Danger (Continued)
at least 5 minutes. Following this,
you should seek medical
assistance.
When using tools or other metal
objects in the vicinity of the
battery, take care to prevent them
from coming into contact with the
positive terminal. As the vehicle
itself will conduct electricity, any
such contact can result in a
short-circuit and a highly
dangerous electric shock.
A vehicle battery generates
extremely flammable hydrogen
gas. For this reason, operations
producing sparks or requiring the
usage of an open flame must
never be carried out near a
vehicle battery. Failure to observe
this precaution can result in
explosion if the hydrogen gas
ignites. Whenever wiping up
battery fluid, a damp cloth should
be used.(Continued)
Danger (Continued)
Batteries produce explosive
gases, contain corrosive acid,
and supply levels of electrical
current high enough to cause
burns. Therefore, to reduce the
risk of personal injury when
working near a battery:
. Always shield your eyes
and avoid leaning over a
battery whenever possible.
. Do not expose a battery to
open flames or sparks.
. Do not allow battery acid to
contact eyes or skin. Flush
any contacted area with
water immediately and
thoroughly, and get
medical help.
. Follow each step in the
jump starting instructions.
Always stop the engine whenever
the battery is to be inspected. (Continued)
Danger (Continued)
Dilute sulfuric acid is used as the
battery fluid. Special care must be
taken to ensure that this fluid
does not come into contact with
skin, clothing, or metal surfaces.
When disconnecting the cables
from the terminals, start with the
negative terminal. When
connecting them, the negative
terminal should be
reconnected last.
You and others could be seriously
injured.

{Warning
For safety and the protection of
the vehicle, do not push-start the
vehicle.
Never tow the vehicle to start
because a surge forward when
the engine starts could cause a
collision with the tow vehicle.
Also, this vehicle has a 12-volt
battery, 12-volt starting system
and a negative ground electrical
system; be sure the vehicle or
equipment used to jump start your
engine is also 12-volt. Use of any
other system may damage the
vehicle's electrical components.
Under no circumstances should
the battery's positive and negative
terminals be put in contact with
one another.
When connecting the cables,
under no circumstances should
the clips be allowed to touch each
other.(Continued)
Warning (Continued)
Do not disconnect a battery
terminal with the engine running.
It could cause a breakdown in the
electrical system.
You and others could be seriously
injured.
If you notice battery fluid leaking,
have an inspection carried out
immediately by the nearest dealer.
Diesel engine vehicles have more
than one battery because of the
higher torque required to start a
diesel engine. This procedure can
be used to start a single-battery
vehicle from any of the diesel
vehicle's batteries. However, at low
temperatures, it may not be possible
to start a diesel engine from a single
battery from another vehicle. 1. Use a vehicle that has a charged battery with the same
voltage. Make sure that the
other vehicle also has a 12-volt
starting system, and that it is the negative (–) terminal which
is grounded (attached to the
engine block, or frame rail).
2. Position the vehicle with the good (charged) battery so that
the booster (jumper) cables will
reach. But never let the
vehicles touch. Also, be sure
the booster cables to be used
do not have loose or missing
insulation.
3. In both vehicles, turn off the ignition (engine control) switch
and all lights and accessories
except the hazard flasher or
any lights needed for the work
area. In both vehicles, apply
the parking brake firmly and
move the selector lever to the
"P" position.

4. Unlatch the latches (1) andremove the battery cover (2)
and connect the jumper cables
in the numbered sequence in
the drawing below. Make sure
the cable clamps do not touch
any other metal parts.
Make sure the cables are not
on or near pulleys, fans or
other parts that will move when
the engine is started.
When it is difficult to start the
engine in a cold area, first start
the engine of the vehicle with
the booster battery or batteries
and a few minutes after that
start the engine of the disabled
vehicle.
5. After connecting the cables,start the engine of the vehicle
with the booster battery. 6. Slightly rev up the engine of
the vehicle with the booster
battery and start the engine of
the disabled vehicle.

3. No vehicle should ever be
towed over 88 km/h (55 mph).
4. Loose or protruding parts of damaged vehicles should be
secured prior to moving.
5. A safety chain system completely independent of the
primary lifting and towing
attachment must be used.
6. Operators should refrain from going under a vehicle which is
being lifted by the towing
equipment unless the vehicle is
adequately supported by safety
stands.
7. No towing operation which for any reason jeopardizes the
safety of the wrecker operator
or any bystanders or other
motorists should be attempted.Appearance Care
Exterior Care
Exterior Finish
The paint finish on your vehicle
provides beauty, depth of color,
gloss retention and durability.
While cleaning the vehicle, do not
grip the roofmarker lights to prevent
damage or water leakage.
Washing
The best way to preserve your
vehicle's finish is to keep it clean by
washing it often.
Wash the vehicle in lukewarm or
cold water. Do not use hot water or
wash your vehicle in the direct rays
of the sun. Do not use strong soap
or chemical detergents. All cleaning
agents should be flushed promptly
from the surface and not allowed to
dry on the finish.
These vehicles are designed to
operate under normal environmental
conditions to withstand natural
elements. However, unusual

294 Vehicle Care
conditions such as high-pressure
car washers may cause water to
enter inside the vehicle. If the
vehicle is operated with foreign
material adhering to the exterior,
this material may react chemically
with paint, resulting in staining,
discoloration, rusting or corrosion of
components. Also, the material may
become trapped within mechanical
components, adversely affecting
their functions or forming an
aerodynamic resistance. In the
following cases, therefore, the
vehicle must be washed and all
foreign matter removed.
.When soot, iron powder, dead
bugs, bird droppings, tree sap or
oily matter from coal tar and
smoke has adhered to painted
surfaces.
. When the vehicle has been
driven in coastal areas.
. When the vehicle has been
driven on roads where road
chemicals have been applied.
. When a large amount of mud or
dirt has adhered to the exterior. To wash the vehicle:
1. Fully turn on the tap, and wash out the undercarriage and
suspension.
2. Close all openings and wash the cab and cargo body panels
using a neutral detergent.
3. Clean wheels and tires using a brush and detergent.
4. After washing away all remaining detergent, use a
shammy or other clean cloth to
fully remove all moisture and
water droplets.
{Warning
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
(Continued)
Warning (Continued)
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. 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.
Do not apply water directly in order
to clean the cab interior. Failure to
observe this precaution can result in
malfunction or breakdown of
electronic control units and electrical
components, or in rusting of the cab

Vehicle Care 295
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
