Luggage compartment lid/TailgateClosing Ð sport wagonYou can pull the tailgate down by
placing both hands in the handle
recesses (arrows).
To close the tailgate, merely press it
down gently. The closing process will
then be carried out automatically.392de689
To avoid injuries, be sure that the
travel path of the luggage com-
partment lid/tailgate is clear when it is
closed, observing the same precautions
as with all closing procedures.
Operate the vehicle only when the lug-
gage compartment lid/tailgate or rear
window is completely closed. Other-
wise, exhaust fumes could penetrate
the interior of the vehicle. Should it be
absolutely necessary to operate the
vehicle with the luggage compartment
lid/tailgate or rear window open:
>Close all windows. Shut the sliding/
tilt sunroof
>Increase the air supply for the air
conditioner or automatic climate
control to a high level. Refer to
page 107 or 111.<

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own indi-
vidual preferences. In engineering your
vehicle, BMW has incorporated a
number of options for personal adjust-
ment that can be programmed into your
vehicle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle
("Vehicle Memory") or the individual
("Key Memory"). Provided that each
person has a separate remote-control
key, you can have your BMW center
enter two personal adjustments for two
different individuals into the system.463de029
The system then relies on a bilateral
data exchange to identify the individual
user and dial in the selected settings
whenever the remote control unit is
used to disengage the door locks.
In order for you to distinguish between
different keys, colored decals are sup-
plied together with the keys.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems. A
few examples follow below:
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your
vehicle
>Activates/deactivates the "Follow me
home" function.Examples for Key Memory:
>Locks the vehicle when you start off
>Automatically adjusts the driverÕs
seat, the exterior mirrors and the
steering wheel position to your per-
sonal programmed settings when you
unlock the vehicle
>The automatic climate control
assumes your preset comfort settings
when you unlock the vehicle.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

OverviewControlsMaintenanceRepairsDataIndex
Air conditioningTemperature
The graduations on the dial
provide general reference
values for the interior temper-
ature. We recommend 70 7
(22 6) as a comfortable setting. When
you start the vehicle, this system
adjusts the air to the selected tempera-
ture as quickly as possible, and then
maintains that temperature constantly.
Air distribution
You can direct the emerging
air toward the windows ,
toward your upper body or
into the footwell . All inter-
mediate settings are also available. In
the setting, there is a low flow of air
onto the windows to keep them free of
condensation.
Air supply
You can control the emerging
air's flow rate through an infi-
nitely-variable range. The
heating and ventilation
become more and more effective as the
air supply settings are increased. In the
"0" setting, the blower and climate con-
trol are switched off and the outside air
supply is blocked.
Rear window defroster
The indicator lamp comes
on to indicate that the rear
window defroster is in operation. The
rear window defroster switches off
automatically.
Cooling
The air conditioning cools
and dehumidifies the
incoming air before reheating it to the
selected temperature. Depending on
the weather, the windshield may fog
over briefly when the engine is started.
You can reduce condensation forming
on the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Recirculated-air mode
You can respond to
unpleasant odors in the sur-
rounding environment by using this
mode to temporarily suspend the flow
of outside air into the vehicle's interior.
The system then recirculates the air
currently within the vehicle.
If your vehicle is equipped with a multi-
function steering wheel
featuring a
recirculated-air button then you can
also select the recirculated-air mode
from this location (refer to page 22).
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.<

Tips for pleasant drivingUse the automatic system, that is,
press AUTO button 6. Select an interior
temperature that you find comfortable.
Detailed setting options are described
for you in the following section.
Your BMW center can program
the settings of your vehicle in such
a manner that, when you unlock the
vehicle with your individualized key,
your own personalized setting for the
automatic climate control is initiated.< Automatic air distribution
The AUTO program
assumes the adjustment of
the air distribution and the air supply for
you and also adapts the temperature to
external influences (summer, winter) to
meet preferences you can specify.
Individual air distribution
You can cancel the AUTO
program by selecting
specific distribution patterns
to suit your own individual
requirements. While the
AUTO program is then deactivated, the
automatic airflow control remains in
operation. The system directs air to the
windows , the upper body and
into the footwells . You can reacti-
vate the automatic air distribution mode
by selecting the AUTO button.
Temperature
You can make individual
temperature settings on the
driver's side or the front
passenger side. Your selection appears
in display 7. The numbers that appear
in the display are reference figures for
interior temperature. We recommend a
setting of 72 7 (22 6) for a congenial
interior climate, even when the air con-
ditioner is in operation. When you start
the vehicle, the system ensures that the
selected temperature is achieved as
quickly as possible. It then maintains
this temperature, regardless of the
season.
Air supply
AUTO appears in
display 9, while the AUTO
program automatically controls the flow
of incoming air, refer to overview on
page 109. You can use "+" and "Ð" to
vary the airflow. When your setting is
displayed by bars, the automatic airflow
is switched off. Automatic air distribu-
tion maintains its setting. You can reac-
tivate the automatic airflow by pressing
the AUTO button.
When you press "Ð " during operation at
minimum blower speed all displays are
canceled: the blower, heating and air
conditioner are switched off. The out-
side air supply is deactivated. By
pressing any button of the automatic
climate control (except the MAX
button 16), you can switch the system
back on.
To defrost windows and remove
condensation
This program quickly
removes ice and conden-
sation from the windshield and the side
windows.

Air conditioning
The air is cooled and
dehumidified and Ð
depending on the temperature setting Ð
warmed again when the air conditioning
is switched on. Depending on the
weather, the windshield may fog over
briefly when the engine is started. You
can reduce condensation forming on
the windows by switching on the air
conditioning.
Condensation forms in the air
conditioning system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Maximum cooling
With the engine running
this program provides
maximum cooling at outside tempera-
tures above approx. 41 7 (5 6).
60 7 (16 6) appears in the tempera-
ture display 9, and the system reverts to
the recirculated-air mode while simulta-
neously providing maximum airflow
through the vent outlets only. That is
why you need to keep these open if you
select this program.
Automatic recirculated-air
control (AUC)
You can respond to
unpleasant external odors
by temporarily stopping the flow of out-
side air. The system then recirculates
the air currently within the vehicle.
Press the button repeatedly to run
through the following control sequence:
>Indicator lamps off: outside airflow
operational
>Left-hand indicator lamp on Ð AUC
mode: the system recognizes pollut-
ants in the outside air and blocks the
flow of air when necessary. The
system then recirculates the air cur-
rently 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-hand indicator lamp on: the
flow of external air into the vehicle is
permanently blocked. The system
then recirculates the air currently
within the vehicle.
If you have a multifunction steering
wheel with the recirculated-air button
(refer to page 22), you can also use it to
switch between "Off" and the recircu-
lated-air mode or AUC and the recircu-
lated-air mode.
If the windows should fog over in
the recirculated-air mode, switch
the recirculated-air mode off and
increase the air supply as required.< Rear window defroster
When the rear window
defroster is activated, the
indicator lamp comes on. The rear
window defroster switches off automat-
ically.
