VEHICLE INSPECTION INFORMATION
To make 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 verify a proper vehicle inspection procedure.
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 you apply the parking brake before starting the
engine.

D.A/C:Press to turn air conditioning on or off. Air conditioning cools
the vehicle using outside air. To improve air conditioning when starting
your vehicle, drive with the windows slightly open for two to three
minutes.
E.Recirculated air:Press to switch between outside air and
recirculated air. When the LED on the button is lit, the air currently in
the passenger compartment is being recirculated. Using recirculated air
can reduce the time needed to cool the interior and reduce unwanted
odors from entering your vehicle.
Note:For better cooling in hot conditions, recirculated air automatically
engages when the air distribution control is in Panel or Panel/Floor
modes and the air conditioning is on. You can switch to fresh air by
pressing the recirculated air button again.
F.MAX A/C:Distributes recirculated air through the instrument panel
vents to cool the vehicle. This position is more economical and efficient
than normal A/C.
G.Temperature control:Controls the temperature of the air circulated
in your vehicle. Turn to select the desired temperature.
H.Fan speed control:Controls the volume of air circulated in your
vehicle. Turn to select the desired fan speed or switch off. If you switch
the fan off, the windshield may fog up.
I.Power:Press to turn the system on and off. When the system is off,
outside air is prevented from entering the vehicle.
GENERAL OPERATING TIPS
•To reduce fog build-up on the windshield during humid weather,
select Defrost. Temperature and fan speed can also be increased to
improve clearing.
•To reduce humidity build-up inside the vehicle, do not drive with the
system off or with recirculated air engaged.
•Do not put objects under the front seats that interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base
of the windshield.
Cooling the interior quickly:
1. Adjust the fan speed to the highest speed setting initially and then
adjust it to suit the desired comfort level.
2. Adjust the temperature control to the lowest temperature setting.
3. Adjust the air distribution control to the MAX A/C position.
Climate Control77

Recommended settings for cooling:
•Adjust the air distribution control to the A/C position.
If your vehicle is stationary for extended periods during extreme high
ambient temperatures:
•Select the MAX A/C position.
Gas engines:If your vehicle is stationary for long periods of time in
high ambient temperature conditions, your climate control system may
automatically switch from fresh air mode to recirculation mode. This is
normal system operation as it provides protection of the air conditioning
compressor (and related parts). It is recommended that you allow the
system to remain in this mode if it has switched. The system reverts
back to fresh air mode when conditions allow.
For maximum cooling performance, turn the air distribution control to
MAX A/C.
To aid in side window defogging/demisting in cold weather:
1. Select Panel/Floor.
2. Select A/C.
3. Adjust the temperature control to maintain comfort.
4. Set the fan speed to the highest setting.
5. Direct the outer instrument panel vents toward the side windows.
6. To increase airflow to the outer instrument panel vents, close the
vents located in the middle of the instrument panel.
HEATED MIRRORS (IF EQUIPPED)
Note:Do not remove ice from the mirrors with a scraper or attempt to
readjust the mirror glass if it is frozen in place. These actions could
cause damage to the glass and mirrors.
Note:Do not clean the housing or glass of any mirror with harsh
abrasives, fuel or other petroleum-based cleaning products.
Both mirrors are heated to remove ice, mist and fog when the heated
mirror button is pressed.

•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.
Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, air
conditioning condenser and accessories clean to avoid dirt build-up.
•You may experience above normal coolant temperatures while driving
in a transmission gear ratio that lugs the engine. To correct this
problem, increase engine speed by downshifting into the next lower
gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering your vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate your vehicle with the power steering pump fluid level
below the ADD mark on the MAX COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by an authorized dealer.
•Low power steering pump fluid levels may cause heavy or uneven
steering efforts. Check the power steering pump fluid level before
seeking service from an authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX HOT side of the power steering reservoir dipstick, as this
may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer your vehicle manually, but it takes more effort.
Driving Aids161

•Place the gearshift lever in positionP(if equipped) or neutral to aid
in engine and transmission cooling and air conditioning efficiency
during hot weather while stopped in traffic.
•Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
•Shift to a lower gear when driving down a long or steep hill. Do not
apply the brakes continuously, as they may overheat and become less
effective.
•Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
FIFTH WHEEL OPERATION
WARNING:Failure to follow the fifth wheel manufacturer’s
instructions for hooking and unhooking as well as sliding the fifth
wheel could result in an accident, personal injury or death.
WARNING:When the tractor and trailer are parked unattended,
the trailer brake hand control should never be used to apply the
brake, since air may leak from the system, allowing vehicle movement,
resulting in possible property damage, personal injury or death.
Before hook-up, make sure:
•The fifth wheel jaws are fully open.
•The fifth wheel is fully tilted back to prevent body damage when the
tractor is backed under a trailer.
•You block the trailer wheels and adjust and apply the trailer spring
brakes. Never chase a trailer.
•The brake hoses and light cords are clear of the fifth wheel.
Hook-up
1. Back the tractor squarely under the trailer, engaging the fifth-wheel
jaws on the kingpin. Always back up slowly; make sure the trailer is
neither too high nor too low. Avoid backing under the trailer from an
angle.
2. Connect the service and emergency brake hoses and trailer light
connector.
3. Inspect the jaws of the fifth wheel to be sure they have fully closed
on the trailer kingpin and the trailer plate is resting securely on the
fifth wheel.

Climate Control System
Have the air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to system performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for things such as
dirt and lint. Replace the filter if necessary. Vehicles operating in
unusually dusty conditions may require more frequent filter inspection
and replacement.
Front Axle
Maintaining the front axle alignment to specifications is very important.
A qualified technician should check and maintain the alignment. Regular
inspections should include:
•Toe-in inspection and adjustment (if necessary), particularly with
radial tires.
•Checking for proper tightness of axle mounting U-bolt nuts, attaching
or mounting bolts and nuts.
•Checking the axle for damage, binding, worn parts and adequate
lubrication..
•Checking the kingpins for excessive wear. Also, perform this check
during other scheduled maintenance (such as tire rotation or service,
wheel bearing service and alignment). See the workshop manual for
proper procedures.
Toe-in
It is essential to maintain correct toe-in and tire pressure for optimum
tire wear.
Inspecting steer axle tires in the first 3000–10000 service miles
(5000–16000 service kilometers) generally shows if tires are wearing
normally.
Rapid outside shoulder wear on both tires indicates too much toe-in.
Rapid inside shoulder wear on both tires indicates too much toe-out.
In P&D-type service, there can be a left-to-right steer tire tread life
differential up to 40% depending on routes and other variables.
Follow the tire manufacturer’s recommended cold inflation pressure for
the tire size, load range (ply rating) and steer axle loading typical for
their operation (each steer axle tire equals
12steer axle loading).

4. Allow the engine to idle for at least one minute.
5. Turn on the air conditioning and allow the engine to idle for at least
one minute.
6. Release the parking brake. With your foot on the brake pedal and
with the air conditioning on, put the transmission in positionP
(automatic transmission) or neutral (manual transmission) and allow
the engine to idle for at least one minute.Note:Not allowing the
engine to relearn the idle trim may adversely affect the idle quality of
your vehicle until the engine eventually relearns the idle trim.
7. Drive your vehicle to complete the relearning process.
If you disconnect the battery or install a new battery, you have to reset
the clock and radio settings after reconnecting the battery.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center to
find out more about recycling
automotive batteries.
CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
