not even with a CD adapter. Attempting to 
play CDs with an eight cm diameter or 
playing such CDs with an adapter may 
cause damage to the CD drive. Such 
damage is not covered by the 
Mercedes-Benz Limited Warranty. 
Should excessively high or low tempera-
tures occur while in CD changer mode*, CD TEMP
 will appear in the display, and the 
CD will be muted until the temperature has

The single CD player and the CD changer* 
play audio CDs.Tips on handling CDs
Handle CDs carefully to prevent 
interference during playback.
Avoid scratches, fingerprints and dust 
on the CDs.
Do not write on CDs or apply any labels 
or other material to them.
Clean CDs from time to time with a 
commercially available cleaning cloth. 
Never wipe the CD in a circular motion; 
instead, wipe it in a straight line start-
ing in the center and moving outward. 
Do not use solvents, anti-static sprays, 
etc. for cleaning.
Replace the CD in its case after use.
Protect CDs from heat and direct 
sunlight.
!If you affix stickers to the CDs, they can 
become warped due to the heat that 
develops in the CD drive or 
CD changer.
In certain situations, the CDs can then 
no longer be ejected and cause 
damage to the drive. Such damage is 
not covered by the Mercedes-Benz 
Limited Warranty.!Your CD drive or CD changer has been 
designed to play CDs which 
correspond to the EN 60908 standard. 
You can therefore only use CDs with a 
maximum thickness of 1.3 mm.
If you insert thicker data carriers, e.g. 
ones that have data on both sides (one 
side with DVD data, the other side with 
audio data), they cannot be ejected and 
will damage the drive.
