Mercedes-Benz
Congratulations on your new
Mercedes-Benz car radio.
Please familiarise yourself with your car radio and read the operating manual before
driving off. This will ensure your complete
enjoyment of your car radio and prevent
danger to yourself and to others.
Depending on the equipment version and
your vehicle model, the following components may be installed: CD changer*, telephone*, LINGUATRONIC* and sound
system*.
The operating manual also contains descriptions of these functions. Therefore, it
is possible that some of the descriptions
contained herein do not apply to your
radio.
Mercedes-Benz constantly update their car
radios to the latest technological standards and therefore retain the right to implement changes in design, equipment and
technology. Thus, no liability can be derived from the statements, illustrations
and descriptions contained in this operating manual.
For further questions, please contact your
Mercedes-Benz service centre.
This operating manual is a component part
of your vehicle. It should therefore always
be kept in your vehicle and should be
passed on to the new owner, if the car is
sold.
The Technical Editors of
DaimlerChrysler AG wish
you “Good driving”.

Operating safety
Introduction
Operating safety
Accident hazard G
In order to avoid distraction which could
lead to an accident, system settings should
be entered with the vehicle at a standstill
and the system should be operated by the
driver only when traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is covering a distance of 50 feet (approximately
14 m) every second.
iFaults
The Audio 50, the CD-changer*, the
telephone*, the LINGUATRONIC* and
the Sound-system* are interconnected. Thus, the failure or incorrect removal of one of the components can also
interfere with the function of the
others.
For this reason, work on the components should be performed by a specialist workshop.
iServicing
Always have all servicing carried out by
a qualified specialist workshop.
DaimlerChrysler recommends your
Mercedes-Benz Service center, as this
has the necessary expertise and tools
for any necessary operations.
In particular for operations critical to
safety and operations on systems critical to safety, servicing by a qualified
specialist workshop is essential.
