GMC Sierra Owners Manual
Care of the CD and DVD Player
Do not add any label to a disc.
It could get caught in the CD or DVD player. If a disc is recorded on a personal computer and a description label is needed, try labeling the top of the recorded disc with a marking pen.
The use of CD/DVD lens cleaners is not advised, due to the risk of contaminating the lens of the optics with lubricants internal to the CD and DVD player mechanism.
Notice: If a label is added to a CD, 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.
If an error displays, see “CD Messages” later in this section.
Care of CDs and DVDs
If playing a CD-R or CD-RW, the sound quality can be reduced due to CD-R or CD-RW quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R or CD-RW has been handled. Handle them carefully.
Store CD-Rs or CD-RWs in their original cases or other protective cases and away from direct sunlight and dust. The CD or DVD player scans the bottom surface of the disc. If the surface of a disc is damaged, such as cracked, broken, or scratched, the disc does not play properly or not at all. Do not touch the bottom side of a disc while handling it; this could damage the surface. Pick up discs by grasping the outer edges or the edge of the hole and the outer edge.
If the surface of a disc is soiled, clean it with a soft, lint-free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water. Make sure the wiping process starts from the center to the edge.
Only one audio source can be heard through the speakers at one time.
An audio source is defined as DVD slot, CD slot, XM, FM-AM, front auxiliary jack, USB port, or rear auxiliary jack.
Press the O button to turn the radio on. The radio can be heard through all of the vehicle speakers.
Front seat passengers can listen to the radio (AM, FM, or XM if equipped) by pressing the BAND button or the DVD/CD AUX button to select CD slot, DVD slot, front auxiliary input, USB port, or rear auxiliary input (if available).
If a playback device is plugged into the radio’s front auxiliary input jack, USB port, or the rear auxiliary jack, the front seat passengers are able to listen to playback from this source through the vehicle speakers. See “Using the Auxiliary Input Jack” in Auxiliary Devices on page 7‑33, or “Audio/Video (A/V) Jacks” under Rear Seat Entertainment (RSE) System on page 7‑38 for more information.
In some vehicles, depending on audio options, the rear speakers can be muted when the RSA power is turned on. See Rear Seat Audio (RSA) System on page 7‑48 for more information.
Inserting a Disc
Insert a disc partway into either slot, label side up. The player pulls it in and the disc should begin playing.
(Loading a disc into the system, depending on media type and format, ranges from 5 to 20 seconds for a CD, and up to 30 seconds for a DVD to begin playing.)
Ejecting a Disc
CD (Eject): Press and release to eject the disc that is currently playing. The CD ejects from the bottom slot. A beep sounds and Ejecting Disc displays. Once the disc is ejected, Remove Disc displays. The disc can be removed.
If the disc is not removed, after several seconds the disc automatically pulls back into the player.
DVD (Eject): Press and release to eject the disc that is currently playing in the top slot.
A beep sounds and Ejecting Disc displays.
If loading and reading of a disc cannot be completed, due to unknown format, etc., and the disc fails to eject, press and hold for more than five seconds to force the disc to eject.
