are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react to this below.

If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

Driving when the opening or clos-
ing process has not been com-
pleted can cause vehicle damage or
personal injuries.
Do not reach into the convertible top
mechanism during opening and closing.
Keep children away from the moving
parts of the convertible top during
operation.<
If possible, only operate the con-
vertible top with the vehicle
stopped, as otherwise the process may
be interrupted.
If you set the convertible top in motion
with the vehicle stationary and then
have to start suddenly – for instance, at
a traffic light – you can still complete
the operation by driving as slowly as
possible and again pressing and main-
taining pressure on the button.<
To close the electric power win-
dows while driving, always be
sure to first close either the rear win-
dows, or all 4 windows at the same
time, otherwise, at high speed, the win-
dows may not close tightly.<
At higher speeds, the ensuing
vacuum in the passenger com-
partment can cause the convertible top
to begin fluttering. Increase the air sup-
ply via the ventilation controls so that a
vacuum does not occur in the vehicle.<
Opening and closing1To close

2. Ensure that the convertible top com-
partment panel in the luggage com-
partment is folded down, see
page 37; otherwise, it will not be
possible to open the convertible top
3. Make sure that the luggage compart-
ment lid is closed
4. Press and hold the corresponding
button for convertible top operation.
The luggage compartment lid can-
not be opened while the convert-
ible top is in motion.<
During convertible top operation
the rear window moves toward the
passenger compartment. To prevent
injuries, make sure that the closing path
of the convertible top is unobstructed.<
After having been stored for an
extended period of time in the
convertible top compartment, e.g. dur-
ing the winter months because the
hardtop was being used, you may have
to support the convertible top by hand
when closing it for the first time.
If the convertible top should halt right
before the closing phase is completed,
press against the front part of the con-
vertible top frame from the outside to
help the closing process along. Keep
pressing the button while doing so until
the top starts up again on its own.<
Indicator lamps>The red indicator lamp is lit whenever
the convertible top is in motion. It
goes out as soon as the opening or
closing operation has been com-
pleted

the button is released, the convertible
top has not yet been opened or
closed completely. You can resume
operation in the desired direction by
pressing the button again
>If the yellow indicator lamp lights up
continuously with the button pressed,
the convertible top compartment
panel has been raised and the top
cannot be moved.
The side windows move down slightly
whenever the button for operating the
convertible top is pressed.
They will go back up if you keep holding
the button down for more than
2 seconds after the opening or closing
process has been completed and the
indicator lamp has gone out.InterruptionThe convertible top stops moving
immediately when the button is
released. You can resume operation in
the desired direction by pressing the
button again
Do not close the side windows
using the power window switches

Shifting gears with shift paddles on
steering wheel:
>To upshift, briefly pull the right pad-
dle +
>To downshift, briefly pull the left pad-
dle –.
Shift paddles with various widths
matched to the shape of your
hand are available from your BMW cen-
ter.<
Shifting gears with selector lever:
>To upshift, pull the selector lever
backward in the '+' direction
>To downshift, push the selector lever
in the '–' direction.
No automatic upshifting is carried out in
the sequential mode.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations the
SMG Drivelogic anticipates your
actions in the sequential mode:
>Upshifts and downshifts are only exe-
cuted at appropriate combinations of
engine rpm and vehicle speed. For
instance, downshifts that would
result in excessive engine speed are
not executed
>During a stop the gearbox is auto-
matically downshifted into the first
gear so that, e.g. before a traffic light,
it is only necessary to accelerate to
continue driving
>As speed diminishes, the gearbox
downshifts automatically, without you
taking any action, just before the
vehicle slows to below each gear's
minimum speed.D - Automated modeEach time the engine is started, the
automated mode is activated as soon
as you move the selector lever into the
forward driving position.
In the automated mode all forward
gears are shifted automatically.To switch from sequential to automated
mode: tap the selector lever to the right
toward 'D'. Watch the display in the
instrument cluster, refer to page 71.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely – kickdown. The gearbox
now downshifts depending on the
selected driving program.
Even in the automated mode, you can
help specify the shifting point: if a gear-
dependent minimum speed is
exceeded, you can upshift by slowly
reducing pressure on the accelerator
pedal. In the process, the respective
driving situation is detected by sensors
and taken into account.

DrivelogicDrivelogic makes various driving pro-
grams available to you.
Press the Drivelogic repeatedly until the
desired driving program is shown in the
SMG display of the instrument cluster,
refer to page 71.
In the automated mode you can select
from five driving programs ranging from
convenience mode/winter operation to
sporty and highly dynamic.
In the first automated driving program,
starting off takes place in second gear,
which is advisable under winter road
conditions with ice and snow.
In the sequential mode you can choose
from six driving programs ranging from
balanced, dynamic driving – 1 – to
sporty, puristic driving – 6. The sporty,
puristic driving program can only be
activated with the Dynamic Stability
Control (DSC) deactivated, refer to
page 86.
To maintain vehicle stability,
always drive with the DSC acti-
vated on whenever possible.<
Following each change between the
sequential and the automated mode,
the last driving program selected in the
respective mode is active. Exception:
instead of the last selected sequential
driving program 6, program 5 is acti-
vated only after the engine has been
started again.
Your vehicle is set so that when
the engine is started, the last
selected driving program saved in your
key is activated for each shifting
mode.<
Gradient assistanceThe gradient assistance enables start-
ing off on grades with virtually no roll-
back. It can be activated in the sequen-
tial and automated mode with the vehi-
cle stopped and can be used for both
forward and reverse driving.
The vehicle may roll slightly before
it is held by the gradient assis-
tance after releasing the footbrake.
Two seconds after the footbrake is
released, the vehicle begins to roll, as it
is no longer held with the gradient
assistance.<
1. Depress footbrake with vehicle
stopped
2. Activate the gradient assistance by
pulling the left paddle for at least
0.5 seconds. An increase in the
engine speed indicates that the gra-
dient assistance is activated
Briefly pulling the left paddle again
deactivates the gradient assis-
tance again.<
3. Release the footbrake and start off
within two seconds.
The gradient assistance must be reacti-
vated before each use.

Dynamic Stability Control DSCThe conceptDSC maintains 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, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and,
within physically feasible limits, helps
keeping the vehicle on a steady course
by reducing the engine speed and
brake applications to the individual
wheels.
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. Allow only authorized
technicians to perform service proce-
dures on the DSC.
At first, you may need some time to
become accustomed to this system's
intervention. However, it guarantees
optimum drive force and at the same
time, the best possible vehicle stabil-
ity.<
Indicator lamp
The indicator lamp in the instru-
ment cluster will go out shortly
after the ignition has been
switched on, refer to page 19.
>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: the system has been
deactivated via the button or is
defective.
Please consult your BMW center for
repairs.
You can continue to drive the vehicle
normally without DSC.

Tips for pleasant drivingUse the automatic mode – switch on
with AUTO button 6. Select the desired
interior temperature.
Detailed setting options are described
for you in the following sections.
You can make the settings of your
vehicle in such a manner that,
when you unlock the vehicle with the
remote control of your personal key,
your own personalized setting for the
automatic climate control is initiated. supply
The AUTO program adjusts the
air distribution and the air sup-
ply for you and in addition adapts the
temperature to external influences –
summer, winter – to meet preferences
you can specify.
Individual air distribution
You can cancel the AUTO pro-
gram by selecting specific dis-
tribution patterns to suit your
own individual requirements.
While the AUTO program is then deacti-
vated, the automatic airflow control
remains in operation. Air flows onto
the windows , toward the upper
body , and into the footwell . You
can reactivate the automatic air supply
by pressing the AUTO button.Temperature
The interior temperature that
appears in the display panel is a
general figure intended for refer-
ence purposes. We recommend
727/+226 as a comfortable setting,
even if the air conditioning is on. When
you start the vehicle, the system
ensures that the selected temperature
is reached as quickly as possible. It
then maintains this temperature,
regardless of the season.
To select the units of measure 6/7
of the display, refer to page 83.
Air supply/Blower
By pressing the upper or lower
button, you can vary the air sup-
ply. This deactivates the auto-
matic air supply – the AUTO display dis-
appears from the panel. Nevertheless,
the automatic air distribution remains
unchanged. You can reactivate the
automatic air supply by pressing the
AUTO button.
When the lowest blower speed is set
and you press the lower 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.To defrost windows and remove
condensation
This program quickly removes
ice and condensation from the
windshield and the side windows.
Air conditioning
The air is cooled and dehumidi-
fied and – depending on the
temperature setting – rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started. Air conditioning helps
prevent the windows from fogging up.
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.<
