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 Center for informa-
tion on the installation of an approved 
external antenna. Refer to the radio trans-
mitter operation instructions regarding use 
of an external antenna.
You can take and place telephone calls 
using the
í and ì buttons on the 
steering wheel. To carry out other tele-
phone functions, use the control system 
(
page 138).
See separate operating manual for instruc-
tions on how to use 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 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, 
weather and traffic conditions permit. Some 
jurisdictions prohibit the driver from using a 
cellular telephone while driving a vehicle.
Only operate the COMAND* (Cockpit Man-
agement and Data System)
1
 if road, weather 
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 approx. 44 feet 
(approximately 13.5 m) every second.

Some jurisdictions prohibit the driver from

vehicle. Whether or not prohibited by law, 
for safety reasons, the driver should not use 
the cellular telephone while the vehicle is in 
motion.
Stop the vehicle in a safe location before 
answering or placing a call.
