VEHICLE INSPECTION INFORMATION
To be sure your vehicle is ready to operate, conduct a pre-trip inspection
at the beginning of each work period. Follow the steps listed in this
section to ensure a proper vehicle inspection procedure. The pages in
this section may be produced locally and used on a regular basis.
WARNING:Exercise great caution when working on a vehicle
equipped with an automatic fan clutch. The fan starts in motion
only after the engine coolant reaches a predetermined temperature or
the refrigerant pressure (if equipped with air conditioning) reaches a
predetermined setting. The fan starts at this point with no advance
warning. Never reach near, or permit objects to protrude into, the fan
blade radius while the engine is running as this could result in vehicle
damage, personal injury or death.
WARNING:Do not operate the vehicle if any suspension
conditions listed in the following charts are evident. Loss of
steering or suspension could result in property damage, personal injury
or death.
WARNING:If a wheel must be changed, obtain expert tire
service help. Mounting and un-mounting of tires should only be
performed by a qualified technician using necessary safety procedures
and equipment, otherwise the result could be property damage,
personal injury or death.
Note:Always make sure the parking brake is applied before starting the
engine.

Brake ChambersVerify:
•there are no cracks or dents
•they are securely mounted.
Slack AdjusterInspect for broken, loose or missing parts.
Note:The angle between the push rod and
adjuster arm should be approximately 90° when
the brakes are applied. When pulled by hand, the
push rod should not move more than
approximately one inch (2.5 cm).
DrumVerify:
•there are no cracks, dents, holes and no loose
or missing bolts
•the brake linings are not worn, dangerously
thin or contaminated by lubricant.
Rear Wheels
SpacersVerify:
•dual wheels are evenly separated
•the tires are not touching one another.
RimsInspect for damaged or bent rims. Rims should
not have welding repairs, and no rust trails that
indicate it is loose on the wheel.

Trailer
If you are pulling a trailer, an inspection of the trailer similar to that of
the tractor should be done. The inspection should follow trailer
manufacturer recommendations and should include at a minimum:
general condition, landing gear, doors, sides, lights, reflectors,
suspension, brakes, tires, wheels, cargo placement, stability and
tie-downs.
Transmission
WARNING:If the unit starts in gear and/or the neutral start
switch is not functioning correctly, the vehicle may inadvertently
move which could result in property damage, personal injury or death.
If your vehicle is equipped with an automatic transmission, regularly
inspect the transmission’s neutral start switch. The engine should only
start in positionNorP.
Inspect the transmission fluid level and shift linkage for proper
operation.

The differential can be locked or unlocked when the vehicle is moving at
a constant speed of under 25 mph (40 km/h) and while the wheels are
not slipping. The differential must not be locked when the vehicle is
traveling down steep grades and traction is minimal.
The differential lock and differential lock light automatically disengage at
speeds above 25 mph (40 km/h). The differential lock remains off until
either the vehicle is restarted or the differential lock switch is turned off
then back on.
Turn the engine off and raise all drive wheels of the locker differential
axle in order to prevent the vehicle from moving when servicing the
wheels, tires or brakes. Axles equipped with a NoSPIN Detroit Locker
differential deliver power to both wheels even when only one wheel is on
the ground.
WARNING:Failure to raise all drive wheels with this type of
differential could cause the vehicle to move unexpectedly,
resulting in property damage, personal injury or death.
Care should be taken to avoid sudden accelerations when both drive
wheels are on a slippery surface.
WARNING:Sudden accelerations on slippery surfaces could
cause the wheels to spin, the vehicle to turn sideways on a
crowned road surface or in a turn, possibly resulting in loss of vehicle
control and personal injury.
Fluid Temperature
Axle operating temperatures normally do not exceed 100°F (38°C).
If the operating temperature exceeds 230°F (110°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. Extreme Pressure (EP) lubricants should not be run
consistently above 230°F (110°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.

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the rear brakes to
individual wheels and, when needed, reduces engine power at the same
time. If the wheels spin when accelerating on slippery or loose surfaces,
the system reduces engine power in order to increase traction.
Note:The system does not apply the brakes when vehicle speed is
above 25 mph (40 km/h).
USING TRACTION CONTROL
WARNING:Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a traction
control event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
Press the switch to select Off Road
or Mud/Snow traction mode. This is
beneficial when the vehicle is stuck
in snow or on a slippery road
surface. This mode allows excess
wheel spin to dig the vehicle out
and allows you to rock the vehicle.
Press the switch again to select standard traction control. Standard
traction control is automatically selected at the next ignition cycle.

Parking
WARNING:When parking your vehicle, do not leave the
transmission in gear; if the key is in the on position and the
vehicle rolls, the engine could start. Failure to follow these instructions
could result in an unattended vehicle moving, possibly causing personal
injury or property damage.
Always use the parking brake. When parking on a grade, block the
wheels and turn the front wheels to one side so that if the vehicle rolls,
the front tires act against the curb to stop the vehicle. The front wheels
are more effective at stopping a rolling vehicle than the rear wheels.
Cold Weather
Note:Idling in cold weather does not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a build-up of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
Note:The use of winter fronts, or other air-restrictive devices mounted
in front of the radiator on vehicles with chassis-mounted charge air
coolers, are not recommended unless extremely cold weather conditions
exist. Airflow restriction can cause high exhaust temperatures, power
loss, excessive fan usage and a reduction in fuel economy. If you must
use a winter front, the device should have a permanent opening of at
least 120 square inches (774 square centimeters) directly in line with the
fan hub.
For best engine operation in temperatures of 32°F (0°C) or lower:
•Make sure the batteries are the correct type and are fully charged.
Check other electrical components to make sure they are in optimum
condition.
•Use a permanent-type engine coolant to protect the engine against
damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Use the proper engine oil and maintain it at its proper level.
•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.

The upper portion of the switch must be pressed before operating with a
trailer or operating in the bobtail mode.
Suspension 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.
It is not recommended, or approved, that suspension conversions be
performed. However, it is understood that, on occasion, aftermarket
add-on suspensions are installed by others on the truck chassis which
allow operator control for weight transfer from other axles (i.e., air lift
axles).
UPFITTER CONTROLS (IF EQUIPPED)
The upfitter option package
provides four switches, mounted in
the center of the instrument panel.
These switches are always on
whether the engine is running or
not. Make sure you put the switches
in the off position to avoid draining
the battery when the vehicle is not
being used. It is recommended that the engine remain running to
maintain battery charge when using the upfitter switches for extended
duration or higher current draws. (This is even more important for
vehicles with a diesel engine since the glow plugs are also draining
battery power when the ignition key is in the on position.)
Each switch provides 10 amps of electrical battery power for a variety of
personal or commercial uses.
There is also a relay box located on the passenger side end of the
instrument panel. See your authorized dealer for service.
Switch access location is in a connector located in the engine
compartment. More detailed information can be found at
