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.

1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3.Manual transmission : Press the clutch pedal to the floor
and shift the transmission into neutral. Hold the clutch pedal to
the floor until the engine is started. A starter safety device will
prevent the starter from operating if the clutch pedal is not fully
depressed.
Automatic transmission: Put the selector lever in ªPº. If you
need to restart the engine while the vehicle is moving, put the
selector lever in ªNº. A starter safety device will prevent the
starter from operating if the selector lever is in any drive
position.
4. For automatic transmission only :Depress the brake
pedal and hold it to the floor until driving off.
Starting the engine
Before starting the engine, be sure to follow the instructions in
ªBefore crankingº.
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:
With your foot off the accelerator pedal, crank the engine by
turning the key to ªSTARTº. Release it when the engine starts. Engine should be warmed up by driving, not in idle. For
warming up drive with smoothly turning engine until engine
coolant temperature is within normal range.
If the engine stalls ...
Simply restart it , using the correct procedure given in normal
starting.
If the engine will not start
See ªIf your vehicle will not startº on page 281.
NOTICE
Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to start or stallsfrequently, have the engine checked immediately.

2. Set the driving pattern selector switch to the ªNormalº
position.
Your transmission has a driving pattern selector switch which
allows you to select ªPowerº, ªNormalº or ªSnowº mode \
to suit
your driving condition. For ordinary driving, Lexus
recommends that you use the ªNormalº position to improve fuel
economy.
3. For more powerful acceleration and sporty driving, use
the ªPowerº position.
In the ªPowerº position, the ªECT PWRº 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
ªNormalº position.
For ªSnowº mode, see ªElectronic Throttle Control
Systemº on page 260.

4. With your foot holding down the brake pedal, shift the
selector lever to ªDº.
Always use the ªDº position to improve fuel economy and quiet
driving. In this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is
low, the transmission will not shift into the overdrive gear even
in the ªDº position. (See ª(c) Using engine brakingº and \
ª(g)
Good driving practiceº for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while

MANUAL TRANSMISSION
SV31034
The shift pattern is the conventional pattern shown above.
CAUTION
The shift lever knob can become extremely hot after
parking under the sun.
Press the clutch pedal down fully while shifting, and then
release it slowly. Do not rest your foot on the pedal while
driving, because it will cause clutch trouble. Do not use the
clutch to hold the vehicle when stopped on an uphill grade ±
use the parking brake.
Upshifting too soon or downshifting too late will cause lugging,
and possibly pinging. Regularly revving the engine to
maximum speed in each gear will cause excessive engine
wear and high fuel consumption.Recommended shifting speeds
The transmission is fully synchronized and upshifting or
downshifting is easy.
For the best compromise between fuel economy and vehicle
performance, you should upshift or downshift at the following
speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
Downshift to the appropriate gear if acceleration is needed
when you are cruising below the above downshifting speeds.
Upshifting too soon or downshifting too late will cause lugging,
and possibly pinging. Regularly revving the engine to
maximum speed in each gear will cause excessive engine
wear and high fuel consumption.
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each gear: gear km/h (mph)1 56 (35)
2 98 (61)
3 145 (91)
