Telephone*
Radio transmitters, such as a portable tele-
phone or a citizens band unit, should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
The external antenna must be approved by 
Mercedes-Benz. Please contact an autho-
rized Mercedes-Benz Light Truck Center 
for information on the installation of an ap-
proved external antenna. Refer to the radio 
transmitter operation instructions regard-
ing use of an external antenna.You can take and place telephone calls 
using thes andt buttons on the 
multifunction steering wheel. Use the con-
trol system for performing other telephone 
functions (
page 145).
See separate instruction manual for infor-
mation on how to operate the telephone.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or 
personal injury.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. 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 rec-
ommend that you pull over to a safe location 
and stop before placing or taking a tele-
phone call.
If you choose to use the telephone
1 while 
driving, please use the hands-free device 
and only use the telephone when road, traf-
fic and weather conditions permit. Some ju-
risdictions prohibit the driver from using a 
cellular telephone while driving a vehicle.
Only operate the COMAND (Cockpit 
Management and Data System)
1 if road, 
traffic and weather conditions permit.
Bear in mind that at a speed of just 30 mph 
(approximately 50 km / h), your vehicle is 
covering a distance of 44 feet 
(approximately 14 m) every second.
