Switch the auxiliary heating on regularly – once
a month – for about ten minutes.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by the departure time. When the departure time is
reached, the auxiliary heating continues to heat for a further five minutes and then switches off.
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 fuel tank must
be at least Õfull to ensure that the auxiliary
heating functions.
The auxiliary heating/ventilation automatically
adjusts to changes in temperature and weather conditions. For this reason, the auxiliary 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 ventilation
switches off when you turn the key to key posi-
tion 2(Ypage 144).
The auxiliary heating switches off automatically
after 50 minutes.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 144).
X Set the desired temperature.
Auxiliary heating or ventilation can also be
switched on if the manually set climate control is
activated. Optimum comfort is attained by set-
ting the system to automatic mode. Set the tem-
perature to 22 †.
The auxiliary heating or auxiliary ventilation can be switched on/off using the button on the
centre console or the remote control.
The on-board computer can be used to specify
up to three departure times, one of which may
be preselected (Y page 230). Switching the auxiliary heating/venti-
lation on or off using the button on the
centre console General notes
The colours of the indicator lamps on button
:
signify the following:
R Blue: auxiliary ventilation activated
R Red: auxiliary heating activated
R Yellow: departure time preselected
(Y page 230)

Switching the auxiliary heating/venti-
lation on or off using the remote control General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for
your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,
ensure that the remote control for the auxiliary
heating is kept out of the reach of children.
The remote control has a range of approximately
300 metre s. Thisrange is reduced by:
R sources of radio interference
R solid objects between the remote control and
the vehicle 138
