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 ½ appears together with a
message in the multifunction indicator prior to the next
suggested service.Depending on operating conditions throughout the year,
the next service is calculated and displayed in days or
distance remaining.
The message is displayed for approximately 10 seconds
when turning the electronic key in starter switch to
position 2, or while driving when reaching the service
warning threshold.
The symbols and messages indicate the type of service
to be performed:
9Service A
½Service B
One of the following messages will appear in the display
(e.g. Service A):
“SERVICE A – IN xx DAYS”
“SERVICE A – IN xx MILES” (Canada: KM)
“SERVICE A – EXCEEDED BY xx DAYS”
“SERVICE A – EXCEEDED BY xx MILES” (Canada: KM)
“SERVICE A – DUE NOW”

in miles, depending on your driving style.
Once the suggested service term has passed, the symbol
and message appear for approximately 30 seconds and
a signal sounds every time when turning the electronic
key in starter switch to position 2.
The service indicator disappears automatically after
30 seconds or if the knob for instrument cluster
illumination, see page 96, in the instrument cluster is
pressed.
Calling up service indicator manually:
Turn the electronic key in starter switch to position 1
or 2.
Call up the trip odometer and main odometer by
pressing button è or ÿ on the multifunction
steering wheel until the display appears. See page 106.
Press button j or k until the FSS indicator
appears.
The next or previous system is displayed by pressing
button è or ÿ.Important!
The FSS indicator is not an engine oil level indicator.
See page 141 for engine oil level indicator.
Note:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

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 pages 44 and 46.

opening the cover next to the inside rear view mirror
labeled “SOS”, then briefly pressing the button 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 flash. The
message “EMERGENCY CALL – CONNECTING CALL”
appears in the multifunction display. When the
connection is established, the message “EMERGENCY
CALL – CALL CONNECTED” appears in the
multifunction display. 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 and the message “TELE AID –
EMERGENCY CALL ACTIVE” appears in the
multifunction display. The Response Center will attempt
to determine more precisely the nature of the accident
provided they can speak to an occupant of the vehicle.

network and 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). The message
“EMERGENCY CALL – CALL FAILED” appears in
the multifunction display for approx. 10 seconds.Should this occur, assistance must be summoned
by other means.
