panel
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
trapped. There is a risk of injury.

Panorama roof with power tilt/sliding panel
Opening and closing

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
pull back the sliding sunroof switch. The slid-
ing sunroof lifts during opening.
! 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.
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 In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
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.

ing panel can still be raised to allow ventilation
of the vehicle interior. If the panorama roof with
power tilt/sliding panel makes contact with a
roof carrier approved by Mercedes-Benz, the
sunroof will lower slightly but remain raised at
the rear.
Rain-closing feature The raised panorama roof with power tilt/sliding
panel automatically lowers when driving if it
starts to rain. The sliding sunroof is lowered
depending on: R
the road speed R

panorama roof with power tilt/sliding
panel
Important safety notes
G WARNING
Parts of the body could become trapped
between the roller sunblind and frame or slid-
ing sunroof during automatic opening or clos-
ing. There is a risk of injury.
When opening or closing, make sure that no
body parts are in the sweep of the roller sun-
blind.
If somebody becomes trapped: R
release the switch immediately, or R
during automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop-
ped.
The roller sunblinds shield the vehicle interior
from sunlight. The roller sunblinds can only be
opened and closed when the panorama roof
with power tilt/sliding panel is closed.
Roller sunblind reversing feature The roller sunblinds are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a roller sunblind during the closing
process, the roller sunblind opens again auto-
matically. However, the automatic reversing
feature is only an aid and is not a substitute of
your attentiveness when closing the roller sun-
blind.
G WARNING
The reversing feature does not react in par-
ticular to soft, light and thin objects, e.g. small
fingers. This means that the reversing feature
cannot prevent someone being trapped in
these situations. There is a risk of injury.
When closing the roller sunblind, make sure
that no body parts are in the sweep area.96

The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the

the windshield near the overhead control panel.
Important safety notes
G WARNING
Adaptive Highbeam Assist does not recognize
road users: R
who have no lights, e.g. pedestrians R
who have poor lighting, e.g. cyclists R
whose lighting is blocked, e.g. by a barrier
On very rare occasions, Adaptive Highbeam
Assist may fail to recognize other road users
that have lights, or may recognize them too
late. In this, or in similar situations, the auto-
matic high-beam headlamps will not be deac-
tivated or will be activated regardless. There is
a risk of an accident.
Always carefully observe the traffic conditions
and switch off the high-beam headlamps in
good time.
Adaptive Highbeam Assist cannot take into
account road, weather or traffic conditions.
Adaptive Highbeam Assist is only an aid. You are
responsible for adjusting the vehicle's lighting
to the prevailing light, visibility and traffic con-
ditions.
In particular, the detection of obstacles can be
impaired if: R
there is poor visibility, e.g. due to fog, heavy
rain or snow R
there is dirt on the sensors or anything else
covering the sensors
