MirrorsPassenger-side exterior mirror tilt
function(automatic curb monitor)
>Move the mirror selector switch 1 to
the "driver's mirror" position
>When the selector lever is placed in
"Reverse," the passenger-side mirror
tilts downward. This brings e. g. the
lower area adjacent to the vehicle
(curbs, etc.) into the driver's field of
vision while parking.
You can deactivate this automatic
feature by setting the mirror selector
switch to the "passenger side" position.
Interior rearview mirror with
automatic dimming featureThis mirror automatically dims through
an infinitely variable range and switches
automatically to its clear, undimmed
mode whenever you engage reverse
gear.
There are two photocells for automatic
dimming. One photocell (arrow) is posi-
tioned in the mirror's frame, while the
other is slightly offset on the opposite
side of the mirror.
For the mirror to function perfectly,
keep the photocells clean and the area
between the inside rearview mirror and
the windshield free of any obstruction,
like stickers, etc.

Airbags 1 Front airbags on the driver and
passenger sides
2 Side airbags on the driver and
passenger sides (front and rear
*)
Protective effectThe front airbags protect the driver and
passenger in the event of a head-on
collision where the protection provided
by the safety belt alone would not be
adequate. The side airbags help
provide protection in the event of a
collision from the side. Each of the side
airbags is designed to help support the
seat occupant's upper body.
The side airbags in the rear
passenger area
* of your vehicle
may already have been deactivated
either at the time of manufacture or by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
For information on the correct sitting
position, refer to page 44.
The airbags will not be triggered in
the event of a minor accident, a
vehicle rollover, or collisions from the
rear.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not attempt to remove the
airbag restraint system from the
vehicle. In the event of a malfunction,
deactivation, or triggered actuation (as
a response to an accident) of the airbag
restraint system, consult your BMW
center for checking, repairs or removal.
Modifications may not be made on
either the wiring or the individual
components in the airbag system. This
includes the padded steering wheel
hub, the instrument panel, the side trim
panels of the front or rear doors and the
roof pillars or the sides of the front
headliner. Do not attempt to remove or
dismantle the steering wheel. To ensure
compliance with official safety regula-
tions, entrust disposal of airbag genera-
tors to a BMW center. Unprofessional
attempts to service the system could
lead to failure in an emergency or
undesired airbag activation, either of
which could result in personal injury. Do
not touch the individual components
directly after the system has been trig-
gered, as otherwise there is a danger of
burns.<

Airbags
At all times, occupants should sit
upright and be properly restrained
(infants and small children in appro-
priate child-restraint systems; larger
children and adults using the safety
belts). Never let an occupant's head
rest near or on a side airbag because
the inflating airbag could cause a
serious or fatal injury. Please note that
the word "Airbag" imprinted on the door
trim panel indicates the airbag's loca-
tion.
Accident research shows that the
safest place for children in an
automobile is in the rear seat. However,
a child sitting in the rear seat and not
properly restrained may place his or her
head on or near the side airbag, if so
equipped. For example, a child Ð even
though belted Ð may fall asleep with his
or her head against the side airbag. It
may be difficult for a driver to ensure
that children in the rear seat will remain
properly positioned at all times and not
place their heads on or near the side
airbag. Therefore, we recommend that
the rear seat side airbags, if provided,
be deactivated if you plan to transport
children in the rear seat.
The rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW
center. Labels in the rear door opening
should indicate the status of your rear
seat side airbags. If you are uncertain of
their status, or wish to have the airbags
activated or deactivated, please
contact your BMW center.<
Even when all these guidelines are
observed, there is still a small residual
risk of injuries to the face, hands and
arms occurring from airbag deployment
in isolated instances. The ignition and
inflation noise may provoke a mild
temporary hearing loss in extremely
sensitive individuals.
Airbag warning information is also
provided on the sun visors. This is the right way a child should sit in
a child-restraint device when rear side
airbags (arrow) are provided.

Transporting children safely
This is the right way a larger child
should sit wearing the safety belt when
rear side airbags (arrow) are provided.
Operational status
The indicator lamp in the instru-
ment cluster shows the airbag
system status starting in ignition
key position 1.
System operational:
>The indicator lamp comes on briefly,
when the ignition key is turned into
position 1 or 2
System malfunction:
>The indicator lamp fails to come on,
when the ignition key is turned
>The indicator lamp fails to go out
after the engine has been started, or
it comes on during normal driving.
Please respond to any malfunctions in
the system by immediately having it
inspected at your BMW center; other-
wise the airbag could fail to respond to
an accident in which both the angle and
the severity of the impact would
normally trigger airbag deployment.
Commercially available child seats
complying with the legal standard are
designed to be secured with a lap belt
or with the lap belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint systems
can increase the risk of injury to chil-
dren. Always read and follow the
instructions that come with the system.

Transporting children safelyIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points (refer to the arrows in
the illustration) have been provided.
They are located under the convertible
top compartment lid. Depending on the
location selected for seating in the rear
passenger area, attach the tether strap
to the corresponding anchorage point
to secure the child-restraint system.
Lift the respective head restraint and
pass the tether strap between the head
restraint 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 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 20-30 lbs/9-14 kg)
would be within the airbag's deploy-
ment range, you should never mount
such a device in the front passenger
seat, as the impact of the airbag against
the child restraint's backrest could lead
to serious or fatal injuries. If it is neces-
sary 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
airbag and the child. Older children
should be tightly secured with the
safety belt.
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 when-
ever you use such a device.
Always ensure that all occupants (of all
ages) remain properly and securely
restrained at all times.c
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.

Transporting children safelyLATCH child-restraint system
installationThe anchorage points for the LATCH
child-restraint system installation are
located behind the upholstery at the
positions indicated by the arrows.
Carefully slide the brackets through the
gaps in the upholstery at the indicated
locations.
Always follow all manufacturer's
instructions and observe all safety
precautions when installing the LATCH
child-restraint system.
Leave the rear safety belts in the
holders, if they are not needed, to avoid
unwanted movement from the safety
belts at high speeds.<
To prevent damage to the upholstery,
you can purchase an insertion aid
*
(funnel) from your BMW center.
Firmly press the insertion aid into the
gap between the seat cushion and
backrest, continuing until the two
guides snap into place on the LATCH
brackets in the seat.

Transporting children safelyChild seat securityAll 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.
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.
The belt cannot be extracted further.
Always observe the installation instruc-
tions provided by the manufacturer of
the child-restraint system.Unlock the safety beltRelease the safety belt, remove the
child's seat and retract the safety belt
to its end position on the belt retractor.

Rollover protection system In the event of an accident or some
other critical driving situation (extreme
tilting in the longitudinal or transverse
axis, loss of contact with the ground),
the rollover protection system will be
automatically activated. The protective
bars located in the rear head restraints
extend within fractions of a second.
In addition to the integrated rollover bar
in the windshield frame, the rollover
protection system affords all the vehicle
occupants necessary headroom.
Always keep the travel path for the
rollover protection system free
and clear. Under no circumstances
should you cover the head restraints.
In the event of less serious accidents,
the safety belt will protect you and,
depending on the severity of the acci-
dent, so will the safety belt tensioner
and the multi-stage airbag restraint
system as well.<
If, after being automatically triggered,
the protective function is not needed,
then the rollover protection system can
be lowered back into place. No special
tool is needed for this.
1. Using a screwdriver from the on-
board tool kit, remove the cover
panel; to do this, position the screw-
driver under the notch (arrow)
2. Pull up on the lever (arrow) toward
the front of the vehicle and keep it in
this position

tive bar 1 from on top until you hear it
click into place
4. Put the cover panel back in place
and press down firmly
5. Press the rear part of the head
restraint 2 closed.
Do the same for the second protective
bar. If you are not familiar with any of
the procedures, consult your BMW
center.
Have the rollover protection system
checked out by your BMW center after
it has been inadvertently triggered.Do not move the convertible top
under any circumstances if the
rollover protection system has
extended.
Do not use the rear head restraints as
storage shelves.
Absolutely no modifications are to be
made to any of the rollover protection
system's individual components or any
of its wiring.
Only your BMW center is to carry out
any work on the rollover protection
system.
Work done on the system that is carried
out improperly could lead to failure in
an emergency or accidental airbag acti-
vation.
Regarding having the system checked
to ensure long-term operation: be scru-
pulous in adhering to the Service
Interval Display for maintenance inter-
vals. Every 2 years at the latest, the roll-
over protection system must be
inspected by a BMW center.<

Vehicle Memory, Key Memory How the system functionsYou have probably frequently wished
that you could configure individual
functions of your vehicles to reflect your
own personal requirements. In engi-
neering your vehicle, BMW has
included several user-defined func-
tions in the vehicle's design. Your BMW
center can make these settings for you
in accordance with your wishes.
There are settings related to the vehicle
("Vehicle Memory") and settings related
to individuals ("Key Memory"). You can
have up to four different basic settings
adjusted for four different persons. The
only requirement is that each person
uses his or her own remote control key.
When your vehicle is unlocked with the
remote control, the vehicle recognizes
the individual user by means of a data
exchange with the key, and makes
adjustments accordingly.
In order for you to distinguish between
different keys, colored decals are
supplied together with the keys.What the system can doYour BMW center can provide you with
details on the possibilities that the
Vehicle and Key Memory systems offer.
Examples for Vehicle Memory:
>Various signals that can serve as
acknowledgment for locking and
unlocking the vehicle, refer to
pages 29, 30
>Activating/deactivating operation of
"Follow me home," refer to page 85.Examples for Key Memory:
>Locking the vehicle after driving off,
refer to page 33
>Automatically moving the seat and
outside mirror into position for that
particular person when unlocking the
vehicle, refer to page 49
>Calling up customized settings for the
automatic climate control when
unlocking using the remote control,
refer to page 92
>After the engine is started, calling up
of the last selected driving program
for each shifting mode, refer to
page 68.
You will see this symbol
throughout the Owner's Manual. It
is to remind you at appropriate places
of the settings that are available to
you.<
