SITTING IN THE CORRECT
POSITION
WARNINGS
Do not recline the seatback as this
can cause the occupant to slide
under the safety belt, resulting in
serious injury in the event of a crash. Do not place objects higher than the
seatback to reduce the risk of serious
injury in the event of a crash or during
heavy braking. When you use them properly, the seat,
head restraint, safety belt and airbags will
provide optimum protection in the event
of a crash.
We recommend that you follow these
guidelines:
•
Sit in an upright position with the base
of your spine as far back as possible.
• Do not recline the seatback more than
30 degrees.
• Adjust the head restraint so that the
top of it is level with the top of your
head and as far forward as possible.
Make sure that you remain
comfortable. •
Keep sufficient distance between
yourself and the steering wheel. We
recommend a minimum of 10 in
(25 cm) between your breastbone and
the airbag cover.
• Hold the steering wheel with your arms
slightly bent.
• Bend your legs slightly so that you can
press the pedals fully.
• Position the shoulder strap of the
safety belt over the center of your
shoulder and position the lap strap
tightly across your hips.
Make sure that your driving position is
comfortable and that you can maintain full
control of your vehicle.
HEAD RESTRAINTS WARNINGS
Fully adjust the head restraint before
you sit in or operate your vehicle. This
will help minimize the risk of neck
injury in the event of a crash. Do not adjust
the head restraint when your vehicle is
moving. The head restraint is a safety device.
Whenever possible it should be
installed and properly adjusted when
the seat is occupied. An improperly
adjusted head restraint may not
adequately protect an occupant during an
impact from the rear. Install the head restraint properly to
help minimize the risk of neck injury
in the event of a crash.

STARTING A GASOLINE
ENGINE
When you start the engine, the idle speed
increases, this helps to warm up the
engine. If the engine idle speed does not
slow down automatically, have your
vehicle checked by an authorized dealer.
Before starting the engine check the
following:
•
Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P) or neutral (N).
• Turn the ignition key to the on position.
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to the start position to start the engine. Release the key when
the engine starts.
Note: The engine may continue cranking
for up to 15 seconds or until it starts.
Note: If you cannot start the engine on the
first try, wait for a short period and try again.
Failure to Start
If you cannot start the engine after three
attempts, wait 10 seconds and follow this
procedure:
1. Fully press the brake pedal.
2. Fully press the accelerator pedal and hold it there.
3. Start the engine.
Stopping the Engine When Your
Vehicle is Stationary
1. Shift into park (P) or neutral (N). 2. Turn the key to the off position.
3. Apply the parking brake.
Stopping the Engine When Your
Vehicle is Moving WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance.
The steering will not lock, but higher effort
will be required. When the ignition is
switched off, some electrical circuits,
including air bags, warning lamps and
indicators may also be off. If the ignition
was turned off accidentally, you can shift
into neutral (N) and re-start the engine. 1. Put the transmission into neutral (N)
and use the brakes to bring your vehicle
to a safe stop.
2. When your vehicle has stopped, shift into park (P) or neutral (N) and switch
the ignition off.
3. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the

Operator Commanded Regeneration
Precautions and Safe Exhaust Position
WARNING
Failure to comply with the following
instructions for Operator
Commanded Regeneration may
result in fire, serious injury, death or
property damage. Before you start operator commanded
regeneration, do the following:
•
Place your vehicle in Park (P) with the
parking brake set on stable, level
ground.
• You must park your vehicle outside of
any structure.
• Your vehicle must be 10– 15 feet (3–5
meters) away from any obstructions
and must be away from materials that
can easily combust or melt (for
example, paper, leaves, petroleum
products, fuels, plastics and other dry
organic material). •
Make sure there is a minimum of 1/8
tank of fuel.
• Make sure all fluids are at proper levels.
How to Start Operator Commanded
Regeneration WARNING
Stay clear of exhaust tip during
regeneration. You or others can be
burned.
Note:
You cannot use the Operator
Commanded Regeneration until the diesel
particulate filter load percentage has
reached 100% (Full). The diesel particulate
filter load percentage fluctuates up and
down when driving your vehicle due to active
and passive regenerations.
Note: During the use of Operator
Commanded Regeneration, you may
observe a light amount of white smoke. This
is normal. You cannot use the Operator
Commanded Regeneration if the
service engine soon light is
illuminated.

How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the Operator
Commanded Regeneration, pressing the
brake, accelerator, or shutting off the
vehicle stops the procedure. Depending on
the amount of time you allowed the
Operator Commanded Regeneration to
operate, soot may not have had sufficient
time to be eliminated, but the exhaust
system and exhaust gas may still be hot.
If you shut your vehicle off during Operator
Commanded Regeneration, you will notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal. Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be removed
for ash cleaning at approximately 120,000
miles (193,000 km) or greater (actual
mileage can vary greatly depending upon
engine/vehicle operating conditions) and
replaced with a new or remanufactured
(ash cleaned) part. The filter may need to
be replaced at approximately 250,000
miles (400,000 km) depending upon
vehicle operating conditions.
In both cases, the engine control
system illuminates a service light
to inform you that your vehicle
requires service.
If there are any issues with the diesel
particulate filter system, the engine control
system illuminates a service light to inform
you that your vehicle requires service.

Brake-Shift Interlock (If Equipped)
WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
When doing this procedure, you will
be taking your vehicle out of park
which means your vehicle can roll
freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheel chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is in the 3 (on) position
and the brake pedal is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition in the
4 (on) position and the brake pedal
pressed, a malfunction may have occurred.
It is possible that a fuse has blown or your
vehicle
’s brake lamps are not operating
properly. See
Fuse Specification Chart
(page 162).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 (off), then remove the
key.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).
3. Remove the gearshift lever boot. 4. Place fingers into hole where you
removed the gearshift lever boot and
pull top half of shroud up and forward
to separate it from the lower half of the
shroud. There is a hinge at the forward
edge of the top shroud. Roll the top
half of the shroud upward on the hinge
point to clear the hazard flasher button,
then pull straight rearward toward the
driver ’s seat to remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under the column that secure the lower shroud
half to the column. 7.
Pull the lock lever into the full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover.
8. Apply the brake. Gently lift the override
disk and move the gearshift lever into
neutral (N).

GENERAL INFORMATION
WARNING
Exceeding these ratings by
overloading can cause component
failure resulting in property damage,
personal injury or death. Fluid Temperature
If the operating temperature exceeds
250°F (121°C), the rate of axle lubrication
oxidation increases and shortens the life
of the lubricant and seals, requiring axle
lubrication changes to become more
frequent to preserve the axle. Do not
consistently run extreme pressure (EP)
lubricants above
250°F (121°C).
Axle Conversions WARNING
When operating a loaded vehicle, the
driver must keep all adjustable axles
on the ground at all times, supporting
their share of the vehicle ’s load. Failure to
do so can overload other axles, tires,
wheels, springs, steering components,
brakes and frames, resulting in early
component failure, loss of vehicle control,
possible property damage and personal
injury. We do not recommend, or approve,
performing axle conversions. However, we
understand that, on occasion, others install
aftermarket add-on axles on the truck
chassis that allow operator control for
weight transfer from other axles (such as
air lift axles). LIMITED SLIP DIFFERENTIAL WARNING
If both wheels are not raised off the
ground, the one wheel that is not
raised may pull the vehicle off its
support, possibly resulting in personal
injury. This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
Both wheels must be raised off the ground
should it be necessary to operate one
wheel with your vehicle stationary.
ELECTRONIC LOCKING
DIFFERENTIAL
Driver-Controlled Locking
Differential
Note:
Never use the differential lock at
vehicle speeds above
25 mph (40 km/h).
Some drive axles have a driver-controlled
differential lock. The differential lock can
lock or unlock the differential when your
vehicle is moving or stopped. When extra
traction is required, the differential lock
provides full power to both wheels.
When you lock the differential, your
vehicle ’s turning radius increases
(under-steer).
Take care to avoid sudden accelerations
when both drive wheels are on a slippery
surface.

GENERAL INFORMATION
WARNINGS
Do not drive with your foot resting on
the brake pedal. This results in
abnormally high brake temperatures,
excessive lining wear and increased
stopping distance. Continuous application of the brakes
causes the brakes to overheat,
resulting in temporary loss of braking.
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
All standard equipment brakes are
self-adjusting. Automatic adjustment,
when required, occurs whenever you apply
and release the brakes during forward or
reverse operation.
Know the required stopping distances for
all driving conditions you may encounter.
For longer brake lining life, take full
advantage of engine braking power when
coming to a stop. See Warning Lamps and
Indicators (page 58).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes.
If brakes do not grip well:
• Check brake adjustment.
• Check brake linings for excessive wear.
• Check system air pressure on vehicle
equipped with air brakes. •
Let the brakes cool if you have been
using them excessively, as in mountain
driving or after several fast, high-speed
stops.
• If you have been driving through deep
water, gently apply the brakes several
times while your vehicle is moving
slowly.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the system is disabled, normal
braking is still effective. If the
brake warning lamp illuminates
when you release the parking brake, have
the system checked by an authorized
dealer. If you connect a PLC trailer with
the ignition on, the trailer ABS
light also illuminates. If the light
fails to illuminate, if it remains on after you
start the vehicle or continues to flash, have
the system serviced immediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.

PRINCIPLE OF OPERATION
Cruise control lets you maintain a set
speed without keeping your foot on the
accelerator pedal. You can use cruise
control when your vehicle speed is greater
than 20 mph (30 km/h).
USING CRUISE CONTROL WARNINGS
Do not use cruise control on winding
roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not
apply the brakes but a warning displays.
Failure to follow this warning could result
in serious personal injury or death. Note:
Cruise control will disengage if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed while driving
uphill. The cruise controls are on the steering
wheel.
