Useful features
System self-check
Initially, after switching on the ignition,
malfunctions 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 – Drive to workshop
appears for approximately 10 seconds in
the multifunction display.Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or airbags have deployed.
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.
For more information, see “Initiating an
emergency call manually” (
page 211).
iWhen a Tele Aid call has been initiated,
the audio system is muted and the se-
lected mode (radio or CD) pauses. The
cellular phone (if installed) switches
off. If you must use this phone, we rec-
ommend that you use it only with the
vehicle at a standstill in a safe location.
Remove the phone from the cradle and
place the call. The multifunction display
in the instrument cluster is available for
use. After the Tele Aid call has ended,
the optional cellular phone switches on
again. A PIN entry might be necessary.
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 dur-
ing the system self-check, or if any of these
indicators remain illuminated continuously
in red and/or the message
Tele Aid -
Drive to workshop
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.

What to do if ...
Vehicle status messages in the multifunction display
Warning and malfunction messages
appear in the multifunction display located
in the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 124) displays both cleared and
uncleared messages.
High-priority messages appear in the
multifunction display in red color.
Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 29). Other messages of high priority and
messages of less immediate priority can
be cleared from the multifunction display
using the reset button. They are then
stored in the vehicle status message mem-
ory (
page 124). Remember that clearing
a message will only make the message dis-
appear. Clearing a message will not cor-
rect the condition that caused the
message to appear.
Warning!
G
All categories of messages contain
important information which should be
taken note of and, where a malfunction is
indicated, addressed as soon as possible at
an authorized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property
damage or personal injury.
Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
Contact your nearest authorized
Mercedes-Benz Center.iSwitching on the ignition causes all in-
strument cluster lamps (except high
beam headlamp indicator lamp and
turn signal indicator lamps unless acti-
vated) as well as the multifunction dis-
play to come on. Make sure the lamps
and multifunction display are in work-
ing order before starting your journey.
