The fully automatic convertible top
*
The fully automatic convertible top
combines assured protection from the
weather with a one-touch operation.
Here are a few tips to ensure that you
get the most enjoyment out of driving
your convertible.
It is advisable to close the convertible
top when the vehicle is parked. The
closed convertible top not only protects
the passenger compartment from un-
foreseeable damage from the weather,
it also provides a certain degree of theft
protection. In addition, keep valuables
only in the locked luggage compart-
ment, even with the convertible top
closed.
Never mount a roof-mounted luggage
rack on the convertible top.
To prevent damage, do not operate the
convertible top at temperatures below
14 7 (–10 6).
To conserve the battery, operate the
convertible top only with the engine
running if at all possible.
The convertible top operation is
completely automatic. In rare in-
stances, some manual support may be
necessary (see Note in next column
but one).
Operate the convertible top only when
the vehicle is stationary. Do not start to
drive while operating it, either, because
the procedure could be interrupted
when the top hits certain positions.
A partially open convertible top can
lead to damage or injury.
If you initiate convertible top operation
with the vehicle stationary and then
start driving, e.g. at a traffic light, you
can completely carry out the initiated
operation. To do this, press and hold
the corresponding button again.
Give the respectively applicable traffic
rules preference during convertible top
operation, as otherwise you will be in
violation of the law.
Remove any foreign objects from the
windshield frame before closing the
convertible top, otherwise, they could
hinder the opening and closing of the
convertible top.
Do not place any objects on the con-
vertible top, since they would fall off
when the convertible top is operated
and cause damage or injuries.
While driving, always close the rear
power windows first, or close all 4 win-
dows at the same time, otherwise the
windows may not shut tightly at higher
speeds.cDo not reach into the convertible
top mechanism during opening
and closing. Keep children away from
the moving parts of the convertible top
during operation.
The automatic process is immediately
interrupted if the button for actuating
the convertible top is released. The pro-
cess can be continued in the direction
desired by pressing the switch.c
If the convertible top has been
stored in the convertible top com-
partment for an extended period of
time, e.g. during the winter months be-
cause the hardtop
* has been used, it
may be necessary to manually support
the top when closing it automatically for
the first time:
Should the convertible top stop shortly
before it reaches the end of the closing
operation, press from outside against
the front of the convertible top frame
while pressing the switch to help the
top along until it begins moving again
on its own.c

Dynamic Stability Control (DSC) The conceptDSC 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 (un-
dersteering or oversteering, for exam-
ple) and helps hold the vehicle on a
sure course by intervening via the
engine and by braking intervention at
the individual wheels.
The system activates automatically
each time you start the engine.46cus012
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is active and governs drive
force and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the but-
ton. You can continue to drive the vehi-
cle normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button, the indicator lamp
comes on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 118.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 173.

Automatic climate controlAir supply

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 for 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, heater and air conditioner are
switched off, and the air supply stops.
You can reactivate the system by
pressing any button of the automatic
climate control.
Defrost the windshield and side
windows
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 tem-
perature 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 when outside air temperatures
are 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, which 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 air flow from
the outside. The system then recircu-
lates the air already within the vehicle.
By repeated actuation of the button,
you can select three different operating
modes.
>Indicator lamps off: fresh air flows
into the vehicle
>Left-hand indicator lamp on – AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates 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.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply
as required.<
