Three-way catalytic converter
The three-way catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION

Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases
flowing into the three-way catalyticconverter may cause it to overheat and create a fire hazard. To prevent
this and other damage, observe thefollowing precautions:
Use only unleaded gasoline.
Do not drive with an extremely lowfuel level; running out of fuel could
cause the engine to misfire, creat-ing an excessive load on the three- way catalytic converter.
Do not allow the engine to run atidle speed for more than 20 minu-
tes.
Avoid racing the engine.
Do not push-start or pull-start yourvehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good runningorder. Malfunctions in the engineelectrical system, electronic ignitionsystem/distributor ignition system
or fuel systems could cause an ex-tremely high three-way catalyticconverter temperature.
If the engine becomes difficult to start or stalls frequently, take yourvehicle in for a check-up as soon
as possible. Remember, your Toyotadealer knows your vehicle and itsthree-way catalytic converter system
best.
To ensure that the three-way cata- lytic converter and the entire emis-sion control system operate proper-ly, your vehicle must receive the
periodic inspections required by theToyota Maintenance Schedule. Forscheduled maintenance information,
refer to the separate ºOwner'sManual Supplement/MaintenanceScheduleº.

equire a longer
stopping distance in the following cases:
Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock brake system from operating at
full effectiveness.

If towing is necessary, we recommend
you have it done by your Toyota dealer
or a commercial tow truck service. In
consultation with them, have your ve-
hicle towed using either (a) or (b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in ºÐEmergency tow-
ingº 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.
Two-wheel drive modelsÐ
(a) Towing with wheel lift type truck
From frontÐ
Manual transmission:
We recommend using a towing dolly under
the rear wheels. If you do not use a tow-
ing dolly, release the parking brake and
put the transmission in neutral. Automatic transmission:

NOTICE
Never tow a vehicle with an automatic transmission from the front with therear wheels on the ground, as this
may cause serious damage to the
transmission.
From rearÐ Place the ignition key in the
ºACCº position.
NOTICE
When lifting wheels, take care to
ensure adequate ground clearancefor towing at the opposite end ofthe raised vehicle. Otherwise, the
bumper and/or underbody of thetowed vehicle will be damaged dur-ing towing.
Do not tow with the key removed or in the ºLOCKº position, as thesteering lock mechanism is not
strong enough to hold the frontwheels straight while towing.

CAUTION
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
compartmentÐthe engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill 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.
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 not leave used oil within the
reach of children.
Dispose 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.NOTICE
Remember that battery and ignition
cables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.
Add only demineralized or distilled water to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.
Do not allow dirt or anything elseto fall through the spark plug holes.
Do not pry the outer electrode of a
spark plug against the center elec-trode.
Use only spark plugs of the speci-fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic transmis-sion fluid, or the transmissioncould be damaged.
Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See ºFuse locationsº in Chapter 7- 1 for
locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
Part 8 of this manual for the functions
controlled by each circuit. Type A fuses can be pulled out by the
pull- out tool. The location of the pull-out
tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the ºCIGº,
ºRADIOº, ºDOMEº or ºA.Cº fuse, which
may be dispensable for normal driving,
and use it if its amperage rating is the
same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
as possible to the rating. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies.
If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Toyota dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
