Condensation forms during opera-
tion of the air conditioning system,
which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Outside air/Automatic
recirculated-air control (AUC)/
Recirculated air
You can respond to unpleasant
external odors or pollutants by
temporarily stopping the flow of outside
air. The system then recirculates the air
currently within the vehicle.
Press the button repeatedly to select
one of three different operating modes.
>Indicator lamps off: outside airflow is
on
>Left indicator lamp on – AUC mode:
the system recognizes pollutants in
the outside air and blocks the flow of
air when necessary. The system then
recirculates the air currently within
the vehicle. Depending on the air
quality, the automatic system then
switches back and forth between
outside air supply and recirculation of
the air within the vehicle
>Right indicator lamp on: the flow of
external air into the vehicle is perma-
nently blocked. The system then
recirculates the air currently within
the vehicle.
If the windows should fog over in
the recirculated-air mode, switch
this mode off and increase the air sup-
ply as required. When the rear window defroster
is activated, the indicator lamp
comes on. The rear window defroster
switches off automatically.
You can have your vehicle pro-
grammed in such a way that the
rear window defroster switches on
automatically. This occurs within 5 min-
utes after starting the engine when out-
side temperatures are below approx.
397/+46.<
Draft-free ventilationYou can adjust the blower controls for
the upper body area to obtain the opti-
mum airflow rates and directions for
your personal requirements:
1Rotary dials for infinitely variable
opening and closing of the vent out-
lets
2Levers for airflow direction
3Rotary dial allows you to control the
temperature of the airflow from these
outlets as desired

Microfilter/activated-charcoal
filterThe built-in microfilter removes dust
and pollen from the incoming air. The
activated-charcoal filter provides addi-
tional protection by filtering gaseous
pollutants from the outside air. Your
BMW center replaces this combined fil-
ter as a standard part of your scheduled
maintenance. A substantial reduction in
airflow indicates that the filter needs to
be replaced before scheduled mainte-
nance.
Roller sun blind*To actuate, press the button briefly with
the ignition key in position 1 or higher.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. The arrangement may vary
depending on the equipment actually
installed.

Premium sound system*Harman Kardon premium sound
systemPress the button to activate and deacti-
vate the acoustic enhancement.
The system creates the acoustic
impression of a much larger passenger
compartment accompanied by
improved stereophonic sound at all
seating positions.
The system responds to poor reception
conditions by repeatedly alternating
between the stereo and monophonic
modes. You should then switch the sys-
tem off.

compartment comes on.To closeFold the cover up.
To prevent injury in the event of an
accident, close the glove com-
partment immediately after use. master key will also be required to
unlock the glove compartment.

Ski bag*The ski bag allows the safe and clean
transport of up to 4 pairs of standard
skis or up to two snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis up to 6 ft 10 in / 2.10 m long.
Because of the tapered shape of the
bag, only two pairs of skis longer than
6 ft 10 in / 2.10 m can be carried.
LoadingVehicles without through-loading sys-
tem:
1. Fold the center armrest outward.
Loosen the trim from the upper
Velcro® fastener and place it on the
armrest
2. Press the button – see arrow 1, from
inside the passenger compartment:
this releases the cover panel in the
luggage compartment
3. Press the detent levers inward – see
arrows 2 – and fold the cover to the
front
4. Extend the ski bag between the front
seats. The zipper provides conve-
nient access to stored items. It may
be opened to allow the ski bag to dry
5. Use the magnetic retainers to attach
the cover panel to the upper surface
– metal surface below rear tray – of
the luggage compartment.
To store the ski bag, perform the above
steps in reverse sequence.

Determining the maximum load1. Locate the following statement on
your vehicle's placard*:
The combined weight of occu-
pants and cargo should never
exceed XXX kg or YYY lbs., as this
could otherwise result in damage to the
vehicle or unstable driving conditions.<
2. Determine the combined weight of
the driver and passengers that will be
riding in your vehicle
3. Subtract the combined weight of the
driver and passengers from
XXX kilograms or YYY pounds
4. The resulting figure equals the avail-
able amount of cargo and luggage
load capacity.
For example, if the XXX amount
equals 1,400 lbs. and there will be
five 150 lbs. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4
6. If your vehicle will be towing a trailer,
load from your trailer will be trans-
fered to your vehicle. Consult the
manual for transporting a trailer to
determine how this may reduce the
available cargo and luggage load
capacity of your vehicle.
Stowing cargo>Load heavy cargo as far forward as
possible – directly behind the back-
rests or the luggage compartment
partition – and as low as possible
>Cover sharp edges and corners
>Do not pile objects higher than the
top edge of the backrest

Roof-mounted luggage rack*A special roof-rack system is available
as an optional extra for your BMW.
Please observe the precautions
included with the installation instruc-
tions.AnchoragesAccess to the anchorages:
To fold up the covers, please use the
tool provided with the roof-rack system.Loading and driving notesRoof-mounted luggage racks raise the
center of gravity of the vehicle when
they are loaded. For this reason, they
exercise a major effect on the vehicle's
handling and steering response.
You should therefore always remember
not to exceed the approved roof load
capacity, the approved gross vehicle
weight or the axle loads when loading
the rack. These weights are listed under
Technical data on page 162.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first so that they are at the bottom. Be
sure that adequate clearance is main-
tained for raising the glass sunroof, and
that objects do not project into the
opening path of the luggage compart-
ment lid.
Secure the roof-mounted luggage cor-
rectly and securely to prevent it from
shifting or being lost during driving.
Drive smoothly and avoid sudden
acceleration and braking. Do not corner
at high speeds.
The roof-mounted luggage rack and the
roof load increase the aerodynamic
resistance: increased fuel consumption
and additional stress on the vehicle's
body are the result.
