Control and operation of radio transmitters
COMAND, radio and telephone
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the COMAND (Cockpit Management and Data
System), radio or telephone
1 if road and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m) every second.
Wa r n i n g !
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.
