R STEER CONTROL (Y page 75) Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither reduce the risk of an accident nor
override the laws of physics. Driving safety
systems are merely aids designed to assist
driving. You are responsible for maintaining
the distance to the vehicle in front, for vehicle
speed, for braking in good time and for stay-
ing in lane. Always adapt your driving style to
suit the prevailing road and weather condi-
tions and maintain a safe distance from the
vehicle in front. Drive carefully. Driving safety systems

General notes MAGIC SKY CONTROL is a glass roof, the
transparency of which can be changed by
applying electrical voltage.
MAGIC SKY CONTROL can be switched
between darkened and transparent states.
i MAGIC SKY CONTROL darkens automat-
ically after a short period when you turn the SmartKey to position 0or remove it.
Risk of electric shock G
DANGER
MAGIC SKY CONTROL operates using high
voltage. If the headliner behind the panorama roof is damaged or removed, electrical com-
ponents will be exposed. If you touch these
components, you could get an electric shock.
There is a risk of fatal injury.
R Never remove the headliner behind the
panorama roof.
R If the headliner is damaged, never touch the
electrical components behind it.
R Always have work on the MAGIC SKY CON-
TROL carried out at a qualified specialist
workshop. The high-voltage components of MAGIC SKY
CONTROL are protected behind the head-
liner.
The MAGIC SKY CONTROL voltage trans-
former is stamped with a high-voltage sym-
bol, warning you about the high voltage. The
electric cables of the high-voltage section are color orange.
Operating MAGIC SKY CONTROL X

Useful information
i This Operator's Manual describes all
models and all standard and optional equip- ment 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 Read the information on qualified special-
ist workshops (Y page 25). Overview of climate control systems
General notes
Observe the settings recommended on the
following pages. The windows could other-
wise 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 dehumidifi-
cation function
R switch on the defrost windshield function
briefly, if required
Climate control regulates the temperature
and air humidity in the vehicle interior. The air filter cleans the air, thus improving the inte-
rior climate.
The "Cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. Optimum climate control is only ach-
ieved with the side windows and roof closed.
The residual heat function can only be acti-
vated or deactivated with the ignition
switched off (Y page 139).
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. It also reduces gaseous pol-
lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle
interior. For this reason, you should alwaysobserve 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.
i It is possible that the blower may be acti-
vated automatically 60 minutes after the
SmartKey has been removed depending on various factors, e.g. the outside tempera-
ture. The vehicle is then ventilated for
30 minutes to dry the climate control sys-
tem. 132
