Important notes
Important notes
In this chapter you will find detailed infor-
mation on telephone functions, emergency
call, and service numbers.
1 Observe all legal requirements.
Please read the “Telephone” chapter
before attempting to operate your tele-
phone.
Always drive with extreme caution
when you operate the hands-free tele-
phone.
For safety reasons, you should not use
the mobile telephone handset to make
a call while driving the vehicle.
If the signal strength is very weak (dis-
play in the symbol field of all menus),
wait until reception improves before
making a call.
WarningG
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle. Whether or not prohibited by law, for
safety reasons, the driver should not use the
cellular telephone while the vehicle is in mo-
tion. Stop the vehicle in a safe location be-
fore answering or placing a call.
If you nonetheless choose to use the cellular
phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the cel-
lular phone
1 only when road, weather and
traffic conditions permit.
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 malfunction
of the vehicle’s electronic systems, possibly
resulting in an accident and/or personal in-
jury.

Radio transmitters, such as a portable
telephone or a citizens band unit,
should be used inside the vehicle only
if they are connected to a separate ex-
terior antenna that has been approved
by Mercedes-Benz.
