Central locking system
The concept
The central locking system is ready for
operation whenever the driver's door is
closed. This simultaneously engages and
releases the locks on the following:
>Doors
>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the driver's door lock
>with Comfort Access via the door han-
dle
and from inside via the button for the cen-
tral locking system.
When the system is locked from inside, the
fuel filler door remains unlocked, refer to
page 36.
The anti-theft system is automatically acti-
vated whenever you activate the central
locking system from outside the vehicle.
The alarm system is armed/disarmed at the
same time.
In an accident, the central locking system
automatically unlocks the vehicle. In addi-
tion, the hazard warning flashers and inte-
rior lamps switch on.
Opening and closing:
from outside
Using the remote control
When you engage/release the vehicle's
locks, you simultaneously activate/deacti-
vate the anti-theft system, arm/disarm the
alarm system
and switch the interior lamps
on/off. In addition, the remote control offers you
another function:
>Panic mode
In case of danger, you can trigger an
alarm.
You can have various confirmation
signals programmed into the system
to verify that the vehicle has been locked
securely.<

Because any persons or animals left
unattended in a parked vehicle could
lock the doors from the inside, you should
always keep the remote control with you;
this precaution ensures that you will remain
able to unlock the vehicle from the outside
at all times.<
When it is no longer possible to lock
the vehicle via the remote control, the
battery is discharged. Use this remote con-
trol during an extended drive; this will
recharge the battery, refer to page 32.
In the event of a system malfunction,
please contact your BMW center, which is
also your source for replacement keys.<

To avoid injuries, be sure that the
travel path of the luggage compart-
ment lid is clear when it is closed, as with
all closing procedures.
Operate the vehicle only when the luggage
compartment lid is completely closed.
Otherwise, exhaust fumes could penetrate
the interior of the vehicle. If special circum-
stances should make it absolutely neces-
sary to operate the vehicle with the luggage
compartment lid open:
>Close all windows and the glass roof
>Adjust the automatic climate control's
blower to supply a high rate of airflow,
refer to page 104.<

Use the key to unlock the luggage com-
partment lid, refer to page 37, and then
slowly open or close it, taking care to avoid
abrupt motion in the process.
Emergency release

ment lid from inside the luggage compart-
ment.
Luggage compartment
Net*
You can use the net to store smaller
objects on the bulkhead separating the lug-
gage compartment from the rear seats.
Do not stow objects behind the side
trim panels on the left and right in the
luggage compartment, as otherwise the
electrical parts could overheat and be
damaged.<
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

Opening and closing
40 >To a change in 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.
five minutes
>The high beams, which flash on and off
in the same rhythm.
Arming and disarming the alarm
system
When you lock or unlock the vehicle, either
with the remote control unit or at the door
lock, the alarm system is armed or dis-
armed 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 have different acknowledg-
ment signals set to confirm arming
and disarming.<
You can also open the luggage compart-
ment lid with the system armed using
button 3 on the remote control, refer to
page 34. When you close the lid, the sys-
tem is rearmed.
Pressing the Panic mode button for a
longer period triggers the alarm, refer
to page 34.<
To deactivate the alarm
>unlock the vehicle using the remote
control, refer to page 34
>insert the remote control all the way into
the ignition lock, engaging the detent.
Indicator lamp displays
>The indicator lamp below the interior
rearview mirror flashes continuously:
the system is armed
>The indicator lamp flashes when the
system is armed: door(s), the hood or
luggage compartment lid are not com-
pletely closed. Even if you do not close
the alerted area, the system begins to
monitor the remaining areas, and the
indicator lamp flashes continuously
after 10 seconds. However, the interior
motion sensor is not activated
>The indicator lamp goes out when the
system is disarmed: no manipulation
or attempted intrusions have been
detected in the period since the system
was armed
>The indicator lamp flashes when you
disarm the system before the remote
control unit 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.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion
sensor may be switched off at the same
time. You can do this to prevent a false
alarm from being triggered in garages with
elevator ramps, for instance, or when the
vehicle is transported by trailer or train:
Lock, i.e. arm twice; press button 2
on the remote control twice in succession,
refer to page 34.
The indicator lamp lights up briefly and

then flashes continuously. The tilt alarm
sensor and the interior motion sensor are
switched off as long as the system is
armed.
If you desire, the
>tilt alarm sensor
>interior motion sensor
can be switched off permanently. Please
contact your BMW center for assistance.<
Interior motion sensor
In order for the interior motion sensor to
function properly, the windows and glass
roof must be completely closed.
Be sure to deactivate the interior motion
sensor, refer to section on Avoiding unin-
tentional alarms, when you wish to leave
the windows or glass roof open.
Windows
Opening and closing windows
From radio mode on:
>Press the switch until you feel resis-
tance:
The window continues to move down-
ward as long as you continue to hold
the switch
>Briefly press the switch beyond the
resistance point:
The window moves downward auto-
matically. Briefly press the switch again
to stop the opening movement.
You can close the windows in the same
manner by pulling the switch.
After switching off the ignition
You can still operate the power windows:
>For approx. 15 minutes with the remote
control unit in the radio mode
>For approx. 1 minute in position 0 or
with the remote control unit disen-
gaged.
To open, press the switch beyond the
resistance point.
When leaving the vehicle parked,
always remove the remote control
from the ignition lock and close the doors;
this precaution prevents children from
operating the power windows and injuring
themselves, etc.<
For information on using the convenience
operation mode at the door lock or with the
remote control, refer to page 34 or 36.
Safety feature
If the force rises beyond a predefined
threshold during closing, the system will
stop moving the window prior to lowering it
slightly.
Despite this safety feature you should
always inspect the window's travel
path prior to closing it, as the safety system
might fail to detect certain kinds of obstruc-
tions, 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 safety feature. Under these conditions
the window will respond to forces beyond a
defined threshold by only opening several
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 safety fea-
ture will be deactivated.<
When you close the windows they will
slow down as they approach the end
of their travel; this is to allow the safety fea-
ture to respond more precisely to any
obstructions encountered in this critical
range.<

Signaling briefly
Press the lever up to but not beyond the
resistance point. It then returns to the cen-
ter position when released.
If the flashing of the indicator lamp and the
ticking from the relay are both faster than
normal, this indicates that one of the bulbs
is defective; if a trailer is attached, this
could also indicate that one of its turn sig-
nal indicator bulbs is defective.
