Sun visors
The sun visors protect you from sun glare
while driving.

Warning!G
In case of an accident, liquid electrolyte may
escape from the mirror housing if the mirror
glass breaks.
Electrolyte has an irritating effect. Do not
allow 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 and by
applying plenty of water.
Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
Warning!G
Do not use the driver’s side vanity mirror
while driving.
Keep the mirrors in the sun visors closed
while vehicle is in motion. Reflected glare
can endanger you and/or others.

Tele Aid
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.The Tele Aid system
(Tele
matic Alarm Identification on
D
emand)
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
cellular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the audio system or on the multifunc-
tion steering wheel. To raise, turn the rota-
ry volume control on the audio system
clockwise or press buttonæ on the
multifunction steering wheel. To lower,
turn the rotary volume control on the audio
system control counterclockwise or press
buttonç on the multifunction steering
wheel.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
!The initial activation of the Tele Aid system
may only be performed by completing the sub-
scriber agreement and placing an acquaintance
call using the ¡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
1-800-387-0100 (in Canada).
iThe SOS button is located above the inside
rear view mirror (
page 217).
The Roadside Assistance button•
(
page 217) and the Information button¡
(
page 218) are located in the center storage
compartment.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (
Global Po-
sitioning
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.
iWhen a Tele Aid call has been initiated, the
audio system is muted and the selected mode
(radio or CD) pauses. The mobile phone (if in-
stalled) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle at a standstill in a safe location. Remove
the phone from the cradle and place the call. The
multifunction display in the instrument cluster is
available for use. After the Tele Aid call has end-
ed, the optional mobile phone switches on again.
A PIN entry might be necessary.

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 multifunction display.Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or air bags have deployed.
An emergency call can also be initiated
manually by opening the cover next to the
inside rear view mirror labeled SOS, then
briefly pressing the button located under
the cover.
For more information, see “Initiating an
emergency call manually” (
page 217).

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.

Stolen Vehicle Recovery services
In the event your vehicle was stolen:
Report the incident to the police.
The police will issue a numbered
incident report.
Pass this number on to the
Mercedes-Benz Response Center along
with your password issued to you when
you subscribed to the service.
The Response Center will then attempt
to covertly contact the vehicle’s Tele
Aid system. Once the vehicle is locat-
ed, the Response Center will contact
the local law enforcement and you. The
vehicle’s location will only be provided
to law enforcement.
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
other 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
information.

Vehicle care
Vehicle washing
Hand-wash
Do not use hot water or wash your vehicle
in direct sunlight.
Only use a mild car wash detergent,
which is recommended by
Mercedes-Benz.
Only use a soft sponge or a washing
brush.
Thoroughly spray the vehicle with a
diffused 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
preferable.
To protect the filter system, switch the
automatic climate control to air
recirculation mode (
page 195).
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.!When washing the vehicle, fine and rigid
particles in sponges or brushes could scratch or
otherwise damage the paint. This applies to
both, hand-wash or automatic car wash.
Mercedes-Benz recommends you to have your
vehicle cleaned at an automatic car wash from
the start, preferably one without brushes, or to
use plenty of water when hand-washing your
vehicle.
Do not wash the car in direct sunlight and when
the body surface is hot.
In the winter, remove salt residue quickly and
thoroughly.
!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 52). Otherwise, the rain
sensor could activate and cause the wipers to
move unintentionally. This may lead to vehicle
damage.
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
damage to the mirrors.
iAfter running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 297). This will prevent smears
and reduce wiping noise which can be caused by
residual wax on the windshield.
