Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhalin gthese
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 stations or when your vehi-
cle is being refuelled .You must therefore
switc hoff the auxiliary heating at filling sta-
tions.
! Operatin gthe auxiliary heating/ ventila-
tion draws on the vehicl ebattery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for alonger
distance.
i Switch on the auxiliary heatin gregularly,
e.g. for about ten minutes ever ymonth.
The auxiliary heatin gheats the air in the vehi-
cle interior to the set temperature without
using the heat of the runnin gengine .The aux-
iliary heating is operated directly usin gthe
vehicle' sfuel. 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 when the
engine is switched off. The auxiliary ventila-
tion switches off when you turn the key to key
position 2.
The auxiliary heating switches off automati-
cally after 30 minutes. This time limit can be
altered. To do this, visit aqualified specialist
workshop, e.g. aMercedes-Benz Service
Centre.
You can notu se the auxiliary ven tilation to
cool the vehicle interior to atemperature
lower than the outside temperature.
Before switching on 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 climate control 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 deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 250).130

sult aqualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. The remote control has
amaximum 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 transmittin gfrom an enclose dspace
