2015 MERCEDES-BENZ A-CLASS HATCHBACK roof

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 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. Reversing feature of the sliding sun-
roof
In the following section, the term "sliding sun- roof" refers to the panorama sliding sunroof.
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, however, only an aid and is no substi-
tute for your attention when closing the slid-
ing 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 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.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R release the switch immediately or
R press the switch in any direction during the
automatic closing process

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
General 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 activate air-recirculation mode only briefly
R activate the "Cooling with air dehumidifica-
tion" function
R activate the windscreen demisting function
briefly, if required
The air-conditioning system/
THERMOTRONIC automatic climate control
regulates the temperature and the humidity
of the vehicle interior and filters undesirable
substances from the air.
The air-conditioning system/
THERMOTRONIC automatic climate control
can only be operated when the engine is run-
ning. 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 147).
Always keep the ventilation flaps behind the
side panelling clear (Y page 128). 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 95). 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 Vehicles with auxiliary heating:
under
certain environmental conditions, the
residual heat function may be activated
automatically an hour after the key has
been removed in order to dry the automatic climate control. When the automatic cli-
mate control drying function is active, the
blue LED lamp is lit in the rocker switch in
the centre console. The vehicle is then ven-
tilated for 30 minutes.
Vehicles without auxiliary heating:
under certain environmental conditions,
the residual heat function may be activated automatically an hour after the key has
been removed in order to dry the automatic
climate control. The vehicle is then ventila-
ted for 30 minutes. 136

on/off
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 activate air-recirculation mode, the win-
dows can mist up more quickly, in particular
at low temperatures. Only use air-recircula-
tion mode briefly to prevent the windows
misting up.
The operation of air-recirculation mode is the same for all control panels.
