Warning (Continued)
If a warning light comes on or a
buzzer sounds while you are
driving, immediately stop the
vehicle in a safe place and
perform checks.
Slow down sufficiently when
approaching a curve. Applying the
brakes or sharply turning the
steering wheel while turning the
curve could cause the cargo to
shift, the tires to slip and the
vehicle to tip onto its side.
Avoid scraping the tire sidewalls
against curbstones or driving over
dips and protrusions in the road
surface. You could damage the
tires, resulting in a blowout or
flat tire.
You and others could be seriously
injured.
Pulling Away After Stopping
and Parking
Before pulling away, check that
there are no children or obstructions
around the vehicle and confirm that
it is safe to pull away.
If you cannot see the area behind
your vehicle well enough to confirm
it is safe to back up, get out of the
vehicle and check behind it.
Make it a habit to look around and
confirm that it is safe to pull away
after a temporary stop (at traffic
lights, for example).
If the Windshield Fogs Up
Use the heater to blow hot air on the
windshield or dehumidify the cabin
using the air conditioner and place
the outlet selector knob in the
5or
4position.
Place the air selector lever in the
outside air position.
Nighttime Visibility
If there is an old film on the
windshield, the lights of oncoming
traffic will be reflected in many directions, making it hard for you to
see ahead. Use glass cleaner to
clean the glass and the wiper
blades.
Worn wiper blades cannot wipe the
windshield clean and thus cannot
maintain visibility. When the wiper
blades become worn, replace them
with new ones.
Do Not Attach Accessories to
the Windshield or Windows
{Warning
Do not attach ornaments, films or
other accessories to the
windshield or windows. They
would impair visibility. Also, any
plastic suction cups used to
attach accessories could cause a
fire or other accident by acting as
lenses.
You and others could be seriously
injured.

When Ice Prevents You from
Putting Your Key in the Door
or Opening the Door
If you try to force the key into the
door, you could bend it. And if you
try to pull the door open with undue
force, the rubber seal around the
door could come unstuck or become
damaged. Use warm water to melt
the ice, then quickly wipe it away
and open the door.
If the wipers, electric door mirrors,
or power windows freeze up, also
use warm water to melt the ice and
then operate the system. Otherwise,
you could damage the mechanism
and drain the battery. After that,
wipe the water away.
Before Driving in Cold Regions
Getting In and Out of the Vehicle
The step can get icy in cold regions.
Be careful not to slip when getting in
and out of the vehicle. Before Sitting in the Driver
’s Seat
Remove snow and ice from your
shoes when getting into the vehicle.
If you try to drive with snow on your
shoes, your shoes would slip on the
pedals and you would not be able to
press the pedals properly, meaning
that your driving would be
inconsistent. Also, the cabin could
become more humid, causing the
glass to fog up.
Check Fuel Level
Fuel consumption increases when
tire chains are used. Determine how
much fuel you need to reach your
destination and fill up the tank in
advance. Refer to Fuel for Diesel
Engines 0206.
Removing Snow from Glass
and Underbody
Do not use a sharp implement to
remove snow. Sharp edges could
damage rubber parts.
To maintain an adequate field of
view, use a plastic scraper to
remove snow and frost from the
glass surfaces. By using a plastic
scraper, you can remove the snow and frost without scratching the
glass. At this time, check whether
the wiper blades are frozen onto the
glass.
Also, look under the vehicle and
remove any lumps of ice that are
stuck to the underbody. Be careful
not to damage components.
Driving on Snowy or Frozen
Roads
On slippery roads, never accelerate
rapidly, brake hard, decelerate
rapidly or make sharp turns of the
steering wheel.
There is a risk of reduced grip
between the tires and road surface
and of increased braking distances.
The danger of icy road surfaces is
particularly great on bridges, in
shady places and where there are
puddles.
Keep your speed down and be sure
to use tire chains or winter tires on
snowy or frozen road surfaces.
Use engine brakes together with the
foot brakes to decelerate. Using the
exhaust brake on a slippery road
surface could cause the tires to slip.

Engine Exhaust
Engine Exhaust Emissions
Caution (Carbon Monoxide)
{Warning
Do not breathe exhaust gas
because it contains carbon
monoxide, which by itself has no
color or odor. Carbon monoxide is
a dangerous gas. It can cause
unconsciousness and can be
lethal.
Do not keep the engine running
for any length of time in a place
that is poorly ventilated. It is
particularly dangerous to run the
engine in a garage or other indoor
place that could easily fill with
exhaust gases because you could
suffer carbon monoxide
poisoning.
Inspect the exhaust pipe from
time to time. If you notice any
defect (for example, a damaged
joint, or a hole or crack caused by(Continued)
Warning (Continued)
corrosion), have checks and
maintenance performed by the
nearest dealer. Continuing to use
the vehicle without having the
defect repaired would be
dangerous because exhaust
gases could get into the cab and
cause carbon monoxide
poisoning.
If at any time you think exhaust
fumes are entering the cab, have
the cause determined and
corrected as soon as possible.
If you must drive under these
conditions, drive only with all
windows fully open. Prevent
carbon monoxide from entering
the cab. The best way is to keep
the engine exhaust system, cab
and cab ventilation system
properly maintained.
We recommend that the exhaust
system and cab be inspected by
a competent technician:(Continued)
Warning (Continued)
.Each time the vehicle has
an oil change.
. Whenever a change is
noticed in the sound of the
exhaust system.
. Whenever the exhaust
system, underbody or cab is
damaged or becomes
corroded.
To allow proper operation of your
vehicle's ventilation system, keep
the air inlet grille clear of snow,
leaves or other obstructions at all
times. Do not park with the
engine running or idle this vehicle
for more than 10 minutes with the
ventilation system control switch
in the OFF position. Even with the
ventilation system on, running the
engine while parked or stopped
for longer periods of time is not
recommended. Entry of carbon
monoxide into the cab is possible
with a poorly repaired, damaged, (Continued)

4. Fully retighten the air bleedplug (2) and wipe off any fuel
that may have adhered to the
plug or surrounding area.
5. Continue to operate the pump for 50 times.
6. Start the engine.
7. If the engine does not start, repeat steps 5 and 6 as
necessary until it does start.
After Starting the Engine 1. Without pressing the accelerator pedal, start the
engine.
2. After the engine has started, allow it to idle for about
5 seconds.
3. Fully press the accelerator pedal and increase the engine
speed to the maximum speed
for 10 seconds. (Repeat this
operation several times.)
Insufficient air bleeding can result in
faulty engine operation. Be sure,
therefore, to always carry out the
previous steps under "After starting
the engine".Filling the Tank
Be sure to obey the following
instructions when refueling the
vehicle:
. Stop the engine and close the
vehicle's doors and windows.
. 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.

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

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 techniquesand 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.
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
become "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.
Important —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.
