preselected temperature setting as the
basis for adjusting the interior climate to
adapt to external influences: summer, win-
ter.

Temperature adjustment
You can turn to select the
desired temperatures for the
driver's and passenger sides.
Your settings appear on the
Control Display's status line.
The figures in the display provide a general
indication of interior temperature. When
you start the vehicle, this system ensures
that the selected temperature is achieved
as quickly as possible. It then maintains this
temperature, regardless of the season.
Defrosting windows and removing
condensation
This program quickly removes
ice and condensation from the
windshield and door windows.
Adjusting air supply manually
You can adjust the air supply by
turning. The automatic air sup-
ply control is operational when-
ever you see your selection rep-
resented by a bar on the
Control Display's status line. The automatic
air distribution remains in operation as
before. You can reactivate the automatic air
supply mode with the AUTO button.
Switching air conditioner mode on
and off manually
The air conditioner cools and
dehumidifies the incoming air
before also reheating it as
required, according to temperature setting.
Depending on the weather, the windshield
may fog over briefly when the engine is
started.
The air conditioner comes on automatically
when you select the AUTO program.
Maximum cooling
This program quickly provides
maximum cooling.
The temperature display reverts
to 607/166 while the system
switches to the recirculated-air mode and
starts to provide maximum air supply through the vent outlets only. For this rea-
son you should ensure that these outlets
are open before selecting this program.
Outside air/AUC Automatic
recirculated-air control/recirculated
air
You can respond to unpleasant
odors or pollutants in the imme-
diate environment by tempo-
rarily suspending the supply of outside air.
The system then recirculates the air cur-
rently within the vehicle. AUC executes this
function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle
>Left indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required. The sys-
tem then recirculates the air currently
within the vehicle.
Depending upon air quality, in the auto-
matic mode the system may start to
alternate between its outside-air and
recirculated-air modes
>Right indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is permanently blocked. The
system then recirculates the air cur-
rently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required.<
Residual heat mode
The system uses the warmth
stored in the engine to heat the
interior when the ignition is off,
for instance, while the vehicle
is stopped at a school to pick
up a child.
You can adjust the automatic climate con-
trol's settings when the ignition lock is in
the radio mode. The system blows heated

Battery
Battery care
The battery is 100 % maintenance-free, i.e.,
the electrolyte will last for the life of the bat-
tery when the vehicle is operated in a tem-
perate climate. Your BMW center will be
happy to advise you on all questions con-
cerning the battery.
Charging battery
Only charge the battery in the vehicle via
the terminals in the engine compartment
with the engine off. Connections, refer to
Jump-starting on page210.
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the
battery switch located behind the trim
panel on the right side of the luggage com-
partment to OFF. This reduces the current
flow from the battery for the period during
which the vehicle remains parked. A mes-
sage appears in the Check Control. Please
take note of the supplementary information
provided on the Control Display.
Disposal
Have old batteries disposed of follow-
ing replacement at your BMW center
or bring them to a collection point. Maintain
the battery in an upright position for trans-
port and storage. Always secure the battery
to prevent it from tipping over during trans-
port.<
Power failure
Following a temporary power failure, e.g. in
the case of a flat battery, some equipment
is subject to restricted use and must be
reinitialized. Individual settings are also lost
and must be updated again:
>Seat, mirror and steering wheel memory
The positions must be stored again,
refer to page55
>Time and date
Must be updated again, refer to
page90
>Radio
Stations must be stored again, refer to
page 154
>Navigation system
The operability must be waited for, refer
to page130.
Fuses
Never attempt to repair a blown fuse,
and do not replace a defective fuse
with a substitute of another color or amper-
age rating, as this could lead to a circuit
overload, ultimately resulting in a fire in the
vehicle.<
Spare fuses are located on the fuse strip in
the glove compartment; plastic tweezers
can be found at the fuse holder in the lug-
gage compartment.
In glove compartment
Press the tab on the cover to the front, then
fold up the cover.
