Operating safety
Warning!
G
In order to avoid distraction which could
lead to an accident, the driver should enter
system settings with the vehicle at a
standstill 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
covering a distance of 44 feet
(approximately 14 m) every second.
Warning!
G
Any alterations made to electronic
components can cause malfunctions.
The radio, amplifier, CD changer*, satellite
radio* and telephone* are interconnected.
When one of the components is not opera-
tional 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
by an authorized Mercedes-Benz Center.
