Important safety notes In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
G WARNING
While opening and closing the sliding sunroof,
body parts in close proximity could become

proximity during the opening and closing pro-
cedures. If somebody becomes trapped: R

Opening and closing Z

G WARNING
At high speeds the raised sliding sunroof auto-
matically lowers slightly at the rear. This could
trap you or other persons. There is a risk of
injury. Make sure that nobody reaches into
the sweep of the sliding sunroof whilst the
vehicle is in motion.
If somebody becomes trapped, immediately
push the sliding sunroof switch up or pull it
back. The sliding sunroof raises at the rear.
! Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be
damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the slid-
ing sunroof is closed when you leave the vehi-
cle. The vehicle electronics can be damaged if
water enters the vehicle interior.
! When the sliding sunroof is open, water can
get into the vehicle and cause damage. The
vehicle electronics can be damaged if water
enters the vehicle interior. Only clean the slid-
ing sunroof when it is closed.
Resonance noises can occur in addition to the
usual airflow noises when the sliding sunroof is
open. They are caused by minor pressure fluc-
tuations in the vehicle interior. Change the posi-
tion of the sliding sunroof or open a side window
slightly to reduce or eliminate these noises.
Sliding sunroof reversing feature The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. The automatic reversing feature is
only an aid and is no substitute for your attention
when closing the sliding roof. G WARNING
The reversing feature does not react: R
to soft, light and thin objects, e.g. small fin-
gers R
over the last 1/6 in (4 mm) of the closing
movement R
during resetting R
when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped: R
release the switch immediately, or R
press the switch in any direction during the
automatic closing process
The closing process is stopped.

automatic operation by pressing or pulling
again.
If the sliding sunroof is raised at the rear, it low-
ers slightly automatically at higher speeds. The

carrier is installed. In order to allow ventilation
of the vehicle interior, you can raise the sliding
sunroof.
If contact is made with a roof carrier approved
by Mercedes-Benz, the sliding sunroof lowers
slightly but remains raised at the rear.
Before opening, raising or closing the sliding
sunroof, a check is carried out to see whether a
valid SmartKey is in the vehicle, if: R
the W switch is pressed or pulled
and R
the Start/Stop button is used instead of the
SmartKey in the ignition lock
and R
the engine is not running
This is carried out by means of a brief radio con-
nection between the vehicle and the SmartKey.

at the rear when driving if it starts to rain. The
sliding sunroof is lowered depending on: R
the road speed and R
the intensity of the rain
You can manually cancel the automatic closing
procedure. Press or pull the W switch in any
direction.

matically. The automatic reversing feature is
only an aid and is not a substitute for your atten-
tion when closing the roller sunblinds.
G WARNING

ticular to soft, light and thin objects, e.g. small
fingers. This means that the reversing feature

that no body parts are in the sweep area.
If somebody becomes trapped: R
release the switch immediately, or R
