FunctionRecommendation/Notes0077Air distribution, left0078Temperature
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 ( 0055) (Y page 213)
R Central climate control ( Mono)
( Y page 214)
R Footwell temperature ( Y page 214)
R Air flow from air vents ( Y page 215)
R Rear climate control ( Y page 215)

The climate control switches to the following
functions automatically:
R most efficient blower speed and heating

R air flows onto the windshield and the front
door windows
R the air conditioning compressor switches

approximately 41‡ (5†) for air-drying
Adjustments
You can adjust the air volume and the
temperature when the front defroster is
switched on. The air flow will remain on the
windshield and front door windows.

increase or decrease air volume to the
desired level.

Maximum cooling MAX COOL
MAX COOL is only available in U.S. vehicles.
MAX COOL is only operational when the
engine is running.
If 005A 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 through
a tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
GWarning!
Fogged windows impair visibility,
endangering 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

automatically at high outside
temperatures.
The indicator lamp in rocker switch 0074 is
not lit when the air recirculation mode is

A quantity of outside air is added when the
cooling demand is not at maximum.
If the air conditioning has been turned off
or the outside temperature is below 41‡
(5†), the air recirculation mode will not
switch on automatically.
XDeactivating: Press rocker switch 0074 up
or down.

i The manually selected air recirculation
mode is deactivated automatically:
R after 5 minutes if the outside
temperature is below approximately
41‡ (5†)
R after 5 minutes if the air conditioning is
turned off
R after 30 minutes if the outside
temperature is above approximately
41‡ (5†)
Residual heat and ventilation
With the engine turned off, it is possible to
continue to heat or ventilate the interior for
up to 30 minutes. This feature makes use of
the residual heat produced by the engine.
i If you switch on the residual heat function
when outside temperatures are high, only
the ventilation will be switched on.
i Regardless of the selected air volume, the
blower operates at low speed when
heating. In case of ventilation the blower
operates at higher speed.
i How long the system will provide heating
depends on the coolant temperature and
the selected temperature. The blower will
run at low speed regardless of the air
distribution control setting.XActivating: Switch off the ignition.XPress rocker switch 004D up or down.

R if the coolant temperature is too low
Rear window defroster
GWarning!
Any accumulation of snow and ice should be
removed from the rear window before driving.
Visibility could otherwise be impaired,
endangering you and others.
The rear window defroster uses a large
amount of power. To keep the battery drain
to a minimum, switch off the defroster as
soon as the rear window is clear. The
defroster is switched off automatically after
approximately 6 to 17 minutes of operation
depending on the outside temperature.

obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.
Power assistance
GWarning!
There is no power assistance for the steering
and the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion.
Brakes
Downhill grades
! When driving down long and steep
grades, relieve the load on the brakes by
shifting into a lower gear to use the
engine’s braking power. This helps prevent
overheating of the brakes and reduces
wear.
When using the engine’s braking power, a
drive wheel may not spin for an extended
period of time, e.g. on slippery road
surfaces. This may cause serious damage
to the drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Continuous or hard braking
GWarning!
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their
effectiveness. It may not be possible to stop
the vehicle in sufficient time to avoid an
accident.
After hard braking, it is advisable to drive on
for some time, rather than immediately park,
so that the air stream will cool down the
brakes faster.
Wet roadsGWarning!
After driving in heavy rain for some time
without applying the brakes or through water
deep enough to wet brake components, the
first braking action may be somewhat
reduced and increased pedal pressure may be
necessary to obtain expected brake effect.
Maintain a safe distance from vehicles in
front.
To help prevent brake disk corrosion after
driving on wet or salt-covered roads, it is
advisable to brake the vehicle with
considerable force prior to parking. The heat
generated serves to dry the brakes.
Salt-covered roads
GWarning!
A layer of salt on the brake discs and the brake
linings may cause a delay in the braking
effect, resulting in a significantly increased
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you are
driving on salt-covered roads, so that any
layer of salt that may have built up on the
brake discs and the brake linings is
