Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 55.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 107).
i After switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the tilt/sliding
sunroof until you open the driver’s or front
passenger door. If no door was opened you

Loading instructions
GWarning!
Always fasten items being carried as securely
as possible. Use cargo tie-down rings and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.

equipped, always use the cargo net when
transporting cargo.
Unless you are transporting cargo, the seat
backrests must remain properly locked in the
upright position.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
Always use the cargo tie-down rings.
GWarning!
Never drive a vehicle with the tailgate open.
Deadly carbon monoxide (CO) gases may
