the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance. The use of the guide lines to judge
distance increases the risk of impacting the
objects.

e-
mand)
The Tele Aid system consists of three
types of response:


automatic and manual emergency


roadside assistance, and


informationThe Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and mo-
bile phone and GPS coverage are 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 COMAND
volume thumbwheel , on the lower
part of the front central console
(
page 89).

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.
If a malfunction is detected, the indicator
lamps in the SOS button, the Roadside As-
sistance button• and the Information
button¡ stay on longer than
10 seconds or do not come on. The mes-
sage “Tele Aid not activated” or “Tele Aid
inoperative” appears in the multifunction
display.
!
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 Information 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
1-888-923-8367 (in Canada).
i
The Tele Aid system utilizes the mobile
phone network for communication and the GPS
(Global Positioning System) satellites for vehicle
location. If either of these signals are unavail-
able, the Tele Aid system may not function and if
this occurs, assistance must be summoned by
other means.
i
The SOS button is located above the interior
rear view mirror (
page 464).
The Roadside Assistance button• and the
Information button¡ are located below the

such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), 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 acci-
dent provided they can speak to an
occupant of the vehicle.
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 during the system self-check,
or if any of these indicators remain illuminat-
ed continuously in red and/or the message

pected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
i
During the emergency call message “Emer-
gency Call Activated” is displayed, operation
from COMAND is not possible. The automatic cli-
mate control can be still adjusted using the

lance will be sent to the vehicle immediately.

470 Controls in detailUseful featuresGarage 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.
When programming a garage door opener,
park the vehicle outside the garage.

536 OperationVehicle careEngine 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 Anticorrosion Wax, should be applied
to the engine compartment after every en-
gine cleaning. Before applying, all control
linkage bushings and joints should be lu-
bricated. 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 vehicle underbody, do
not forget 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 vehicle washed in an au-
tomatic 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.
i
Vehicles with KEYLESS-GO*:
If a door handle is hit by a strong jet of water, and
a SmartKey with KEYLESS-GO* is in close prox-
imity, i.e. within approximately 3 ft (approxi-
mately 1 m), the vehicle could be inadvertently
locked or unlocked.
!
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.
!
Due to the width of the vehicle, fold in
exterior rear view mirrors prior to running the ve-
hicle through an automatic car wash to prevent
damage to the mirrors.
Make sure that the windshield wiper switch is set
to0 (page 351). Otherwise, the rain sensor
could activate and cause the wipers to move un-
intentionally. This may lead to vehicle damage.
i
After running the vehicle through an auto-
matic car wash, wipe any wax off of the wind-
shield (
page 540). 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. Otherwise they may vi-
brate.

Notes on bulb replacement


Only use 12-volt-bulbs of the same
type and with the specified watt rating.


Switch lights off before changing a bulb
to prevent short circuits.


Always use a clean lint-free cloth when
handling bulbs.


Your hands should be dry and free of oil
and grease.


If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.
Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.


the Bi-Xenon lamps


the front turn signal lamps


the front fog lamps


the additional turn signal lamps in the
exterior rear view mirrors

Replacing bulbs for front lamps
Before you start to replace a bulb for a
front lamp, do the following first:
Turn the exterior lamp switch to M
(page 342).

Open the hood (
page 492) (except
for side marker lamps).
Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:

touch or move it when hot


drop the bulb


scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
