Adjusting air vents
GWarning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
XKeep the air intake grille in front of the
windshield free of snow, leaves, sticks, and
any other debris.
XAlways keep all air vents and grilles in the
passenger compartment free from
obstruction.
iFor draft-free ventilation, move the
adjustable center and side air vents to the
middle position.

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.

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

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
