Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system is designed to reduce
the susceptibility of the vehicle to theft
by making it impossible to start the en-
gine using any means other than the
special keys furnished with the vehicle.
Your BMW center can cancel the elec-
tronic system authorization for individ-
ual keys (in the event of loss, for in-
stance). A deactivated key can no
longer be used to start the engine.

463de042
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, simulta-
neously serving as a communications
interface designed to allow the security
system to maintain a continuous stream
of variable, 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 dam-
age the integrated electronic cir-
cuitry. A damaged key can no longer be
used to start the engine.<

Central locking system Door locks – from outside The conceptThe central locking system is ready for
operation whenever the driver's door is
closed. The system engages and re-
leases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
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 release handles remain
locked. The alarm system
* is also
armed or disarmed.
In the event of an accident, the central
locking system unlocks automatically.
In addition, the hazard warning flashers
and interior lamps come on.
Using the keyOne turn of the key in the door lock
opens only the driver's door, a second
turn of the key opens the passenger
door, the luggage compartment lid and
the fuel filler door.
You can have a confirmation mes-
sage set to inform you that the car
has been properly locked.<
You will find additional information on
the alarm system on page 42.460de006
Convenience operating modeYou can also operate the electric win-
dows and sliding/tilt sunroof via the
door lock.
>To open: With the door closed, turn
the key to the "Unlock" position and
hold it.
>To close: With the door closed, turn
the key to the "Lock" position and
hold it.
Watch during the closing process
to make sure that nobody is in-
jured accidentally. Letting go of the key
stops the operation. Turn the key all the way to the extreme
left or right to unlock/lock the door.

Door locks – from inside Use this button to operate the central
locking system when the doors are
closed. The doors and luggage com-
partment lid are unlocked or locked
only. The anti-theft alarm system is not
activated.
After opening the driver's door by acti-
vating the remote control once, the
front passenger door can also be
opened by pressing the button. When
the driver's door is closed, it is auto-
matically locked.
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 together with
the button for the central locking sys-
tem 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.
Doors locked from outside can be
opened from inside by first press-
ing the button and then pulling a re-
lease handle twice.<
To engage locks>Either use the central locking button
to lock all doors at once, or
>press down the individual door lock
buttons. The fuel filler door then re-
mains unlocked. As an added design
feature to prevent the driver from be-
ing inadvertently locked out of the ve-
hicle, the driver's door 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 rea-
son, take the vehicle's keys with you so
that the vehicle can be opened again
from the outside at any time.<

the illustration with the ignition key in
position 0 by pressing the button in the

tion key in position 1 or 2.462us005
Avoid engine speeds in the red warning
zone of the gauge.
To protect the engine, the engine man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power.462us017

Fuel gauge Temperature gauge When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
Once the indicator lamp begins to light
up continuously, there are still approx.
2.1 gallons (8 liters) of fuel in the fuel
tank.
Tank capacity: page 173.
If the tilt of the vehicle varies, e.g.,
when you are driving in mountainous
areas, this may cause the needle to
fluctuate slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<462us020
BlueThe engine is still cold. Drive at moder-
ate engine and vehicle speeds.RedWhen you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
If the lamp comes on while operating
the vehicle, the engine is overheated.
Switch the engine off immediately and
allow it to cool down.460de082
Between the blue and red zonesNormal operating range. It is not un-
usual for the needle to rise as far as the
edge of the red zone in response to high
outside temperatures or severe operat-
ing conditions.

Service Interval Display Remaining distance for serviceThe displays shown in the diagram
appear for a few seconds with the
ignition key in position 1 and 2 or for
a few seconds after starting the engine.
The next service due appears with the
message OILSERVICE or INSPECTION,
together with the remaining distance
before scheduled service.
The computer bases its calculations of
the remaining distance on the rate of
fuel consumption in the period immedi-
ately preceding your data request.
A flashing message and a "–" in front of
the number mean that the service inter-
val has already been exceeded by the
distance shown on the display. Please
contact your authorized BMW center for
an appointment.462us022

(6/7) for the outside temperature dis-
play by pressing the right-hand reset
button in the instrument cluster when
the temperature display is active.462us023
Ice warning If the outside temperature sinks to
approx. 37.57 (+ 36), a warning sig-
nal sounds and the display flashes
briefly.
The warning is repeated whenever the
temperature goes to at least 437
(+ 66) and then drops again to 37.57
(+ 36).
The ice warning does not alter the
fact that surface ice can form at
temperatures above 37.57 (+ 36),
e. g. on bridges or shaded road sur-
faces.<
Average fuel consumption If you continue to hold the button on the
turn signal lever, the average fuel con-
sumption last displayed is recalculated
from that point in time.462us007
