The three±way catalytic converter/warm up three±way catalytic
converter is an emission control device 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.
NOTICE
A large amount of unburned gases flowing into the three±way catalytic\
converter/warm up 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/warm up three±way catalytic converter.
 Do not allow the engine to run at idle speed for more 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 is moving.

STARTING AND DRIVING133

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 extremely high three±way
catalytic converter/warm up 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/warm
up three±way catalytic converter system best.
 To ensure that the three±way catalytic converter /warm up 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 separate ºOwner's Manual Supplement/
Maintenance Scheduleº.
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. If you must drive with the trunk lid open
to accommodate a large object, close the windows, open all
the dashboard vents and have the heating or cooling system
deliver fresh air into the vehicle by turning the fan to high
speed with the air intake control button in the OUTSIDE
AIR mode.

IN CASE OF AN EMERGENCY163
NOTICE
Do not pull± or push±start the vehicle. It may damage the vehicle o\
r cause
a collision when the engine starts. Also the three±way catalytic conv\
erter
/ warm up three±way catalytic converter may overheat and become a fir\
e
hazard.
If the engine turns over at its normal speed but will not start ±
1. The engine may be flooded because of repeated cranking. See º(b) Star\
ting
a flooded engineº for further instructions.
2. If the engine still will not start, it needs adjustment or repair. Call a Lexus
dealer, Roadside Assistance or Customer Service Assistance. (See
ºForewordº.)
(b) Starting a flooded engine
If the engine will not start, your engine may be flooded because of
repeated cranking.
If this happens, turn the key to ºSTARTº with the accelerator pedal held down.
Continue this operation for 30 seconds and then stop cranking. Then try
starting the engine with your foot off the accelerator pedal.
If the engine does not start after 30 seconds of cranking, release the key\
, wait
a few minutes and try again.
If the engine still will not start, it needs adjustment or repair. Call a Lexus
dealer. Roadside Assistance or Customer Service Assistance. (See
ºForewordº.)
NOTICE
Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.

ENGINE195
FUEL
Fuel type
Your vehicle must use only unleaded gasoline.
To help prevent gas station mixups, your Lexus has a smaller fuel tank
opening. The special nozzle on pumps with unleaded fuel will fit it, but the
larger nozzle on pumps with leaded gas will not.
At a minimum, the gasoline you use should meet the specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5±M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three±way catalytic converter/warm up three±way catalytic converter to
lose its effectiveness and the emission control system to function
improperly. Also, this can increase maintenance costs.
Octane rating
Select Octane Rating 87 (Research Octane Number 91) or higher. For
improved vehicle performance, the use of premium unleaded gasoline
with an Octane Rating of 91 (Research Octane Number 96) or higher is
recommended.
Use of unleaded fuel with an Octane Rating or Research Octane Number
lower than stated above will cause persistent heavy knocking. If it is sever\
e,
this will lead to engine damage. If your engine knocks ...
If you detect heavy knocking even when using the recommended fuel, or if\
you hear steady knocking while holding a steady speed on level roads, consu\
lt
your Lexus dealer.
However, now and then, you may notice light knocking for a short time while
accelerating or driving up hills. This is no cause for concern.
Gasolines containing detergent additives
Lexus recommends use of gasolines that contain detergent additives to
avoid build±up of engine deposits.
For further details, ask your Lexus dealer or a local gasoline retailer.
Improved gasolines
The American Automobile Manufacturers Association (AAMA) has
developed a specification of improved gasolines. The AAMA
specification offers optimal fuel information for better vehicle
performance and better protection of your engine.
Lexus recommends the use of gasolines that meet the AAMA specification,
if available, for improved drivability and emission control system.
