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 function 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, releasethe switch or push the switch again to reopen the side window. Problem
Possible causes/consequences and
M MSolutions A side window cannot
be closed because it is
blocked by objects, e.g.
leaves in the window
guide. X
Remove the objects.
X Close the side window. A side window cannot
be closed and you can-
not see the cause. If a side window is obstructed during closing and reopens again
slightly:
X Immediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed with increased force.
If a side window is obstructed again during closing and reopens
again slightly: X Immediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed without the anti-entrapment feature. Panorama sliding sunroof
Important safety notes
In the following section, the term "sliding sun-
roof" refers to the panorama sliding sunroof. 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, press 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 key
with you and lock the vehicle. Never leave
children unattended in the vehicle. Panorama sliding sunroof

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 panorama sliding sunroof if
it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could
be damaged.
i Resonance noises can occur in addition to
the usual airflow noises when the sliding
sunroof is open. They are caused by minor
pressure fluctuations in the vehicle interior.
Change the position 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 an object blocks or restricts the sliding sunroof during the closing
process, the sliding sunroof opens again
automatically. The automatic reversing fea-
ture is only an aid and is no substitute for your attention when closing the sliding roof. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R over the last 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 function cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area.
If someone is trapped:
R release the switch immediately or
R during automatic operation, press the
switch briefly in any direction

WARNING
If you do not reset the sliding sunroof after a malfunction or voltage supply interruption, then the
reversing function will malfunction or not work. The sliding sunroof closes with increased or
maximum force. 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.
In such or similar situations always make sure that no parts of the body are in the closing area.
Always reset the sliding sunroof after a malfunction or voltage supply interruption. Problem

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 24). Overview of climate control systems
Important safety notes
Observe the settings recommended on the
following pages. The windows could other-
wise mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R switch on air-recirculation mode only
briefly
R switch on the cooling with air dehumidifi-
cation function
R switch on the "demist windscreen" function
briefly, if required
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters out undesir-
able substances from the air.
THERMATIC automatic climate control/
THERMOTRONIC automatic climate control is only operational when the engine is running.
Optimum operation is only achieved with the
side windows and panorama sliding sunroof
closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 137).
Always keep the ventilation flaps behind the
side panelling clear (Y page 120). Otherwise,
the vehicle will not be ventilated correctly. i
Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 90). This
will speed up the cooling process and the
desired interior temperature will be
reached more quickly.
i The integrated filter filters out most par-
ticles of dust and soot and completely fil-
ters out pollen. With THERMOTRONIC auto- matic climate control, gaseous pollutants
and odours will also be reduced. 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 Service Booklet. As this depends on envi-
ronmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than statedin the Service Booklet.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key has been removed in order to
dry the automatic climate control. The vehi- cle is then ventilated for 30 minutes. 126

Problems with the rear window heating
Problem
Possible causes/consequences and
M
MSolutions The rear window heat-
ing has switched off
prematurely or cannot
be activated. The battery has not been sufficiently charged.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window heat- ing can be activated again. Activating/deactivating air-recircula-
tion mode
General notes You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated.
If you switch on air-recirculation mode, the
windows can mist up more quickly, in partic-
ular at low temperatures. Only use air-recir-
culation mode briefly to prevent the windows misting up.
The operation of air-recirculation mode is thesame for all control panels.
Activating/deactivating X
Turn the key to position 2in the ignition
lock (Y page 147).
X To activate: press theebutton.

after about 30 minutes.
X To deactivate: press theebutton.
The indicator lamp in the ebutton goes
out. i
Air-recirculation mode is deactivated
automatically:
R after approximately five minutes at out-
side temperatures below about 5 †
R after approximately five minutes if the
"Cooling with air dehumidification" func-
tion is deactivated
R after approximately 30 minutes at out-
side temperatures above approximately
