Important safety notesGWARNING
Before operating the retractable hardtop
(vario-roof), make sure there is no danger of
anyone being injured by the moving parts
(retractable hardtop, roof frame, and trunk
lid).
Hands must never be placed near the roof
frame, upper windshield area, hardtop, shelf
behind roll bars, or trunk lid while the
retractable hardtop is being raised or
lowered. Serious personal injury may occur.
If potential danger exists, release the
retractable hardtop switch or the % or
& button on the SmartKey. This
immediately interrupts the raising or lowering
procedure. You can then operate the
retractable hardtop switch or press the
% or & button on the SmartKey to raise
or lower the retractable hardtop away from
the danger zone.

Locking the roof again
GWARNING
Stop the vehicle in a safe location or as soon
as it is safe to do so and lock the retractable
hardtop before continuing to drive. You could
otherwise endanger yourself and others.
The roof is not locked when:
R the K symbol and the Vario-Roof in

General notes
The trunk partition can be used to cover
luggage and loads in the trunk.
! To avoid damaging the roof or luggage
when folding back the roof, you should:
R only load the trunk to below the trunk
partition
R not place any objects on or in front of the
trunk partition
R not place any objects on the cover
behind the roll bars
R not allow the cargo to push the trunk
partition upwards

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
up. The blower starts up after a preheating
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
Important safety notes
GWARNING
Do not adjust the steering wheel while driving.
Adjusting the steering wheel while driving
could cause the driver to lose control of the
vehicle.
The electrical steering wheel adjustment
feature can be operated at any time.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child's unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.

if the rear window defroster is switched on
and the outside temperature is low.XMake sure that the SmartKey is in position
1 or 2 in the ignition lock.XPress button ; for the right-hand exterior
mirror or button : for the left-hand
exterior mirror.XPress adjustment button = up, down, or

conditions.
Folding the exterior mirrors in or out
electrically
XMake sure that the SmartKey is in position
1 or 2 in the ignition lock.XBriefly press button :.
Both exterior mirrors fold in or out.
i Make sure that the exterior mirrors are
always folded out fully while driving. They
could otherwise vibrate.
Folding the exterior mirrors in or out
automatically
If the "Fold in mirrors when locking" function
is activated in the on-board computer
( Y page 195):
R the exterior mirrors fold in automatically as
soon as you lock the vehicle from the
outside.
R the exterior mirrors fold out again
automatically as soon as you unlock the
vehicle and then open the driver's or front-
passenger door.
i If the exterior mirrors have been folded in
manually, they do not fold out.
Exterior mirror out of position
If an exterior mirror has been pushed out of
position, proceed as follows:
XVehicles without electrically folding
exterior mirrors: move the exterior mirror
into the correct position manually.XVehicles with electrically folding
exterior mirrors: press the mirror-folding
button ( Y page 99) repeatedly until you
hear the mirror engage in position.
The mirror housing is engaged again and
you can adjust the exterior mirrors as usual
( Y page 98).
Automatic anti-glare mirrors
GWARNING
If incident light from headlamps is prevented
from striking the sensor in the rear-view
mirror, for instance, by luggage piled too high
in the vehicle, the mirror's automatic anti-
glare function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
glare mode if the ignition is switched on and

Overview of climate control systems
Important safety notes
GWARNING
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
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-
Benz Center as soon as possible.
GWARNING
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. 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 Maintenance Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Maintenance
Booklet.7 The residual heat function can only be activated/deactivated when the ignition is switched off.116Overview of climate control systemsClimate control

system
Below, you can find a number of notes and
recommendations to help you use the air-
conditioning system optimally.
R Switch on climate control using the ¿
button. The indicator lamp in the ¿
button lights up.
R Set the temperature to 72 ‡ (22 †).
R Recommendation for air distribution in
winter: set the O and ¯ settings.
Recommendation for air distribution in
summer: set the P setting.
R Only use the "defrosting" function briefly
until the windshield is clear again.
R Only use "air-recirculation" mode briefly,
e.g. if there are unpleasant outside odors
or when in a tunnel. The windows could
otherwise fog up as in air-recirculation
mode no fresh air is drawn into the vehicle.118Overview of climate control systemsClimate control
