Garage door opener
General notes
The HomeLink®garage door opener integrated
in the rear-view mirror allows you to operate up
to three different door and gate systems.
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 instruc-
tions 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:

The required distance between remote con-
trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. 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 223).
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 programming button
may be located 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 "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.
XSelect SmartKey position 2with the Start/
Stop button (Ypage 103).
XGet out of the vehicle.
XPress the programming button on the door
drive unit.
Usually, you now have 30 seconds to initiate
the next step.

XGet into the vehicle.
XPress previously programmed button;,=
or ? on the integrated garage door opener
repeatedly and in quick succession until the
door closes.
The rolling code synchronization is then com- plete.
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 open-
ers also feature a "break".
Proceed as follows:

trol Aand the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You should test every position for at least
25 seconds before trying another position.
Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote control
Aand
whether it is supported. The transmitter fre-
quency 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 likelihood that
garage door remote control Awill t
ransmit a
strong and precise signal to the integrated
garage door opener.
RWhen programming, hold remote control A
at varying distances and angles from the but-
ton which you are programming. Try various
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 pro-
gramming steps with this remote control.
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 transmit
for a limited amount of time (the indicator
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.

Engine oil
Notes on the oil level
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
It is only possible to correctly measure the oil
level when:
Rthe engine is at normal operating temperature
Rthe vehicle is parked on a level surface
Rthe engine is left running in neutral for at least
30 seconds before switching off
