INFORMATION BEFORE DRIVING YOUR TOYOTA -> Three-way catalytic converters for Your Toyota Prius 4 Door Second Generation (2004-2009)

Three−way catalytic converters  
NOTICE  
z 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 the  
Toyota Maintenance Schedule. For  
scheduled maintenance information,  
refer to the “Scheduled Maintenance  
Guide” or “Owner’s Manual Supple-  
ment”.  
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.  
The three−way catalytic converters are  
emission control devices installed in  
the exhaust system.  
z Do not turn off the ignition while  
the vehicle is moving.  
Its purpose is to reduce pollutants in the  
exhaust gas.  
z Keep your engine in good running  
order. Malfunctions in the engine  
electrical system, electronic ignition  
system/distributor ignition system  
or fuel system could cause an ex-  
tremely high temperature.  
CAUTION  
Keep people and combustible mate-  
rials away from the exhaust pipe  
while the engine is running. The  
exhaust gas is very hot.  
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 Toyota  
dealer knows your vehicle and its  
three−way catalytic converter sys-  
tem best.  
Do not drive, idle or park your ve-  
hicle over anything that might burn  
easily such as grass, leaves, paper  
or rags.
