Operating safety
Location of the audio system
The audio system control panel is located
behind a cover in the upper part of the cen-
ter console.

Warning!
G
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
and traffic conditions permit. Always pay full
attention to traffic conditions first before
operating system controls while driving.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car is cover-
ing a distance of 44 feet (approximately
14 m) every second.
Warning!
G
Any alterations made to electronic compo-
nents can cause malfunctions.
The radio, amplifier, CD changer and
telephone are interconnected. When one of
the components is not operational or has
not been removed/replaced properly, the
function of other components may be im-
paired.
This condition might seriously impair the
operating safety of your vehicle.
We recommend that you have any service
work on electronic components carried out
by an authorized Mercedes-Benz Center.
