floor. Do not apply water from a
high-pressure washer nozzle
directly to the electric connectors.
Failure to observe this precaution
can lead to faulty operation of the
electrical system. If an automatic
car or truck-wash is used with
vehicles having dark or metallic
coating, the painted surfaces can be
damaged by the brushes, lose their
luster or be very noticeably
scratched.
Do not direct a large amount of
water at the air inlet openings. Do
not apply water to the engine
compartment or at electrical
components. Failure to observe this
precaution can lead to a poorly
starting and operating engine and
problems in the electrical system.
Ensure that mirrors and the antenna
are retracted before washing the
vehicle.
If an automatic car or truck-wash
must be used, avoid a
high-temperature, high pressure
type machine. Failure to observe
this precaution can lead to heat
deformation and breakage of plastic
components, or to water leaks intothe cab. When using an automatic
car or truck-wash, ensure that a
distance of at least 0.4 m
(15.75 inches) is maintained
between the nozzle and the vehicle,
and when washing door windows,
that the spray is perpendicular to
the surface of the glass.
Ensure that all detergent is fully
washed and wiped away.
Particularly in the case of strong
alkaline detergents (typically those
for industrial uses), there is a
danger that hairline cracks can
develop in lighting-cluster lenses if
the vehicle is operated without
detergent being fully wiped away.
Always read the detergent
manufacturer's instructions carefully
before use. Airborne dirt that
adheres to plastic front bumpers as
a result of rain, for example, can be
difficult to remove. In such a case,
use a commercially-available
cleaner to clean away the dirt, and
then apply a wax for use with plastic
components.Vehicle Storage
In order to maintain your vehicle's
attractive appearance as long as
possible, special consideration must
be given to its storage location.
If the vehicle is stored or kept for an
extended period of time in any of
the following locations, a chemical
change may occur in the paint work,
resulting in staining, discoloration,
rusting, and corrosion of
components.
.
Locations where a large amount
of oily matter, soot, heavy smoke
or metal powder can adhere to
the vehicle.
. Areas around pharmaceutical
plants and other facilities that
discharge chemical matter.
. Coastal areas
. Locations where a large amount
of dead bugs, bird droppings or
tree sap can adhere to the
vehicle.

Vehicle Care 337
Polishing and Waxing
Periodic polishing and waxing is
recommended to remove built-up
residue and eliminate any
"weathered" appearance.
Your authorized dealer offers
several polishes and cleaners which
have proven value in maintaining
original finish appearance and
durability.
Painted and chrome-plated surfaces
should be waxed once or twice a
month, or whenever water is being
poorly repelled on the surfaces.
Ensure that wax is not applied in
direct sunlight, and that the
temperature of the painted surface
is no more than 40 °C (104 °F).
Always follow the instructions
provided with your wax product.
Do not use wax containing abrasive
material. Failure to observe this
precaution can lead to scratching of
painted surfaces or plastic
components.
The application of wax to rubber
component surfaces can result in
permanent whitening.Wax must not be applied to the
windshield. Failure to observe this
precaution can result in irregular
reflection of light, impairing
your view.
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Washing with water is all that
is usually needed.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of wax,
rubbed to a high polish, is
recommended for all bright metal
parts.
Weatherstrip Lubrication
All weatherstrips should be
periodically lubricated (minimum of
every 6 months) with a silicone
grease lubricant. A thin film of
silicone grease lubricant should be
applied using a clean cloth. Silicone
grease application will lengthen
weatherstrip life, help sealing, and
assist in eliminating squeaks.
Windshield Care
Wax must not be applied to the
windshield. A layer of wax can
impair your view in rainy weather
and can also lead to rough
movements of the windshield wiper.
If engine oil or grease comes into
contact with the windshield, staining
or discoloration may result. It must
be immediately cleaned away.
If not fully cleaned by the windshield
wipers, the windshield should be
cleaned using glass cleaner. If your
windshield is not clear after using
the windshield washer, or if the
wiper blade chatters when running,
wax or other material may be on the
blade or windshield.
The windshield wipers on your truck
can be pulled out from the
windshield to provide easier access
for cleaning.
Clean the outside of the windshield
with a non-abrasive cleaner. Your
windshield is clean if beads do not

form when rinsing with water. Clean
the blade by wiping with a cloth
soaked in a solution of one-half
water and one-half methanol
alcohol. Then rinse the blade with
water.
The windshield wiper arms may be
swung out, away from the glass, to
provide easy access for cleaning.
Do not hang on to the roof marker
lights while cleaning the windshield
or damage may occur (resulting in
possible water leakage).
External Diesel Engine
Cleaning
The engine does not need periodic
cleaning, nor is it recommended.
If you insist on cleaning the engine,
clean it only when it is cold, never
when it is warm or hot, and never
when the engine is running.
Spraying or pouring water or other
fluids on your engine when it is
warm or hot, or when it is running,
can cause serious damage to the
engine and its components,
particularly the fuel supply pump.

Cooling efficiency is compromised
when there is dirt or dust plugging
air passages in the radiator core
and charge air cooler core (diesel).
This can also cause corrosion of
these cores. Wash the radiator core
with tap water every 24 months.
Make sure to turn the engine off and
remove the key from the engine
control switch before cleaning
cores.
The engine, exhaust pipe, and
radiator will be hot immediately after
the vehicle is driven. Be careful
around these parts to prevent burns.
Clean the engine when it is cold.
Do not clean the radiator, charge air
cooler (diesel) and their surrounding
areas using water that is supplied
under high pressure. Doing so may
cause damage.
When cleaning the radiator core (1)
and charge air cooler core (2) , do
not crush or damage the fins (3).
The fins are very fragile so be
careful not to bend them out of
shape. If they become deformed,
their cooling efficiency will be
impaired. Before cleaning, take
steps to ensure that no water will
splash onto the surrounding
electrical components and wires.
If stubborn dirt still remains even
after the radiator core and charge
air cooler core (diesel) have been
cleaned, have the vehicle inspected
and serviced.
Corrosion Protection
Your vehicle has been designed and
built to resist corrosion. Special
materials and protective finishes
were used on most parts of your
vehicle when it was built to help
maintain good appearance,
strength, and reliable operation.
However, some parts which
normally are not visible (such as
those under the vehicle and under
the hood) are such that surface rust
will not affect their reliability. So
corrosion protection is not needed
or used on these parts.
Sheet Metal Damage
If your vehicle is damaged and
requires sheet metal repair or
replacement, make sure the body
repair shop applies anti-corrosion
material to the parts repaired or
replaced so that corrosion protection
is restored. (Also see "Finish
Damage" which follows.)
Foreign Material Deposits
Calcium chloride and other salts,
ice-melting agents, road oil and tar,
tree sap, bird droppings, chemicals

necessary equipment, you should
let your authorized dealer's service
department or another qualified
service center do these jobs.
The schedule includes general
maintenance which you or a
qualified technician should perform
periodically.
Explanation of Vehicle
Maintenance and Log
The following is a brief explanation
of normal vehicle use.
NORMAL VEHICLE USE—The
maintenance instructions contained
in this section are based on the
assumption that your vehicle will be
used as designed:
.To carry passengers and cargo
with the limitations indicated on
the vehicle VIN and GVW plate.
. On reasonable road surfaces
within legal operating limits.
. On a daily basis, as a general
rule, for at least several miles/
kilometers. Unusual operating conditions, such
as driving in dusty areas (sweeper,
agricultural or off-road vehicles),
extended idling (refrigeration
vehicles), or vehicles operated for
frequent short trips, will require
more frequent vehicle maintenance.
The log groups items according to
mile/kilometer service intervals. Use
the item codes (letter and number)
to find the description of the
maintenance and the time intervals.
Follow whichever interval comes
first, time or miles/kilometers.
After the maintenance services are
performed, insert the month, day
and mileage/ kilometers in the area
provided next to the serviced item.
The services shown up to
176 000 km (110,000 miles) are to
be repeated after the initial
176 000 km (110,000 miles) at the
same intervals.
Severe Driving Conditions
A vehicle operated under severe
conditions (see list below) requires
more frequent maintenance. .
Frequent short trips of less than
6 kilometers (4 miles) in
moderate temperatures
. 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
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
