Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
antiÐtheft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the vehicle to theft
by making it impossible to start the
engine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for indi-
vidual keys (in the event of loss, for
instance). A deactivated key can no
longer be used to start the engine.46cde060
How the electronics workAt the heart of this system is an elec-
tronic chip that is integrated into the
key. The lock mechanism itself is actu-
ally a dual-function device, serving as a
communications interface designed to
allow the vehicle's electronics system
to maintain a continuous stream of vari-
able, vehicle-specific signals with the
electronic circuitry in the key. The
system will not release the ignition, fuel
injection and starter unless it recog-
nizes an "authorized" key.
Force applied to the key can
damage the integrated electronic
circuitry. A damaged key can no longer
be used to start the engine.<

Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for
operation whenever the driver's door
is closed. The system engages and
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door at the same time.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside by pressing a button.
Activating it from inside does not lock
the fuel filler door (see page 38). When
the system is actuated from the
outside, the anti-theft system is acti-
vated simultaneously. Both the door
locks and the safety lock buttons
remain locked. The alarm system is also
armed or disarmed.
The central locking system unlocks
automatically in the event of an acci-
dent. In addition, the hazard warning
flashers and interior lamps come on.
Using the keyOne turn of the key in the driver's door
lock unlocks the driver's door only.
Turning the key a second time will
unlock the passenger-side door, the
luggage compartment lid and the fuel
filler door.
You can have a signal set as an
acknowledgment message that
the vehicle is closed correctly.<460de006
Convenience operationYou can also operate the power
windows and sliding/tilt sunroof from
the door lock.
>To open: with the door closed, hold
the key in the "Unlock" position.
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to be sure that no one is injured.
Releasing the key stops the operation. Turn the key to the extreme left or right
to unlock/lock the door.

Opening and closing Ð from the inside Use this button to operate the central
locking system whenever the doors are
closed. The doors and luggage
compartment lid are unlocked or locked
only. The anti-theft alarm system is not
activated.
If only the driver's door was
unlocked from the outside and you
press the button, then the passenger-
side door, the luggage compartment lid
and the fuel filler door will unlock if the
driver's door is open.
The driver's door will be locked if it is
closed.<
If you desire, the central locking
system will secure the locks as
soon as you start to drive. This can be
adjusted to be key-specific.<460us007
To unlock and open the doors>Either unlock the doors at the same
time using the button for the central
locking system and then pull each of
the release handles above the
armrests,
or
>pull the release handle for each door
twice: the first pull unlocks the door,
and the second one opens it.
To engage the locks>Either use the central locking button
to lock both doors at once,
or
>press the individual safety lock
buttons down. As an added design
feature to prevent the driver from
being inadvertently locked out of the
vehicle, the driver's door safety lock
button will not engage as long as the
door is open.
Children might be able to lock the
doors from the inside. For this
reason, take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<

Fuel gauge Temperature gauge Service Interval Display When you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
Once the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel remaining in
the fuel tank.
For fuel tank capacity, refer to page 187.
If the tilt of the vehicle varies (extended
driving in mountainous areas, for
example), there may be slight fluctua-
tions of the needle.
Fill the fuel tank well before it is
empty. Driving to the last drop of
fuel can result in damage to the engine
and/or the catalytic converter.<462us020
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on while operating
the vehicle: the engine is overheated.
Stop and switch the engine off immedi-
ately and allow it to cool down.Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response to
high outside temperatures or severe
operating conditions. Checking coolant
level: refer to page 137.460de082
Remaining distance for serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the distance remaining
before the next scheduled service.
The computer bases its calculations of
the remaining distance on the previous
driving style.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.46cus006
