to move persons.
Never exceed winch or synthetic rope rated
capacity.
Always wear heavy leather gloves when
handling the synthetic rope.
Never touch synthetic rope or hook while in
tension or under load.
Never engage or disengage clutch if winch
is under load, synthetic rope is in tension,
or rope drum is moving.
Always stand clear of synthetic rope and
load and keep others away during winching.

20_DJD2_OM_EN_USC_t.book Page 266

272STARTING AND OPERATING
NOTE:
How to spool under no load: Arrange the remote
control lead so it cannot be caught in the winch.
Arrange the synthetic rope so it will not kink or
tangle when spooled. Be sure any synthetic
rope already on the spooling drum is wound
tightly and evenly layered. Tighten and
straighten the layer if necessary. Keep the
synthetic rope under light tension and spool the
rope back and onto the winch drum in even
layers. Stop frequently to tighten and straighten
the layers as necessary. Repeat this process
until the winch hook is the same distance as the
full length of the remote control from the winch.
Pinch the hook between your thumb and fore -
finger and attach the hook strap. Hold the hook
strap between the thumb and forefinger to keep
tension on the synthetic rope. Walk the
synthetic rope towards the fairlead, carefully
spooling in the remaining rope by pulsing the
remote control switch.
18. Store the hook on the most outboard loop of the hawse fairlead.
Hook In Stored Position

19. Disconnect the remote control. Disconnect the remote control cord from the control box
and store in a clean and dry place. Winching
operations are now complete. Put the cap
on the solenoid plug-in.
NOTE:
Always store the remote control in a protected,
clean, dry area.
Rigging Techniques
Various winching situations will require applica-
tion of other winching techniques. These could
range from too little distance to achieve
maximum pull using straight line rigging, simply
increasing pulling power, or maintaining a
straight-line pulling situation. You will have to assess what technique is correct for your situa
-
tion. Think "safety" at all times.
How To Change The Pulling Direction

Change Pulling Directions

All winching operations should have a straight
line from the winch to the object being pulled.
This minimizes the synthetic rope collecting on
one side of the drum affecting pulling efficiency
and damaging synthetic rope. A snatch block,
secured to a point directly in front of the vehicle
will enable you to change your pulling direction
while still allowing the synthetic rope to be at
90° to wind properly onto the spooling drum.

20_DJD2_OM_EN_USC_t.book Page 272

STARTING AND OPERATING281

Distance Setting 4 Bars (Longest)
Distance Setting 3 Bars (Long) Distance Setting 2 Bars (Medium)
Distance Setting 1 Bar (Short)

The system automatically defaults to the
longest distance setting. To decrease the
distance setting, push the Distance Button and
release. Each time the button is pushed, the
distance setting decreases by one bar. Once the
shortest setting is reached, if the button is pushed again it will reset to the default setting
(longest).
If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the instru
-
ment cluster displays the ACC Set With Target
Indicator Light, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to “Activating
Adaptive Cruise Control (ACC)” in this
chapter.
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.

STARTING AND OPERATING301

Lane Crossed (Flashing Yellow Lane Line) With Yellow
Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure when only
the right lane marking has been detected.
Left Lane Departure — Both Lane Lines
Detected
When the LaneSense system is on and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs. The lane lines
turn from gray to white and the LaneSense
telltale is solid green.
Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Approached (Solid Yellow Lane Line) With Solid
Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left lane line flashes yellow
(on/off). The LaneSense telltale changes
from solid yellow to flashing yellow. At this
time torque is applied to the steering wheel in
the opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.5
