Yes to both questions… Also I include info about a feature where you can program the hatch to open at a partial position.
>Using the FOB (aka Smart Key in Mercedes speak), click once (hatch icon) to open and click hold 1 second to close.
>For the interior hatch switch located on the drivers side door (lower part)>>
You can open and close the tailgate from the
driver's seat when the vehicle is stationary
and unlocked.
> To open: pull remote operating switch :
for the tailgate until the tailgate opens.
> To close: turn the SmartKey to position 1
or 2 in the ignition lock or with Keyless Go press start button without placing foot on brake (makes car go into accessory mode)
>Press remote operating switch : for the
tailgate until the tailgate is completely
closed.
You will hear a warning tone during the
closing process.
Limiting the opening angle of the tailgate
You can limit the opening angle of the tailgate.
This is possible in the top half of its
opening range.
This could be useful, for example, if there is
insufficient space above the tailgate.
! Make sure there is sufficient clearance to
open the tailgate fully when setting the
opening angle. The tailgate could otherwise
be damaged. Ideally, set the opening angle
outside.
Activating
>To open the tailgate: pull the handle on
the tailgate.
>To stop the opening procedure at the
desired position: press the closing button in the tailgate or pull the handle
on the outside of the tailgate again.
>To store the position: press and hold the
closing button in the tailgate until you hear
a short tone.
The opening angle limiter is activated. The
tailgate will now stop in the stored position
when opening.
>To open the tailgate fully, pull the handle
on the outside of the tailgate again after it
has stopped automatically. This does not
delete the stored position.
