i If you have the air distribution and air
volume automatically controlled, you can
adjust the temperature, footwell
temperature and air flow. The following
basic settings are recommended:
R Automatic air distribution control
( Y page 366)
R Temperature: 72‡ (22†) ( Y page 367)
R Footwell temperature: 0 ( Y page 214)
R Air flow: focused ( Y page 215)
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, the tilt/sliding
sunroof or tilt/sliding panel 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.
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages and
in the “COMAND automatic climate control”
section. 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.
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, see “Summer
opening feature” (Y page 309). The climate
control will then adjust the interior
temperature to the set value much faster.
The following climate control functions can
be operated via COMAND:
R Temperature ( Y page 211)
R Air distribution ( Y page 212)
R Air volume ( Y page 212)
R Switching off cooling ( 0055) (Y page 213)

Maximum cooling MAX COOL
MAX COOL is only available in U.S. vehicles.
MAX COOL is only operational when the
engine is running.
If 005A is selected on both the left and right
side and there is a high demand for cooling,
the display MAXCOOL appears in the COMAND
display.
This provides the fastest possible cooling of
the vehicle interior (when windows and tilt/
sliding sunroof or tilt/sliding panel are
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!

endangering you and others. If the windows
begin to fog on the inside, switching off the
air recirculation mode immediately should

Power tilt/sliding sunroof
Opening and closing
GObserve Safety notes, see page 56.GWarning!
When opening or closing the tilt/sliding
sunroof, make sure there is no danger of
anyone being harmed by the opening/closing
procedure.
The tilt/sliding sunroof is equipped with the
express operation and automatic reversal
function. If the movement of the tilt/sliding
sunroof is blocked during the closing
procedure, the tilt/sliding sunroof will stop
and open slightly.
The tilt/sliding sunroof operates differently
when the sunroof switch is pressed and held.
See the “Closing when the tilt/sliding sunroof
is blocked” section for details.
The opening/closing procedure of the tilt/
sliding sunroof can be immediately halted by
releasing the sunroof switch or, if the sunroof
switch was moved past the resistance point
and released, by moving the sunroof switch in
any direction.
GWarning!
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury for
occupants wearing their seat belts properly as
entire body parts or portions of them may
protrude from the passenger compartment.
! To avoid damaging the seals, do not
transport any objects with sharp edges
which can stick out of the tilt/sliding
sunroof.
Do not open the tilt/sliding sunroof if there
is snow or ice on the roof, as this could
result in malfunctions.
If you cannot open or close the tilt/sliding
sunroof due to a malfunction contact
Roadside Assistance or an authorized
Mercedes-Benz Center.
! Please keep in mind that weather
conditions can sometimes change rapidly.
Make sure to close the tilt/sliding sunroof
when leaving the vehicle. If water enters
the vehicle interior, vehicle electronics
could be damaged which is not covered by
the Mercedes-Benz Limited Warranty.
i You can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO function, see “Summer
opening feature” ( Y page 309) and
“Convenience closing feature”
( Y page 309).
i After switching off the ignition or
removing the SmartKey from the starter
switch, you can operate the tilt/sliding
sunroof until you open the driver’s or front
passenger door. If no door was opened you
can operate the tilt/sliding sunroof for up
to 5 minutes.Power tilt/sliding sunroof373Controls in detail221_AKB; 6; 20, en-USd2ugruen,Version: 2.11.8.12009-09-24T13:28:17+02:00 - Seite 373Z

instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.
Do not exceed the maximum roof load of
220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the

braking, or sudden maneuvers, they could be
thrown around inside the vehicle and cause
injury to vehicle occupants.
Parcel nets cannot protect transported goods
in the event of an accident.
Parcel nets are located in the front passenger
footwell and on each side of the left and right
trunk side walls.
