THREE–WAY CATALYTIC
CONVERTER
Three–way catalytic converters are emission control
devices installed in the exhaust system.
The three–way catalytic converter located at the confluence
of exhaust pipes looks somewhat like a muffler, but its
purpose is to reduce pollutants in the exhaust gas.
CAUTION
!
S
Keep people and combustible materials away from
the exhaust pipe while the engine is running. The
exhaust gas is very hot.
S
Do not drive, idle or park your vehicle 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:
S
Use only unleaded gasoline.
S
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.
S
Do not allow the engine to run at idle speed for
more than 20 minutes.
S
Avoid racing the engine.
S
Do not push–start or pull–start your vehicle.
S
Do not turn off the ignition while the vehicle is
moving.
S
Keep
your
engine
in
good
running
order.
Malfunction in the engine electrical system,
electronic
ignition
system/distributor
ignition
system or fuel system could cause an extremely
high three–way catalytic converter temperature.
S
If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check–up as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its three–way catalytic
converter system best.
