COMAND is classified as a Class 1 laser
product. You must not open the casing. There
is a risk of exposure to invisible laser radiation
if you open the casing, or if the casing is faulty
or damaged.
COMAND does not contain any parts that you
are able to maintain yourself. For safety
reasons, all maintenance work must be
exclusively carried out by qualified
technicians.

There is a risk of accident by being distracted

Vehicle Equipment
i This Operator's manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual.
Automatic Picture Switch-off
If the vehicle is traveling faster than
approximately 3 MPH, the picture will switch
off automatically in DVD video mode.
The following message appears in the display:
In order not to distract you from the
traffic situation, the picture is
faded out while the vehicle is in
motion.
As soon as the vehicle speed drops below
approximately 3 MPH, the picture switches
back on again.
Notes on Storage Media
i When playing copied discs, problems may
occur with the playback. A wide variety of
disc-writing software and writers are
available. Due to this variety we cannot
guarantee that the system will be able to
play discs that you have written/copied
yourself.
! Do not affix stickers or labels to the discs,
as they could peel off and damage
COMAND. Stickers can cause the disc to
bend, which can result in read errors and
disc recognition problems.
! COMAND is designed to hold discs which
comply with the EN 60908 standard. You
can therefore only use discs with a
maximum thickness of 1.3 mm.
If you insert thicker discs, e.g. those that
contain data on both sides (DVD on one
side and audio data on the other), they
cannot be ejected and can damage
COMAND.
Do not use discs with a diameter of 8 cm,
even with an adapter. Only use round discs
with a diameter of 12 cm.
Notes on the Care of Discs
Only hold discs by the edge.
R
Handle discs with care in order to prevent
R
malfunctions during playback.
Avoid scratching, leaving fingerprints and
R
dust on the discs.
Clean the discs occasionally with a
R
commercially available cleaning cloth.
Always wipe in a straight line from the
inside outwards, never in a circular motion.
