IF THE SATELLITE RADIO TUNER MALFUNCTIONS
When problems occur with the XM tuner, a message will appear on the screen. Refer-
ring to the table below to identify the pr oblem, take the suggested corrective action.
MessageExplanation
“Radio XM Check
Antenna”
The XM antenna is not connected . Check whether the XM antenna
cable is attached securely.
A short circuit occurs in the ant enna or the surrounding antenna ca-
ble. See a Lexus certifie d dealer for assistance.
“Radio XM Ch
Unauthorized”
You have not subscribed to XM Satellite Radio. The radio is being
updated with the latest encryption code. Contact XM Satellite Radio
for subscription information. When a contract is canceled, you can
choose “CH 000” and al l free-to-air channels.
The premium channel you selected is not authorized. Wait for about
2 seconds until the radio returns to the previous channel or “CH
001”. If it does not change auto matically, select another channel. To
listen to the premium channel, contact XM Satellite Radio.
“Radio XM No Signal”The XM signal is too weak at the current location. Wait until your ve-
hicle reaches a location with a stronger signal.
“Loading”The unit is acquiring audio or program information. Wait until the unit
has received the information.
“Radio XM Channel
Off Air”The channel you selected is not br oadcasting any programming. Se-
lect another channel.
-----There is no song/program title or artist name/feature associated with
the channel at that time. No action is required.
“Radio XM Ch
Unavailable”The channel you selected is no longer available. Wait for about 2 sec-
onds until the radio returns to the previous channel or “CH 001”. If it
does not change automaticall y, select another channel.

CAUTION
●Do not operate the player’s controls or connect to the Bluetooth® audio system while driv-
ing.
●Your audio unit is fitted with Bluetooth® antennas. People with implantable cardiac pace-
makers, cardiac resynchronization therapy- pacemakers or implantable cardioverter
defibrillators should mainta in a reasonable distance between themselves and the
Bluetooth
® antennas. The radio wa ves may affect the operation of such devices.
●Before using Bluetooth® devices, users of any electrical medical device other than implant-
able cardiac pacemakers, cardiac resynchron ization therapy-pacemakers or implantable
cardioverter defibrillators shou ld consult the manufacturer of the device for information
about its operation under the influence of radio waves. Radio waves could have unexpected
effects on the operation of such medical devices.
NOTICE
●Do not leave your portable player in the vehicl e. In particular, high temperatures inside the
vehicle may damage the portable player.

AUDIO/VISUAL SYSTEM
6. TIPS FOR OPERATING THE AUDIO/VISUAL SYSTEM
1. OPERATING INFORMATION
Fading and drifting stations: Generally, the
effective range of FM is about 25 miles (40
km). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter.
They are often accompanied by distortion.
Multi-path: FM signals are reflective, mak-
ing it possible for 2 signals to reach the vehi-
cle’s 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 sig-
nals are blocked by buildings, trees or other
large objects. Increasing the bass level may
reduce static and fluttering.
Station swapping: If th e FM signal being lis-
tened to is interrupted or weakened, and
there is another strong station nearby on
the FM band, the radio may tune in the sec-
ond station until the original signal can be
picked up again.
Fading: AM broadcasts are reflected by the
upper atmosphere — especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound al-
ternately strong and weak.
Station interference: When a reflected sig-
nal and a signal received directly from a ra-
dio station are very nearly the same
frequency, they can interfere with each oth-
er, making it difficult to hear the broadcast.
Static: AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, ligh tening or electrical
motors. This results in static.
NOTICE
●To avoid damage to the audio/visual sys-
tem:
• Be careful not to spill beverages over the audio/visual system.
• Do not put anything other than an appropriate disc into the disc slot.
INFORMATION
●The use of a cellular phone inside or near
the vehicle may cause a noise from the
speakers of the audio/visual system which
you are listening to. However, this does
not indicate a malfunction.
RADIO
Usually, a problem with radio reception
does not mean there is a problem with
the radio — it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and ter-
rain can interfere with FM reception.
Power lines or phone wires can interfere
with AM signals. And of course, radio
signals have a limited range. The farther
the vehicle is from a station, the weaker
its signal will be. In addition, reception
conditions change constantly as the ve-
hicle moves.
Here, some common reception prob-
lems that probably do not indicate a
problem with the radio are described.

1. PHONE OPERATION (HANDS-FREE SYSTEM FOR CELLULAR PHONES)

PHONE
2. SOME BASICS
The hands-free system enables calls to
be made and received without having to
take your hands off the steering wheel.
This system supports Bluetooth
®.
Bluetooth
® is a wireless data system
that enables cellular phones to be used
without being connected by a cable or
placed in a cradle.
The operating procedure of the phone is
explained here.
CAUTION
●While driving, do not use a cellular phone
or connect the Bluetooth® phone.
●Your audio unit is fitted with Bluetooth®
antennas. People with implantable car-
diac pacemakers, cardiac resynchroniza-
tion therapy-pacemakers or implantable
cardioverter defibrill ators should main-
tain a reasonable distance between
themselves and the Bluetooth
® antennas.
The radio waves may affect the operation
of such devices.
●Before using Bluetooth® devices, users
of any electrical medical device other
than implantable cardiac pacemakers,
cardiac resynchronization therapy-pace-
makers or implantable cardioverter
defibrillators should consult the manufac-
turer of the device for information about
its operation under th e influence of radio
waves. Radio waves could have unex-
pected effects on the operation of such
medical devices.
NOTICE
●Do not leave your cellular phone in the
vehicle. The temperature inside may rise
to a level that coul d damage the phone.
INFORMATION
●If your cellular phone does not support
Bluetooth®, this system cannot function.
●In the following conditions, the system
may not function:
• The cellular phone is turned off.
• The current position is outside the com-
munication area.
• The cellular phone is not connected.
• The cellular phone has a low battery.
●When using Bluetooth® audio and
hands-free system at the same time, the
following problems may occur:
• The Bluetooth
® connection may be cut.
• Noise may be heard on the Bluetooth
®
audio playback.
REGISTERING/
CONNECTING A Bluetooth®
PHONE
To use the hands-free system for cellular
phones, it is necessary to register a cel-
lular phone with the system. ( →P.31)
