Your COMAND equipment
These operating instructions describe all
standard and optional equipment available
for your COMAND system at the time of
purchase. Country-specific differences are
possible. Please note that your
COMAND system may not be equipped with
all the features described. This also applies to

WARNING
If you operate mobile communication
equipment 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.
If you make a call on your mobile phone while
driving, always use hands-free mode. Only
use the mobile phone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile phone while driving a vehicle.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m)
per second.
Excessive levels of electromagnetic radiation
may cause damage to your health and the
health of others.
There is scientific discussion surrounding the
possible health risks posed by
electromagnetic fields. You can reduce this
risk by using an exterior antenna. Therefore, only use mobile communication
equipment if it is connected to the exterior
antenna of the vehicle. Introduction
