Air conditioning
175highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
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 using fuel directly
from the vehicle's fuel tank. For this reason,
the tank content 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.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating 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 air conditioning is being
controlled manually. Optimum comfort can
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 135).
