—After changing wheels
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designed in Part 8. If the pressure is low-
er, drive slowly to the nearest service sta-
tion and fill to the correct pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat
tire securely.
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified in Part 8 with a torque wrench
and have a technician repair the flat tire.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are securely
in place in their storage location to
reduce the possibility of personal in-
jury during a collision or sudden
braking.
(b) Using flat bed truck (a) Towing with wheel lift type truck—
—From rear —From front
If towing is necessary, we recommend
you to have it done by your authorized
Toyota CNG dealer or a commercial tow
truck service. In consultation with them,
have your vehicle towed using either (a)
or (b).
Only when you cannot receive a towing
service from your authorized Toyota
CNG dealer or a commercial tow truck
service, tow your vehicle carefully in
accordance with the instructions given
in “—Emergency towing” in this part.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following few
precautions are observed. If necessary,
show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
If your vehicle needs to be
towed—

High pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
attention to these areas as it is difficult
to see all the mud and dirt. It will do
more harm than good to simply wet the
mud and debris without removing them.
The lower edge of doors, rocker panels
and frame members have drain holes
which should not be allowed to clog
with dirt as trapped water in these
areas can cause corrosion.
Wash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Toyota” for
more tips.
Check the condition of your vehicle’s
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair.Check the interior of your vehicle. Wa-
ter and dirt can accumulate under the
floor mats and could cause corrosion. Oc-
casionally check under the mats to make
sure the area is dry. Be particularly care-
ful when transporting chemicals, cleans-
ers, fertilizers, salt,
e tc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full−size
shields, which come as near to the ground
as possible, are the best. We recommend
that the fittings and the area where the
shields are installed be treated to resist
corrosion. Your authorized Toyota CNG
dealer will be happy to assist in supplying
and installing the shields if they are rec-
ommended for your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage. If you wash your vehicle in
the garage, or if you drive it in covered
with water or snow, your garage may be
so damp it will cause corrosion. Even if
your garage is heated, a wet vehicle can
corrode if the ventilation is poor.Washing your Toyota
Keep your vehicle clean by regular
washing.
The following cases may cause weakness
to the paint or corrosion to the body and
parts. Wash your vehicle as soon as pos-
sible.
When driving in a coastal area
When driving on a road sprinkled with
antifreeze
When having stuck of coal tar, tree
sap, bird droppings and carcass of an
insect
When driving in the areas where there
is a lot of smoke, soot, dust, iron dust
and chemical substance
When the vehicle becomes remarkably
dirty with dust and mud
Hand−washing your Toyota
Work in the shade and wait until the
vehicle body is not hot to the touch.
CAUTION
When cleaning under floor or chassis,
be careful not to injure your hands.

Cleaning the interior
CAUTION
Do not wash the vehicle floor with
water, or allow water to get onto the
floor when cleaning the vehicle interi-
or or exterior. Water may get into
audio components or other electrical
components above or under the floor
carpet (or mat) and cause a malfunc-
tion; and it may cause body corro-
sion.
Vinyl interior
The vinyl upholstery may be easily
cleaned with a mild soap or detergent
and water.
First vacuum over the upholstery to re-
move loose dirt. Then, using a sponge or
soft cloth, apply the soap solution to the
vinyl. After allowing it to soak in for a few
minutes to loosen the dirt, remove the dirt
and wipe off the soap with a clean damp
cloth. If all the dirt do not come off, re-
peat the procedure. Commercial foaming−
type vinyl cleaners are also available
which work well. Follow the manufacturer ’s
instructions.
NOTICE
Do not use solvent, thinner, gasoline
or window cleaner on the interior.
Carpets
Use a good foam−type shampoo to
clean the carpets.
Begin by vacuuming thoroughly to remove
as much dirt as possible. Several types of
foam cleaners are available; some are in
aerosol can sand others are powders or
liquids which you mix with water to pro-
duce a foam. To shampoo the carpets,
use a sponge or brush to apply the foam.
Rub in overlapping circles.
Do not apply water—the best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
NOTICE
Do not use dye or bleach on the
belts—it may weaken them.
Do not use the belts until they be-
come dry.
Windows
The windows may be cleaned with any
household window cleaner.
NOTICE
When cleaning the inside of the win-
dows, be careful not to scratch or
damage the heater wires on the rear
window.
Air conditioning control panel, car au-
dio, instrument panel,
c onsole panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly
w ipe off dirt.

IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7−3 for additional in-
formation.
Engine coolant level
Make sure the coolant level is between
the “FULL” and “LOW” lines on the see−
through reservoir when the engine is cold.
See Chapter 7−2 for additional information.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el lines on the case. Add only distilled
water when replenishing. See Chapter 7−3
for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7−2 for additional information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7−2 for addi-
tional information.Power steering fluid level
Check the level through the reservoir. The
level should be in the “HOT” or “COLD”
range depending on the fluid temperature.
See Chapter 7−2 for additional information.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)Be on the alert for changes in perfor-
mance, sounds, and visual tip−offs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat−looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake; pedal almost touches
floor; vehicle pulls to one side when
braking
Engine coolant temperature continually
higher than normal
Does your vehicle need
repairing?

If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this part.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do−it−yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do−
it−yourself maintenance, see “Parts and
tools”.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:CAUTION
Never work on the fuel system by
yourself. Any work on this system
must be performed by your autho-
rized Toyota CNG dealer. If an un-
qualified person works on it incor-
rectly causing fuel leaks etc., a fire
hazard or explosion may occur,
which is very dangerous.
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartment—the engine, radiator,
exhaust manifold and spark plug
boots, etc.—will be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do−it−yourself service
precautions

169
CAUTION
Do not mix radial, bias belted, or
bias−ply tires on your vehicle. It
can cause dangerous handling char-
acteristics, resulting in loss of con-
trol.
Do not use tires or wheels other
than the manufacturer ’s recom-
mended size.
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See “If you have a flat tire” in Part 4 for
tire change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
Rotating tires
To equalize the wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
12000 km (7500 miles). However, the
most appropriate timing for tire rotation
may vary according to your driving hab-
its and road surface conditions.
See “If you have a flat tire” in Part 4 for
tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out−of−balance
wheels, or severe braking.
CAUTION
Do not include a compact spare tire
when rotating the tires. It is designed
for temporary use only.
