WARNING Risk of accident from operating
mobile communication equipment while
the vehicle is in motion
Mobile communication devices distract the
driver from the traffic situation. This can also
cause the driver to lose control of the vehicle.
#
As a driver, only operate mobile commu-
nication devices when the vehicle is sta-
tionary.
#
As a vehicle occupant, use mobile com-
munication devices only in the designa-
ted area, e.g. in the rear passenger com-
partment.
You must observe the legal requirements for the
country in which you are currently driving when
operating the multimedia system and mobile com-
munication equipment in the vehicle.
