Using your audio system: some basics
This section describes some of the basic features of the Lexus
audio system. Some informat ion may not pertain to your
system.
Your audio system works when the ignition key is in the “ACC”
or “ON” position.
NOTICE
To prevent the battery from being discharged, do not
leave the audio system on longer than necessary when
the engine is not running.

this knob to adjust the volume.
The system turns on in the last mode used.
21X507a
Push “AM·SAT”, “FM”, “TAPE” or “DISC” to turn on that
mode. The selected mode turns on directly.
Push these buttons if you want to switch from one mode to
another.
If the tape or CD is not set, the cassette player or CD player
does not turn on.
You can turn off the cassette player by ejecting the cassette

“LOAD” and the CD door opens.
4. Repeat this procedure until you insert all the CDs.
To cancel the operation, push the “LOAD” or “DISC” button.
If you do not insert the CDs within 15 seconds after pushing the
“LOAD” button and “LOAD” is displayed, the operation will be

THREEWAY CATALYTICCONVERTERS
31X001f
Threeway catalytic converters are emission control
devices installed in the exhaust system.
The 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
threeway 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 threeway catalytic
converter.
 Do not allow the engine to run at idle speed for more
than 20 minutes.
 Avoid racing the engine.
 Do not pushstart or pullstart 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, electric
ignition system or fuel system could cause an
extremely high threeway catalytic converter
temperature.
 If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a checkup as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its threeway catalytic
converter system best.

STARTING AND DRIVING
256
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 the 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 “ON”, and check the fuel
gauge to see that you have sufficient fuel.
IGNITION SWITCH
31X002a
“START” Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page 258.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the “ON” position if the engine
is not running. The battery will discharge and the
electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off.

STARTING AND DRIVING
257
If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
31X003a
“LOCK” Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from “ACC” to the “LOCK” position, you must
put the transmission selector lever in the “P” position.
Once you remove the key, the engine immobilizer system is
automatically set. See “Engine immobilizer system” on page
11 .
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.
It is not a malfunction if the needles on all meters and gauges
move slightly when the key is turned to the “ACC”, “ON” or
“START” position.
Several hours after the engine is turned off, you may hear a
sound coming from underneath the luggage compartment for
several minutes. This is normal operation and does not
indicate a malfunction. (See page vii.)

PARKING BRAKE
31X065
1To set: Pull up the lever. For better holding power,
first depress the brake pedal and hold it while setting
the parking brake.
2 To release: Pull up the lever slightly (1), press the
lock release button (2), and lower the lever (3).
Before leaving your vehicle, firmly apply the parking brake. For
better holding power, first depress the brake pedal and hold it
while setting 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
Cranking hold function
Once you turn the ignition key to “START” position and release
it, the cranking hold function continues to crank the engine in
“ON” position until it starts.
The function stops cranking the engine after about 25 seconds
maximum if the engine has not started yet. When you crank
the engine again, wait a few seconds and restart it.
If you hold the key in “START” position, the function will keep
cranking for about 30 seconds maximum.
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 driving
off.

STARTING AND DRIVING
259
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:
With your foot off the accelerator pedal, turn the ignition key to
“START” position, then release it.
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 “If your vehicle will not start” on page 334.
NOTICE
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls
frequently, have the engine checked immediately.
AUTOMATIC TRANSMISSION
Your 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 ( )
