An indicator light on the upper left side of the radio flashes when the ignition is off, to indicate the theft deterrent feature is set. For more information, see Theft-Deterrent Feature .

Your vehicle has seven Bose® amplified speakers. See your dealer/retailer for details.

Radio Data System (RDS)

The audio system has a Radio Data System (RDS). RDS features are available for use only on FM stations that broadcast RDS information.

With RDS, the radio can do the following:

    • Seek to stations broadcasting the selected type of programming
    • Receive announcements concerning local and national emergencies
    • Display messages from radio stations
    • Seek to stations with traffic announcements

This system relies upon receiving specific information from these stations and will only work when the information is available. In rare cases, a radio station may broadcast incorrect information that will cause the radio features to work improperly. If this happens, contact the radio station.

While the radio is tuned to an RDS station, the station name or call letters will appear on the display. RDS stations may also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast.

XM™ Satellite Radio Service

If your vehicle has the XM™ satellite radio service, it is based in the 48 contiguous United States and Canada. XM™ offers a large variety of coast-to-coast channels including music, news, sports, talk, traffic/weather (U.S. subscribers), and children’s programming. XM™ provides digital quality audio and text information that includes song title and artist name. A service fee is required in order to receive the XM™ service. For more information, contact XM™; In the U.S. at www.xmradio.com or call 1-800-852-XMXM (9696) or in Canada at www.xmradio.ca or call 1-877-GET-XMSR (438-9677).

Playing the Radio

Top Knob (Power/Volume): Press this knob to turn the system on and off. Turn this knob to increase or to decrease the volume.

(Information): For RDS, press this button to change what appears on the display while using RDS. The display options are station name, RDS station frequency, PTY, and the name of the program (if available). For XM™ (if equipped), press the information button while in XM™ mode to retrieve four different categories of information related to the current song or channel: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, press the information button until you see the display you want, then hold the button for two seconds. The radio will produce one beep and the selected display will now be the default.

AUTO (Automatic Volume): With automatic volume, the audio system will adjust automatically to make up for road and wind noise as you drive, by increasing the volume as vehicle speed increases. Set the volume at the desired level. Press this button to select AUTO VOLUME MIN, AUTO VOLUME MED, or AUTO VOLUME MAX. Each higher setting will provide more volume compensation at faster vehicle speeds. To turn automatic volume off, press this button until AUTO VOLUME OFF appears on the display. If your vehicle has the Bose® audio system, it includes Bose® AudioPilot® noise compensation technology. When turned on, AudioPilot® continuously adjusts the audio system to compensate for background noise, so that your music always sounds the same at the set volume level. This feature is most effective at lower radio volume settings where background noise can affect how well you hear the music being played through your vehicle's audio system. At higher volume settings, where the music is much louder than the background noise, there may be little or no adjustments by AudioPilot®. To use AudioPilot®, set the radio volume to your desired level. Turn AudioPilot® on by pressing the automatic volume button until AVOL ON displays. As the vehicle goes faster, the background noise increases. AudioPilot® adjusts the audio system's sound level to overcome background noise. To turn AudioPilot® off, press the automatic volume button until AVOL OFF displays. For additional information on AudioPilot®, visit www.bose.com/audiopilot.

Playing a CD (Single CD Player)

Insert a CD partway into the slot, label side up. The player will pull it in and the CD should begin playing.

If the ignition or radio is turned off with a CD in the player, it will stay in the player. When the ignition or radio is turned on, the CD will start playing where it stopped, if it was the last selected audio source.

When a CD is inserted, CD and the CD symbol will appear on the display. As each new track starts to play the track number will appear on the display.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

If playing a CD-R, the sound quality (and playback performance) may be reduced due to the CD-R quality, method of recording, the quality of the music that has been recorded, and the way the CD-R has been handled. For better playback performance when home burning audio discs, use brand named CD media with the ["Compact Disc" trade mark logo], and a burn rate no faster than 12X.

There may be an increase in skipping, difficulty in finding tracks, and/or difficulty in loading and ejecting. If these problems occur, check the bottom surface of the CD. If the surface of the CD is damaged, such as cracked, broken, or scratched, the CD will not play properly. If the surface of the CD is soiled, see Care of Your CDs for more information.

If there is no apparent damage, try a known good CD.

Do not add any label to a CD, it could get caught in the CD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen instead.

Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris.
