If your car has an independent fuel-
burning heater, it is also equipped
with independent ventilation control.
However, independent ventilation con-
trol can be installed an its own.
Both systems are operated by the on-
board computer; see Page 60.
The independent heater's operating
period can be preselected so that the
car's interior is already warm when
the journey is due to start. Snow and
ice are also easier to remove from the
windows.
The independent heater runs for 30
minutes. Since its current consump-
tion is high, it should not be run twice
in succession unless there has in the
meantime been an opportunity to
recharge the car's batteries by a
period of driving reasonable speeds.
The independent heater can also be
switched on and off directly.
The independent heater can be run at
outside temperatures below 16
6 , but
not while the car is being driven.
The heated air is supplied automati-
cally to the car's defrosting and foot-
well outlets; the heater runs at
maximum output in all cases.
In ignition key position 1 you can vary
the interior temperature (at the tem-
perature selectors) and the air distri-
bution (by means of the pushbuttons).
After it has been switched off (LED off)
the independent heater continues to
run for a short period.
If the independent heater does not
start after a maximum of two
attempts, or switches itself off auto-
matically, consult BMW Service.
b
Even during the warm season of
the year the independent heater
should be run briefly about once a
month.
To do this if the temperature is above
16

:
d
Press the TEMP and TIMER but-
tons on the on-board computer at
the same time: the INV (inverted)
inscription will appear.

Switch the independent heater on
directly and switch off again after
about 5 minutes.
c
a
Never operate the independent
heater in an enclosed space. Always
switch off the independent heater
before refuelling the car.

This system supplies air to the interior
and lowers its temperature by means
of the automatic air conditioning fan.
The switch-on time can be prese-
lected; the ventilation then runs for
30 minutes. It can also be switched on
and off directly. Since its current con-
sumption is high, it should not be run
twice in succession unless there has
in the meantime been an opportunity
to recharge the car's batteries by a
period of driving reasonable speeds.
Independent ventilation control is
available at outside temperatures
above 16
6 , but not when the car is
being driven.
Air is driven to the grilles in the fascia
and doors. These grilles must there-
fore be opened before the independ-
ent ventilation control is switched on
or preselected.
