THREE−WAY CATALYTIC
CONVERTERS
G31042
GS430
G31043
GS300Three−way catalytic converters are emission control
devices installed in the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
CAUTION
Keep people and combustible materials away from
the exhaust pipe while the engine is running. The
exhaust gas is very hot.
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:
Use only unleaded gasoline.
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.
Do not allow the engine to run at idle speed for more
than 20 minutes.
STARTING AND DRIVING
341 Avoid racing the engine.
Do not push−start or pull−start your vehicle.
Do not turn off the engine while the vehicle is moving.
Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high three−way catalytic converter
temperature.
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.
To ensure that the three−way catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
“Owner’s Manual Supplement / Scheduled
Maintenance”.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains
carbon monoxide, which is a colorless and odorless
gas. It can cause unconsciousness or even death.
Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be
drawn into the vehicle.
