Only vehicles with auxiliary heating have this
function.
The
Aux.heating departure time function
allows you to select a stored departure time
or change the departure time for which the
vehicle with auxiliary heating is preheated.
The auxiliary heating timer function calcu-
lates the switch-on time according to the out-
side temperature so that the vehicle is pre-
heated by the departure time. When the
departure time is reached, the auxiliary heat-
ing continues to heat for a further five
minutes and then switches off. The auxiliary
heating adopts the temperature settings
selected for Thermatic 2-zone automatic cli-
mate control or Thermotronic luxury multi-
zone automatic climate control*.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console. G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary 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 sys-
tem, e.g. a garage. G
Risk of fire
When the auxiliary heating is in operation,
parts of the vehicle can become very hot.
Make sure that the exhaust system does
not under any circumstances come into con-
tact with highly flammable materials such as
dry grass or fuels. The highly flammable mate-
rial could otherwise ignite and set the vehicle
alight. Select your parking space accordingly.
Operating the auxiliary heating is therefore
prohibited at filling stations or when your vehi-
cle is being refuelled. Always switch off the
auxiliary heating at filling stations. On-board computer

Thermotronic multi-zone luxury automatic climate control*
Front control unit
Rear control panel* Thermotronic multi-zone luxury automatic
climate control combines an automatic heat-
ing and ventilation system with a cooling sys-
tem. The temperature and air distribution
can be adjusted separately for the driver's
and front-passenger side as well as for the
rear compartment. You can control the air-
flow separately for the front and rear com-
partments. General notes
Thermatic 2-zone automatic climate control/
Thermotronic luxury multi-zone automatic cli-
mate control* controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
Thermatic 2-zone automatic climate control/
Thermotronic luxury multi-zone automatic cli-
mate control* is only operational when the
engine is running. 25
Optimum operation is
only achieved when you drive with the side
windows and sliding/tilting sunroof* closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 87). This
will speed up the cooling process and the
desired vehicle interior temperature will be
reached more quickly. i
The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the recommended settings on the
following pages. Otherwise, the windows
could mist up. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
25 The "residual heat" function can only be switched on/off when the ignition is switched off. Air conditioning
