light flashes and buzzer comes on if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
stays flashing and the buzzer stops after about 4 to 8 seconds.
(c) SRS Airbag Warning Light
This indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the SRS airbag system is operating
properly.
The SRS airbag warning light system monitors the airbag
sensor assembly, inflators, warning light, interconnecting
wiring and power sources.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the
warning light system. Contact your Lexus dealer as soon as
possible to service the vehicle.

The light does not come on as described above or remains
on.

The light comes on while driving.
(d) Discharge Warning Light
This light warns that the battery is being discharged.
If it comes on while you are driving, stop the vehicle, turn off
the engine, and check for the cause. Look first at the engine
drive belt.

If it is loose or broken, the generator will not charge the
battery properly.

If the belt is O.K., there is a problem somewhere in the
charging system.
The engine ignition will continue to operate, however, until
the battery is discharged. Turn off the air conditioning,
blower, radio, etc., and drive directly to the nearest Lexus
dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken
or loose.

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.

AIR CONDITIONING AND AUDIO
191


Fading and drifting:
FM range is limited to about 40 km (25 miles), except for
some high power stations.
If a vehicle is moving away from the desired station's
transmitter, the signal will tend to fade and/or drift. This
phenomenon is more noticeable with FM than with AM,
and is accompanied by distortion.
Fading and drifting can be minimized to a certain degree
by careful attention to fine tuning, or you should retune the
radio to another stronger station.

Static and Fluttering:
When the line±of±sight link between a transmitter and
vehicle is blocked by large buildings or the like, the radio
sound may be accompanied by static or fluttering because
of the characteristic of FM. In a similar effect, a fluttering
noise is sometimes heard when driving along a tree±lined
road.
This static and fluttering can be reduced by adjusting the
tone control for greater bass response until the disturbance
has passed.

Multipath:
Because of the reflecting characteristics of FM, direct and
reflected signals may reach the antenna at the same time
(multipath) and cancel each other out. As a vehicle moves
through these electronic dead spots, the listener may hear
a momentary flutter or loss of reception.

Station swapping:
When two FM stations are close to each other, and an
electronic dead spot, such as static or multipath area,
interrupts the original signal, sometimes the stronger
second signal will be selected automatically until the
original one returns. This swapping can also occur as you
drive away from the selected station and approach another
station with a stronger signal.

Cassette tape player operation
(a) Playing a cassette tape
1. Put the cassette into the slot, with the tape side to the right
and lightly push it in. The tape player will grasp the cassette
and slide it into place to play. If the radio is on when the
cassette is inserted, the radio will automatically turn off.
If the cassette is already in the slot, push the
(TAPE)
button.
At this time, ºTAPEº will appear on the display.
The tape player can also be turned on by pushing the
ºPWR.VOLº knob if the tape player was being used when the
system was turned off.
When a metal or chrome equivalent tape is inserted, the player
will automatically adapt to it and ºMETALº will appear on
the display.
2. If using a tape recorded with Dolby
 NR*, push the right
side of the ( B C) button to select the Dolby B
NR or Dolby C NR mode. The display will indicate which
Dolby noise reduction system is operating.
The Dolby B NR mode reduces tape noise by about 10 dB.
The Dolby C NR mode reduces tape noise by another 10 dB
or about 20 dB total. For best sound reproduction, select the
same NR mode that was used to record the tape. To play a tape
recorded without Dolby NR*, push the button until the Dolby
NR indicator disappears.
