COMAND automatic climate control
Introduction
iThe components and operating principles
of COMAND can be found on (Y page 76).
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages and
pages in the “Controls in detail” chapter.
Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
You can operate the climate control via
COMAND or via the buttons on the climate
control panel (Y page 363).
Some of the special climate control functions
can only be operated via COMAND.
The following climate control functions can
be operated via COMAND:
RTemperature (Y page 211)
RAir distribution (Y page 212)
RAir volume (Y page 212)
RSwitching off cooling (Æ)
(Y page 213)
RCentral climate control (Mono)
(Y page 214)
RFootwell temperature (Y page 214)
RAir flow from air vents (Y page 215)
RRear climate control (Y page 215)
The climate control menu is called up via the
climate control settings.

Central climate control menu via
COMAND
The central climate control menu is in the
center of the climate control settings. When
the climate control is activated, you will see
AC in the central menu. The following
functions can only be operated in the central
climate control menu via COMAND:
RDeactivating cooling (Æ) (Y page 213)

Activating/deactivating air
conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
iCondensation may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
GWarning!
If you deactivate the air conditioning, 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.
XSelect climate control settings Q Central
climate control menu.
XSelecting Æ: Slide ZVÆ or rotate
cVd.
XConfirming selection: Press W.
A checkmark appears when the cooling is
deactivated.
Æ appears in the central menu of the
climate control settings.

Adjusting air flow from air vents
iIn automatic mode, this setting optimizes
the air flow when outside temperatures are
high.
The Airflow setting defines air distribution
and air volume in automatic mode:
RFocused (default setting, increased air
flow)
RMedium (reduced air flow)
RDiffuse (minimal air flow)
iWhen the interior ambient temperature of
the vehicle is very hot and the climate
control is cooling the interior, the setting
for air flow is temporarily overridden.

rear climate control via COMAND and the
rocker switches on the control panel from the
front (Y page 363).

The electronic parking brake releases
automatically.
The red indicator lamp F (USA only)
or ! (Canada only) in the instrument
cluster goes out.
After a cold start, the automatic transmission
shifts at a higher engine speed. This allows
the catalytic converter to reach its operating
temperature earlier.
For more information on driving, see “Driving
instructions” ( Y page 434).
Problems while driving
The engine runs erratically and misfires
R An ignition cable may be damaged.
R The engine electronics may not be
operating properly.
R Unburned gasoline may have entered the
catalytic converter and damaged it.
XGive very little gas.XHave the problem checked at an authorized
Mercedes-Benz Center as soon as possible.
The coolant temperature is above
248‡ (120†)
The coolant is too hot and is no longer cooling
the engine.
XStop the vehicle in a safe location as soon
as possible.XTurn off the engine immediately.XAllow the engine and coolant to cool off.XCheck the coolant level and add coolant if
necessary ( Y page 408).In case of accident
If the vehicle is leaking fuel:
XDo not start the engine under any
circumstances.XExit the vehicle at a safe distance from the
roadway.XNotify local fire and/or police authorities.
If the extent of the damage cannot be
determined:
XContact an authorized Mercedes-Benz
Center or call Roadside Assistance.
If no damage on major assemblies, fuel
system, and engine mount can be
determined:
XStart the engine in the usual manner.
Parking
GWarning!
Do not park in areas where the hot exhaust
system could come into contact with
combustible materials. Combustible
materials such as grass, hay or leaves could
be ignited and cause a vehicle fire.
Unintended vehicle movement could cause
serious personal injury or damage to the
vehicle or the vehicle drivetrain. To reduce
such risks, always do the following before
turning off the engine and leaving the vehicle:
R Keep right foot on the brake pedal.
R Engage the electronic parking brake.
R Shift the automatic transmission into park
position P.
R Slowly release the brake pedal.
R When parked on an incline, always turn the
front wheels towards the road curb.
R Turn the SmartKey in the starter switch to
position 0 and remove the SmartKey from

control, lefti Set the temperature to 72‡ (22†).Notes on climate control system
i If you have the air distribution and air
volume automatically controlled, you can
adjust the temperature, footwell
temperature and air flow. The following
basic settings are recommended:
R Automatic air distribution control
( Y page 366)
R Temperature: 72‡ (22†) ( Y page 367)
R Footwell temperature: 0 ( Y page 214)
R Air flow: focused ( Y page 215)
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows, the tilt/sliding
sunroof or tilt/sliding panel closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
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.
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages and
in the “COMAND automatic climate control”
section. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
XKeep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” (Y page 309). The climate
control will then adjust the interior
temperature to the set value much faster.
The following climate control functions can
be operated via COMAND:
R Temperature ( Y page 211)
R Air distribution ( Y page 212)
R Air volume ( Y page 212)
R Switching off cooling ( Æ) (Y page 213)

Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, 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.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
The cooling function can be activated or
deactivated via COMAND ( Y page 213).
Automatic mode
When operating the climate control system in
automatic mode, the interior air temperature,
air volume and air distribution are adjusted
automatically.
