Notes on climate control system
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 341)
R Temperature: 72‡ (22†) (Y page 341) R
Footwell temperature: 0 (Y page 197)
R Air flow: focused ( Y page 197)
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 tilt/sliding
sunroof closed. Climate control system

Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.
G
Warning!
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. G
Warning!
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.
X Keep 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 283). 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 194)
R Air distribution (Y page 195)
R Air volume ( Y page 195)
R Switching off cooling (Æ) (Y page 196)

G
Warning!
When the climate control system is
deactivated, the outside air supply and
circulation are also deactivated. Only choose
this setting for a short time. Otherwise the
windows could
fog up, impairing visibility and
endangering you and others.
X Deactivating: Press

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. G
Warning!
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. 340

The climate control system will
correspondingly adjust the interior air
temperature. Adjusting air vents
G
Warning!
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:
X Keep the air intake grille in front of the
windshield free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction. Climate control system

Observe Safety notes, see page 51. G
Warning!
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. G
Warning!
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

Warning!
Always fasten items being carried as securely

appropriate for the weight and size of the
load.
In an
accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The trunk is the preferred place to carry
objects. Do not place anything on the rear-
window shelf.
Never drive a vehicle with the trunk open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
