cluster displayPractical hints Car care Index 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 page 42 and page 43.
An emergency call can also be initiated manually by
opening the cover next to the interior rear view mirror
labeled “SOS”, then 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 f lash. 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. 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
• the relevant cellular phone network and GPS signals
are available pass the information on to the
Response Center.
Note:
Location of the vehicle on a map is possible if the
vehicle is able to receive signals from the GPS satellite
network pass the information on to the Response
Center.
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 oth er means.

Important!
If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in
red) at any time, the Tele Aid system has detected a fault
or the service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Center and
have the system checked or contact the Response Center
at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada) as soon as possible.Upgrade Signals
Tele Aid system processes calls using the following
priority.
• Automatic emergency – First priority
• Manual emergency – Second priority
• Roadside assistance – Third priority
• Information – Fourth priority
Should a higher priority call be initiated while you are
connected, an upgrade (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
client information is not available, the operator may
need to retransmit. During this time you will hear a
chirp and voice contact will be interrupted. Voice
contact will resume once the retransmission is
completed. Once a call is concluded, a chirp will be
heard and the appropriate indicator lamp will stop
flashing. The audio system operation will resume.

Notes:
The indicator lamp in the respective button f lashes until
the call is concluded and this can only be completed by
a Response Center or Client Assistance Center
representative.
When a Tele Aid call has been initiated, the audio
system is muted and the selected mode (radio, tape or
CD) pauses. The optional cellular phone (if installed)
switches off. If you must use this phone, the vehicle
must be parked. Disconnect the coiled cord and place
the call. Stolen vehicle tracking services
In the event your vehicle was stolen, report the incident
to the police who will issue a numbered incident report.
Pass this number on to the Mercedes-Benz Response
Center.
The Response Center will then attempt to covertly
contact the vehicle’s Tele Aid system. Once the vehicle
is located, the Response Center will contact the local
Law Enforcement and you. The vehicle’s location will
only be provided to Law Enforcement.
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.

163 Catalytic converter
Te ch n ica l
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.

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
adjustments should not be altered in any way. Moreover,
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 corrected immediately. If you must drive under
these conditions, drive only with at least one
window fully open.

Notes:
A warning sounds when the driver’s door is opened
while the key is in steering lock position 1 or 0.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster.Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.
