during vehicle operation. The driver is and
must always remain responsible for the
vehicle’s speed and for safe braking
operation.
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal

To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.System self-check
Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button•, and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message
Tele Aid Inoperative appears
for approximately 10 seconds in the multi-
function display.
iThe SOS button is located in the overhead
control panel.
The Roadside Assistance button•
(
page 266) and the Information button¡
(
page 267) are located in the center armrest
storage/telephone* compartment.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (Global
Positioning System) satellites for vehicle loca-
tion. If either of these signals are unavailable,
the Tele Aid system may not function and if this
occurs, assistance must be summoned by other
means.
iWhen a Tele Aid call has been initiated, the
audio system or COMAND* system audio is mut-
ed and the selected mode (radio, tape or CD)
pauses. The optional cellular phone* (if installed)
and inserted in cradle switches off. If you must
use this phone, we recommend that you use it
only with the vehicle at a standstill in a safe loca-
tion. Remove the phone from the cradle and
place the call. The COMAND* navigation system
(if engaged) will continue to run. The display in
the instrument cluster is available for use, and
spoken commands are only available by pressing
the RPT button on the COMAND* unit. A pop-up
window will appear in the COMAND* display to
indicate that a Tele Aid call is in progress. After
the Tele Aid call has ended, the optional cellular
phone switches on again. A PIN entry might be
necessary.

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 265) for instruc-
tions on initiating an emergency call man-
ually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting Call
appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
Call Connected appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion system), vehicle model, identification
number and color are generated.A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:
it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time.
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center.
Warning!G
If the indicator lamps in the SOS button, in
the Roadside Assistance button, and/or in
the Information button do not come on
during the system self-check or if any of
these indicators remain illuminated
constantly in red and/or the message
Tele Aid Inoperative is displayed in the
multifunction display after the system
self-check, a malfunction in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only
possible if the vehicle is able to receive signals
from the GPS satellite network and pass the
information on to the Response Center.
