or bodies of water. Instead, recycle
it by taking it to a used oil collection
facility which may be found in your
community.
Automatic Transmission
Fluid
{Warning
Overfilling of the automatic
transmission can cause the fluid
to be "PURGED" out of the
breather hose onto the hot engine
parts and can cause a fire.
You and others could be seriously
injured.
Both quality and quantity of fluid are
important factors that have a
significant influence on the
performance and durability of the
automatic transmission. Be sure to
use only the dealer recommended
fluid for replenishment, and observe
the specified fluid level. Too much or too little transmission
oil could damage your transmission.
Too much could cause your
transmission to overheat and fluid to
spill out from the breather hose. Be
sure to get an accurate reading if
you check your transmission fluid.
When cleaning around the dipstick
and guide tube, make sure that you
thoroughly wipe away all of the dirt
and dust etc. Failure to do so may
cause a fault in the transmission.
Do not let coolants (ethylene glycol
type), water based substances,
or other fluids etc., mix with the
fluid. Otherwise, degraded
performance and faulty operation of
the system will result.
Checking the Automatic
Transmission Oil level
This operation could be difficult and
you may choose to have this done
at your dealer.
If you choose to do it yourself, then
be sure to follow all the instructions
below or you could get a false
reading on the dipstick.Position of the Dipstick
For the single cab vehicle, the
dipstick is located to the left side of
the automatic transmission at the
rear of the engine. Tilt the cab up to
inspect it.

Warning (Continued)
eyes are still irritated or otherwise
feel abnormal, seek immediate
medical attention.
If the engine coolant gets on your
skin, rinse it off using a soap with
a large amount of water. Also,
if abnormality is seen, seek
medical attention.
Engine coolant is flammable, and
therefore, it must be kept away
from flames and other heat
sources. Engine coolant also
could ignite if it comes in contact
with a hot surface, such as the
exhaust manifold. Exercise
caution to prevent this from
happening.
You and others could be seriously
injured.
Preparing Engine Coolant
To prevent engine damage due to
freezing of the engine coolant and
to protect the cooling system from corrosion, use a mixture of the
recommended type antifreeze and
water. If the engine of the vehicle is
at
−30 °C (−22 °F) or above, the
coolant concentration should be
50%. Direct use of “50/50
Pre-diluted” product which is already
diluted to 50% concentration is
recommended. If the outside
temperature engine or vehicle is
used at −30 °C (−22 °F) or below,
coolant concentration of 55% is
recommended.
It is the owner ’s responsibility to:
. Maintain the engine cooling
system freeze protection at or
above −30 °C (−22 °F) (at or
below −30 °C (−22 °F) in colder
climates to ensure protection
against corrosion and loss of
engine coolant from boiling.
A 50/50 (55/45 for colder
climates) mixture of the
recommended type antifreeze
and water will provide freeze
protection to at or above −30 °C
(−22 °F), (at or below −30 °C
(−22 °F) in colder climates) and
boil protection to 128 °C (262 °F). Periodic replacement
of engine coolant is needed to
replenish the anticorrosion
additives that wear out with use.
Engine coolant that has become
dark in color shows that it needs
to be changed.
. Use only the recommended
coolant. See Recommended
Fluids and Lubricants 0349.
. Do not use methanol-base
antifreeze, alcohol or plain water
alone in your vehicle at any time.
They will boil at a lower point
than that at which the engine
coolant temperature gauge will
warn of overheating, and they do
not provide proper protection
against corrosion.
Engine Coolant Quantity
For the quantity of engine coolant,
see Capacities and Specifications
0 357. After changing the engine
coolant, check that the engine
coolant is up to the specified level.

Danger (Continued)
.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
wheels should be serviced
only by trained people using
the proper equipment.
. Never add air to your tires
unless an accurate pressure
gauge is also used. When
putting air in a tire on the
vehicle, stand to the side
and use a clip-on chuck and
hose extension. In choosing
the right tire pressure, be
careful not to exceed the
maximum pressure
capability shown on the tire;
see the tire pressure charts
in this manual.
(Continued)
Danger (Continued)
.Tire mounting or repair can
result in serious personal
injury or death, if not
performed correctly. This
section has detailed
instructions for proper wheel
and tire replacement, so be
sure to read and follow
them. Truck fleet owners
and operators: You can get
written instructions on truck
tire demounting, repair and
mounting from Rubber
Manufacturers Association
(RMA), 1400 K Street N.W.,
Washington, D.C. 20005,
and also from many tire
stores. Wheel Nut Torque{Warning
Never use oil or grease on studs
or nuts. Use the torque specified
for the type of wheels on the
vehicle. Snug all wheel nuts and
then tighten to the specified
torque in the numerical sequence
shown. Improperly tightened
wheel nuts could eventually allow
the wheel to come off while the
vehicle is moving, possibly
causing loss of control and
personal injury and property
damage.
When the vehicle, wheel or
fasteners are new, have a
technician tighten wheel stud nuts
and rim clamp nuts with a torque
wrench at 1 040 km (650 mi). This is
necessary because the clamping
system used on the wheels must
seat before the fastener will hold a
uniform clamp load and remain fully
tightened. Also have a technician

324 Vehicle Care
Warning (Continued)
use carbon tetrachloride,
gasoline, benzene or naphtha for
any cleaning purpose.
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, as well as 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 waterspots, spot rings, or setting of stains
or soilage
—all of which are more
difficult to remove in a second
cleaning.
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots,
or stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
. Remove stains as quickly as
possible before they set.
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.

.Follow specific instructions on
cleaner labels.
General Cleaning of Soiled or
Water Spotted Fabric Type
Trim with Foam Type Cleaner
Vacuum the area thoroughly to
remove any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim
along stitch or welt lines.
Use suds on a clean sponge. Do
not brush wet suede. Do not
saturate the material or rub it
harshly. Immediately after cleaning,
remove suds with a sponge and
rinse with a clean wet sponge. Wipe
off remaining residue with a slightly
damp absorbent towel or cloth.
Immediately after wiping, force-dry
the fabric with an air hose. A heat
dryer or heat lamp may be used.
Use caution with a heat dryer or
lamp to help prevent damage.
When trim materials with a sheen or
luster finish are dry, wipe the fabric
lightly with a soft, dry, clean cloth to
restore its sheen or luster. For suede, raise nap with a dry scrub
brush and vacuum to remove any
final traces of residue.
Spot Cleaning Fabric Type
Trim with Solvent Type Cleaner
Before trying to remove a spot or
stain from fabric, try to find out the
type and age of the spot or stain.
Some spots or stains can be
removed with water or a mild soap
solution. Spots or stains should
always be removed as soon as
possible.
Some types of stains or soilage,
such as lipstick, inks, and grease,
are very difficult (sometimes
impossible) to remove completely.
When cleaning this type of stain or
soilage, be sure not to enlarge the
soiled area.
.
Gently scrape excess stain from
the trim material with a clean,
dull knife or scraper. Use very
little cleaner, light pressure, and
clean cloths, preferably
cheesecloth. Cleaning should
start at the outside of the stain feathering towards the center.
Keep changing to a clean
section of cloth.
. When you clean a stain from
fabric, immediately dry the area
with an air hose, heat dryer,
or heat lamp to help prevent a
cleaning ring. Use caution with
heat dryer or lamp to help
prevent fabric damage.
. If a ring forms, immediately
repeat the cleaning operation
over a slightly larger area with
emphasis on feathering towards
its center. If a ring still remains,
mask off surrounding trim
sections and clean the entire
soiled area with a foam type
cleaner.

Service and Maintenance 329
.Frequent short trips of less than
16 kilometers (10 miles) in sub-
freezing temperatures
. Frequent and extended low-
speed engine operation (door-
to- door deliveries, stop- and- go
traffic, etc.)
. Driving on unpaved roads with
heavy dust
. Towing a trailer
Power Take Off (PTO) and
Extended Idle Use
When the vehicle is used with the
PTO equipment or used in a way
that requires extended idle time,
one hour of use shall be deemed
the same as 33 miles. See Driver
Information Center (DIC) 082 for
hourmeter.
Preventive Maintenance
As any mechanical device operates,
a certain amount of wear occurs.
The amount of wear depends on
certain variables –type and method
of operation and the schedule of
maintenance. These variables may be emphasized as critical to
malfunction but each is dependent
upon the other. For example, if a
vehicle is repeatedly overloaded,
driven at excessive speed or
improperly shifted, no schedule of
maintenance can prevent
malfunction. Also, if a preventive
maintenance schedule is not
followed, or is improperly carried
out, no amount of correct vehicle
operation will prevent malfunction.
If vehicle application, operation and
preventive maintenance schedules
and procedures are followed and
properly carried out, the life of the
vehicle will be greatly extended.
For example, regular attention to the
engine oil is essential. The oil level
must be periodically checked and oil
added whenever needed. Also, the
oil should be changed at the
intervals specified with the proper
quality and viscosity of oil. If your
engine should run excessively low
on oil or if the oil has lost its
lubricating qualities because of old
age, serious engine damage could
occur.
