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.

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.

IN CASE OF AN EMERGENCY
337
IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have
followed the correct starting procedure instructions in
ªHow to start the engineº on page 281 and that you have
sufficient fuel. Since your vehicle is equipped with the
engine immobiliser system, also check whether the
other keys will start the engine. If they work, your key
may be broken. Have the key checked at your Lexus
dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ªKeysº on page 7.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior
light.
3. If the light is out, dim or goes out when the starter is
cranked, the battery is discharged. You may try jump
starting. See ª(c) Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it
needs adjustment or repair. Call a Lexus dealer,
Roadside Assistance or Customer Service Assistance.
(See ªForewordº.)
NOTICE
Do not pull± or push±start the vehicle. It may damage the vehicle or cause a collision when theengine starts. Also the three±way catalyticconverter / warm up three±way catalytic convertermay overheat and become a fire 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 ª(b) Starting 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 ªForewordº.)

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 standard 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 catalyticconverter to lose its effectiveness and theemission 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 severe, 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, consult 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 the use of gasoline that contain
detergent additives to avoid build±up of engine
deposits.
For further details, ask your Lexus dealer or a local
gasoline retailer.
Quality gasoline
Automobile manufacturers in U.S., Europe and
Japan have developed a specification for quality
fuel named W orld±Wide Fuel Charter (WWFC) that is
expected to be applied world wide. The WWFC
consists of three categories that depend on
required emission levels. In the U.S., category 3 has
been adopted. The WWFC improves air quality by
providing for better emissions in vehicle fleets, and
