The key set
1Master keys with remote control
Each key is powered by an extended-life
battery that is charged automatically in the
ignition lock as you drive. For this reason,
use every master key at least twice a year to
keep its battery charged. Depending on
which master key is recognized when the
vehicle is unlocked, different settings are
called up and carried out in the vehicle, refer
to Key Memory on page31.
2Spare key
For storage in a safe place, e.g. in your wal-
let.
This key is not intended for constant use.
New keys
You can obtain new keys, whether as additional
keys or replacement keys, at your BMW center.
Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed. The
system simultaneously engages and releases
the locks on the
>doors
>luggage compartment lid
>fuel filler door>storage compartment between the back-
rests
>opened manual convertible top.
The central locking system can be operated
>from outside using the remote control or via
the driver's door lock
>from inside via the central locking system
button.
If it is operated from inside, the fuel filler door
will not be locked. Refer to page18.
The anti-theft system is automatically activated
whenever you activate the central locking sys-
tem from outside the vehicle. It prevents the
doors from being unlocked with the lock but-
tons or release handles. The alarm system is
also armed.
In the event of a sufficiently severe accident, the
central locking system unlocks automatically. In
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
from outside
With the remote control
Whenever you unlock or lock the vehicle, you
simultaneously deactivate/activate the anti-
theft system, disarm/arm the alarm system and
switch the interior lamps on/off.
You will find more information about the alarm
system on page25.
Since persons or animals in the vehicle
could lock the doors from the inside,
always take the vehicle keys with you so that
the vehicle can be opened again from the out-
side at any time.<

Clothes hooks
Clothes hooks1 are located on the wind deflec-
tor panels in the rollover bars.
Do not hang heavy objects on the hooks.
If you do, they could endanger the pas-
sengers, for example during braking or evasive
maneuvers.<
Storage
For storage, e.g. to achieve a better view to the
rear when the convertible top is closed, there
are two brackets on the inside of the luggage
compartment lid.
Insert the wind deflector into the brackets.

Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>When attempts are made to start the vehi-
cle
>When there are movements in the vehicle
interior: interior motion sensor, refer to
page26
>To alterations in the vehicle tilt, e.g. as
would occur during attempts to steal the
wheels or tow the vehicle
>To interruption of battery voltage.
The alarm produced by the system in the event
of unauthorized vehicle entry and attempted
theft depends on the country version:
>Sounding of an acoustical alarm for
30 seconds
>Activation of the hazard warning flashers for
approx. five minutes.
Arming and disarming the alarm
system
When the vehicle is locked or unlocked either
with the remote control or at the driver's door
lock, the alarm system is simultaneously armed
or disarmed.
The hazard warning flashers blink once when
the alarm system has been properly armed.
You can have different acknowledgment
signals set to confirm arming and disarm-
ing.<
You can still open the luggage compartment
even when the system is armed by pressing the
button on the remote control, refer to
page17. When it is closed, the lid is once again
secured.
Manual operation of the luggage com-
partment lid triggers the alarm. Refer to
page18.<

>or turn the ignition key to position 1, refer to
page36.
Indicator lamp displays
>The indicator lamp beneath the interior mir-
ror flashes continuously:
The system is armed
>The indicator lamp flashes immediately
after the vehicle is locked:
Doors or luggage compartment lid are not
completely closed. Even if you do not close
the area causing the alert, the remaining
areas are secured and the indicator lamp
flashes continuously after 10 seconds.
However, the interior motion sensor is not
activated
>If the indicator lamp goes out immediately
after the vehicle is unlocked:
No manipulation or attempted intrusions
have been detected in the period since the
system was armed
>If the indicator lamp flashes for 10 seconds
immediately after the vehicle is unlocked:
An attempted entry has been detected in
the period since the system was armed.
After an alarm has been triggered, the indicator
lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
The inclination of the vehicle is monitored. The
alarm system reacts, e.g. to attempts to steal
the wheels or tow the vehicle.
Interior motion sensor*
The system monitors the footwells and the
seating areas of the driver and passenger. Even
when the convertible top is open, the alarm sys-
tem including the interior motion sensor is
armed. Objects falling into the vehicle, e.g.
leaves, can trigger unintentional alarms, refer to
Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
can be deactivated at the same time. In this way
you can avoid unintentional alarms, e.g. in the
following situations:
>In duplex garages
>When the vehicle is being transported on a
car-carrying train
>If animals are to be left in the vehicle.
To deactivate the tilt alarm and interior
motion sensors
Press the button on the remote control
a second time immediately after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are deactivated until
the vehicle is again unlocked and locked.

Controlling the climate for pleasant driving
62
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.
