Operation - MCS and telephone
MCS navigation supplies you with information to help
you select your route more easily and guides you conve-
niently and safely to your destination. For safety’s sake,
you should not use some of the functions, such as enter-
ing the destination, unless your vehicle is stationary
(electronic key in the steering lock at position 1).
The navigation system does not supply any informa-
tions on stop signs, yield signs, traffic regulations or
traffic safety rules or changes in roads. This always
remains your personal responsibility.Operation safetyG
Wa r n i n g !
In order to avoid distractions which could lead to
an accident, system settings should be entered with
the vehicle at 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 m.p.h.
(approximately 50 km/h), your car is covering a
distance of 50 feet (approximately 14 m) every sec-
ond.

Wa r n i n g !
Any alterations made to electronic components and
the software can cause malfunctions.
The radio, amplifier, CD changer and telephone are
interconnected. Therefore, when one of the compo-
nents is not operating properly or has not been
repaired , it may impair the function of other com-
ponents.
This condition might seriously impair the operat-
ing safety of your vehicle.
We recommend that you have any service work or
alternations to electronic components done in an
authorized Mercedes-Benz Center. Introduction
