. Keep cigarettes and other
flames away from the vehicle.
. Before opening the fuel tank
filler cap, touch a metallic object
to discharge static electricity
from your body.
. When filling, place the nozzle
deeply into the fuel tank. If you
try to fill more fuel by pulling out
the nozzle from the fuel tank, the
fuel may spill out, thus causing
danger.
. Be sure to wipe off the fuel that
is spilled at refueling.{Warning
Fuel vapor is highly flammable.
Be careful not to inhale fuel vapor
when refueling the vehicle.
If you have a static charge
buildup on your body while
refueling the vehicle, a spark
caused by its discharge could
ignite the fuel, resulting in burns.
All parts of the refueling
procedure (from opening the fuel
tank filler cap to completing the
refueling and closing the fuel tank
filler cap) must be performed by
the same person.
Other people may be carrying
static electricity. Do not allow
them to approach the fuel filler.
The person performing the
refueling procedure must not
return to the seat in the cab
part-way through the procedure.

{Warning
To help avoid personal injury, take
care when doing any
maintenance or making any
check or repair. Follow

vehicle or its equipment. If you
have any questions about
carrying out some service, have
the work done by a skilled
technician.
To prevent personal injury, keep
hands, tools and clothing clear of
the engine cooling fan when the
engine is running.
The engine, exhaust pipe and
radiator will be hot immediately
after the vehicle is driven. Be
careful around these parts to
prevent burns. Perform all checks
when the engine is cold.
Do not perform work near an
open flame or other heat sources.
Do not let the engine run in poorly
ventilated garages or sheds. This
could cause carbon monoxide
poisoning.(Continued)
Warning (Continued)
Performing maintenance work on
a truck or chassis can be
dangerous. In trying to do some
jobs, you can be seriously injured.
Do your own maintenance work
only if you have the required
know-how and the proper tools
and equipment for the job. If you
have any doubts, contact your
dealer.
You and others could be seriously
injured.
For gasoline vehicles, pull firmly on
the parking brake lever and put the
transmission in neutral. Move the
selector lever to “P”and make sure
the shift indicator displays "P".
For diesel vehicles, pull firmly on the
parking brake lever and move the
selector lever to "P" and make sure
the shift indicator displays "P".
Make sure to turn off the engine and
remove the key from the engine
control switch before performing any
checks. Select a place with a solid and level
surface to perform the checking and
maintenance work. Make sure to
chock the wheels. It would be very
dangerous if the vehicle started
to move.
For gasoline vehicles, when
performing work on the electrical
system, be sure to remove the cable
from the negative terminal on the
battery.
For diesel vehicles, when
performing work on the electrical
system, begin by turning the engine
control switch to the "LOCK"
position, wait at least 3 minutes, and
then disconnect the negative cable
from the negative terminal on
battery. If the negative cable is
disconnected within 3 minutes, the
engine control module may
malfunction.
For gasoline vehicles, when working
on the fuel line or fuel pump,
remove the fuel tank filler cap. The
fuel system is under pressure and
the fuel will overspill unless the
pressure is relieved, possibly
leading to combustion or a fire.

Vehicle Care 247
For diesel vehicles, when working
on the fuel line or fuel filter, remove
the fuel tank filler cap. The fuel
system is under pressure and the
fuel will overspill unless the
pressure is relieved, possibly
leading to combustion or a fire.
Do not make engine adjustments
yourself. Be sure to consult your
dealer.
Use only appropriate tools.
Oils, brake fluid and engine coolant
have lubrication, cooling and rust
prevention functions. If these liquids
deteriorate through loss or
contamination, it will cause a
decline in the performance of the
parts and such problems as seizure
or malfunctioning. Replenish or
change these liquids when
performing the checks (daily and
periodic checks) as required by the
relevant regulations or in
accordance with the Maintenance
Schedule (when either the specified
driving distance or period of time,
whichever comes first, has expired).Confirm that all systems and
components are normal after
performing the work.
Do not leave the removed parts or
tools in the engine compartment.
They could damage the equipment if
caught in the belts or other moving
components.
Dirty water, dirt and other impurities
seriously impair the effectiveness of
the oil, grease and fluids, and
damage the parts. Exercise all due
caution to prevent waste or other
refuse from coming in contact with
parts or materials that have been
removed when changing or
replenishing them.
Do not step on the engine or climb
onto it. You could cause an engine
failure by, for example, damaging
the cylinder head cover or various
connectors.
Electric Welding
Careless electric welding of vehicle
parts can cause welding current to
flow back through the vehicle’s
ground circuit and damage electrical
and electronic parts so that they donot function normally. Whenever
electric welding is necessary,
consult your dealer.
Cab Tilting
Before Tilting the Cab (Single Cab
Model)
{Warning
To help avoid personal injury and
property damage:
. Park the vehicle on level
ground and check that there
is enough space in front of
and above the cab.
. Set the parking brake firmly
and block the front wheels.
. Move the selector lever in
the "P" position.
. Secure loose articles in
the cab.
. Stop the engine.
