gas engines, to learn which
wheels and tires are correct, look
at the "Vehicle Certification and
Greenhouse Gas (GHG)
Emissions Plate" on the left side
rear pillar panel below the striker
(single cab) or on the left center
pillar panel beside the shoulder
seat belt anchor (crew cab).
Wheel size is also stamped on
the side of each wheel.
To help avoid personal injury and
property damage if a wheel must
be changed, seek expert tire
services if you can. If you must
remove the wheel without any
such help, do the following:. If the tire looks as if it may
be underinflated, stand to
the side and check whether
the wheel assembly
appears normal by
comparing it to another
wheel assembly on the
vehicle.
(Continued)
Warning (Continued)
.Let the air out of the tire by
taking out the valve core.
If you have a way to put air
back in a tire, note that it is
good safety practice to let
the air out of both tires of a
dual assembly before taking
off the damaged tire and rim
assembly from the vehicle.
After letting out the air, take
off the tire and rim assembly
and install a spare tire and
rim assembly.
If your vehicle is equipped
with a differential lock
system or limited slip
differential (LSD), it might
start moving when the
engine power is transmitted
to the rear axle even when
one of the wheels on the
axle is raised clear of the
ground. Do not start the
engine with any rear wheel
in contact with the ground.
(Continued)
Warning (Continued)
If you are not fully
experienced on the
procedures to follow, and/or
are not equipped with the
proper tools and equipment,
again, do not attempt to
raise the vehicle, or remove
or install the tire and wheel
assembly—seek expert tire
services.
. Do not put air back in a tire
that has been run flat, or is
seriously low on air, without
first having the tire taken off
the wheel and the tire
checked for damage.
. Note that taking off and
mounting tires on wheels
requires proper tools, safety
equipment and special
training. A person can be
severely injured or killed
and damage can result from
using the wrong service
methods. Truck tires and

from industrial chimneys and other
foreign matter may damage vehicle
finishes if left on painted surfaces.
Prompt washing may not completely
remove all of these deposits. Other
cleaners may be needed. When
using chemical cleaners, be sure
they are safe for use on painted
surfaces.
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be
repaired promptly. Bare metal will
corrode quickly and may develop
into major repair expense. Minor
chips and scratches can be repaired
with touch up materials available
from your authorized dealer or other
service outlets. Larger areas of
finish damage can be corrected in
your dealer's body and paint shop.
Underbody Maintenance
Corrosive materials used for ice and
snow removal, and dust control can
collect on the underbody. If these
materials are not removed,
accelerated corrosion (rust) can
occur on underbody parts such asfuel lines, frames, floor pan and
exhaust system even though they
have been provided with corrosion
protection.
At least every spring, flush these
materials from the underbody with
plain water. Take care to clean well
any areas where mud and other
debris can collect. Sediment packed
in closed areas of the frame should
be loosened before being flushed.
If desired, your authorized dealer
can do this for you.
Interior Care
General
Remove dust and dirt from the
interior of the cab using an
automotive cleaner or vacuum
cleaner, and gently wipe surfaces
clean using a cloth wet with warm or
cold water.
{Warning
Water should never be sprayed
directly into the interior of the cab
when cleaning. Failure to observe
this precaution can lead to vehicle
malfunction and possibly to fire if
water should enter the audio
system or other electrical
components located underneath
the floor carpet.
Petroleum ether, gasoline and
other organic solvents should not
be used to clean safety belts. In
addition, safety belt webbing
should be neither bleached nor
redyed. Failure to observe these
precautions can lead to the
performance or strength of the
safety belts being impaired. In the
case of a collision, therefore, the
safety belts could be insufficiently
effective, and serious
life-threatening injuries could
result. When cleaning, use warm
water in which a small amount of

Warning (Continued)
neutral detergent has been
dissolved to gently wipe the
safety belts.
Follow the manufacturer's advice
whenever cleaning agents or
other chemicals are used, inside
or outside the vehicle. Some
cleaners may be poisonous or
flammable, and improper use may
cause personal injury or damage.
When cleaning the inside or
outside of the vehicle, do not use
volatile cleaning solvents, such as
acetone, lacquer thinners, enamel
reducers, nail polish removers; or
such cleaning materials as
laundry soaps, bleaches or
reducing agents, except as noted
in the following fabric cleaning
advice on stain removal. Never
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.(Continued)
Warning (Continued)
Open all vehicle doors for
ventilation when ANY cleaning
agents or other chemicals are
used in the interior. Overexposure
to some vapors may result in a
health problem that is more likely
to occur in small, unventilated
spaces.
You and others could be seriously
injured.
The interior of the vehicle must
never be cleaned using acidic or
alkaline solvents, or petroleum
ether, gasoline, and other organic
solvents. Failure to observe this
precaution can result in
discoloration and staining. It should
be noted that certain types of
cleaning products contain these
compounds. Be sure to read
cleaning product labels carefully.
Air fresheners (liquid, solid, gel or
plate types) must not come into
direct contact with, or spill onto,
interior components such as the air conditioning or audio system.
Compounds contained in these
products can cause discoloration,
staining or peeling of paint.
Glass cleaners that contain these
compounds must not be used to
clean the inside of the windshield or
window glass. To clean the glass,
wipe it using a cloth wet with warm
or cold water.
To avoid possible permanent
discoloration of light colored seats,
Do not let materials with non-fast
colors come into contact with seat
trim materials until these materials
are totally dry. This includes certain
types of casual clothing, such as
colored denims, corduroys, leathers
and suedes; also decorative paper,
With the use of modern trim
materials, it is very important that
you use proper cleaning techniques
and cleaners. Failing to do this on
the first cleaning may result in water
spots, spot rings or setting of stains
or soilage - all of which are more
difficult to remove in a second
cleaning.
