Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 56.GWarning!
When opening or closing the tilt/sliding
sunroof, make sure there is no danger of
anyone being harmed by the opening/closing
procedure.
The tilt/sliding sunroof is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
sunroof is blocked during the closing
procedure, the tilt/sliding sunroof will stop
and open slightly.
The tilt/sliding sunroof operates differently
when the sunroof switch is pressed and held.
See the “Closing when the tilt/sliding sunroof
is blocked” section for details.
The opening/closing procedure of the tilt/
sliding sunroof can be immediately halted by
releasing the sunroof switch or, if the sunroof
switch was moved past the resistance point
and released, by moving the sunroof switch in
any direction.
GWarning!
The tilt/sliding sunroof 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
sunroof.
Do not open the tilt/sliding sunroof if there
is snow or ice on the roof, as this could
result in malfunctions.
If you cannot open or close the tilt/sliding
sunroof due to a malfunction contact
Roadside Assistance or an authorized
Mercedes-Benz Center.
!  Please keep in mind that weather
conditions can sometimes change rapidly.
Make sure to close the tilt/sliding sunroof
when leaving the vehicle. If water enters
the vehicle interior, vehicle electronics
could be damaged which is not covered by
the Mercedes-Benz Limited Warranty.
i You can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO function, see “Summer
opening feature” ( Y page 107) and
“Convenience closing feature”
( Y  page 108).

Garage door opener
The integrated remote control can operate up
to three separately controlled devices
compatible with HomeLink ®
 or some other
systems.
GWarning!
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.
