Precautions for use of discs CAUTION: Do not look directly at the laser pickup because the CD player uses an invisible laser beam. Be sure to operate the player only as instructed. NOTE:  Do not disassemble any part of the CD player.  Do not apply oil to the CD player.  Do not insert anything but a CD into the CD player. NOTE:  Copy-protected CDs cannot be played.  CD-Rs and CD-RWs may not be played depending on the recording conditions or characteristics of the discs, or due to damage, dirt, or deterioration caused by leaving the discs in the cabin for a long time.  Unfinalized CD-Rs and CD-RWs cannot be played.  Keep the discs away from dirt. Be careful not to damage the discs or leave your fingerprints on them.  Hold discs by the outer edge and center hole with the label side up.  Leaving the disc exposed halfway out of the slot for a long time after pressing the disc eject button may cause deformation of the disc, making the disc unusable.  If discs have adhesive tape, stickers, CD-R labels, or any traces of such labels attached, the discs may not be ejected or player malfunctions may result.  Keep the discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.)  Do not use odd-shaped CDs because these may cause player malfunctions. 2009 Toyota Highlander Limited 2009 ACCESSORIES & EQUIPMENT Audio/Visual - Highlander

HINT:  When it is cold or it is raining, if the windows mist up, mist and condensation may form in the player. In such cases, the CD may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.  The CD may skip if the player experiences strong vibrations when the vehicle is driven on rough road or similar uneven surface(s). d. Cleaning 1. If dirt is on the disc surface, wipe it clean with a soft dry cloth such as an eyeglass cleaner for plastic lenses from the inside to the outside in a radial direction.

For this reason, some CD-Rs and CD-RWs do not play.  If there are fingerprints or scratches on the disc, the disc may not play or the CD may skip.  Some CD-Rs and CD-RWs may deteriorate if they are left in the cabin for a long time.  Keep CD-Rs and CD-RWs in an opaque case. 2009 Toyota Highlander Limited 2009 ACCESSORIES & EQUIPMENT Audio/Visual - Highlander

MEDIA FORMAT REFERENCE CHART HINT:  As for MP3/WMA files written in any listed format, the contents of the files may not play normally or the file names or folder names may not display correctly.  This player is compatible with multi-session discs and can play CD-Rs and CD-RWs on which MP3/WMA files are added. However, only the first session can be played.  Discs whose first session includes both music data and MP3 or WMA format data cannot be played. 2. Standard and restrictions STANDARD AND RESTRICTIONS REFERENCE CHART f. File names 1. Only files with an extension of ".mp3" or ".wma" can be recognized and played as MP3 or WMA files. 2. Save MP3 or WMA files with an extension of ".mp3" or ".wma". 3. AVC-LAN DESCRIPTION a. What is AVC-LAN?

A loud noise may occur and damage to the speaker may result. 2009 Toyota Highlander Limited 2009 ACCESSORIES & EQUIPMENT Audio/Visual - Highlander

Courtesy of TOYOTA MOTOR SALES, U.S.A., INC. AVC-LAN, an abbreviation for "Audio Visual Communication Local Area Network", is a united standard developed by the manufacturers in affiliation with Toyota Motor Corporation. This standard pertains to audio and visual signals as well as switch and communication signals. b. Purpose: Recently, car audio systems have rapidly developed and the functions have vastly changed. The conventional car audio system is being integrated with multi-media interfaces similar to those in navigation systems. At the same time, customers are demanding higher quality from their audio systems. This is merely an overview of the standardization background. The specific purposes are as follows: 1. To solve sound problems, etc. caused by using components of different manufacturers through signal standardization. 2. To allow each manufacturer to concentrate on developing products they do best. From this, reasonably priced products can be produced. HINT:  If a short to +B or short to ground is detected in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning.  If the audio system has a navigation system installed, the multi-display unit acts as the master unit. If the navigation system is not installed, the audio head unit acts as the master unit instead. If the radio and navigation assembly is installed, it is the master unit.  The radio receiver contains a resistor that is necessary to enable communication on the different AVC-LAN circuits.  The car audio system with an AVC-LAN circuit has a diagnostic function.  Each component has a specified number (3-digit) called a physical address. Each function has a number (2-digit) called a logical address. 4. COMMUNICATION SYSTEM OUTLINE a. Components of the audio system communicate with each other via the AVC-LAN. b. The master component of the AVC-LAN is a radio receiver with a 60 to 80 ohms resistor. This is essential for communication. c. If a short circuit or open circuit occurs in the AVC-LAN circuit, communication is interrupted and the audio system will stop functioning. 5. DIAGNOSTIC FUNCTION OUTLINE a. The audio system has a diagnostic function (the result is indicated on the master unit). b. A 3-digit hexadecimal component code (physical address) is allocated to each component on the AVC-LAN. Using this code, the component in the diagnostic function can be displayed. 6. "BLUETOOTH" OUTLINE a. "Bluetooth" is a trademark owned by Bluetooth SIG. Inc. b. "Bluetooth" is a new wireless connection technology that uses the 2.4 GHz frequency band. This 2009 Toyota Highlander Limited 2009 ACCESSORIES & EQUIPMENT Audio/Visual - Highlander

makes it possible to connect a cellular phone ("Bluetooth" compatible phone *1 ) to the radio receiver (the "Bluetooth" system is built in), and use the handsfree function of the cellular phone, even if it is in a pocket or bag. As a result, it is not necessary to use a connector attached directly to the cellular phone. *1 : Some versions of "Bluetooth" compatible cellular phones may not function. Fig. 7: Identifying Bluetooth Radio Wave Courtesy of TOYOTA MOTOR SALES, U.S.A., INC. HINT: The communication performance of "Bluetooth" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity, or antenna capacity. 7. ASL (Automatic Sound Levelizer) FUNCTION OUTLINE a. The ASL (Automatic Sound Levelizer) function automatically adjusts the sound data in order to enable to hear the clear audio sound even when vehicle noise increases (as vehicle noise increases, the volume is turned up etc.). Vehicle speed signals are received from the combination meter and used for the ASL (Automatic Sound Levelizer). HOW TO PROCEED WITH TROUBLESHOOTING 1. VEHICLE BROUGHT TO WORKSHOP 2.
