could mist up. This may obstruct your view of
the traffic situation and, as aresult ,you may
cause an accident.
THERMATIC/THERMOTRONIC automatic cli-
mate control controls the temperature and
the humidit yofthe vehicle interior and filters
out undesirable substances fro mthe air.
THERMATIC/THERMOTRONIC automatic cli-
mate control is only operational when the
engine is running. 12
i Ventilate the vehicle for abrief period
during warm weather, e.g. using the con-
venience opening feature (Y page 83). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. Aclogged 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 Servic
eBooklet .Asit
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.
i It is possible that the residualh eat func-
tion may be activated automaticallyanh our
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system.

optimally.
R Activate climate control using the Ãand

can also set the airflow and air distribution
of the automatic climate control to one of
three levels (FOCUS/MEDIUM/DIFFUSE).
You can set the desired level using button
G.T he MEDIUM level is recommended.
R Set the temperature to 22 †.
R Only use the demisting function briefly until
the windscreen is clear again.
R Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odours or
when in atunnel. The windows could oth-
erwise mist up, as in air-recirculation mode,
no fresh air is drawn into the vehicle.
R Use the ZONE function to adopt the tem-
perature settings on the driver's side for
the front-passenger side and the rear com-
partment as well. The indicator lamp above
the á button goes out.
R Use the residual heat function if you want
to heat or ventilate the vehicle interior
when the ignition is switched off. The resid-
ual heat function can only be activated or
deactivated with the ignition switched off. Operating the climate control system
Switching climate control on/off
Important information i
When climate control is switched off, the

Important information The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted.
G
WARNING
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 THERMOTRONIC is in cool-
ing mode. This is normal and not asign that

It is possible to make use of the residual heat
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.
Coupé: the residual heat function only works
optimally when the side window sand pano-
rama sliding sunroo fare closed.
Cabriolet: the residualh eatfunction only
work soptimally when th esoftt op is closed.
i The blower will run at alow speed regard-
less of the airflow setting.
i If you activate the residual heat function
at high temperatures, only the ventilation
will be activated. The blower runs at
medium speed.
i It is possible that the residual heat func-
tion may be activated automatically an hour
after the key is removed. The vehicle is then
ventilated for 30 minutes to dry the air-
conditioning system.
X Turn the key to position 0in the ignition
lock or remove it.
X To activate: press theÌbutton.

cally:
R after about 30 minutes

R if the battery voltage drops
R if the coolant temperature is too low Auxiliary heating
Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefor eswitch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. agarage. G
WARNING
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 station sorwhen your vehi-
cle is being refuelled. You must therefore
switch off the auxiliary heating at filling sta-
tions.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for alonger
distance.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month.
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 directly using the
vehicle's fuel. For this reason, the tank con-
tent 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.
The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. To do this, visit aqualified specialist
workshop, e.g. aMercedes-BenzS ervice
Centre. Operating thec
