Maximum cooling MAXCOOL (USA only)
If U 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 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 in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
!
The rear window defroster uses a large
amount of power. To keep battery drain to a min-
imum, switch off the defroster as soon as the
rear window is clear.
i
The defroster is automatically deactivated
after some time of operation depending on the
outside temperature.
Warning!
G
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.i
If the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
i
Maximum cooling MAXCOOL is only avail-
able when the engine is running.Warning!
G
Fogged windows impair visibility, endanger-
ing 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 (
page 272) is activated, or
press button;.

G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an ob-
struction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by
pressing and holding button‹on the
SmartKey, by pressing and holding the sen-
sor surface (vehicles with KEYLESS-GO*) on
the outside door handle, the automatic re-
versal function will not operate.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
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.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.!
To avoid damaging the seals, do not trans-
port 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 sun-
roof due to a malfunction contact Roadside As-
sistance 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, vehi-
cle electronics could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.
i
When the tilt/sliding sunroof is open, reso-
nance noises may result in addition to the usual
wind noises. They are caused by minimal pres-
sure changes in the passenger compartment. To
reduce or eliminate these noises, change the po-
sition of the tilt/sliding sunroof or open a side
window slightly.
