COMAND automatic climate control
COMAND automatic climate control
You can operate the automatic climate
control via COMAND or via the buttons on
the front and rear* automatic climate con-
trol panel (
page 469).
Some of the special climate control func-
tions can only be set via COMAND.The following automatic climate control
functions can be operated via COMAND:
iThe components and operating principles of
COMAND can be found on (
page 85).
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 253) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
Warning!G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and pages in the “Controls in detail” part
(
page 469) Otherwise the windows could
fog up, impairing visibility and endangering
you and others.

Central climate control menu via
COMAND
The central climate control menu is in the
center of the climate control settings.
When the automatic climate control is
switched on, you will see “on” in the cen-
tral menu. The following functions can only
be operated in the central climate control
menu via COMAND:
Select climate control settings
Cen-
tral menu.Switching cooling on or off
The cooling function, only operational
when the engine is running, cools the vehi-
cle interior down to the selected tempera-
ture. The cooling function also
dehumidifies the air in the vehicle interior,
thus preventing the windows from fogging
up.The “AC
OFF” function is used to permanent-
ly switch off the cooling function of the au-
tomatic climate control system.

iCondensation may drip out from underneath
the vehicle. This is normal and not an indication
of a malfunction.
Warning!G
If you turn off the cooling function, 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.

“Mono” is used to adjust the climate zones
for the entire vehicle at the same time.
When the “Mono” function is switched on
and you change the climate on the driver’s
side, these changes will be carried out in
the same manner for all climate zones.

switched off when you:

change an automatic climate control
setting for the front passenger’s side
using COMAND

operate a button from the automatic
climate control for the front passen-
ger’s side

operate one of the buttons for the rear
climate control system
Adjusting footwell temperature
The “Footwell Temperature” function is
used to adjust the temperature difference
between the footwell and the rest of the
passenger compartment.
The higher the selected value, the higher
the temperature in the footwell will be.
Select climate control settings
Cen-
tral climate control menu.
!If the air conditioning cannot be turned on
again, this indicates that the air conditioning is
losing refrigerant. The compressor has turned it-
self off.
Have the air conditioning checked at the nearest
authorized Mercedes-Benz Center.
iIn automatic mode, this setting optimizes
the footwell temperature when outside tempera-
tures are low.

iIn automatic mode, this setting optimizes
the air flow when outside temperatures are high.
iWhen the interior ambient temperature of
the vehicle is very hot and the automatic climate
control is cooling the interior, the setting for air
flow is temporarily overridden.


394 Controls in detail
Driving and parking
The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle in a safe location as
soon as possible and turn off the en-
gine. Allow engine and coolant to cool
off.
Check the coolant level and add cool-
ant if necessary (
page 547).In case of accident
If the vehicle is leaking gasoline:
Do not start the engine under any cir-
cumstances.
Move away from vehicle.
Notify local fire and/or police authori-
ties.
If the extent of the damage cannot be de-
termined:
Notify an authorized Mercedes-Benz
Center.
If no damage can be determined on the

major assemblies

fuel system

engine mount:
Start the engine in the usual manner.
Parking
iExcessive coolant temperatures trigger a
warning message in the multifunction display
(
page 646).
Warning!G
With the engine not running, there is no
power assistance for the brake and the
steering systems. In this case, it is impor-
tant to keep in mind that a considerably
higher degree of effort is necessary to brake
and steer the vehicle.
Warning!G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off
the engine and leaving the vehicle always:

Keep right foot on brake pedal.

Engage electronic parking brake.

470 Controls in detail
Automatic climate control
The 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 471). Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.The following automatic climate control
functions can be operated via COMAND:
iIf 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 469)

Temperature: 72°F (22°C) (page 472)

Footwell temperature: 0 (page 255)

Air flow: focused (page 256)
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 251). Otherwise
the windows could fog up, impairing visibili-
ty and endangering you and others.
iSevere conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (
page 385). The automatic climate con-
trol 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.
Do not obstruct air volume by placing objects on
the air volume-through exhaust slots below the
rear window.
