Garage door opener
General notes
The HomeLink®garage door opener integra-
ted in the rear-view mirror allows you to oper-
ate up to three different door and gate sys-
tems.
Use the integrated garage door opener only
on garage doors that:
Rhave safety stop and reverse features and
Rmeet current U.S. federal safety standards
Once programed, the integrated garage door
opener in the rear-view mirror will assume the
function of the garage door system's remote
control. Please also read the operating
instructions for the garage door system.
When programming a garage door opener,
park the vehicle outside the garage. Do not
run the engine while programming.
Certain garage door drives are incompatible
with the integrated garage door opener. If you
have difficulty programing the integrated
garage door opener, contact an authorized
Mercedes-Benz Center.
Alternatively, you can call the following tele-
phone assistance services:
RUSA: Mercedes-Benz Customer Assistance
Center at 1-800-FOR-MERCedes

Important safety notes
GWARNING
When you operate or program the garage door
with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

opener depends on the garage door drive
system. Several attempts might be neces-
sary. You should test every position for at
least 25 seconds before trying another
position.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(
Ypage 257).
If the garage door system uses a rolling code,
you will also have to synchronize the garage

door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. The program-
ming button may be positioned in different
places depending on the manufacturer. It is
usually located on the door drive unit on the
garage ceiling.
Familiarize yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within reach of the
garage door or gate opener drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
XTurn the SmartKey to position2in the igni-
tion lock (

XGet out of the vehicle.
XPress the programming button on the door drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
XGet into the vehicle.
XPress previously programmed button ;,
= or? on the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
Notes on programming the remote con-
trol
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds. Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also fea-
ture a "break". Proceed as follows:
Rif you live in Canada
Rif you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps.

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the
rear-view mirror, take note of the following
instructions:
RCheck the transmitter frequency used by
garage door drive remote controlAand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
RReplace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to
the integrated garage door opener.
RWhen programming, hold remote control
A at varying distances and angles from the
button which you are programming. Try var-
ious angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
RIf another remote control is available for the
same garage door drive, repeat the same
programming steps with this remote con-
trol. Before performing these steps, make
sure that new batteries have been installed
in garage door drive remote control A.
RNote that some remote controls only trans-
mit for a limited amount of time (the indi-
cator lamp on the remote control goes out).
Press buttonBon remote control Aagain
before transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control. Please also read the operating instructions
for the garage door system.
XTurn the SmartKey to position
2in the igni-
tion lock (
Ypage 137).
XPress button ;,=or? which you have
programmed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp :lights up green.
Garage door system with a rolling code:

long as the button is pressed. The trans-
mission is halted after a maximum of ten
seconds and indicator lamp :lights up
yellow.
XPress button ;,=or? again if neces-
sary.
Clearing the memory
Make sure that you clear the memory of the
integrated garage door opener before selling
the vehicle.
XTurn the SmartKey to position 2in the igni-
tion lock (

GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use

Engine compartment
Hood
Important safety notes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is a risk of an accident.
Never unlatch the hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
The engine compartment contains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is a risk of injury.
If you need to do any work inside the engine
compartment:
Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts
GWARNING
The ignition system and the fuel injection sys-
tem work under high voltage. If you touch
components which are under voltage, you
could get an electric shock. There is a risk of
injury.
Never touch components of the ignition sys-
tem or fuel injection system when the ignition
is switched on.
GWARNING
Hybrid vehicles: be sure to read the "HYBRID" supplement. Otherwise, you could fail to rec-
ognize dangers.
Opening the hood
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
