Auxiliary heater
*
Independent ventilation
*
If your car has an auxiliary fuel-burning
heater, it is also equipped with inde-
pendent ventilation control. Cars are
also supplied with independent ventila-
tion control only.
Both systems are operated via the
Multi-Information Display (MID) (see
page 88) or the on-board computer.
There is a separate Owner's Handbook
for the on-board computer.
Two different switch-on times can be
preselected, so that you can be sure
that the car's interior is warm when it is
next entered. Snow and ice are also
easier to remove from the windows.
The auxiliary heater runs for 30 minutes.
It can also be switched on and off
directly. Since its current consumption
is high, it should not be run twice in
succession unless there has in the
meantime been an opportunity to
recharge the car's battery by driving the
car.
The auxiliary fuel-burning heater can be
operated at outside temperatures
below 16
6
if the switch-on time is
preselected, or switched on directly at
any outside temperature. This only
applies when the car is driven,
however, until the engine has reached
its regular operating temperature.
The heated air is directed automatically
to the windscreen, side windows and
footwell; maximum heating output is
always used.
In ignition key position 1 you can adjust
the interior temperature, air supply and
air distribution.
The auxiliary heater continues to run for
a short period after it has been
switched off (indicator light out).
Even during the warm season of
the year the auxiliary heater
should be switched on directly about
once a month, then switched off again
after about 5 minutes.
<
Do not operate the auxiliary heater
in confined spaces (closed
rooms). Always switch off the auxiliary
heater before refuelling the car.

Ventilates the interior of the car and
lowers its temperature by means of the
(automatic) air conditioning blower.
The independent ventilation control is
operated via the Multi-Information
Display (MID) (see page 88) or the on-
board computer. There is a separate
Owner's Handbook for the on-board
computer.
Two different switch-on times can be
preselected; the ventilation system then
runs for 30 minutes. It can also be
switched on and off directly. Since its
current consumption is high, it should
not be run twice in succession unless
there has in the meantime been an
opportunity to recharge the car's
battery by driving the car.
Independent ventilation control can be
operated at any outside temperature
above 16
6
if the switch-on time is
preselected, or switched on directly at
any outside temperature, but not when
the car is being driven.
Air emerges from the variable-flow,
controlled-direction outlets for the
upper body zone on the fascia. These
outlets must therefore remain open if
the independent ventilation system is to
be used.
In ignition key position 1, the airflow
volume and air distribution are adjusted
in the same way as for auxiliary heating.
