The Tele Aid system
(Tele
matic Alarm Identification on De-
mand)
The Tele Aid system consists of three
types of response:
Automatic and manual emergency
Roadside Assistance
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.Shortly after the completion of your Tele
Aid acquaintance call, you will receive a
user ID and password. By visiting
www.mbusa.com and selecting “Tele Aid”
(USA only), you will have access to account
information, remote door unlock, and
more.
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 Inoperative appears
for approximately 10 seconds in the multi-
function display.
iThe SOS button is located above the interior
rear view mirror (
page 253).
The Roadside Assistance button• and the
Information button¡ are located below the
center armrest cover (
page 239).
!The Tele Aid system utilizes the cellular
network for communication and the GPS (Global
Positioning System) satellites for vehicle loca-
tion. 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.
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
Inoperative
is displayed in the multifunc-
tion 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.

Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 253) for instruc-
tions on initiating an emergency call man-
ually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting Call
appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
Call Connected appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion 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 af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the
emergency 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, connection and
cellular air time.
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center
iLocation of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.
Warning!G
If the indicator lamp in the SOS button is
flashing 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 rele-
vant cellular phone network is not available).
The message
Call Failed appears in the
multifunction display for approximately
10 seconds.
Should this occur, assistance must be sum-
moned by other means.

Warning!G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
– signaling the door to stop and reverse –
does not meet current U.S. federal safety
standards.
When programming a garage door opener,
park the vehicle outside the garage.
Do not run the engine while programming
the integrated remote control.
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause un-

Vehicle care
Engine cleaning
Prior to cleaning the engine compartment,
make sure to protect electrical compo-
nents and connectors from contact with
water and cleaning agents.
Corrosion protection, such as MB Anticor-
rosion Wax, should be applied to the
engine compartment after every engine
cleaning. Before applying, all control
linkage bushings and joints should be
lubricated. The poly-V-belt and all pulleys
should be protected from any wax.
Vehicle washing
In the winter, thoroughly remove all traces
of road salt as soon as possible.
When washing the underbody, do not for-
get to clean the inner sides of the wheels.Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
such as Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the vehicle with a dif-
fused jet of water.
Direct only a very weak spray towards
the ventilation intake.
Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clean water and thoroughly
dry with a chamois.
Do not allow cleaning agents to dry on
the finish.Automatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
To protect the filter system, switch the
automatic climate control to air
recirculation mode (
page 196).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
iVehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of water,
and a SmartKey with KEYLESS-GO* is in close
proximity, i.e. within approximately 3 ft (1 m),
the vehicle could be inadvertently locked or
unlocked.!Do not use scouring agents on these parts.
Never apply strong force and only use a soft,
non-scratching cloth when cleaning the vehicle.
Do not attempt to wipe the surface with a dry
cloth or sponge.
Otherwise you may scratch or damage the paint.
!Do not clean your vehicle in an automatic
touchless car wash which uses caustic spray.
Otherwise, the caustic spray will damage the
paint or ornamental moldings.
!Make sure that the windshield wiper switch
is set to0 (
page 58). Otherwise, the rain sen-
sor could activate and cause the wipers to move
unintentionally. This may lead to vehicle dam-
age.
Due to the width of the vehicle, fold in exterior
rear view mirrors prior to running the vehicle
through an automatic car wash to prevent dam-
age to the mirrors.
