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
your vehicle rolls, the front tires act against
the curb to stop your vehicle. The front
wheels are more effective at stopping a
rolling vehicle than the rear wheels.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size. •
Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first
5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.

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. Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operating
range. See
Engine Oil Dipstick (page 192).
Engine oil
Look through the plastic reservoir and verify the coolant level
is within the proper operating range. Do not remove the
pressure cap until the coolant has cooled. See
Engine
Coolant Check (page 200).
Engine coolant
Verify that the fluid level is in the proper operating range. See
Power Steering Fluid Check
(page 206).
Power steering fluid
Remove the master cylinder caps and inspect the fluid level.
See
Brake Fluid Check (page 205).

F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Vehicle Inspection Guide

Rear brakes
Inspect for cracked, worn or frayed hoses, and that all coup-
lings are secure.
Hoses
Verify that there are no cracks or dents, and that the cham-
bers are securely mounted.
Brake chambers
Inspect for broken, loose or missing parts.
Slack adjusters
Note: The angle between the push rod and adjuster arm
should be approximately 90 degrees when the brakes are
applied. When pulled by hand, the push rod should not move
more than approximately
1 in (2.5 cm).
Verify that there are no cracks, dents, holes, and no loose or
missing bolts and that the brake linings are not worn,
dangerously thin or contaminated by lubricant.
Drums Rear wheels
Check for even separation of dual wheels, and that the tires
are not touching each other.
Spacers
Inspect for damaged or bent rims. They should not have
welding repairs, and there should be no rust trails, which
indicate it is loose on the wheel.
Rims
Verify all lug nuts are present and not loose (look for rust
trails around the lug nuts). There should be no cracks radiating
from the lug bolt holes or distortion of the bolt holes.
Lug nuts
Trailer
If you are pulling a trailer, perform an
inspection of the trailer similar to that of
the tractor. 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.
Regularly inspect the transmission's
neutral start switch. The engine should
only start in neutral (N) or park (P) (if
equipped with a park position).
185
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Vehicle Inspection Guide

Regular inspections should include:
•
Checking the brake lining (every service
interval). Establish inspection intervals
that provide for lining replacement
before damage to the disc occurs.
Excessive lining wear may expose the
backing plate to the disc causing
scoring of the disc faces. A qualified
technician should perform this
inspection and keep to instructions
provided by the service manual.
Hydraulic brake systems are
power-assisted. There is a great
reduction in braking capabilities
without engine assist.
• Proper fluid level. The level should be
at the bottom edge of the ring on each
reservoir fill port. Do not fill the master
cylinder to the top of the reservoir. If
fluid level requires attention to
maintain a proper master cylinder level,
this is an indication of either severe
operation (pad wear) or fluid leakage.
A more frequent and thorough brake
inspection is required.
• Brake lines, hoses and fittings. Repair
or replace brake line tubes, hoses or
fittings as required. Inspect these
components every 4,000 mi
(6,000 km) for the following.
• Lines for kinks, dents, corrosion or
rupture.
• Hoses for abrasions, kinks, soft
spots or rupture, collapse, cracks,
twists or loose frame supports.
When replacing a hose, be sure
there is adequate clearance to the
hose to avoid an abrasion to the
new hose.
• All connections for leaks. Driveline Parking Brake WARNING:
Use wheel chocks and
exercise caution when inspecting under
the vehicle. A vehicle roll-away could
result in property damage, personal injury
or death.
A qualified technician should adjust the
parking brake and keep to the instructions
in the service manual.
AXLE INSPECTION
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, for
example 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.
225
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Maintenance

Inspecting steer axle tires in the first
3,000–
10,000 mi (5,000– 16,000 km)
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 ½ steer axle
loading).
Special applications may warrant a setting
based on experience with the type of tire
operating loads and conditions. Radial tires
are more sensitive to toe-in setting than
bias ply tires. Fine tuning school bus
alignment to line-haul truck standards
does not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION WARNING: Failure to maintain the
steering system in proper condition can
cause reduced steering ability resulting
in property damage, personal injury or
death.
Note: Have any steering problems
immediately corrected by a qualified service
technician.
Ask your service technician to examine the
steering mechanism. Only minor
adjustments may be necessary. Regular inspections should include:
•
Checking the tie rod, drag link end
clamp bolts and ball joints for proper
tightness.
• Checking for installation and spread of
cotter pins and tightness of nuts at
both ends of the tie rod and drag link.
• Checking that the pitman arm (steering
arm at steering gear) mounting is tight
and locked. Check system for leaks or
hose chafing. Repair immediately, if
necessary.
• Maintaining proper steering gear and
power steering pump lubricant levels.
• Checking steering column joint bolts
and steering linkage, particularly for
body-to-chassis clearance.
Steering Column Joint Bolts
As a good maintenance practice, check
steering column joint bolt tightness every
60,000 mi (96,000 km) or annually,
whichever occurs first. Do not overtighten
the bolts.
Hydraulic System
Whenever draining and refilling the power
steering's hydraulic system for any reason,
bleed air from the system before returning
the vehicle to service. Failure to bleed the
hydraulic system properly can result in
degradation of power system performance.
Consult an authorized dealer who is aware
of the proper procedures for filling and
bleeding the system.

• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration. •
Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have
any concerns or issues.

TIRE CARE
Glossary of Tire Terminology
*Tire label: A label showing the
original equipment tire sizes,
recommended inflation pressure
and the maximum weight the
vehicle can carry.
*
Tire Identification Number: A
number on the sidewall of each
tire providing information about
the tire brand and manufacturing
plant, tire size and date of
manufacture. Also referred to as
DOT code.
*
Inflation pressure: A measure
of the amount of air in a tire.
*
Standard load: A class of
P-metric or Metric tires designed
to carry a maximum load at set
pressure. For example: For
P-metric tires 35 psi (241 kPa) and
for Metric tires
36 psi (248 kPa).
Increasing the inflation pressure
beyond this pressure does not
increase the tire ’s load carrying
capability.
*
Extra load: A class of P-metric
or Metric tires designed to carry a
heavier maximum load at
42 psi
(290 kPa). Increasing the inflation
pressure beyond this pressure
does not increase the tire ’s load
carrying capability.
*
kPa: Kilopascal, a metric unit of
air pressure.
*
PSI: Pounds per square inch, a
standard unit of air pressure. *
Cold tire pressure: The tire
pressure when the vehicle has
been stationary and out of direct
sunlight for an hour or more and
prior to the vehicle being driven for
1 mi (1.6 km)
.
*
Recommended inflation
pressure: The cold inflation
pressure is found on the Safety
Compliance Certification Label,
located in the driver's door jam.
*
Bead area of the tire: Area of
the tire next to the rim.
*
Sidewall of the tire: Area
between the bead area and the
tread.
*
Tread area of the tire: Area of
the perimeter of the tire that
contacts the road when mounted
on the vehicle.
*Rim: The metal support (wheel)
for a tire or a tire and tube
assembly upon which the tire
beads are seated.
Information Contained on the
Tire Sidewall
Both United States and Canada
Federal regulations require tire
manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and
describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire
Identification Number for safety
standard certification and in case
of a recall.

Information on P Type Tires
P215/65R15 95H is an example of
a tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
A.
P: Indicates a tire, designated
by the Tire and Rim Association,
that may be used for service on
cars, sport utility vehicles,
minivans and light trucks. Note:
If
your tire size does not begin with
a letter this may mean it is
designated by either the European
Tire and Rim Technical
Organization or the Japan Tire
Manufacturing Association. B.
215:
Indicates the nominal
width of the tire in millimeters
from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire.
C. 65:
Indicates the aspect ratio
which gives the tire's ratio of
height to width.
D. R:
Indicates a radial type tire.
E. 15:
Indicates the wheel or rim
diameter in inches. If you change
your wheel size, you have to
purchase new tires to match the
new wheel diameter.
F. 95:
Indicates the tire's load
index. It is an index that relates to
how much weight a tire can carry.
Note: You may not find this
information on all tires because it
is not required by federal law.
G. H:
Indicates the tire's speed
rating. The speed rating denotes
the speed at which a tire is
designed to be driven for extended
periods of time under a standard
condition of load and inflation
pressure. The tires on your vehicle
may operate at different
conditions for load and inflation
pressure. These speed ratings may
need to be adjusted for the
difference in conditions. The
ratings range from
81– 186 mph
(130– 299 km/h). These ratings
are listed in the following chart.
Note: You may not find this

(240 km/h), tire manufacturers
sometimes use the letters ZR. For
those with a maximum speed
capability over 186 mph (299
km/h), tire manufacturers always
use the letters ZR.
H. U.S. DOT Tire Identification
Number: This begins with the
letters DOT and indicates that the
tire meets all federal standards.
The next two numbers or letters
are the plant code designating
where it was manufactured, the
next two are the tire size code and
the last four numbers represent the week and year the tire was
built. For example, the numbers
317 mean the 31st week of 1997.
After 2000 the numbers go to four
digits. For example, 2501 means
the 25th week of 2001. The
numbers in between are
identification codes used for
traceability. This information is
used to contact customers if a tire
defect requires a recall.
I.
M+S or M/S:
Mud and Snow, or
AT:
All Terrain, or
AS:
All Season.
J. Tire Ply Composition and
Material Used:
Indicates the
number of plies or the number of
layers of rubber-coated fabric in
the tire tread and sidewall. Tire
manufacturers also must indicate
the ply materials in the tire and the
sidewall, which include steel,
nylon, polyester, and others.
K. Maximum Load: Indicates the
maximum load in kilograms and
pounds that can be carried by the
tire.
L. Treadwear, Traction and
Temperature Grades:
*Treadwear The treadwear grade
is a comparative rating based on
the wear rate of the tire when
tested under controlled conditions
on a specified government test
course. For example, a tire graded
150 would wear 1½ times as well
on the government course as a tire
graded 100.
238
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Wheels and Tires

*Traction: The traction grades,
from highest to lowest are AA, A,
B, and C. The grades represent the
tire's ability to stop on wet
pavement as measured under
controlled conditions on specified
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.
*
Temperature: The temperature
grades are A (the highest), B and
C, representing the tire's
resistance to the generation of
heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor
laboratory test wheel.
M. Maximum Inflation
Pressure:
Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label. The cold
inflation pressure should never be
set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have
additional markings, notes or
warnings such as standard load
or radial tubeless. Additional Information
