Switching cooling with air dehumidifi-
cation on/off Cooling is operational when the engine is run-
ning and cools according to the selected inte-
rior temperature for the vehicle. Cooling also
dehumidifies the air inside the vehicle and,
thereby, prevents the windows from misting
up. G
Risk of accident
If you deactivate the cooling function with air
dehumidification, the vehicle will not be
cooled in warm weather and the air will not be
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.

Information and warning display
:
Yellow indicator lamp/red warning lamp
When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow up to a speed
of 30 km/h. At speeds above 30 km/h, the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red.
The yellow indicator lamp goes out three sec-
onds after reverse gear is engaged. In this
event, Blind-Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, could cause an
accident and injure yourself and others. Collision warning If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the turn
signal, a double warning tone sounds. Red

:flashes. If the turn signal
remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There
are no further warning tones.

(Y page 226) and Blind Spot Assist
(Y page 224) are activated in the on-board
computer.

General notes
The automatic air conditioning controls the
temperature and the humidity of the vehicle
interior and filters out undesirable substan-
ces from the air.
The automatic air conditioning is only opera-
tional when the engine is running. 31
Optimum
operation is only achieved when you drive
with the side windows and sliding/tilting sun-
roof closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 201).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.
31 The "residual heat" function can only be switched on/off if the ignition is switched off. 262

Instructions and recommendations for
optimum air conditioning:
R activate the air conditioning using the
à rocker switch. The indicator lamp
in the Ãrocker switch comes on.
R set the temperature to 22 †.
R only use the "demisting" function briefly,
until the windscreen is clear again.
R only use the "air-recirculation" mode
briefly, e.g. if there are unpleasant out-
side odours or when in a tunnel. Other-
wise, the windows could mist up due to
a lack of fresh air.
R use the "residual heat" function if you
want to heat or ventilate the vehicle inte-
rior when the ignition is switched off. The
"residual heat" function can only be acti-
vated or deactivated with the ignition
switched off. Switching the air conditioning on/off
i When the air conditioning is switched off,
the air supply and air circulation are also
switched off. Only select this setting briefly,
otherwise the windows may mist up.
i Activate the air conditioning primarily
using the Ãrocker switch
(Y page 264).
X Turn the key to position 2in the ignition
lock.
X To activate: press theÇrocker switch
up or down.
The indicator lamp in the rocker switch
goes out. The previously selected settings
come into effect again.
X To deactivate: press theÇrocker
switch up or down.
The indicator lamp in the rocker switch
comes on. Switching cooling with air dehumidi-
fication on/off
The "cooling with air dehumidification" func-
tion is only available when the engine is run-
ning. The air inside the vehicle is cooled and
dehumidified according to the temperature
selected. G
Risk of accident
If the "cooling with air dehumidification" func-
tion is deactivated, the air inside the vehicle
will not be cooled (during warm weather) or
dehumidified. The windows could mist up
more quickly. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode.
You can activate or deactivate the "cooling
with air dehumidification" function via
COMAND (Y page 170). Controlling the air conditioning auto-
matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated.
X Turn the key to position 2in the ignition
lock.
X Set the desired temperature.
X To activate: press theÃrocker switch
up or down.
The indicator lamp in the Ãrocker
switch comes on. 264

Setting the stowage compartment air
vent The stowage compartment can be ventilated
when the automatic air-conditioning system
is activated, for instance to cool its contents.
The level of airflow depends on the airflow and
air distribution settings. The temperature of
the air is approximately the same as that of
the air flowing from the centre air vents.
! Close the stowage compartment air vent
when heating mode is activated and acti-
vate the "cooling with air dehumidification"
function if the outside temperature is high.
Otherwise, temperature-sensitive items
stored in the stowage compartment could
be damaged. X
To switch the ventilation on/off: push
rocker switch down ;or up :.
Setting the glove compartment air vent The glove compartment can be ventilated
when the automatic air-conditioning system
is activated, for instance to cool its contents.
The level of airflow depends on the airflow and
air distribution settings.
! At high outside temperatures, open the
air vent and activate the "cooling with air
dehumidification" function. Otherwise,
temperature-sensitive items stored in the
glove compartment could be damaged. X

from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly at low outside temperatures. Other-
wise, the windows could mist up, thus impair-
ing visibility and endangering yourself and
others. This may prevent you from observing
the traffic conditions, thereby causing an
accident.
