cluster displayPractical hints Car care Index The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the electronic key in starter switch
to position 1. When turning the electronic key in starter
switch to position 2 the indicator lamp “SRS” in the
instrument cluster comes on. If no fault is detected, the
lamp will go out when the engine is running. After the
lamp goes out, the system continues to monitor the
components and circuitry of the airbag system and will
indicate a malfunction by coming on again. If the lamp
does not come on at all or if it fails to extinguish or if it
comes on thereafter, a malfunction in the system has
been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Have the system checked at your authorized
Mercedes-Benz Center immediately.
In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.Note:
See page 285 for information on the supplemental
restraint system (SRS) indicator lamp.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.

The driver and passenger front airbags are designed to
activate only in certain frontal impacts exceeding a
preset threshold. The front passenger airbag deploys
only if the front passenger seat is occupied and the
ü indicator lamp in the center console is not
illuminated.Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.

Outside temperature indicator (14)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).Adaption to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Note:
The unit for the temperature indicator display can be set
in the individual setting menu “INSTRUMENT
CLUSTER” – “TEMP. INDICATOR” on page 121.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

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”
