The key set
1Every master key with remote control con-
tains an extended-life battery as a power
supply, which is charged automatically in
the ignition lock as you drive. You should
use each master key at least twice a year in
order to maintain the charge condition.
Depending on which master key is detected
by the vehicle during unlocking, different
settings in the vehicle are requested and
executed, refer to Key Memory below.
2Spare key for storage in a safe place, such
as in your wallet.
This key does not fit in the locks of the lug-
gage compartment lid and the hotel func-
tion, refer to page32. This is an advantage
when valet parking at a hotel, for example.
The key is not intended for constant use.
New keys
New, additional or replacement keys are avail-
able at your BMW center.

How the system functions
Doubtless you have often reflected on how
great it would be if you could configure your
vehicle's various adjustment settings to meet
your own personal requirements. BMW has
designed several freely selectable options into
the vehicle during its development. You can set
these as desired via the Control Center.You can have up to four different basic settings
adjusted for four different persons for the spe-
cific keys. The only requirement is that each
person uses his or her own master key with
remote control.
When your vehicle is unlocked with the remote
control, the vehicle recognizes the individual
key by means of a data exchange and makes
adjustments accordingly.

either unlock only the driver's door or the
entire vehicle, refer to page29.

Central locking system
The concept
The central locking system is ready for opera-
tion whenever the driver's door is closed. This
simultaneously engages and releases the locks
on the following:
>Doors
>Compartment in the front center console
>Luggage compartment lid
>Fuel filler door
The central locking system can be operated
from the outside
>via the remote control
>via the door lock
and from inside via the button for the central
locking system.
If operated from the inside, the fuel filler door
and the compartment in the front center con-
sole are not locked, refer to page31.
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 using the lock but-
tons or door handles. The alarm system is
armed/disarmed at the same time. The dome
light is also switched on and off with the remote
control.
You can find more detailed information on the
alarm system on page34.In the event of a serious accident, the central
locking system unlocks automatically. The haz-
ard warning flashers and interior lamps also
switch on.

Hotel function
The hotel function locks the compartment in
the front center console and the luggage com-
partment lid separately and disconnects them
from the central locking system. The spare key,
refer to page28, does not fit the lock for the
hotel function. If you then only hand over the
spare key, e.g. at a hotel, it is not possible to
access the luggage compartment or the com-
partment in the front center console.
Turn the key to the right, refer to illustration, and
remove.
The hotel function is only activated after subse-
quent locking or unlocking of the vehicle. This
locks the luggage compartment lid and the
compartment in the front center console and
disconnects them from the central locking sys-
tem.
In the event of an electrical malfunction
For manual unlocking, turn the master key all
the way to the right:
The compartment in the front center console is
unlocked.
If unlocking was manual, the lock has to
be returned to the home position, i.e. all
the way back to the left, before reactivation of
the hotel function.<
Luggage compartment lid
Coupe: the luggage compartment lid
swings to the rear and upward when
opened. Make sure there is sufficient free
space.<

lutely necessary to operate the vehicle with the
luggage compartment lid open:
1.Coupe: close both windows and the glass
sunroof
*.
Convertible: with closed top, close all win-
dows.
2.Increase the air volume of the automatic
climate control to a high level, refer to
page95.
Luggage compartment
There are four lashing eyes on the inner corners
of the luggage compartment for securing lug-
gage nets
* or securing straps to fix luggage in
position.

ward in the direction of travel, refer to arrow.
This folds the convertible top compartment
floor upward.
Before opening the convertible top, execute
this procedure in reverse order.
The convertible top cannot be opened if
the convertible top compartment floor is
folded up.<
Alarm system
The concept
The vehicle alarm system responds:
>To the opening of doors, the hood, or the
luggage compartment lid
>To movements in the vehicle interior: inte-
rior motion sensor, see below
>To changes in the vehicle's tilt if someone
attempts to steal the wheels or tow the
vehicle
>To interruptions in battery voltage
The system responds to unauthorized vehicle
entry and attempted theft by simultaneously
activating:
>An acoustic alarm, which lasts for a period
of approx. 30 seconds
>The hazard warning flashers for approx.
5minutes
>The high beams, which flash on and off in
the same rhythm
Arming and disarming alarm system
When you lock or unlock the vehicle, either with
the remote control or at the door lock, the alarm
system is armed or disarmed at the same time.
The system indicates that it has been correctly
armed by switching on the hazard warning
flashers for a single cycle and by emitting an
acoustic signal.
You can also open the luggage compartment lid
with the system armed using the button on
the remote control, refer to page30. When the
luggage compartment lid is closed, it is locked
again and monitored.
Switching off alarm
>Unlock the vehicle using the remote control,
refer to page29,
>or turn the ignition key to position 1, refer to
page54.

Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking:
door(s) or luggage compartment lid are not
completely closed. Even if you do not close
the alerted area, the system begins to mon-
itor the remaining areas, and the indicator
lamp flashes continuously after approx.
10 seconds. However, the interior motion
sensor is not activated.
>The indicator lamp goes out after unlocking:
no manipulation or attempted intrusions
have been detected in the period since the
system was armed.
>After unlocking, the indicator lamp flashes
until the key is inserted into the ignition
lock, but will not do so for longer than
roughly 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
*
must be completely closed.Convertible:
Monitors the interior up to the height of the seat
cushions. This means that the alarm system,
including the interior motion sensor, is armed
even if the convertible top is open. Falling
objects, e.g. leaves, can trigger false alarms,
refer to Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off the tilt alarm sensor and
interior motion sensor
Press the button on the remote control
once again directly after locking.
The indicator lamp lights up briefly and then
flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the vehicle is unlocked and locked again.
Windows
To prevent injuries, exercise care when
closing the windows and keep them in
your field of vision until they are shut.
When leaving the vehicle, always remove the
ignition key and close the doors to prevent chil-
dren from operating the power windows and
injuring themselves.<

Rear window
Ignition key in position 1 or greater, refer to
page54:
1.Briefly press button1:
The LEDs in button 1 and switch 2 light up.
2.Press switch 2:
>Up to the resistance point:
The rear window continues to open for
as long as you hold the switch.
You can close the rear window in the
same manner by pulling the switch.
>Briefly press the switch beyond the
resistance point:
The rear window opens automatically.
Briefly press the switch again to stop the
opening movement.
Briefly press button 1 again to deactivate the
function. The LEDs go out.
The rear window opens and closes auto-
matically when you open or close the con-
vertible top.<
After switching off ignition
You can still operate the windows:
>for approx. 15 minutes when the ignition
key is in position 1.
>for approx. 1 minute when the ignition key is
in position 0 or has been removed; but in the
convertible, only for as long as a door has
not been opened.
For information on using the convenience oper-
ation mode at the door lock or with the remote
control, refer to page30 or31.
Anti-trapping mechanism
If the closing force rises beyond a predefined
threshold during closing, the system will imme-
diately stop moving the window prior to lower-
ing it slightly.
Convertible: the back windows and rear
window are not equipped with an anti-
trapping mechanism.<
Despite the anti-trapping mechanism,
you should inspect the travel path of the
front side window prior to closing it, as the
safety feature could fail to detect certain kinds
of obstructions, such as very thin objects, and
the window would continue closing.
Pulling the switch beyond the resistance point
and holding it limits the response of the anti-
trapping mechanism. Under these conditions,
the window will respond to forces beyond a
defined threshold by only opening a few inches/
millimeters.
If you pull the switch past the resistance point
again within approx. 4 seconds and hold it there,
the anti-trapping mechanism will be deacti-
vated.<
Accessories in window area
After installing any accessory – such as a
clamp-on antenna for a portable phone – within
the window's travel range, you will need to have
the system reinitialized for use under the new
conditions. Please contact your BMW center for
assistance.
Coupe:
Glass sunroof, electric
with raise function*
To prevent injuries, exercise care when
closing the glass sunroof and keep it in
your field of vision until it is shut.
When leaving the vehicle, always remove the
key and close the doors, as otherwise children
could operate the sunroof and injure them-
selves.<
