heating MERCEDES-BENZ CL COUPE 2009 Owner's Manual

i
The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the settings recommended on the
following pages. Otherwise, the windows
could mist up. This may obstruct your view of
the traffic situation and, as a result, you may
cause an accident. Overview of air-conditioning system functions

endanger you and others.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.

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.

Risk of injury
Make sure that nobody can become trapped
between the side window and the door frame
as the side windows are opened and closed.

of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set.
i The blower will run at a low speed regard-
less of the airflow setting.

Switching the auxiliary heating/ven-
tilation* on/off
Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
i Switch the auxiliary heating on regularly
once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated using the vehicle's
fuel. For this reason, the tank content must
be at least at reserve fuel level to ensure that
the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. Before activating X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the rocker switch on the centre console.
You can use COMAND (Y page 172) or the
remote control to specify up to three depar-
ture times, one of which may be preselected.
Switching the auxiliary heating/venti-
lation on/off using the centre console

Switching the auxiliary heating/venti-

You may use two additional remote controls
for your vehicle. For further information, con-
sult a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
upwards when you press one of the but-
tons.

when the batteries in the remote control
are low. Replace the remote control bat-
