1.8 L 4−cylinder (2ZZ−GE) engine
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
D Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
D 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 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, creat-
ing 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.
