For your own safety
Use unleaded gasoline only. Fuels
containing up to 10% ethanol or
other oxygenates with up to 2.8% oxy-
gen by weight (i.e., 15% MTBE or
3% methanol plus an equivalent
amount of co-solvent) will not void the
applicable warranties with respect to
defects in materials or workmanship.
Field experience has indicated signifi-
cant differences in fuel quality (i.e., vol-
atility, composition, additives, etc.)
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in drive-
ability, starting and stalling problems,
especially under certain environmental
conditions, such as high ambient tem-
perature and high altitude.
Should you encounter driveability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching to
a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Central locking system Door locks – outsideThe conceptThe central locking system is ready for
operation as soon as you close the
driver's door. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system can be
operated
>from outside via the driver's door or
luggage compartment lock and with
the remote control
>from inside via the central locking
button.
The fuel filler door remains unlocked
when you activate the system from in-
side the vehicle.
The anti-theft system is automatically
armed whenever you activate the cen-
tral locking system from outside the ve-
hicle. The alarm system is also acti-
vated or deactivated.
In the event of an accident, the central
locking system unlocks automatically
(only those doors which were not
locked separately with the safety lock
buttons). Refer to page 36. In addition,
the hazard warning flashers and interior
lamps come on.
To engage and release locksOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time unlocks
all of the remaining doors, the luggage
compartment lid and the fuel filler door.
When a door is opened, the inte-
rior lamps and the exterior door
handle illumination are switched on.
Switching off is automatic.< 380de015

transmitter to open and close the elec-
tric power windows and the sliding/tilt
sunroof.

Radio remote controlThe remote control makes opening and
locking the doors of your vehicle very
convenient. Furthermore, it provides
three additional functions which can
only be executed by means of the re-
mote control:
>Switching on the interior lamps and il-
luminating the exterior door handles.
With this function, you can also
"search for" your vehicle, when
parked in an underground garage, for
instance
>To open luggage compartment lid
The luggage compartment lid will
open slightly, regardless of whether
the lid was previously locked or un-
locked
>Panic Mode
In case of danger, you can trigger an
alarm.
The anti-theft system is also deacti-
vated/activated simultaneously with
the unlocking or locking of the vehicle,
and the alarm system is disarmed/
armed.
When the vehicle is unlocked, the inte-
rior lamps and the exterior door handle
illumination are switched on.
Master keysKeys with a transmitter for remote con-
trol are master keys. Refer to page 30.
Since children might be able to
lock the doors from the inside,
take the vehicle's keys with you so that
the vehicle can be opened again from
the outside at any time.<
Every transmission is indicated by a
light signal. If the signal no longer lights
up when a button is pressed and lock-
ing with the remote control no longer
functions:
Change the battery. Refer to page 168.380us644

dows and the sliding/tilt sunroof are

Alarm systemThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>To movement inside the vehicle (inte-
rior motion sensor)
>To variations in the vehicle tilt sensor
such as occur during attempts to
steal the wheels or tow the vehicle
>To interruption of battery voltage.
The system responds to unauthorized
vehicle entry and attempted theft by si-
multaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>The high beams flash on and off in
the same rhythm.
To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
by using a key or with the remote con-
trol, the alarm system is also simulta-
neously armed or disarmed.
The interior motion sensor is activated
approx. 30 seconds after you have fin-
ished locking the car.
The system indicates that it has been
correctly armed by switching on the
hazard flashers for a single cycle and by
emitting an acoustical signal.
When the system is active, you can still
gain access to the luggage compart-
ment by pressing button 3 on the re-
mote control transmitter. When the lid is
closed, it is armed once again.
Indicator lamp displays>The indicator lamp on the top of the
instrument panel flashes continu-
ously: The system is armed
>The indicator lamp flashes during
arming: door(s), the hood 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 continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated
>If the indicator lamp goes out when
the system is disarmed: No unau-
thorized entries have been detected
in the period since the system was
armed380de020

Alarm system>If the indicator lamp flashes for
10 seconds when the system is
disarmed: An attempted entry has
been detected in the period since the
system was armed.
Following triggering of an alarm, the in-
dicator lamp will flash continuously.Tilt alarm sensorThe tilt alarm sensor and interior motion
sensor may be switched off at the same
time. By doing this, you can prevent
false alarms on garage ramps or when
the vehicle is transported by trailer or
train, for instance.
Lock the vehicle twice (= arm the sys-
tem). In other words, press button 2 of
the remote control twice in succession
or lock the vehicle twice with the key.
The indicator lamp lights up briefly and
then flashes continuously. The tilt alarm
sensor and the interior motion sensor
are deactivated for as long as the sys-
tem remains armed.
Interior motion sensorThe transmitter and receiver of the inte-
rior motion sensor are located in a trim
panel in the vehicle's headliner.
In order for the interior motion sensor to
function properly, the windows and
sliding/tilt sunroof must be completely
closed.
Nevertheless, you should deactivate the
interior motion sensor whenever
>children or animals are left in the
vehicle
>the windows and/or sunroof are left
open.380de628
Emergency deactivation
procedureIf the car is locked and it is not possible
to disarm the system in the normal
manner, proceed as follows:
1 Use the key to unlock the door (the
alarm sounds for 30 seconds when
opening the door)
2 Turn the key to ignition key posi-
tion 1; the central locking system
unlocks the remaining doors.
The alarm system is now disarmed. Re-
fer the problem to your BMW center.
