Audio 50 Operator’s Manual
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
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.
Introduction
Operating safety
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.
