General notes
The wind screen offers protection from the
wind when driving with the roof down.
GWARNING
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.
GWARNING
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.
GWARNING
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.

MAGIC SKY CONTROL
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
automatically when you turn the SmartKey
to position 0 in the ignition lock or remove
the SmartKey.
88RoofOpening/closing

Risk of electric 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.
GDANGER
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.
Operating MAGIC SKY CONTROL
XTurn the SmartKey to position 1 or 2 in the
ignition lock.

GWARNING
Repeatedly setting the seat heating to level
3 may result in excessive seat temperatures.
The health of passengers that have limited
temperature sensitivity or a limited ability to
react to excessively high temperatures may
be affected or they may even suffer burn-like
injuries. Therefore, do not use seat heating
level 3 repeatedly.
The three red indicator lamps in the button
indicate the heating level you have selected.
i If the battery voltage is too low, the seat
heating may switch off.

1 or 2 in the ignition lock.XTo switch on: press button : repeatedly
until the desired heating level is set.XTo switch off: press button : repeatedly
until all the indicator lamps go out.Seats95Seats, steering wheel and mirrorsZ

Problems with the seat heating
The seat heating has switched itself off
prematurely. The vehicle's electrical system
voltage is too low because too many electrical
consumers are switched on.
XSwitch off electrical consumers that you do
not need, such as the rear window
defroster or interior lighting.XOnce the battery is sufficiently charged,
switch on the seat heating again.
AIRSCARF
Switching on/off
GWARNING
Very hot air can flow out of the AIRSCARF
vents in the head restraints when AIRSCARF
is in operation. This can cause burns on
unprotected skin near the AIRSCARF vents.
Lower the heating output in good time, when
necessary.
The AIRSCARF function warms the head and
neck area of vehicle occupants with warm air.
The warm air flows out of the holes in the head
restraints.
The three red indicator lamps in the button
indicate the heating level you have selected.
XMake sure that the SmartKey is in
position 2 in the ignition lock.XTo activate: press button :.
Three red indicator lamps in the button light

phase of seven seconds.XPress button : repeatedly until the
desired heating level is set.XTo switch off: press button : repeatedly
until all the indicator lamps go out.
i The blower continues running for seven
seconds to cool down the heating
elements.
i If the battery voltage is too low, AIRSCARF
may switch off.
Problems with AIRSCARF
AIRSCARF has switched off prematurely or
will not switch on. The vehicle's electrical
system voltage is too low because too many
electrical consumers are switched on.
XSwitch off electrical consumers which you
do not need, such as the rear window
defroster or interior lighting.XSwitch on AIRSCARF again.
Steering wheel

store the setting with the memory function
( Y page 100).
Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering column
will move upwards when the driver's door is
opened. This occurs irrespective of the
position of the SmartKey in the ignition lock.
This makes it easier to exit the vehicle and
rescue the occupants.
The crash-responsive EASY-EXIT feature is
only operational after an accident if the EASY-
