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 )  e v e r y  s e c o n d .
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.
