Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle amaximum of
two times, drive for alonger distance.
Switch the auxiliary heating on regularly once a
month for aboutt en minutes.
The auxiliary heating heats the air in the vehicle interior to the set temperature. This occurs with-out using the heat of the running engine. The
auxiliary heating is operated directly 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 or auxiliary ventilation
automaticallya djusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automaticallya fter 50 minutes.
This time limit can be altered. To do this, visit a
qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to atemperature lower than
the outside temperature.

Turn the key to position 2in the ignition lock
(Y page 145).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also
be switched on if the manuallys et climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
R using the rocker switch on the centrec onsole
(Y page 139)
R using the remote control (Y page 140)The remote control can be used to set up to
