Keys1 The master keys with remote control
determine the functions for the Key
Memory, refer to page 60
There is an extended-life battery
in every master key that is
charged automatically in the steering
lock as you drive.
If you have a master key that is not
being used, use that key at least once a
year by driving with it for an extended
period to recharge the battery. Refer
also to page 35.<
2 Keep your spare key in a safe place,
such as in your wallet. This key is not
intended for continuous use 46cde059
3 Door and ignition key
The locks for the luggage compart-
ment lid and the glove compartment
cannot be operated with this key –
this is recommended for valet park-
ing, for instance.
Replacement keysReplacement keys are available exclu-
sively through your BMW center. Since
the keys are part of a security system,
vehicle ownership must be checked
before a replacement key can be issued
(refer to "Electronic Vehicle Immobi-
lizer" on page 33).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your re-
placement key. After getting a replace-
ment key, turn it to position 2 in the
ignition lock once (ignition switched on)
and then back. This allows the passive
anti-theft system to "learn" the new
key.<

Electronic vehicle immobilizer The key to securityYour BMW is equipped with a passive
anti-theft system. This electronic immo-
bilization system reduces the likelihood
of your vehicle being stolen by making
it impossible to start the engine using
any keys other than the ones furnished
with the vehicle. Your BMW center can
cancel the electronic system authoriza-
tion for individual keys (in the event of
loss, for instance). A deactivated key
can no longer be used to start the en-
gine.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. While the
engine is running, the circuitry in the
ignition key and the vehicle's electronic
system constantly exchange variable,
vehicle-specific signals. The system will
not release the ignition, fuel injection
and starter unless it recognizes 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.<

Opening and closing – from outsideUsing the remote control The remote control gives you an excep-
tionally convenient method for unlock-
ing and locking your vehicle. Further-
more, it provides two additional func-
tions that only the remote control can
execute:
>Switching on the interior lamps
Using this function, you can also
"search" for your vehicle e. g. when-
ever it is parked in an underground
garage
>Opening the luggage compartment
lid
It will open slightly, regardless of
whether it was previously locked
or unlocked.
When you unlock the vehicle, the anti-
theft system is deactivated, the alarm
system
* is disarmed, and the interior
lamps are turned on. When you lock the
vehicle, the systems are activated and
armed, and the lamps go off.
You can have a signal set as an
acknowledgement message that
the vehicle is closed correctly.<
Master keysKeys with remote control are master
keys. Refer to page 32.
Children might be able to lock the
doors from the inside. For this rea-
son, always take the vehicle keys with
you so that the vehicle can be opened
again from the outside at any time.<46cde020
Master keys that are used repeat-
edly are always ready for opera-
tion since the battery in the key is
charged automatically in the steering
lock as you drive.
If it is no longer possible to lock the
vehicle via the remote control, the
battery is drained. Use this key while
driving for an extended period in order
to recharge the battery. Refer also to
page 32.
To prevent unauthorized use of the
remote control, surrender only the door
and ignition key or the spare key (refer
to page 32) when leaving the vehicle for
valet parking, for example.
In the event of a system malfunction,
please contact your BMW center.
You can also obtain replacement keys
there.<

Luggage compartment lid The lock Only the master keys (refer to page 32)
fit in the lock of the luggage compart-
ment lid.To secure separatelyLock the glove compartment with a
master key.
This locks the luggage compartment lid
and disconnects it from the central
locking system. If you then surrender
only the door and ignition key (refer to
page 32), access to the vehicle through
the luggage compartment is not possi-
ble, which is an advantage when using
for valet parking, for instance.46cde001

not been locked separately, you can
open it with this button in the footwell
on the driver's side when the vehicle
is stationary.460de011

Alarm system
*
The conceptThe vehicle alarm system responds:
>When a door, the hood or the lug-
gage compartment lid is opened
>Movements inside the vehicle
>To a change in the vehicle's tilt –
if someone attempts to steal the
wheels or tow the vehicle without
authorization, for example
>If there is an interruption of battery
voltage.
The system responds to unauthorized
vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>Activating the hazard warning
flashers for approx. five minutes
>Flashing the high beams on and off in
tandem with the hazard warning
flashers.
To activate and deactivate the
alarm systemWhen the vehicle is locked or unlocked
by using a key or the remote control,
the alarm system is also armed or dis-
armed at the same time.
The interior protection and tilt sensor
alarm systems are activated approx.
30 seconds after you have shut the last
door.
If the alarm system has been armed
correctly, the hazard warning flashers
flash once.
You can have one signal set as
acknowledgment when arming
and disarming.<
You can also open the luggage com-
partment lid when the system is armed
by pressing button 3 of the remote con-
trol (refer to page 37). When it is closed,
the lid is once again secured.
Indicator lamp displaysThe indicator lamp is located under the
inside rearview mirror.
>When the indicator lamp flashes con-
tinuously, the system is armed>The indicator lamp flashes when it
is armed. Doors, the hood or luggage
compartment lid are not closed
properly. Even if you do not close the
alerted area, the remaining areas are
deadlocked, and the indicator lamp
flashes continuously after 10 seconds.
However, the interior protection
system is not activated>If the indicator lamp goes out when
the system is disarmed, no manipula-
tion or attempted intrusions have
been detected in the period since the
system was armed46cus033

Do not select a memory position
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected seat movement.<
Your BMW center can adjust your
vehicle's systems in such a man-
ner that your personalized settings are
automatically set for the seat, head
restraint and outside mirror positions
when you unlock the vehicle with your
personal remote control.<
If you make use of this method of
adjustment, be sure that the foot-
well behind the driver's seat is unob-
structed before unlocking the vehicle.
If you fail to do so, any persons or ob-
jects behind the seat could be injured
or damaged by a rearward movement
of the seat.<

Child restraints
*
Commercially-available child restraint
systems are designed to be secured
with a lap belt or with the lap belt por-
tion of a combination lap/shoulder belt.
Improperly or inadequately installed
restraint systems can increase the risk
of injury to children. Always read and
follow the instructions that come with
the system.
If you use a child restraint system with
a tether strap, two additional tether an-
chorage points (refer to the arrows in
the illustration) have been provided.
Depending on the location selected for
seating in the rear passenger area, at-
tach the tether strap to the correspond-
ing anchorage point to secure the child
restraint system.46cus001
If the respective seating position is fit-
ted with a headrest lift the headrest and
pass the tether strap between the
headrest and the seat back.
Adjust the tether strap according to the
child restraint manufacturer's instruc-
tions.
Before installing any child restraint
device or child seat, please read
the following:
Never install a rear-facing child restraint
system in the front passenger seat of
this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rear-facing child restraint sys-
tem (of the kind designed for infants
under 1 year and 20 Ibs./9 kg) would be
within the airbag's deployment range,
you should never mount such a device
in the front passenger seat, since the
impact of the airbag against the child
restraint's backrest could lead to seri-
ous or fatal injuries.
If it is necessary for a child (not an in-
fant) to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the
airbag and the child. Older children
should be tightly secured with a safety
belt. Younger children should be se-
cured in an appropriate forward-facing
child restraint system that has first been
properly secured with a safety belt.
Never install a rear-facing child restraint
system in the front passenger seat.
We strongly urge you to carefully read
and comply with the instructions for in-
stallation and use provided by the child
restraint's manufacturer whenever you
use such a device.
Be sure that all occupants (of all ages)
remain properly and securely restrained
at all times.<
All rear seating positions in your vehicle
meet the recommendations of SAE
J1819, an industry-recommended prac-
tice for securing child restraint systems
in motor vehicles.
