Important!
The initial activation of the Tele Aid system may only be
performed by completing the subscriber agreement and
placing an acquaintance call using the “SOS” button.
Failure to complete either of these steps will result in a
system that is not activated.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
(Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.
The Tele Aid system is always operational, providing
that the vehicle’s battery is charged and properly
connected. To activate, press the “SOS” button, the
Roadside Assistance button or the Information
button¡, depending on the type of response
required.System self-check
Initially, after turning the key in steering lock to
position 2, malfunctions are detected and indicated (the
indicator lamps in the “SOS” button, the Roadside
Assistance button and the Information
button¡ stay on longer than 5 seconds or do not
come on).
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Center as
soon as possible.
Important!
Always make sure that the indicator lamp in the
“SOS” button remains illuminated for approx. 5 seconds
during the system self-check after turning key in
steering lock to position 2.
Emergency calls
An emergency call is initiated automatically following
an accident in which the Emergency Tensioning
Retractors (ETR’s) or airbags deploy. An emergency call
can also be initiated manually by opening the cover next
to the interior rear view mirror labeled “SOS”, then

156 Tele Aid
Technical
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index
pressing the button (for longer than 2 seconds) 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. 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. The Response Center will attempt to determine
more precisely the nature of the accident provided they
can speak to an occupant of the vehicle.
The Tele Aid system is available if:
• it has been activated and is operational. Activation
requires a subscription for monitoring services and
cellular air time,
• t h e r e l ev a n t c e l l u l a r p h on e n e t w or k a n d G P S si g n a l s
are available.Note:
Location of the vehicle on a map is possible if the
vehicle is able to receive signals from the GPS satellite
network.
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).Should this occur, assistance must be summoned
by other means.

Roadside Assistance button 
Located below the center armrest cover is the Roadside
Assistance button. Pressing and holding the
button (for longer than 2 seconds), will initiate a call to
a Mercedes-Benz Roadside Assistance dispatcher. The
button will flash while the call is in progress. The
Tele Aid system will transmit data generating the
vehicle identification number, model, color and location
(subject to availability of cellular and GPS signals).A voice connection between the Roadside Assistance
dispatcher and the occupants of the vehicle will be
established. The nature of the need for assistance can
then be described. Sign and Drive services (jump start, a
few gallons of fuel or the replacement of a flat tire with
the vehicle spare tire) are available.
If the vehicle requires more than Sign and Drive
services, the Mercedes-Benz Roadside assistance
dispatcher will either dispatch a qualified
Mercedes-Benz technician or arrange to tow your
vehicle to the nearest Mercedes-Benz Center.
For other than Sign and Drive services, labor and / or
towing charges may apply. Refer to the Roadside
Assistance manual for more information.

Important!
Tele Aid utilizes the cellular network for
communication and the GPS (Global Positioning
System) satellites for vehicle location. If either of these
signals are unavailable, the Tele Aid system may not
function and if this occurs, assistance must be
summoned by other means.
Wa r n i n g !
The Tele Aid control unit is located under the
driver’s seat. If there is accumulation of water or
other liquid in this area, the Tele Aid control unit
could suffer an electrical short circuit making the
system inoperative. In this case the indicator lamp
in the “SOS” button does not illuminate during or
remains illuminated after the system self-check.
Have the system checked at the nearest
Mercedes-Benz Center as soon as possible.

163 Catalytic converter
Technical
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.
Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.

164 Emission control
Technical

Emission control
Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.
These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by qualified Mercedes-
Benz authorized Center technicians. Engine
a dju stments sh ould not be a ltered in a ny way. M oreover,
the specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death.Do not run the engine in confined areas (such as a
garage) which are not properly ventilated. If you
think that exhaust gas fumes are entering the
vehicle while driving, have the cause determined
and c orrec ted imm ediately. If you m ust dri ve under
these conditions, drive only with at least one
window fully open.
