If the system detects an obstacle in this

illuminate and you hear a warning signal. If
the obstacle is closer than the minimum

Visual signals indicate to the driver the rel-

During parking maneuvers, pay special at-

posts, or trailer hitches etc.). The Parktronic sys-
tem will not detect such objects at close range
and damage to your vehicle or the object may
result.
Ultrasonic signals from outside sources (e.g.

492 Controls in detailAutomatic climate controlThe automatic climate control is operation-
al whenever the engine is running. You can
operate the climate control system in ei-
ther the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
It can only function optimally when you are
driving with the windows and the tilt/slid-
ing sunroof closed.
It is possible to completely deactivate the
climate control system (
page 493). Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.
i
If you have the air distribution and air vol-
ume automatically controlled, you can adjust the
temperature, footwell temperature and air flow.
The following basic settings are recommended:
Automatic air distribution control
(page 491)
Temperature: 72°F (22°C) (
page 494)
Footwell temperature: 0 (
page 274)
Air flow: focused (
page 275)
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and in the “COMAND automatic climate
control” section (
page 269). Otherwise
the windows could fog up, impairing visibili-
ty and endangering you and others.
Warning!
G
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.i
If the vehicle interior is hot, ventilate the in-
terior before driving off, see “Summer opening
feature” (
page 404). The automatic climate
control will then adjust the interior temperature
to the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow, leaves, sticks, and any other
debris.

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;.

Never operate the side windows and the

of anyone being harmed by the closing pro-
cedure.
When using the air recirculation mode with
convenience closing feature, should the up-
ward movement of a window be blocked by
some obstruction including but not limited
to arms, hands, fingers, etc., the automatic
reversal feature will not operate.
In the event that the procedure causes po-
tential danger, the closing of the side win-
dows can be immediately halted by pressing

the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
