Problems with the side windows
G WARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing feature is then not active. Parts of the
body could be trapped in the closing area in the process. This poses an increased risk of injury or
even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, release
the switch or push the switch again to reopen the side window.
Problem
Possible causes/consequences and P Solutions
A side window cannot be
closed because it is

Panorama roof with power tilt/sliding
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.
Make sure that no body parts are in close
proximity during the opening and closing pro-
cedures. 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.
G WARNING
If children operate the sliding sunroof they
could become trapped, particularly if they are
left unsupervised. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.Panorama roof with power tilt/sliding panel 93
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
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.

open a front door.
When a roof carrier is mounted the panorama
roof with power tilt/sliding panel cannot be
opened. The panorama roof with power tilt/slid-
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
the intensity of the rain
You can manually cancel the automatic closing
procedure. Press or pull the W switch in any
direction.
To raise the panorama roof with power tilt/slid-
ing panel again, press the W switch in direc-

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

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.

Overview of climate control systems
General notes Observe the settings recommended on the fol-
lowing pages. The windows could otherwise fog
up.
To prevent the windows from fogging up: R
switch off climate control only briefly R
switch on air-recirculation mode only briefly R
switch on the cooling with air dehumidifica-
tion function R
activate the "Windshield defrosting" function
briefly, if required
Climate control regulates the temperature and
air humidity in the vehicle interior. The interior
filter cleans the air, thus improving the interior
climate.
The "Cooling with air dehumidification" function
is only available when the engine is running.
Optimum climate control is only achieved with
the side windows and roof closed.
If you start the engine using your smartphone,
the last selected climate control setting is reac-
tivated ( Y
page 134). The integrated filter filters out most particles of
dust and soot and completely filters out pollen.
It also reduces gaseous pollutants and odors. A
clogged filter reduces the amount of air supplied
to the vehicle interior. For this reason, you
should always observe the interval for replacing
the filter, which is specified in the Maintenance
Booklet. As it depends on environmental condi-
tions, e.g. heavy air pollution, the interval may
be shorter than stated in the Maintenance Book-
let.
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the convenience
opening feature ( Y
page 91). This will speed
up the cooling process and the desired inte-
rior temperature will be reached more
quickly.
i It is possible that the blower may be activa-
ted automatically 60 minutes after the Smart-
Key has been removed depending on various
factors, e.g. the outside temperature. The
vehicle is then ventilated for 30 minutes to dry
the automatic climate control.
