Three-way catalytic converter
The three-way catalytic converter is
an emission control device installed in
the exhaust system.
It looks somewhat like a muffler, but its
purpose is to reduce pollutants in the ex-
haust gas.
CAUTION
!
D Keep people and combustible ma-
terials away from the exhaust pipe
while the engine is running. The ex-
haust gas is very hot.
D Do not idle or park your vehicle
over anything that might burn easi-
ly such as grass, leaves, paper or
rags.

A large amount of unburned gases
flowing into the three-way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
z Use only unleaded gasoline.
z Do not drive with an extremely low
fuel level; running out of fuel
could cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
z Do not allow the engine to run at
idle speed for more than 20 min-
utes.
z Avoid racing the engine.
z Do not push-start or pull-start
your vehicle.
z Do not turn off the ignition while
the vehicle is moving.
z Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-
tion system/distributor ignition
system or fuel systems could
cause an extremely high three-
way catalytic converter tempera-
ture.

NOTICE
z If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your To-
yota dealer knows your vehicle
and its three-way catalytic con-
verter system best.
z To ensure that the three-way cata-
lytic converter and the entire
emission control system operate
properly, your vehicle must re-
ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte-
nance information, refer to the
separate "Owner's Manual Sup-
plement/Maintenance Schedule".
