If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components.
AIR SUSPENSION (IF EQUIPPED)
Note:Do not operate your vehicle without air in the suspension springs.
Operating your vehicle without air in the suspension springs damages the
suspension, degrades ride performance and may cause property damage.
The air suspension system automatically adjusts to different loads to
maintain a constant frame height, allows for ease of vehicle loading,
provides improved vehicle ride, and increased driver comfort.
Air Suspension Dump Switch
Note:The suspension dumps air when the ignition is in the accessory or
on position, but fills only when the ignition is in the on position.
A switch located in the overhead
switch pack controls the system. It
operates only when the ignition is in
the accessory or on position and the
air tanks have sufficient pressure to
fill the air springs. When you turn
off the ignition, the suspension
remains in whatever state it was last
set.
Pressing the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so your vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when using the
switch to release air pressure in the rear air shocks. Never
drive your vehicle when the warning lamp is illuminated and
there is low (or no) air pressure in the shocks.

BREAKING-IN
You need to break in new tires for approximately 300 miles
(480 kilometers). During this time, your vehicle may exhibit some unique
driving characteristics. Avoid driving too fast during the first 1000 miles
(1600 kilometers). Vary your speed frequently and change up through
the gears early. Do not labor the engine.
ECONOMICAL DRIVING
Several things affect your vehicle’s fuel economy, such as how you drive,
the conditions you drive under and how you maintain your vehicle.
You may improve your vehicle’s 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.
You may want to avoid doing these things since they may reduce your
vehicle’s fuel economy:
•Sudden 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 pounds (180 kilograms) of weight carried).
•Add particular accessories to your vehicle (such as bug deflectors,
roll bars and light bars, running boards, ski racks).
•Drive with the wheels out of alignment.

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).

Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure to cover all linkages, cables, levers and pins under your
vehicle with grease to prevent rust.
•Move vehicles at least 25 feet (8 meters) every 15 days to lubricate
working parts and prevent corrosion.
Removing Your 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 (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 feet (4.5 meters)
back and forth to remove rust build-up.
•Check fluid levels (including engine coolant, engine oil and fuel) to
make sure there are no leaks and fluids are at recommended levels.
•If you remove the battery, clean the battery cable ends and inspect.
Contact an authorized dealer if you have any concerns or issues.

TIRES
Tire Inflation Information
WARNING:Always maintain your tires in good condition.
Frequently check and maintain correct inflation pressures as
specified by tire manufacturers. Inspect periodically for abnormal wear
patterns and repair/replace cut or broken tire casings. Always use
experienced, trained personnel with proper equipment and correct
procedures to mount or remove tires and wheels. Failure to adhere to
these warnings could result in wheel or tire malfunction, damage to
your vehicle, personal injury, or death.
WARNING:To avoid personal injury or death, always follow
these instructions when mounting radial tires on wheels:
•Only personnel that have had proper training and experience should
mount or remove tires from rims or wheels.
•Use only heavy-duty rims or approved rims for radial tires. It may be
necessary to contact your wheel and rim distributor to determine if
you can use radial tires with your rims.
•If you are using a tube, make sure to use special radial tire tubes
because of the increased flexing of the sidewalls on radial tires.
•Never use anti-freeze, silicones, or petroleum-based lubricants when
mounting radial tires. Make sure to use only an approved lubricant as
an aid for mounting tires.
•Always inflate tires in a safety cage.
•Do not attempt to mix stud piloted wheels or fasteners with hub
piloted wheels or fasteners. To do so may cause premature wheel
failure resulting in property damage, personal injury, or death.
•Do not mix foreign (not made in North America) wheel-mounting
parts with domestic (made in North America) parts. Many foreign
wheel components look similar to, but are not the same as domestic
made components. Mixing components could cause wheel or fastener
failures and result in property damage, personal injury, or death.

WARNING(Continued)
•Do not change from aluminum wheels to steel wheels or vice-versa
without changing the mounting hardware where required or, in some
cases with flange nut mounting systems, changing the hub and stud
assembly. Mixing components could cause wheel or fastener failures
and result in property damage, personal injury, or death.
WARNING:An inflated tire and rim can be very dangerous if
improperly used, serviced or maintained. To avoid serious injury,
never attempt to re-inflate a tire which has been run flat or seriously
under-inflated without first removing the tire from the wheel assembly
for inspection. Do not attempt to add air to tires or replace tires or
wheels without first taking precautions to protect persons and property.
All tires with Steel Carcass Plies (if equipped):This type of tire
utilizes steel cords in the sidewalls. As such, they cannot be treated like
normal light truck tires. Tire service, including adjusting the air pressure,
must be performed by personnel trained, supervised and equipped
according to Federal Occupational Safety and Health Administration
(OSHA) regulations. For example, during any procedure involving tire
inflation, the technician or individual must utilize a remote inflation
device, and make sure that all persons are clear of the trajectory area.

Stay out of the trajectory (1) as indicated in the illustration.
WARNING:Do not mount tube type tires on tubeless wheels or
tubeless tires on tube type wheels. To do so could result in tire
or wheel failure and cause property damage, personal injury or death.
Preserving proper inflation pressure is a very important maintenance
practice to make sure safe vehicle operation and long life for the tires.
Failure to maintain correct inflation pressure may result in sudden tire
destruction, improper vehicle handling, and may cause rapid and
irregular tire wear. Therefore, inflation pressures should be checked daily
and always before long distance trips.
Follow the tire manufacturer’s recommended cold inflation pressure for
the tire size, type, load range (ply rating) and axle loading typical for
your operation. (Each steer axle tire load equals one-half steer axle
loading; each drive tire load is one-quarter the axle-loading if fitted with
four tires).

Checking Tire Pressure
Always check inflation pressure when tires are cold. Never bleed air from
hot tires to relieve normal pressure build-up. Normal increase in pressure
due to service conditions is 10–15 psi (69–103 kPa), which is allowable
in truck tires.
Tires should be properly inflated to manufacturers’ recommended
pressure for the size and service load in which the vehicle is being used.
See the specific tire manufacturer with which your vehicle is equipped
with for the latest information concerning service load and inflation
pressure.
It is particularly important to keep moisture from the inside of tires, and
proper selection of air compressor equipment, proper air line routing,
and the use of shop air dryers is strongly recommended to avoid
moisture in the high pressure air used for tire inflation.
Under-inflation
Do not allow tires to become under-inflated; increased flexing due to
under-inflation causes heat build-up within the tire components. This
leads to reduced strength, breakdown of the rubber compounds, and
possible separation of the tire components (such as ply and tread
separation and reduced retreadability).
Under-inflation is the primary cause of premature tire concerns including
sudden loss of air. In addition, low inflation causes an increase in rolling
resistance. This results in reduced fuel mileage, a loss in tread mileage,
and uneven wear due to increased tread movement. To determine proper
inflation, see the tire manufacturer load and inflation guide, which you
can find on the tire manufacturer website or at your local truck tire
dealer.
Tire Inspection
Check the tires for abnormal wear patterns and proper inflation
pressures. Repair or replace cut or broken tire casings.
Inspect tires for the following conditions. If any are present, remove and
repair, retread, or scrap the tire as the condition dictates.
•Any blister, bump or raised portion anywhere on the surface of the
tire tread or sidewall (other than a bump made by a repair). These
indicate the start of internal separation.
•Any cut that reaches to the belt or ply cords, or any cut that is large
enough to grow in size and depth.
•Any nail or puncturing object.
•If a tread groove is holding a stone or object that is starting to drill
into the tread base, remove the object.

Proper tire inflation, toe-in adjustment, loads, and road speeds are
important factors governing tire mileage, steering ease and
maneuverability.
Tire Loading
WARNING:Loading tires beyond their rated capacity decreases
tire life requiring more frequent replacement of tires. Overloading
creates an unsafe condition that may result in sudden air loss from a
tire failure resulting in an accident that could cause property damage,
personal injury or death.
Note:Your GAW/GVW rating is correct at the time of your vehicle
production, and reflects the exact rating of the tires specified. When
replacing tires, make sure that the replacement tire load rating (listed in
pounds and kilograms on the tire sidewall) is the same or higher than
the tire that you are replacing. Failure to do so adversely affects
maximum load carrying capacity. Tires with the same size specification
do not always have the same load specification.
Note:The tire installed as original equipment may not be the same as
the tire specified on the DOT label, but has enough load capacity to
carry the GAW/GVW specified.
Note:Tires with the same size specification do not always have the same
load specification.
Matching Tires
Dual Tires:Dual tires should be matched using tires of equivalent size.
Do not mount tires that differ more than one-quarter inch (6
millimeters) in diameter or three-quarters inch (19 millimeters) in
circumference on the same dual wheel assembly.
Mixing:Never mix bias and radial tires on this vehicle. Never mix
different tire sizes or constructions on the same axle.
Rotation:
Rotation is always advisable:
•If there is irregular wear on the front (steering) axle tires, move to
rear position.
•In a dual assembly, reverse the position of the tires if one tire wears
much faster than its mate does.
•On the drive axle, if heel and toe wear or alternate lug wear occurs,
rotating the tires from one end of the axle to the other end of the
axle may help even out this wear.
