Roadside Assistance and
information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç or use the volume knob
on your COMAND headunit.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.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
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using
button¡. Failure to complete either
of these steps will result in a system
that is not activated.
If you have any questions regarding ac-
tivation, please call the Response Cen-

these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-

362 OperationMaintenanceCalling up the maintenance service indicator display
You can call up the maintenance service
indicator display at any time to check
when the next maintenance service is due.
Switch on the ignition (
page 36).
Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display appears in
the multifunction display (
page 153).
Press button k or j until the
maintenance service indicator display
with the service symbol 9 and the
service deadline appears in the multi-
function display.Resetting the maintenance service
indicator
In the event that the maintenance service
on your vehicle is not carried out by an au-
thorized Mercedes-Benz Center, you can
have the maintenance service indicator re-
set. The automotive maintenance facility
carrying out the maintenance service will
find the information for resetting the main-
tenance service indicator in the mainte-
nance-relevant information for your
vehicle. Such information is available from
either your authorized Mercedes-Benz
Center or directly from Mercedes-Benz.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.

374 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP
® are also
switched off (see messages in the multifunc-
tion display).
The electrohydraulic brake system is still
functioning normally but without the ABS
available.
If the ABS control unit is malfunctioning, oth-
er systems such as the Parktronic system*,
Distronic*, or the automatic transmission
may also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 386).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be sufficiently charged.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
