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.<

If the luggage compartment lid has not been
locked separately, you can open it with this but-
ton in the footwell on the driver's side when the
vehicle is stationary.

path of the luggage compartment lid is
clear when it is closed, following the same pre-
cautions as with all closing procedures.<

Windows
To open and close a window
Ignition key in position 1 or higher:
>Press the switch downward until you feel
resistance: the window continues to move
downward as long as you continue to press
the switch
>Tap the switch past the pressure point:
the window moves downward automati-
cally. Tapping the switch again stops the
opening cycle.
You can close the window in the same manner
by pulling the switch upward.
If you wish, you can have this special fea-
ture activated/deactivated.<
After the ignition has been switched off
You can still open or close the windows for up to
15 minutes, as long as no one opens any of the
doors.
When leaving the vehicle, always remove
the ignition key from the lock and remem-
ber to close the doors, since children could oth-
erwise operate the windows and injure them-
selves, etc.<
For convenience operation via the remote con-
trol or the door lock, refer to page17 or18,
respectively.
Pressure-sensitive finger guard
system
If the closing force exceeds a certain value while
a window is being raised, the system will
respond by stopping the window and then
retracting it a small distance.Despite the finger guard system, make
sure that the windows can close without
obstruction, since in some cases, e.g. with thin
objects, it is not guaranteed that the closing
operation will be interrupted.
The finger guard system function is restricted
when the switch is pulled and held beyond the
pressure point.<
After a power supply interruption
After a power supply interruption, for instance
after disconnecting the battery, the pressure-
sensitive finger guard system must be reinitial-
ized:
Ensure that the doors and convertible top are
closed before initializing. Perform the following
procedure twice for each window:
>Open and close the window completely
>With the window closed, keep pulling the
switch upward for approx. 1 second.
Manual convertible top
The fabric top offers perfect protection against
the weather and it can be opened easily and
quickly by one person alone.
Here are a few tips so that you get the most out
of your BMW:
>It is advisable to close the convertible top
when the vehicle is parked. The closed con-
vertible top not only protects the passenger
compartment from unforeseeable damage
from the weather, but also provides a cer-
tain degree of theft protection
>In addition, only keep valuables in the
locked luggage compartment, even with the
convertible top closed
>When the convertible top is open, the cen-
tral locking system also locks the release
button for the convertible top. The convert-
ible top cannot be operated. This provides
better theft protection for valuables stored
in the luggage compartment
>Never mount a roof-mounted luggage rack
system on the convertible top.

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
