NOTICE
To ensure the correct audio system operation:
Be careful not to spill beverages over the audiosystem.
Do not put anything other than a cassette tapeor CD magazine into the cassette tape slot or
CD changer.
The use of cellular phone inside or near thevehicle may cause a noise from the speakers of
the audio system which you are listening to. However, this does not indicate a malfunction.
Radio reception
Usually, the problem with radio reception does not mean
there is a problem with your radio ± it is just the normal
result of conditions outside the vehicle.
For example, nearby buildings and terrain can interfere
with FM reception. Power lines or telephone wires can
interfere with AM signals. And of course, radio signals
have a limited range, and the farther you are from a
station, the weaker its signal will be. In addition,
reception conditions change constantly as your vehicle
moves.
Here are some common reception problems that
probably do not indicate a problem with your radio:
FM
Fading and drifting stations ± Generally, the effective
range of FM is about 40 km (25 miles). Once outside this
range, you may notice fading and drifting, which
increase with the distance from the radio transmitter.
They are often accompanied by distortion.
Multi±path ± FM signals are reflective, making it
possible for two signals to reach your antenna at the
same time. If this happens, the signals will cancel each
other out, causing a momentary flutter or loss of
reception.
Static and fluttering ± These occur when signals are
blocked by buildings, trees, or other large objects.
Increasing the bass level may reduce static and

fluttering.
Station swapping ± If the FM signal you are listening to
is interrupted or weakened, and there is another strong
station nearby on the FM band, your radio may tune in
the second station until the original signal can be picked
up again.
AM
Fading ± AM broadcasts are reflected by the upper
atmosphere ± especially at night. These reflected
signals can interfere with those received directly from
the radio station, causing the radio station to sound
alternately strong and weak.
Station interference ± When a reflected signal and a
signal received directly from a radio station are very
nearly the same frequency, they can interfere with each
other, making it difficult to hear the broadcast.
Static ± AM is easily affected by external sources of
electrical noise, such as high tension power lines,
lightening, or electrical motors. This results in static.
Caring for your cassette player and tapes
For high performance from your cassette player and
tapes:
Clean the tape head and other parts regularly.
 A dirty tape head or tape path can decrease sound
quality and tangle your cassette tapes. The easiest
way to clean them is by using a cleaning tape. (A wet
type is recommended.)

STARTING AND DRIVING
277
ºSTARTº ± Starter motor on. The key will return to
the ºONº position when released.
For starting tips, see page 280.
ºONº ± Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the ºONº position if the
engine is not running. The battery will dischargeand the electronic ignition system/distributorignition system could be damaged.
ºACCº ± Accessories such as the radio operate, but
the engine is off.
If you leave the key in the ºACCº or ºLOCKº position and
open the driver's door, a buzzer will remind you to
remove the key.*
NOTE: *The volume or interval of beep sound can bechanged. Ask your Lexus dealer for details.
