THREE-WAY CATALYTIC
CONVERTER
The 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 gas 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 gas 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 / distributor 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.

STARTING AND DRIVING
105

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.
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.

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 and headrest height.
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 ignition key to “ON”, and check the
fuel gauge to see that you have sufficient fuel.

PARKING BRAKE
Unlock
Set
Release
To set: Pull up the lever.
To release: Pull up the lever slightly, press the thumb
button, then lower the lever.
Before leaving your vehicle, firmly apply the parking brake.
CAUTION:
Before driving, make sure the parking brake is fully
released and that the parking brake reminder light is off.
HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in “P”. If you need to restart the engine
while the vehicle is moving, put the selector lever in “N”. A
starter safety device will prevent the starter from operating if
the selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until you are
ready to drive off.
Starting the engine
Before starting the engine, be sure to follow the instructions in
“Before cranking”.
Normal starting procedure
The multiport fuel injection system / sequential multiport fuel
injection system in your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot
engine as follows:

STARTING AND DRIVING
”P” (Park) position
”N” (Neutral) position
11 0Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This means you
can only shift out of “P” position when the brake pedal is
depressed (with the ignition switch in “ON” position and the
lock release button pressed in.)
Correct use of the automatic transmission is explained in the
following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the “2” and “L” positions
(d) Backing up
(e) Parking
(f) Good driving practice
(g) If you cannot shift the selector lever out of “P” position
(h) If the “O / D OFF” indicator light flashes
(a) Normal driving
1. Start the engine as instructed in “How to start the
engine” on page 107.
The transmission must be in “P” or “N”. The engine will not start
in “R”, “2”. “L” or “D” position even if the ignition key is turned
to “START”.
”NORM” (Normal) position
”PWR” (Power) position
Indicator light
2. Set the driving pattern selector switch to the “NORM”
position.
Your transmission has a driving pattern selector switch which
allows you to select either “NORM” or “PWR” to suit your
driving condition. For ordinary driving, Lexus recommends that
you use the “NORM” position to improve fuel economy.
3. For more powerful acceleration and sporty driving, use
the “PWR” position.
In the “PWR” position, the “ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the
“NORM” position.

4. Set the overdrive switch to the ON position.
Always set the overdrive switch to the ON position for improved
fuel economy and quiet driving. (See “(b) Using engine
braking” and “(f) Good driving practice” for exceptions.)
5. With your foot holding down the brake pedal, shift the
selector lever to “D”.CAUTION:
Never put your foot on the accelerator pedal while
shifting.
6. Release the parking brake and brake pedal. Depress the
accelerator pedal slowly for smooth starting.
The vehicle will start in the first gear and automatically shift to
the most suitable gear for the running conditions, such as the
vehicle speed, hill climbing, hard towing, etc. However, while
the engine coolant temperature is low and the vehicle is
traveling at low speed, the transmission will not shift into the
overdrive gear even with the overdrive switch on.
In “D” position, the automatic transmission system will select
the most suitable gear for the running conditions such as hill
climbing, hard towing, etc.
If you need to accelerate rapidly while driving, push the
accelerator pedal all the way to the floor. The transmission will
automatically downshift to the third, second or first gear,
according to the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see “(b) Using engine braking”.
