If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no long-
er be indicated by the system.Warning indicators
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle.
The warning indicator for the front area is
in the instrument cluster. The warning indi-
cator for the rear area is on the roof liner in
the rear.

During parking maneuvers, pay special at-
tention to objects located above or below the
height of the sensors (e.g. street curbs, painted
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 re-
sult.
Ultrasonic signals from outside sources (e.g.
truck air brakes, car wash, or jackhammers) may
impair the operation of the Parktronic system.

If yellow indicators 3 under the segments
are lit, Park Assist is ready to measure.The position of the gear selector lever de-
termines which warning indicators will be
activated.
As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the sev-
enth distance segment illuminates, you
have reached the minimum distance.i
Due to the sensors’ broad detection range,
it is possible that Park Assist also detects the fol-
lowing obstacles and issues a warning:


obstacles in the ground, e.g. sewer canal
covers, rails, bumps in the road or gutters


obstacles moving upward quickly, e.g. rolling
garage doors

While parking, pay particular attention to ob-

objects. You could otherwise damage the vehicle
or the objects.

502 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/panorama sunroof* closed.
It is possible to completely deactivate the
climate control system (
page 503). 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 501)


Temperature: 72°F (22°C) (
page 504)


Footwell temperature: 0 (
page 278)


Air flow: focused (
page 279)
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 273). 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 412). 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 or tilt/sliding panel*
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 276) is activated, or
press button;.

The indicator lamp on button, is not lit when
the air recirculation mode is automatically acti-

A quantity of outside air is added when the cool-
ing demand is not at maximum.
If the air conditioning has been turned off
(
page 276) or the outside temperature is be-
low 41°F (5°C), the air recirculation mode will
not switch on automatically.
i
The manually selected air recirculation
mode is deactivated automatically:


after 5 minutes if the outside temperature is
below approximately 41°F (5°C)


after 5 minutes if the air conditioning is
turned off


after 30 minutes if the outside temperature
is above approximately 41°F (5°C)
Warning!
G
Never operate the door windows and the
tilt/sliding sunroof or tilt/sliding panel* if
there is the possibility of anyone being
harmed by the closing procedure.
Vehicles with tilt/sliding sunroof:
In the event that the procedure causes po-
tential danger, the closing of the door win-
dows can be immediately halted by pressing
the respective window switch. The closing of
the tilt/sliding sunroof can be immediately
halted by moving the tilt/sliding sunroof
switch in the overhead control panel in any
direction.
