AIR CONDITIONING AND AUDIO
187
To prevent the battery from being discharged, do not leave
the car audio on longer than necessary when the engine
is not running.
To ensure the correct audio system operation:


Be careful not to spill beverages over the audio system.

Do no put anything other than a cassette tape or CD
magazine into the cassette tape slot or CD changer.

The use of cellular phone inside or near the vehicle
may cause a noise from the speakers of the audio
system which you are listening to. However, this does
not indicate a malfunction.
You can listen to the car audio when the ignition key is at
ºONº or ºACCº. However, if the engine is not running,
the key must be in the ºACCº position.
You can adjust the brightness of the display. See ºInstrument
panel light control on page 64 for details.
Audio operation is described in detail on the following pages:

Radio operation ± See page 187.

Cassette tape player operation ± See page 192.

Compact disc player operation ± See page 196.
Radio operation
(a) Listening to the radio
1. Push the
(AM) or (FM1/2) button to turn the
radio on and select either an AM or FM broadcast.
ºAMº, ºFM1º or ºFM2º will appear on the display.
The radio can also be turned on by pushing the ºPWR.VOLº
knob if the radio was being used when the system was turned
off.
2. Turn the ºPWR.VOLº knob to adjust the volume.
3. Tune in the desired station. (See º(b) Selecting a stationº.)
The radio will change automatically to stereo reception when
an FM stereo broadcast is being received. At the same time
ºSTº will appear on the display. When the receiving signal
gets weak, the channel separation will automatically be
reduced for lowest noise. If the signal becomes extremely
weak, the radio will switch over to monaural reception.
4. Adjust the tone and sound balance. (See º(d) Adjusting the
toneº and º(e) Adjusting the sound balanceº.)
5. To turn the radio off, push the ºPWR.VOLº knob.

AIR CONDITIONING AND AUDIO
190Radio operating tips
The antenna automatically extends when the radio and
ignition are turned on and retracts when either is turned off.
CAUTION
Before extending the antenna, confirm that no one is close
enough to get injured.
NOTICE
To prevent damage to the antenna, make sure it is
retracted before running your vehicle through an
automatic car wash.
FM reception tips
A vehicle is not an ideal place to listen to a radio. Because it
moves, reception conditions are constantly changing.
Buildings, terrain, signal distance and noise from other
vehicles are all working against good reception. Some
conditions of FM may appear to be problems when they are
not. The following characteristics are completely normal for
a given reception area, and they do not indicate any problem
with the radio itself.

Compact disc player operation
The compact disc player of this system is provided with an
automatic changer which can play selected discs or 6 discs
continuously. The player is mounted in the trunk, on the right

ºRANDOMº button: Use for automatic program selection
and play by the system.
When
the
(RANDOM) button is pushed on the right
side, ºRNDº appears on the display and the system selects a
program on the disc which is set and plays it. To cancel it,
push the button once again.
When a program is skipped or the system is inoperative, push
the
(CD) button to reset.
(f) If the player malfunctions
If ºWAITº appears on the display, audio signals of the disc
cannot be read or the system has trouble. Push the

button once again.
If the player does not operate, check that the disc surface is not
soiled or damaged. If the disc is O.K., the following two
causes are possible.

Condensation may have occurred on the internal
mechanism of the player.
Open the trunk to let air circulate.

The temperature of the player's internal mechanism is
raised because of high external temperature.
Remove the magazine from the player to cool it.
If the player still does not operate, take it to your Lexus dealer. Compact disc player operating tips

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.
