Always make sure that the indicator lamps in the
“SOS” button, in the “Roadside Assistance” button and
in the “Information” button do not remain illuminated
constantly in red and the message “TELE AID – VISIT
WORKSHOP” is not displayed in the multifunction
display after the system self check.
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Center as
soon as possible.
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 43 and 44.
An emergency call can also be initiated manually by
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”

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
multif un ction d isp lay. The Res pon se Cen ter will attemp t

Te ch n i c a l
data Instruments

cluster displayPractical hints Car care Index Supplemental restraint system (SRS) indicator lamp
When turning the electronic key in starter
switch to position 1 the indicator lamp “SRS”
in the instrument cluster comes on. If no
fault is detected, the lamp will go out after
approximately 4 seconds.
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.
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 or 2.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.
See page 67 for notes on airbags, see page 65 for belt
tensioners and page 56 for infant and child seat
restraint.
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.

multifunction display
Malfunction and warning messages for the following
systems will be displayed immediately in the
multifunction display.
They are divided into three categories.
Category C1:
Messages of most immediate priority.
These cannot be cleared from the instrument cluster
using the reset knob on the instrument cluster (see
page 94).
Categories C2 and C3:
Messages of less immediate priority.
These can be cleared from the instrument cluster using
the reset knob on the instrument cluster (see page 94)
and are then stored in the malfunction message
memory. See page 113.
Wa r n i n g !
The BabySmart
TM airbag deactivation system will
ONLY work with a special child seat designed to
operate with it. It will not work with child seats
which are not BabySmart
TM compatible.
Never place anything between seat cushion and
child seat (e.g. pillow), since it reduces the
effectiveness of the deactivation system.Follow the manufacturer’s instructions for
installation of special child seats.The passenger front airbag will not deploy only if
the ü indicator lamp remains illuminated.Please be sure to check the indicator every time
you use the special system child seat. Should the
light go out while the restraint is installed, please
check installation. If the light remains out, do not
use the BabySmart
TM restraint to transport children
on the front passenger seat until the system has
been repaired.
