148IN CASE OF AN EMERGENCY
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve-
hicle, and turn on your emergency
flashers. Put the transmission in neu-
tral and apply the parking brake. Turn
off the air conditioning if it is being
used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the engine access hole cover
or tilting the cab. If there is no coolant
or steam boiling over, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid serious injury, keep the
engine access hole cover closed or
the cab lowered until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine im-
mediately. Call any authorized Toyota
dealer or repairer, or another duly qual-
ified and equipped professional, for as-
sistance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, you may
help the engine cool down more quickly
by running it at about 1500 rpm for a
few minutes with the accelerator pedal
lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type, see “Coolant type
selection” on page 191 in Section 7−2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.

CORROSION PREVENTION AND APPEARANCE CARE173
CAUTION
DDo not splash or spill liquid in the
vehicle. Doing so may cause electri-
cal components etc. to malfunction
or catch fire.
DWhen cleaning the interior (espe-
cially instrument panel), do not use
polish wax or polish cleaner. The
instrument panel may reflect off the
windshield, obstructing the driver ’s
view and leading to an accident,
resulting in death or serious injury.
NOTICE
zDo not wash the vehicle floor with
water, or allow water to get onto
the floor when cleaning the vehicle
interior or exterior. Water may get
into audio components or other
electrical components above or un-
der the floor carpet (or mat) and
cause a malfunction; and it may
cause body corrosion.
zWhen cleaning the interior, do not
use polish wax or polish cleaner.
The instrument panel’s or other in-
terior part’s painted surface may be
damaged.
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.
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
zDo not use dye or bleach on the
belts—it may weaken them.
zDo not use the belts until they be-
come dry.
Windows
The windows may be cleaned with any
household window cleaner.

DO−IT−YOURSELF MAINTENANCE: Introduction185
If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this Section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
This Section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
6, there are still a number of items that
must be done by a qualified technician
with special 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
DWhen 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.)
DRight after driving, the engine
compartment—the engine, radiator,
exhaust manifold and power steer-
ing fluid reservoir, etc.—will be hot.
So be careful not to touch them.
Oil and fluids may also be hot.
DIf the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
DDo not leave anything that may
burn easily, such as paper or rags,
in the engine compartment.
DDo not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
DBe extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
DDo not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
DBe sure that the engine switch is
off if you work near the electric
cooling fans. With the engine
switch on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
DUse eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
DUsed 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.
DDo not leave used oil within the
reach of children.
DDispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
DTake care when filling the brake and
clutch fluid reservoirs because
brake fluid can harm your hands or
eyes. If fluid gets on your hands or
in your eyes, flush the affected area
with clean water immediately. If you
still feel uncomfortable with your
hands or eyes, go to the doctor.

194DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
Treadwear indicator
CHECKING YOUR TIRES
Check the tire’s tread for treadwear in-
dicators. If the indicators show, replace
the tires. The location of treadwear in-
dicators is shown by the “TWI” or “”
marks, etc., molded on the sidewall of
each tire.
The tires on your Toyota have built−in
treadwear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.).
If you have tire damage such as cuts,
splits, cracks deep enough to expose
the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be prop-
erly repaired due to the size or location
of a cut or other damage, it should be
replaced. If you are not sure, consult with
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional.
If air loss occurs while driving, do not
continue driving. Driving even a short dis-
tance can damage a tire beyond repair.Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater load capacity as the
originally installed tires.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
DDo not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
DDo not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DDo not mix tires of different makes,
models or tread patterns, and do
not mix tires of remarkably different
treadwear. This may cause danger-
ous handling characteristics result-
ing in loss of control.
