Electric power windows Convertible top Operating all the side windowsFrom ignition key position 1:
To open:
>Press the switch up to but not past
the resistance point:
All windows will continue to lower as
long as you continue to press the
switch
>Press the switch briefly past the
resistance point:
All windows will move automatically.
Pressing the switch again stops the
opening cycle.
To close: you can close all windows in
the same manner by pulling the switch.
The fully automatic convertible top
combines assured protection from the
weather together with simple and easy
handling.
So that you will get the most out of your
convertible, here are a few tips:
>It is advisable to close the convertible
top when the vehicle is being parked.
The closed convertible top not only
protects the passenger compartment
from unforeseeable damage from the
weather, it also provides a certain
degree of theft protection. In addi-
tion, keep valuables only in the
locked luggage compartment, even
with the convertible top closed.
>Never mount a roof-mounted luggage
rack on the convertible top.
>At temperatures below 15 7
(–10 6) do not open or close the
convertible top to prevent damage.
Never store the convertible top
while it is wet to avoid permanent
damage from moisture.<
Driving the vehicle before the top
has opened or closed completely
can lead to vehicle damage and/or
personal injury.
Whenever possible, always ensure that
the vehicle remains stationary for the
entire duration of the opening/closing
process. Setting the vehicle in motion
before the process is completed may
cause the top to stop moving prema-
turely.
If you initiated convertible top operation
while the vehicle was standing still, and
then started to drive off, at a traffic light,
for example, you can complete the
process while traveling at a moderate
rate of speed. To do this, keep pressing
the proper button.
Traffic laws applicable in your area take
precedence when you operate the
convertible top, however, otherwise
you may be breaking the law.
Before closing the convertible top,
remove any objects from the windshield
frame that could keep the convertible
top from closing properly.
Do not lay objects on the convertible
top, since they would fall off when the
convertible top is operated and cause
damage or injuries.
Do not reach into the convertible top
mechanism during opening and closing.

Dynamic Stability Control (DSC)

The concept

DSC helps maintain vehicle stability,
even in critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions
(understeering or oversteering in
curves, for example) and holds the
vehicle on course by intervening via the
engine and by braking intervention at
the individual wheels within the limits
defined by the laws of physics.
The system starts up automatically
each time you start the engine.
The laws of physics cannot be
repealed, even with DSC. The
results of driving irresponsibly rest with
the driver. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks. Do not make any modifications to
the DSC system. Service procedures
on the system are to be performed by
authorized technicians only.<
You will find additional details
concerning DSC in the chapter
"Advanced technology" on page 170.
Indicator lamp
The indicator lamp on the instru-
ment cluster will go out shortly
after the ignition has been
switched on. Refer to page 21.
>Indicator lamp flashes: the system is
active and is controlling the drive
torque based on driving conditions
>If the indicator lamp fails to go out
after the engine has been started, or
if it comes on during normal driving
and stays on: there is a system
malfunction or the system was deac-
tivated with the button. You can
continue to drive the vehicle
normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button – the indicator lamp
comes on and stays on.
When DSC is deactivated, you are
driving with conventional power
transfer.
We recommend that you turn the
system off for increased traction:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving with snow chains.
Refer also to page 110.
To help maintain driving stability,
drive with the DSC activated
whenever possible.< To reactivate the systemPress the button again; the indicator
lamp goes out.

Automatic climate control Air supply (fan)
By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control of the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heating and air conditioner are
switched off, and the air supply is
stopped. You can reactivate the system
by pressing any button for the auto-
matic climate control.
Defrosting the windows and
removing condensation
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed when
the air conditioner system is switched
on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Use the button to switch the air condi-
tioner off at outside temperatures
below approx. 41 7(+5 6). This will
help to prevent the windows from
fogging over.
If the windows fog over after switching
the air conditioner off, switch it back
on.
Condensation forms in the air
conditioner system during opera-
tion, that then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated air control
(AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the airflow from
the outside. The system then recircu-
lates the air already within the vehicle.
By repeated actuation of the button,
you can select one of three different
operation modes.
>Indicator lamps off: outside air always
flowing into the vehicle
>Left-hand indicator lamp on – Auto-
matic mode: the system detects
pollutants in the outside air and
responds by deactivating the outside
airflow as required. The system then
recirculates the air already within the
vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
