Problems with the roof
Problem Possible causes/consequences and
0001 Solutions
The roof will not open or
close. The trunk partition is not closed and not properly engaged.
X
Close the trunk partition (Y page 85). The trunk lid is open.
X
Close the trunk lid (Y page 77). The on-board voltage is too low.
X
Leave the engine running. The roof has been opened and closed several times in
arow. The
roof drive has been automatically deactivated.
You can open and close the roof again after approximately ten
minutes.
X Switch off the ignition and turn it back on.
X Repeat the opening or closing procedure. The automatic roof mechanism is faulty.

Consult a qualified specialist workshop. Wind screen
General notes The wind screen offers protection from the
wind when driving with the roof down.
G
WARNING
You could lose control of the vehicle and
injure yourself or others if you operate the
wind screen while driving.
Install or remove the wind screen only when
the vehicle is stationary. G
WARNING
If you use the wind screen in darkness or in
other conditions offering poor visibility, your
view to the rear is further impaired. As a result
of the visibility impairment, you could cause
an accident and injure yourself or others.
For this reason, remove the wind screen as
soon as it is dark or if your vision is otherwise
restricted. G
WARNING
If the wind screen is not correctly engaged, it
may break free and thus obstruct traffic
behind you or lead to an accident.
Each time before driving with the roof down,
check that the wind screen is properly
engaged.
! Install or remove the wind screen only
when the roof is open. You could otherwise
damage the wind screen or the vehicle
interior.
The wind screen can be installed or removed
from the driver's side or passenger side.
Perform operations involving the wind screen
preferably on the side facing away from
traffic, after you have stopped the vehicle,
paying attention to road and traffic
conditions. 86

Ris
kofe lectric shock The electrical components of MAGIC SKY
CONTROL are protected by a covering behind
the overhead control panel.
The MAGIC SKY CONTROL control unit is
marked with a yellow warning sticker that
warns you of high voltage. The high-voltage
cables are orange in color. G
DANGER
The MAGIC SKY CONTROL electrical system
works at high voltage.
If the cover behind the overhead control unit
is damaged or is removed, electrical
components of MAGIC SKY CONTROL are
exposed. These may be live. If you touch these
components, you may get an electric shock
and could be seriously or even fatally injured.
For this reason, never remove the cover
behind the overhead control unit .Never touch
parts of the electrical system (control unit,
cables or cable connections).
Have all work on MAGIC SKY CONTROL
carried out at a qualified specialist workshop.

If yourv
ehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 110). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs,
consult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint-
free cloth or only touch the base of the bulb
when installing.
Only use bulbs of the correct type.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly. G
WARNING
Bulbs and lamps can become very hot. For
this reason, allow them to cool down before
changing them. Otherwise, you could burn
yourself when you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could, for example, damage
the bulbs and injure themselves.
Never use a bulb which has been dropped.
Such a bulb may explode and injure you.
Halogen bulbs are pressurized and could
explode when you change them, especially if they are very hot. You should therefore wear
eye protection and gloves when you are
changing them. Overview: changing bulbs/bulb types
You can change the following bulbs. The bulb
type can be found in the legend. Halogen headlamps

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 23).Overview of climate control systems
Important safety notes
G
WARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. Aclogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a blocked filter replaced at a Mercedes-
Ben zCenter as soon as possible. G
WARNING
Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.
The air-conditioning system/automatic
climate control controls the temperature and
the humidity of the vehicle interior and filters
undesirable substances from the air.
The air-conditioning system/automatic
climate control is only operational when the
engine is running. 7
The system only works
optimally when the side windows and the roof
are closed. i
Ventilate the vehicle for a brief period
during warm weather. This will speed up the
cooling process and the desired vehicle
interior temperature will be reached more
quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged 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 conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.

Important information G
WARNING
When the climate control system is switched
off, the outside air supply and circulation are
also switched off. Only choose this setting for
a short time when the retractable hardtop
(vario-roof) is closed. Otherwise, the windows
could fog up, impairing visibility and
endangering you and others.
i Activate climate control primarily using
the 0005 button (Y page 122).

air dehumidification
Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.
G
WARNING
If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a
malfunction.
Depending on the equipment level, the
control panel has either the 0004button or
0006 button.
i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer. Operating the climate control systems
