Interior lamps Reading lampsThe interior lamps operate automati-
cally.Switching interior lamps on
and offPress the button (arrow).
If you want the interior lamps to remain
off at all times, press and hold the but-
ton for approximately 3 seconds.
Press the button briefly to revert to
normal operation.
The luggage compartment lamp in the
sport wagon functions in the same

Footwell lamps The footwell lamps operate in the same
way as the interior lamps.
The reading lamps are located in the
front near the interior lamp. There are
also reading lamps in the rear. They can
be switched on and off with the switch
(arrow) adjacent to each lamp.
In order to conserve the battery,
all of the lamps in the vehicle
are switched off automatically approx.
15 minutes after the ignition key is
turned to position 0.<

Automatic climate control
If the windows should fog over in
the recirculated air mode, switch
the recirculated air mode off and in-
crease the air supply as required.<
Rear window defroster
When the rear window de-
froster is activated, the indica-
tor lamp comes on. The rear window
defroster switches off automatically.
Residual heat mode
The heat which is stored in
the engine is utilized for
heating the interior when the engine has
been switched off (while waiting at a
railroad crossing, for instance). In igni-
tion key position 1, you can alter the
settings of the automatic climate con-
trol. In ignition key position 0, the sys-
tem automatically directs heated air to
the windshield, side windows and foot-
wells.
This function may be activated
when the outside temperature is
below approx. 597 (156), the engine
is at operating temperature, and the
battery is adequately charged.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to select the opti-
mum airflow rates and directions for
your personal requirements:
Use rotary dial 1 to open and close the
airflow through an infinitely-variable
range. You can also use the levers 2 to
change the direction of the airflow.
Set the outlets so that the air flows past
you and does not flow directly on you.
Rotary dial 3 allows you to temper the
air flow from these outlets by adding
heat or cooling as desired:
Turn toward blue Ð colder
Turn toward red Ð warmer390de051
Rear passenger area ventilationRotary dial 1 opens the outlets in an in-
finitely-variable range. You can vary the
temperature of the air as it flows out us-
ing rotary dial 3 in the same manner as
for the front rotary dial.
You can change the direction of the air
flow with levers 2.390de354

Microfilter, activated-charcoal
filterThe microfilter removes dust and pollen
from the incoming air. The activated-
charcoal filter provides additional
protection by filtering gaseous pollut-
ants from the outside air. Your BMW
center replaces this combined filter as a
standard part of your scheduled main-
tenance. A substantial reduction in air
flow indicates that the filter must be
replaced before scheduled mainte-
nance.The seat cushion and backrest can
be heated with the ignition key in posi-
tion 2.
You can call up different heating modes
by repeatedly pressing the keys.
The highest heating mode is on when
the three indicator lamps are lit; one
lamp is lit for lowest heating. Tempera-
ture regulation in each mode is with a
thermostat.
You can also switch the higher heating
modes off directly:
Press the key and hold it slightly longer.

To activate and cancel the steering
wheel heater, press the button (arrow)
with the ignition key in position 2.
The lamp within the button lights up
when the steering wheel heater is in op-
eration.
If you have a multifunction steering
wheel without steering wheel heating,
the button for the recirculated-air mode
is in this location (refer to page 25).390de630

To operate, press the key briefly with
the ignition key in position 1 or 2.Roller sun blinds for rear side
windows

Use the strap to extract the blinds, then
hook them in the attachment provided.390de357
This system allows you to ventilate the
interior and lower its temperature, using
the blower of the automatic climate
control.
The independent ventilation system is
operated via the multi-information dis-
play MID or the onboard computer. Re-
fer to the separate Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also turn it on and
off directly. Since the system uses a
substantial amount of electrical current,
you should not activate it twice in suc-
cession without allowing the battery to
be recharged in normal operation
between use.When a preselected activation time is
set, the independent ventilation system
is operational at outside temperatures
above 607 (166), or by direct switch
activation. It cannot be switched on
when the vehicle is moving.
The air emerges via the vent outlets for
the upper body. Therefore, the vents
must be open for the system to operate.

The conceptThe BMW Universal Transmitter re-
places up to three hand-held transmit-
ters that control different devices such
as a garage door opener, alarm sys-
tems or a door locking system. The
BMW Universal Transmitter recognizes
and "learns" the transmitted signal from
each of the original hand-held transmit-
ters.
The signal of an original hand-held
transmitter can be programmed to one
of three channel keys. Following that,
each of the devices can be operated
with the channel key that you have pro-
grammed for it. A transmission of the
signal is indicated by the indicator lamp.
Before you sell your vehicle, the pro-
grammed channel keys should be de-
leted. Refer to page 107 for the de-
scription of this process.
To prevent potential injuries or
damage: During the programming
operation and before every remote trig-
gering of a programmed device using
the BMW Universal Transmitter, be sure
that there are no persons, animals or
objects within the range of movement
of the respective device. Read and
comply with the safety instructions for
the original hand-held transmitter
also.<
To Canadian residents:
During programming, your hand-
held transmitter may automatically stop
transmitting after two seconds. This
may not be long enough to program the
BMW Universal Transmitter. If you are
programming from one of these hand-
held transmitters, the Universal Trans-
mitter's lamp may begin to flash in a se-
ries of double flashes. If this occurs,
continue to hold the button on the Uni-
versal Transmitter while you reactivate
your hand-held transmitter. You may
have to repeat this function several
times while programming.<
Before programming, read the
"User's information" section on
page 107.<
The original hand-held transmitter
If this symbol is depicted on the
packaging or in the user's in-
structions for the original hand-
held transmitter, it may be assumed
that this original hand-held transmitter
is compatible with the BMW Universal
Transmitter.
Checking for the change codeIn order to determine whether the origi-
nal hand-held transmitter is equipped
with a change code system, you may
either refer to the instructions for the
original hand-held transmitter or pro-
gram a channel key as described in the
left column on page 106 under "Pro-
gramming."
Following that, press and hold the pro-
grammed channel key of the BMW Uni-
versal Transmitter. If the indicator lamp
of the BMW Universal Transmitter
flashes rapidly for two seconds and
then stays on continuously, the original
hand-held transmitter is equipped with
a change code system. If the change
code system is available, program the
channel keys as described in the right-
hand column on page 106 under "Pro-
gramming a hand-held transmitter with
change code."
If you have additional questions,
please consult your BMW center
or call 1-800-355-3515.<
