Cellular telephone
The vehicle is prepared for the installation of a cellular 
telephone. For further information and installation 
contact your authorized Mercedes-Benz Center.
Wa r n i n g !
A driver’s attention to the road must always be his/
her primary focus when driving. For your safety 
and the safety of others, we recommend that you 
pull over to a safe location and stop before placing 
or taking a telephone call. If you choose to use the 
telephone while driving, please use the hands-free 
device and only use the telephone when road and 
traffic conditions permit.Some jurisdictions prohibit the driver from using a 
cellular telephone while driving a vehicle.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. 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.

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.
