Important safety notes
GWARNING
If you operate mobile communication equip-
ment while driving, you will be distracted from traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate this equipment when the vehicle
is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating mobile communication equipment.
Please remember, a navigation system does not
supply information on the load-bearing capacity of bridges or the overhead clearance of under-
passes. The driver remains responsible for
safety at all times.
You and others can suffer health-related dam-
age through electromagnetic radiation. By using
an exterior antenna, a possible health risk
caused by electromagnetic fields, as discussed
in scientific circles, is taken into account. Only
have the exterior antenna installed by a qualified
specialist workshop.
You will find information on installing electrical
or electronic equipment in the “Vehicle elec-
tronics” section (
Ypage 271).
