Warning!
When opening or closing the tilt/sliding panel,
make sure there is no danger of anyone being
harmed by the opening/closing procedure.
The tilt/sliding panel is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
panel is blocked during the closing procedure,
the tilt/sliding panel will stop and open
slightly.
The tilt/sliding panel operates differently
when the roof panel switch is pressed and
held. See the “Closing when the tilt/sliding
panel is blocked” section in this chapter for
details.
The opening/closing procedure of the tilt/
sliding panel can be immediately halted by
releasing the roof panel switch or, if the roof
panel switch was moved past the resistance
point and released, by moving the roof panel
switch in any direction. G
Warning!
The panorama roof with tilt/sliding panel is
made out of glass. In the event of an accident,
the glass may shatter. This may result in an
opening in the roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury for
occupants wearing their seat belts properly as
entire body parts or portions of them may
protrude from the passenger compartment.
! To avoid damaging the seals, do not
transport any objects with sharp edges
which can stick out of the tilt/sliding panel.
Do not open the tilt/sliding panel if there is
snow or ice on the roof, as this could result
in malfunctions. 184

The Tele Aid system ( Telematic Alarm Identification on Demand)
The Tele Aid system consists of three types
of response:
R Automatic and manual emergency
R Roadside Assistance
R Information
The Tele Aid system is operational providing
that

the vehicle’s battery is charged, properly
connected, not damaged, and cellular and
GPS coverage is available. The Tele Aid
system utilizes the cellular network for
communication and the GPS ( Global
Positioning 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.
i A Tele Aid call cannot be canceled. Even
if the Tele Aid system is not activated or
operational, the system will attempt to
connect the respective call. This may take
as

long as five minutes or more. As long as
the Tele Aid system attempts to connect a
call, you cannot operate the COMAND
system. Also, most functions in the control
system, such as the telephone function, are
suspended. Therefore, it is not advisable to
initiate any Tele Aid call unless the Tele Aid
system is activated and operational. To adjust the speaker volume during a Tele
Aid call do the following:
X
Press button W or X on the
multifunction steering wheel.
or
X Use the adjustment button on your
COMAND system.
System self-test The system performs a self-test after you
have switched on the ignition.

not come on during the system self-test.
R The indicator lamp in Roadside Assistance

illuminated constantly in red after the
system self-test.
R The message Tele Aid Inoperative or
Tele Aid Not Activated appears in the
multifunction

display after the system self-
test
If a malfunction is indicated as outlined above,
the system may not operate as expected. In
case of an emergency, help will have to be
summoned by other means.
Have the system checked at the nearest
Mercedes-Benz Center or contact the
Response Center at 1-800-756-9018 (in the
USA) or 1-888-923-8367 (in Canada) as soon
as possible. 208

compatible with HomeLink ®
or some other
systems. G
Warning!
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
potential 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 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 unconsciousness
and possible death. Interior rear view mirror with integrated remote

approximately 20 seconds.
Do not hold the buttons for longer than
30 seconds.
This procedure erases any previous
settings for all three channels and
initializes the memory. If you later wish to
program a second and/or third hand-held
transmitter to the remaining two signal
transmitter buttons, do not repeat this step
and begin directly with step 3.

If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming
procedures, replace step 4 with
the following:
X Step 4: Press and hold the signal
transmitter button ( ;, = or ?). Do not

Refueling
G
Warning!
Gasoline and diesel fuels are highly flammable
and poisonous. They burn violently and can
cause serious injury.
Never allow sparks, flames or smoking
materials near gasoline or diesel fuel!
Turn off the engine before refueling.
Whenever you are around gasoline or diesel
fuel, avoid inhaling fumes and any skin or
clothing contact. Extinguish all smoking
materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health. G
Warning!
Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gas to
spray

back out when removing the fuel pump
nozzle, which could cause personal injury. G
Warning!
Do not fill diesel tanks with gasoline. Do not
mix diesel fuel with gasoline. Otherwise the
fuel

system and engine could be damaged. In
addition, the vehicle could catch fire.
! Never use diesel fuel in vehicles with
gasoline engine. Never refuel vehicles with
gasoline engine with diesel fuel. Even small
amounts of incorrect fuel will damage the
fuel system and engine. Damage resulting
from the use of non-approved fuels or fuel
additives or resulting from mixing gasoline
with diesel fuel or vice versa is not covered
by the Mercedes-Benz Limited Warranty.
! If you have accidentally filled the tank
with incorrect or non-approved fuel, do not
switch on the ignition. Otherwise the
incorrect or non-approved fuel will get into
the fuel lines. The fuel system must be 220
