The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.Maintenance
Approximately 30 days or 2000 miles (2000 km) prior to
the next recommended service, the remaining distance
or days are displayed in the main odometer field. See
Flexible service system on page 80.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Center, in
accordance with the Service Booklet at the times called
for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times/
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.

and controlsOperationDrivingInstrument
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.
