G
Risk of injury
Very hot or very cold air can flow from the
air vents. This could cause burns or frost-
bite to bare skin in the immediate vicinity
of the vents. Keep bare skin away from
these air outlets. If necessary, direct the
airflow away to a different area of the vehi-
cle interior.
Please observe the following notes to ensure
that the air can flow freely through the air
vents:
R keep the air inlet between the windscreen
and the bonnet free of deposits, such as ice
and snow, to guarantee the supply of fresh
air into the vehicle interior.
R never cover the vents or air inlet and outlet
grilles in the vehicle interior.
i Position the sliders for the centre air
vents in the central position to provide vir-
tually draught-free ventilation. Cont

Risk of accident
Clear all windows of ice or snow before set-
ting off. Impaired visibility could otherwise
endanger you and others.
i At very low temperatures, the rear win-
dow heating is only switched on once the
vehicle interior has warmed up.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off as soon as the window is clear, as it only
switches off automatically after several
minutes.

Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary
heating in confined spaces without an
extraction system, e.g. a garage. G

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).
