2012 MERCEDES-BENZ SL550 air condition

The vehicle chassis ride height is raised or
lowered according to the selected level
setting and to the vehicle speed. With
increasing speed, the ride height is reduced
by up to approximately 0.5 in (12 mm). With
decreasing speed, the ride height is again
raised to the selected vehicle level.
These height adjustments are so small that
you may not notice any change.
Setting the vehicle level
GWarning!
To help avoid personal injury, keep hands and
feet away from wheel housing area, and stay
away from under the vehicle when lowering
the vehicle chassis.
The following vehicle level settings can be
selected when the vehicle is stationary and
the engine is running:

The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.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 clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
The air conditioning will not engage (no
cooling) if the A/C mode ( Y page 150) is
deactivated.
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.XKeep the air intake grille in front of the
windshield free of snow and debris.
When the retractable hardtop is closed, do
not obstruct air flow by placing objects on the
air flow-through exhaust slots below the rear
window.
i If the vehicle interior is hot, ventilate the
interior before driving off. The climate
control will then adjust the interior
temperature to the set value much faster.
Deactivating the climate control
system
GWarning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time when the
retractable hardtop is closed. Otherwise the
windows could fog up, impairing visibility and
endangering you and others.

Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, 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.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
Deactivating
It is possible to deactivate the air
conditioning. The interior air will then no
longer be cooled or dehumidified.
XPress button Á.

Automatic mode
Air distribution and air volume can be
adjusted automatically by the climate control
system. You can also adjust the settings for
air distribution and air volume manually.
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
In automatic mode, cooling with
dehumidification is switched on. This function
can be switched off if necessary.
GWarning!
If you deactivate the air conditioning, 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.

Ventilated glove box
The glove box can be ventilated, for instance
to cool its contents, when the climate control
system is activated. The level of airflow to the
glove box depends on the airflow and air
distribution settings. The temperature of the
air is approximately the same as that of the
air flowing from the center air vents.
! Close the glove box air vent when heating
the vehicle interior. Activate the air
conditioning (cooling function) when the
outside temperature is high. Otherwise,
temperature-sensitive items stored in the
glove box could be damaged.
iYou should keep air vent ; closed when
outside temperatures are low.
XOpening the air vent: Make sure air

AIRSCARF vent
GWarning!
When switching on the AIRSCARF neck-level
heating, the air streaming from the openings
may be very hot. When in close proximity to
the openings, you could be seriously burned.
To help avoid serious personal injuries, switch
the AIRSCARF to a lower heating level.

MAX COOL is only operational when the
engine is running.
If the air distribution controls as well as the
air volume control are set to à and there
is a high need for cooling, MAX COOL is
activated. “MAX COOL” appears in
temperature controls C and H
(Y page 148).
This provides the fastest possible cooling of
the vehicle interior (when retractable hardtop
is closed).

Air recirculation mode
Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e. g. before driving through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
GWarning!
Fogged windows impair visibility,
endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should
clear interior window fogging. If interior
window fogging persists, make sure the air
conditioning is activated, or press button
¬.
XActivating: Press button g.
The indicator lamp in the button comes on.
iThe air recirculation mode is activated
automatically at high outside
temperatures.
The indicator lamp in button g is not lit
when the air recirculation mode is switched
on automatically.
A quantity of outside air is added after
approximately 30 minutes.
XDeactivating: Press button g again.
The indicator lamp in the button goes out.
iThe manually selected air recirculation
mode is deactivated automatically:
Rafter 5 minutes if the outside
temperature is below approximately
41‡ (5†)
Rafter 5 minutes if the air conditioning is
turned off
Rafter 30 minutes if the outside
temperature is above approximately
41‡ (5†)
Residual heat and ventilation
With the engine turned off, it is possible to
continue to heat or ventilate the interior for
up to 30 minutes. This feature makes use of
the residual heat produced by the engine.
iIf you switch on the residual heat function
when outside temperatures are high, only
the ventilation will be switched on.
iHow long the system will provide heating
depends on the coolant temperature and
the selected temperature. The blower will
run at low speed regardless of the air
distribution control setting.

Programming tips
If you are having difficulty programming the
integrated remote control, here are some
helpful tips:
R Check the frequency of hand-held remote
control A (typically located on the reverse
side of the remote). The integrated remote
control is compatible with radio-frequency
devices operating between 280-390 MHz.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
( ; , = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R If another hand-held remote control is
available for the same device, try the
programming steps again using that other
hand-held remote control. Make sure new
batteries are in the hand-held remote
control before beginning the procedure.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call
the Mercedes-Benz Customer Assistance
Center (USA only) at
1-800-FOR-MERCedes (1-800-367-6372),
or the HomeLink ®
