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 and
traffic conditions permit. Some jurisdictions
prohibit the driver from using a cellular tele-
phone while driving a vehicle.
Only operate the COMAND* (Cockpit Man-
agement and Data System)
1 if road and traf-
fic conditions permit.
1Observe all legal requirements.
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 (ap-
proximately 13.5 m) every second.Warning!

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 before an-
swering or placing a call.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and

tivated
will be shown in the multifunc-

Upgrade signals
The Tele Aid system processes calls using
the following priority:
Automatic emergency – First priority
Manual emergency – Second priority
Roadside assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard, and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard and the
appropriate indicator lamp will stop flash-
ing. The COMAND* system operation will
resume. See system self-check (
page 235)
when the indicator lamp does not light
up in red or stays on longer than ap-
proximately 10 seconds.
If the indicator lamp in the Information
button¡ is illuminated continuous-
ly and there was no voice connection to
the Response Center established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
INFO –
CALL FAILED
appears in the multifunc-
tion display.
Information calls can be terminated us-
ing the ìbutton on the multifunc-
tion steering wheel.
!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
fault or the service is not currently ac-
tive, and may not initiate a call. Visit
your authorized Mercedes-Benz Center
and have the system checked or con-
tact the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
