The Three- way catalytic converter is an
emission control device installed in the
exhaust system.
Its 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 overheatand create a fire hazard. To prevent
this and other damage, observe thefollowing precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel couldcause 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 min-
utes.
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 ignition
system/distributor ignition systemor fuel system could cause an ex-
tremely high three- way catalytic
converter temperature.
If the engine becomes difficult tostart or stalls frequently, take your
vehicle in for a check- up as soonas possible. Remember, your Toyota dealer knows your vehicle and its
three- way catalytic converter sys-tem best.

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,

repairing?
For scheduled maintenance informa-
tion, please refer to the separate
ºOwner 's Manual Supplement/Main-
tenance Scheduleº. Maintenance requirements
Your Toyota vehicle has been designed for
fewer maintenance requirements with long-
er service intervals to save both your time
and money. However, each regular mainte-
nance, as well as day- to- day care, is
more important than ever before to ensure
smooth, trouble- free, safe, and economical
drivings.
It is the owner 's responsib
ility to make
sure the specified maintenance, including
general maintenance service is performed.
Note that both the new vehicle and emis-
sion control system warranties specify that
proper maintenance and care must be per-
formed. See Owner 's Guide, Owner 's
Manual Supplement or Warranty Booklet
for complete warranty information.
General maintenance
General maintenance items are those day-
to- day care practices that are important to
your vehicle for proper operation. It is the
owner 's responsib ility to ensure that the
general maintenance items are performed
regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost. Scheduled maintenance
The scheduled maintenance items listed in
the ºOwner 's Manual Supplement/Mainte-
nance Scheduleº are those required to be
serviced at regular intervals.

It is recommended that any replacement
parts used for maintenance or for the
repair of the emission control system
be Toyota supplied.
The owner may elect to use non- Toyota
supplied parts for replacement pur-
poses without invalidating the emission
control system warranty. However, use
of replacement parts which are not of
equivalent quality may impair the effec-
tiveness of the emission control sys-
tems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair es-
tablishment or individual without invali-
dating this warranty. See Owner's
Guide, Owner 's Manual Supplement or
Warranty Booklet for complete warranty
information.
