pages. Otherwise the windows could fog up, 
impairing visibility and endangering you and 
others.
iIf the vehicle interior is hot, ventilate the in-
terior before driving off. The climate control will 
then adjust the interior temperature to the set 
value much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
When the retractable hardtop is closed, do not 
obstruct air flow by placing objects on the air 
flow-through exhaust slots below the rear 
window.

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.MP3
The CD changer* can play audio CDs as 
well as CDs with MP3 files.
Information on MP3 data carriersCompatible MP3 data carriers
The CD changer can read the following 
data carriers in MP3 mode:
CD-DA
CD-R
CD-RW
Compatible file systems and compres-
sion methods
Use Romeo or Joliet. Depending on file 
format used, up to 128 characters are 
possible.
The following compression methods are 
compatible:
MP3
WMA
WAV
iCD media, CD burning software and CD 
writers are available in great variety. Due to 
this variety, it cannot be guaranteed that the 
CD changer will be able to play every 
user-written CD.
The burning process can lead to data errors and 
aging of the medium may result in data loss. 
Therefore, the CD changer may be restricted in 
its ability to play MP3 data carriers; it may play 
them with reduced sound quality, or it may not 
be able to play them at all.
Problems may be encountered during playback 
of user-written CDs with a storage capacity of 
more than 700 MB. These CDs do not meet valid 
standards as of this printing.
