A new disc may have rough edges on its inner and outer
perimeter. Remove the rough edges by pressing the side
of a ball±point pen or pencil against the inner and outer
perimeter of the disc as shown.
If you continue to play a disc with rough edges, flakes will fall
on to the signal side of the disc and cause sound skipping or
other problems.

Do not allow the disc to bear any fingerprints, stickers or
pen marks on the surfaces.
Hold the disc only on the edge or center hole.
When not in use, take the disc out of the player, put it back
into its case and store it away from dust, heat, damp and
direct sunlight.
Leaving discs on the dashboard in the sun may damage or
warp them.

THREE±WAY CATALYTIC CONVERTER

STARTING AND DRIVING
209
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.

STARTING AND DRIVING
210
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.
 Avoid racing the engine.
 Do not push±start or pull±start your vehicle.
Do not turn off the ignition 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
separate ºOwner's Manual Supplement/
Maintenance Scheduleº.

STARTING AND DRIVING
211
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.

STARTING AND DRIVING
212
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 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 ºONº, and check the fuel
gauge to see that you have sufficient fuel.
