Operating safety
WarningG
Any alterations made to electronic compo-
nents and the software can cause malfunc-
tions.
The radio, amplifier, CD changer*, satellite
radio*, telephone* and navigation module
are interconnected. When one of the com-
ponents is not operational or has not been
removed/replaced properly, the function of
other components may be impaired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
only by qualified personnel.
WarningG
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a stand-
still and operate the system only when road,
weather and traffic conditions permit.
Bear in mind that at a speed of just
30 mp/h (approximately 50 km/h), your car
is covering a distance of 44 feet (approxima-
tely 14 m) every second.
COMAND supplies you with information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we encoura-
ge the driver to stop the vehicle in a safe
place before answering or placing a call, or
consulting the COMAND screen to read na-
vigational maps, instructions, or downloa-
ded information.
While the navigation system provides direc-
tional assistance, the driver must remain fo-
cused on safe driving behavior, including
attention to traffic and street signs, and
should utilize the system’s audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. This al-
ways remains your personal responsibility
when you drive. DVD maps do not cover all
areas nor all routes within an area.

General information on CD operation
WarningG
In order to avoid distraction which could
lead to an accident, the driver should insert
CDs with the vehicle at a standstill and
operate the audio system only if permitted
by road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car covers a
distance of 44 feet (approximately 14 m)
every second.
Health hazardG
The CD drive and CD changer* are Class 1
laser products. There is a danger of invisible
laser radiation when you open or damage
the cover.
Do not remove the cover. The CD drive and
the CD changer* do not contain any parts
which can be serviced by the user. For safe-
ty reasons, have any necessary service work
performed by qualified personnel.
i
Only use CDs, which bear the label
shown and that conform to the compact
standard (IEC 60908). You can there-
fore only use CDs with a maximum
thickness of 1.3 mm.
i
The system may not be able to
play CDs with copy protection or
copied CDs.
!
Use only CDs with a diameter of 12 cm,
do not use 8-cm CDs.
An 8-cm CD adapter may cause dama-
ge to the CD drive and to the CD chan-
ger* and should not be used.
i
Your CD drive has been designed to
play CDs which correspond to the IEC
60908 standard.
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.
