Multifunction steering wheel (MFL)There are two design versions, depend-
ing on the equipment installed in your
vehicle.
The controls integrated in the multi-
function steering wheel (MFL) are pro-
vided so that you can operate a number
of accessories quickly and without be-
ing distracted from traffic conditions.
You may operate:
>Selected functions of the radio, the
CD and cassette modes
>The recirculated air mode of the air
conditioner or
>the steering wheel heater
>The cruise control and
>selected cellular phone functions.
In order to operate a system via
the MFL, the corresponding
system controls must be switched on.<
The illustration shows the maximum
possible number of controls, corre-
sponding to a full range of optional
equipment. Refer to the individual
accessory manuals for more detailed
descriptions.

Mirrors
The mirror on the passenger's
side features a lens with a more
convex surface than the mirror installed
on the driver's side. When estimating
the distance between yourself and
other traffic, bear in mind that the ob-
jects reflected in the mirror are closer
than they appear. This means that esti-
mations of the distance to following
traffic should not be regarded as pre-
cise.<
Electric heatersBoth mirrors are heated automatically
with the ignition key in position 2.
Interior rearview mirrorTo reduce glare from vehicles behind
you after dark, tilt the mirror by moving
the small lever.Lighted vanity mirrorFold down the sun visor and slide the
cover panel to the side as required.
The mirror lamps operate in ignition key
positions 1 and 2.Sun visorsThese can be folded down toward the
windshield or swiveled out against the
side windows.390de030
Interior rearview mirror with
automatic dimming feature
*
By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
select "Reverse."
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.
For an explanation of the electro-chro-
mic technology used in this mirror, refer
to page 192.390de031

Automatic climate controlTips for pleasant drivingUse the automatic system, that is, press
AUTO button 4. Select an interior tem-
perature that is comfortable for you Ð
we recommend 727 (226). When the
outside temperature is above 417
(56), you can also use the air condi-
tioning system (12). This will dry the air
and prevent the window from fogging
(for example if people are wearing
damp clothes in the vehicle). Set the
outlets 2 so that the air flows past you
and is not directed straight at you. Set
the rotary dial between the outlets 2 for
the upper body to a central position.
This will provide cooler air, and help to
prevent fatigue during the journey.
Detailed setting options are described
for you in the following section.
You can make the settings of your
vehicle in such a manner that,
when you unlock the car with your indi-
vidualized remote control, your own
personalized setting for the automatic
climate control is initiated.<
Automatic air distribution
The AUTO program assumes
the adjustment of the air dis-
tribution and the air supply for you and
also adapts the temperature to external
influences (summer, winter) to meet
preferences you can specify. This pro-
gram maintains a comfortable in-car cli-
mate regardless of the season. Select
an interior temperature that is pleasant
for you Ð we recommend 727 (226).
The selected temperature and AUTO for
the air flow appear in the display 7. Re-
fer to the overview on page 98. Open
the ventilation outlets for the upper
body. Switch on the air conditioner in
warm weather. The maximum cooling
capacity is achieved when you set the
rotary dial 3 (refer to page 102) to cold.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
You can direct air to flow onto the win-
dows , toward the upper body ,
and into the footwell .
Temperature
You can make individual tem-
perature settings on the
driver's side or the front pas-
senger side. Your settings will be
shown in the display 9. The displayed
temperatures are reference values for
the interior temperature. We recom-
mend 727 (226) as a comfortable
setting, whether the air conditioner is
operating or not.When you start the ve-
hicle, the system ensures that the se-
lected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the sea-
son.
Set the rotary dial 3 (refer to "Draft-free
ventilation" on page 102) to a medium
position to provide somewhat cooler
air. This helps to promote driving with-
out fatigue. Make use of this means of
mixing air especially for making minor
adjustments for personal comfort.
You can set uncontrolled heater
output at up to 907 (326). Full
cooling output is available from the air
conditioner down to 607 (166).<

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.
390de356
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
