For draft-free ventilation, move the sliders
for the center air vents 4 and 7 to the middle
position.
Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents.
Always keep sufficient distance between un-
protected parts of the body and the air
vents. If necessary, use the air distribution
adjustment (
page 230) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.

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 or tilt/sliding panel*
are closed).
!
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.
