WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and oper-
ate the audio system only when road, weath-
er and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
!
Do not attach labels of any type to the
CD. They may become detached and
damage the drive.
Your CD drive has been designed to
play CDs which correspond to the IEC
60908 standard. Therefore only CDs
not exceeding a thickness of 1.3 mm
can be used.
!
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 will become stuck and
damage the drive.
Data carriers which contain data on
both sides can cause play-back prob-
lems because the storage layers are
thinner than one-sided data carriers.
Do not play single-CDs (80 mm) with an
adapter. An adapter could become
stuck and damage the drive. Only use
12 cm diameter CDs.
i
The COMAND CD drive may not be able
to play audio CDs with copy protection.
