Unlocking and opening doors
>Either unlock both doors together with
the button for the central locking sys-
tem and then pull the door handle
above the armrest or
>pull the door handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
Locking doors
>Use the central locking button to lock
both of the doors simultaneously, or
>press down the safety lock button of the
desired door. To prevent you from
being locked out, the open driver's door
cannot be locked using the safety lock
button.
Because any persons or animals left
unattended in a parked vehicle could
lock the doors from the inside, always take
the master key with remote control with
you to ensure that you will remain able to
unlock the vehicle from the outside when-
ever the need arises.<
Hotel function
The hotel function locks the compartment
in the front center console and the luggage
compartment lid individually and discon-
nects them from the central locking sys-
tem. The spare key, refer to page 26, does not fit the lock for the hotel function. If you
then only hand over the spare key, e.g. in a
hotel, no access is possible to the luggage
compartment lid or to the compartment in
the front center console.
Turn the key to the right, refer to illustration,
and remove.
The hotel function is only activated after
subsequent locking or unlocking of the
vehicle. This locks the luggage compart-
ment lid and the compartment in the front
center console and disconnects them from
the central locking system.
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 con-
sole 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 set-
ting the hotel function again.<
Luggage compartment lid
Coupe: the luggage compartment lid
swings to the rear and upwards when
opened. Make sure there is sufficient free
space.<

Alarm system
The concept
The vehicle alarm system responds:
>When a door, the hood, or the luggage
compartment lid is opened
>To movement in the vehicle interior:
interior motion sensor
>To changing of the vehicle's tilt if some-
one attempts to steal the wheels or tow
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a
period of approx. 30 seconds
>The hazard warning flashers for approx.
5 minutes
>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 cor-
rectly armed by switching on the hazard
warning flashers for a single cycle and by
emitting an acoustic signal.
You can also open the luggage compart-
ment lid with the system armed using but-
ton on the remote control, refer to
page 28. When you close the lid, it is
secured again.
Switching off alarm
>Unlock the vehicle using the remote
control, refer to page 27
>or turn the ignition key to position 1.

Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes on locking:
door(s) or luggage compartment lid are
not completely closed. Even if you do
not close the alerted area, the system
begins to monitor the remaining areas,
and the indicator lamp flashes continu-
ously after approx.10 seconds. How-
ever, the interior motion sensor is not
activated
>The indicator lamp goes out on unlock-
ing: no manipulation or attempted intru-
sions have been detected in the period
since the system was armed
>The indicator lamp flashes on unlocking
before the remote control is inserted in
the ignition lock, but for no more than
roughly 5 minutes: an attempted entry
has been detected in the period since
the system was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Tilt alarm sensor and interior motion
sensor
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if some-
one attempts to steal the wheels or tow the
vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to
function properly, the windows and glass
roof 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 sen-
sor, is armed even if the convertible top is
open. Falling objects, e.g. leaves, can trig-
ger false alarms, refer to Avoiding uninten-
tional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. This is how you prevent unintentional
alarms, e.g. in the following situations:
>In garages with elevator ramps
>During transport on automobile trans-
port trains
>If animals are to remain in the vehicle.
Switching off tilt alarm sensor and
interior motion sensor
Press the button on the remote con-
trol 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 pre-
vent children from operating the windows
and injuring themselves etc.<

15 minutes
>In position 0 or with the ignition key
removed for approx. 1 minute, as long
as a door has not been opened.
To open, press the switch beyond the
resistance point.
When leaving the vehicle, remove the
master key with remote control and
close the doors, as otherwise children
could operate the windows and injure
themselves etc. operation mode at the door lock or with the
remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the closing force rises beyond a pre-
defined threshold during closing, the sys-
tem will immediately stop moving the win-
dow prior to lowering it slightly.
Convertible: the back windows and
rear window are not equipped with an
anti-trapping mechanism.<
Despite the anti-trapping mechanism,
you should always inspect the front
side window's travel path prior to closing it,
as the safety feature might fail to detect
certain kinds of obstructions, such as very
thin objects, and the window would con-
tinue 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 again pull the switch past the resis-
tance point and hold it in position within a
period of roughly 4 seconds, the anti-trap-
ping mechanism will be deactivated.<
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 con-
tact your BMW center for assistance.
Coupe:
Glass roof, electric with
raise function*
To prevent injuries, exercise care
when closing the glass roof 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 roof and injure
themselves etc.<

as a door has not been opened.
For information on using the convenience
operation mode at the door lock or with the
remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the glass roof encounters resistance
when closing from the raised position, the
closing action is interrupted and the glass
roof opens.
If the sliding panel encounters resistance
when closing within approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens approx. 8 in/20 cm.
Despite the anti-trapping mechanism,
you should always inspect the roof's
travel range prior to closing it, as the safety
feature might fail to detect certain kinds of
obstructions, such as very thin objects, and
the roof would continue closing.
The anti-trapping mechanism for closing
the glass roof is deactivated if the switch is
pressed beyond the resistance point and
held there. The closing action is immedi-
ately interrupted when you release the
switch.<
Following interruptions in electrical
power supply

Convertible: top
The fully automatic convertible top com-
bines secure weather protection with sim-
ple and convenient operation.
So that you get the maximum pleasure from
your convertible, here are a few tips:
>It is recommended that you close the
convertible top when the vehicle is
parked. The closed convertible top not
only protects the passenger compart-
ment against unforeseen weather dam-
age, it also represents a certain protec-
tion against theft. Nonetheless, even if
the convertible top is closed, only keep
valuables in the locked luggage com-
partment
>Do not attach luggage rack systems to
the convertible top
>At temperatures below 147/–106,
do not operate the convertible top, as
otherwise damage can occur.
Do not leave the soft top in the con-
vertible top compartment for longer
than one day when wet, as otherwise dam-
age from moisture can occur.
Do not place any objects on the convertible
top, as otherwise if the top was to be oper-
ated, they would fall off and lead to damage
or injury.
Never move the convertible top when the
rollover protection system is raised.
Driving without having completed the
opening or closing action can lead to dam-
age or injury.
Do not place hands in the top mechanism
during the opening and closing action.
Keep children away from the travel path of
the convertible top.
For safety reasons, only operate the con-
vertible top when the vehicle is at a stand-
still.<
If you have initiated top operation with
the vehicle at a standstill and then
drive off, e.g. at a traffic light, you can con-
tinue the initiated operation up to a speed
of 20 mph/30 km/h.
