firm that the vehicle's locks have
engaged securely. Persons or animals inside the
vehicle may be able to lock the
doors from the inside. For this reason,
always take the vehicle keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery. To pre-
vent unauthorized use of the remote
control, surrender only the spare key
when leaving the vehicle for valet park-
ing, for example.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

Alarm system*The conceptThe vehicle alarm system responds:
>When a door, the hood, the tailgate
or the rear window is opened
>To movement inside the vehicle –
interior motion sensor
>To variations in the vehicle's tilt angle
such as those occurring 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
simultaneously activating the following:
>Sounding an acoustic alarm for
30 seconds
>The hazard warning flashers are acti-
vated for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm
systemWhen the vehicle is locked or unlocked
via the driver's door lock or with the
remote control, the alarm system is also
simultaneously armed or disarmed.You can have different acknowl-
edgment signals set to confirm
arming and disarming.<
You can also open the rear window
when the system is armed by pressing
the remote control button, refer to
page 32. The window is once again
secured when it is closed.
Extended pressure on the button sets
off the alarm – Panic mode, refer to

close the alerted area(s), the remain-
ing areas are secured, and the indi-
cator lamp will flash continuously
after 10 seconds. However, the inte-
rior motion sensor is not activated

Transporting children safelyCommercially 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.Correct location for installingIn your BMW, all seats equipped with a
three-point safety belt – except for the
driver's seat – are suitable for installing
universal child-restraint systems of all
age classes and which have been
approved for the age group in question.
Child-restraint system with
tether strapIf you use a child-restraint system with
a tether strap, three additional tether
anchorage points have been provided.
To gain access to this anchor fitting lift
the plastic plug with the help of a
screwdriver.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corre-
sponding anchorage point to secure the
child-restraint system, as shown in the
illustration.
If the respective seating position is fit-
ted with a head restraint lift the head
restraint and pass the tether strap
between the head restraint and the seat
back.
It is recommended to readjust the head
restraint in the lowest possible position.
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 rearward-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 rearward-facing child-restraint
system – of the kind designed for
infants under 1 year and 20 lbs/9 kg –
would be within the airbag's deploy-
ment 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 serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the instrument panel as possible.
This important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
should be tightly secured with a safety
belt after they have outgrown a booster
seat that is appropriate for their age,
height, and weight. Younger children
should be secured in an appropriate
forward-facing child-restraint system
that has first been properly secured
with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child-restraint's manufacturer whenever
you use such a device. Do not attempt
to modify child-restraint systems. If you
do this, the protection provided by
these systems could be impaired.
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
SAEJ1819, an industry-recommended
practice for securing child-restraint sys-
tems in motor vehicles.
Securing child-restraint systemAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have often reflected on
how great it would be if you could per-
manently configure your vehicle's vari-
ous features and adjustments to mirror
your own personal preferences. In engi-
neering your vehicle, BMW has
included a number of options for stor-
ing personal adjustment data. These
can be programmed at your BMW cen-
ter.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system relies on a bilateral data
exchange to identify the individual user
and executes the selected settings
whenever the remote control unit is
used to disengage the locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish the differ-
ent keys with their individual settings.What the system can doYou can learn about the entire array of
features this system offers at your BMW
center. Here are just a few examples:
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<

ing lamps, refer to page 93
>Sets the units of measure for display-
ing time, outside temperature, dis-
tance traveled and fuel consumption
in the instrument cluster
>When you shift into Reverse, an
acoustic signal indicates that PDC
has been activated, refer to page 85
>Switches on rear window defroster
automatically, to pages 98, 103
>Activates/deactivates various alarm
system functions, refer to page 39
>After giving an ice warning, the
