escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not al-
low the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.Warning!

the multifunction display.
iThe SOS button is located above the in-
terior rear view mirror.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest cov-
er.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites 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.
Warning!

240 Controls in detailUseful featuresEmergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) 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
briefly pressing the button located under
the cover. See (
page 241) 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.

signals from the GPS satellite network
and pass the information on to the
Response Center.

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

10 seconds.
Should this occur, assistance must be sum-
moned by other means.

Garage door opener
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to re-
place up to three hand-held remote con-
trols used to operate devices such as
garage door openers, gate openers, or oth-
er devices compatible with HomeLink
® or
some other systems.
Before the integrated remote control can
be used, it must be programmed to the ga-
rage door opener, gate operator or other
device you wish to operate. See the follow-
ing instructions for programming informa-
tion.

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.
324 OperationVehicle careHand-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.
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.
!Due to the width of the vehicle, fold in
exterior rear view mirrors prior to run-
ning the vehicle through an automatic
car wash to prevent damage to the
mirrors.
Make sure that the windshield wiper
switch is set to0 (
page 54). Other-
wise, the rain sensor could activate and
cause the wipers to move unintention-
ally. This may lead to vehicle damage.
iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 327). This will
prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
When leaving the car wash, make sure
that the mirrors are folded out. Other-
wise they may vibrate.
