If the system is used for ventilation, heating in dry weather or
removing frost or exterior fog on the windshield, turn the air
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for year±round
automatic temperature control including cooling and
dehumidifying operation.

THREE±WAY CATALYTICCONVERTER
SV31040
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.
NOTICE
A large amount of unburned gases flowing into the three±way catalytic converter may cause it to overheatand create a fire hazard. To prevent this and otherdamage, observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low fuel level; runningout of fuel could cause the engine to misfire, creatingan excessive load on the three±way catalyticconverter.
Do not allow the engine to run at idle speed for morethan 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 or fuel system could cause
an extremely high three±way catalytic converter temperature.
If the engine becomes difficult to start or stallsfrequently, take your vehicle in for a check±up assoon as possible. Remember, your Lexus dealer
knows your vehicle and its three±way catalyticconverter system best.

To ensure that the three±way catalytic converter and
the entire emission control system operate properly,your vehicle must receive the periodic inspectionsrequired by the Lexus Maintenance Schedule . Forscheduled maintenance information, refer to theªOwner's Manual Supplement/ScheduledMaintenanceº.ENGINE EXHAUST CAUTION
CAUTION
 Avoid i nhaling 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 or back door closed while driving.
An open or unsealed trunk lid or back door may
cause exhaust gases to be drawn into the vehicle.

closed. Have the cause immediately located and
corrected.BEFORE STARTING THE ENGINE

TRACTION CONTROL SYSTEM
(With vehicle stability control system)
The traction control system automatically helps prevent
the spinning of rear wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to ªONº, the system
automatically turns on.
CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power against rear wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
