Flexible service system (FSS) 
(service indicator)
The FSS permits a flexible service schedule that is 
directly related to the operating conditions of the 
vehicle.
The symbol 9 or š appears in the main odometer 
display field prior to the next suggested service.
Depending on operating conditions throughout the year, 
the next service is calculated and displayed in days 
š or distance 9 remaining.The symbols 9 or ´ indicate the type of service 
to be performed:
9Service A
´Service B
The message is displayed for approximately 10 seconds 
when turning the key in steering lock to position 2, or 
while driving when reaching the service warning 
threshold. It can be canceled manually by pressing 
button (1).
Once the suggested term has passed, the message plus 
symbol 9 or š, preceded by a – (minus symbol) 
blinks for approx. 30 seconds and a signal sounds every 
time when turning the key in steering lock to position 2.
The FSS display can also be called up for approx. 
10 seconds with display illuminated by pressing 
button (1) twice within 1 second.
Following a completed A or B service the Mercedes-Benz 
Center sets the counter to 10 000 miles (Canada: 15 000 
km) and 365 days.

157 Tele Aid
Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Emergency calls
An emergency call is initiated automatically:
• following an accident in which the Emergency 
Tensioning Retractors (ETR’s) or airbags deploy,
• if the antitheft alarm or the tow away alarm stays on 
for more than 20 seconds, see page 42 and page 43.
An emergency call can also be initiated manually by 
opening the cover next to the interior rear view mirror 
labeled “SOS”, then pressing the button (for longer than 
2 seconds) located under the cover. See below for 
instructions on initiating an emergency call manually.
Once the emergency call is in progress, the indicator 
lamp in the “SOS” button will begin to f lash. All 
information relevant to the emergency, such as the 
location of the vehicle (determined by the GPS satellite 
location 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 after the emergency call has been 
initiated. When a voice connection is established the 
audio system mutes. The Response Center will attempt 
to determine more precisely the nature of the accident 
provided they can speak to an occupant of the vehicle.The Tele Aid system is available if:
• it has been activated and is operational. Activation 
requires a subscription for monitoring services and 
cellular air time
• the relevant cellular phone network and GPS signals 
are available pass the information on to the 
Response Center.
Note:
Location of the vehicle on a map is possible if the 
vehicle is able to receive signals from the GPS satellite 
network pass the information on to the Response 
Center.
Wa r n i n g !
If the indicator lamp in the “SOS” button is 
illuminated continuously and there was no voice 
connection to the Response Center established, 
then the Tele Aid system could not initiate an 
emergency call (e.g. the relevant cellular phone 
network is not available).Should this occur, assistance must be summoned 
by  oth er means.

Notes:
The indicator lamp in the Roadside Assistance 
button• remains illuminated in red for approx. 
10 seconds during the system self-check after turning 
key in steering lock to position 2 (together with the 
“SOS” button and the Information button¡).
See system self-check on page 156 when the indicator 
lamp does not light up in red or stays on longer than 
approximately 10 seconds.
If the indicator lamp in the Roadside Assistance 
button• is illuminated continuously and there was 
no voice connection to the Response Center established, 
then the Tele Aid system could not initiate an Roadside 
Assistance call (e.g. the relevant cellular phone network 
is not available).
Information button ¡
Located below the center armrest cover is the 
Information button¡. Pressing and holding the 
button (for longer than 2 seconds), will initiate a call to 
the Client Assistance Center. The button will flash while 
the call is in progress.The Tele Aid system will transmit data generating the 
vehicle identification number, model, color and location 
(subject to availability of cellular and GPS signals).
A voice connection between the Client Assistance 
Center representative and the occupants of the vehicle 
will be established. When a voice connection is 
established the audio system mutes. Information 
regarding the operation of your vehicle, the nearest 
Mercedes-Benz Center or Mercedes-Benz USA  products 
and services is available to you.

Important!
If the indicator lamps do not start flashing 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 active, and may not 
initiate a call. Visit your Mercedes-Benz Center and 
have the system checked or contact the Response Center 
at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in 
Canada) as soon as possible.Upgrade Signals
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 (alternating) tone will be heard, 
and the appropriate indicator lamp will flash. If certain 
information such as vehicle identification number or 
client information is not available, the operator may 
need to retransmit. During this time you will hear a 
chirp and voice contact will be interrupted. Voice 
contact will resume once the retransmission is 
completed. Once a call is concluded, a chirp will be 
heard and the appropriate indicator lamp will stop 
flashing. The audio system operation will resume.
