THREE±WAY CATALYTIC
CONVERTER

STARTING AND DRIVING
274
31E085
The three±way catalytic converters are emission
control devices installed in the exhaust system.
It looks somewhat like a muffler, but its 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.

STARTING AND DRIVING
275
NOTICEA large amount of unburned gases flowing intothe three±way catalytic converter may cause it tooverheat 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 tomisfire, creating an excessive load on thethree±way catalytic converter.
Do not allow the engine to run at idle speed formore than 20 minutes.
Avoid racing the engine.
Do not push±start or pull±start your vehicle.
Do not turn off the ignition while the vehicle ismoving.
Keep your engine in good running order.Malfunctions in the engine electrical system,electronic ignition system/distributor ignitionsystem or fuel system could cause anextremely high three±way catalytic converter
temperature.
If the engine becomes difficult to start or stallsfrequently, take your vehicle in for a check±upas soon as possible. Remember, your Lexusdealer knows your vehicle and its three±waycatalytic converter system best.

STARTING AND DRIVING
276
To ensure that the three±way catalytic
converter and the entire emission controlsystem operate properly, your vehicle mustreceive the periodic inspections required bythe Lexus Maintenance Schedule. Forscheduled maintenance information, refer tothe ªOwner's Manual
Supplement/Maintenance Scheduleº.ENGINE EXHAUST CAUTION

STARTING AND DRIVING
277
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.

STARTING AND DRIVING
278
To allow proper operation of your vehicle's
ventilation system, keep the inlet grilles in front
of the windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive
with the windows open and the trunk lid closed.
Have the cause immediately located and
corrected.BEFORE STARTING THE ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint
height and steering wheel angle.
3. Adjust the inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.
Remember to check that the service reminder indicators
function when turning the key to ªONº, and check the fuel
gauge to see that you have sufficient fuel.
