can also set the airflow and air distribution
of the automatic climate control to one of
three levels (FOCUS/MEDIUM/DIFFUSE).

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

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
limatecontrol system

You cannot use the auxiliary ventilation to
cool the vehicle interior to atemperature
lower than the outsid etemperature.
Befor eswitchin gon X

X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the climat econtrol is being
controlled manually. Optimum comfor tcan
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 deactivate dusing the remote control
or the button on the centr econsole.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 229).
