Opening and closing
22 the top not only guards the passenger com-
partment from unforeseeable damage from
the weather, but also affords a degree of
protection against theft. In addition, only
keep valuables in the locked luggage com-
partment, even with the convertible top
closed
>Never mount a roof-mounted luggage rack
system on the convertible top
>To avoid damage, do not operate the con-
vertible top at temperatures below 147/
–106.
To avoid permanent damage from mois-
ture, never store the convertible top while
it is wet.
Driving when the opening or closing process
has not been completed can cause vehicle
damage or personal injury.
Do not lay objects on the convertible top, since
they could fall off when the convertible top is
operated and cause damage or injuries.
Do not reach into the convertible top mecha-
nism during opening and closing. Keep children
away from the moving parts of the convertible
top during operation.<
If possible, only operate the convertible
top with the vehicle stopped, as other-
wise the process may be interrupted.
If you set the convertible top in motion while the
vehicle is stationary and then have to start sud-
denly, for instance at a traffic light, you can still
complete the procedure by driving as slowly as
possible and again holding the corresponding
button pressed.
At higher speeds, a vacuum effect in the pas-
senger compartment can cause the convertible
top to begin fluttering. Increase the air supply
so that a low pressure draft does not occur in
the vehicle.<
Opening and closing

erly.<

Kickdown:
For rapid acceleration, e.g. during passing,
depress the accelerator pedal completely. You
achieve maximum acceleration.
To switch back to sequential mode: tap the
selector lever again to the right toward D, or
change the current gear via the shift paddles or
the selector lever.
When driving off on inclines, drive
smoothly without pausing. Do not keep
the vehicle in place by depressing the accelera-
tor pedal; instead, apply the parking brake. Oth-
erwise, the gearbox could overheat.<
Shifting gears
With selector lever
>To upshift, tap the selector lever toward +
>To downshift, tap the lever toward –.
With shift paddles on steering wheel
>To upshift, pull one of the shift paddles
>To downshift, push the paddle.
In the following situations, the SMG in the
sequential mode assists you:
>The transmission will only execute upshifts
and downshifts that will result in an appro-
priate combination of vehicle speed and
engine rpm. For instance, downshifts that
would result in excessive engine speed
cannot be executed
>During a stop the gearbox is automatically
downshifted into first gear
>Shortly before a gear-dependent minimum
speed is reached, the gearbox automatically
shifts down without you taking any action.
Malfunction
The warning lamp lights up. The trans-
mission system is malfunctioning.
Avoid heavy loads.
All of the selector lever positions can continue
to be engaged; in the forward drive positions,
however, the vehicle will be operating in a
restricted gear range only. Have the system
checked as soon as possible.
Towing and tow-starting, refer to page98;
Jump starting, refer to page97.
Overheating
An acoustic warning signal sounds. The gear-
box is overheating. If possible, stop the vehicle
or drive off swiftly so that the system can cool
off again.
Driving Dynamic Control
Driving Dynamic Control allows your BMW to
react in a sportier driving style at the touch of a
button:
>The engine responds more spontaneously
to any motion of the accelerator pedal
>The vehicle is steered more directly and
traction is enhanced
>Cruise control:
When the speed last stored is called up, this
speed is attained more quickly.
Additional features with SMG:
>Gears are shifted more quickly
>The engine speed range is optimally utilized
in the drive mode.
With automatic transmission:
>The Sport program is activated.

The displays shown in the illustration appear for
a few seconds when the ignition key is in
position 1 or after the engine is started.
The next service due appears with the message
OIL SERVICE or INSPECTION, together with
the distance remaining in miles – in kilometers
in Canada – before the next scheduled service.
The computer bases its calculations of the
remaining distance on the preceding driving
style.
A flashing message and a minus sign in front of
the number mean that the service interval has
already been exceeded by the distance shown
on the display. Please contact your BMW center
for an appointment.
Outside temperature

the display in the instrument cluster always
shows the outside temperature.

Controlling the climate for pleasant driving

Tips for pleasant driving
Use the automatic system – switch on with
AUTO button 6. Select the desired interior tem-
perature.
Detailed setting options are described for you
below.
Automatic air distribution and supply
The AUTO program assumes the
adjustment of the air distribution and
air supply for you and in addition
adapts the temperature to external
influences, summer or winter, to meet prefer-
ences you can specify.
In the AUTO program, the air conditioning
mode is also turned on at the same time.
The AUTO program functions only to a
limited extent when the convertible top is
open.<
Individual air distribution
You yourself can direct airflow onto
the windows , toward the upper
body and into the footwell . The
arrow lights up. The automatic air
supply remains unchanged. All intermediate
settings are possible. By pressing the AUTO
button, you can reactivate the air distribution.
Temperature
The interior temperature that
appears on the display panel is a gen-
eral figure intended for reference
purposes. When you start the vehi-
cle, the system ensures that the selected tem-
perature is reached as quickly as possible,
regardless of the season. It then maintains this
temperature.
Air supply/blower
Turn the rotary control to adjust the
air supply. This shuts off the auto-
matic air supply. The arrow lights up.
The automatic air distribution
remains unchanged. You can reactivate the
automatic air supply by pressing the AUTO but-
ton.When you turn the rotary control toward zero:
the blower, heating and air conditioner are
switched off, and the air supply is stopped. You
can reactivate the system by turning the control
toward the right again.
To defrost windows and remove
condensation
This program quickly removes ice
and condensation from the wind-
shield and the side windows.
Maximum cooling
Above an outside temperature of
327/06 and with the engine run-
ning, you achieve a maximum cooling
effect as quickly as possible. At the
same time, the air conditioning is turned on.
The temperature is set to the lowest possible
value. The system switches to the recirculated
air mode, and air flows at maximum blower
speed from the ventilation grills in the upper
body area only. Therefore, the air outlets must
always be open when you select this program.
Air conditioning
The air is cooled and dehumidified
and, depending on the temperature
setting, rewarmed.
Depending on the weather, the wind-
shield may fog over briefly when the engine is
started.
The air conditioning system is automatically
switched on when you use the AUTO program.
Condensation forms during operation of
the air conditioning system, which then
exits under the vehicle. Traces of condensed
water on the ground underneath the vehicle are
thus normal.<
Outside air/Automatic recirculated air
control AUC/recirculated air mode
You can respond to unpleasant
external odors or pollutants by tem-
porarily stopping the flow of outside
air. The system then recirculates the
air currently within the vehicle.
