61 Passenger safety systems
Airbags1Front airbags on the driver and pas-
senger sides
2Side airbags on the driver and pas-
senger sides front and rear*Protective effectThe front airbags supplement the safety
belts by providing additional protection
in the event of a severe frontal collision
in which the protection afforded by the
belts alone may no longer be sufficient.
The side airbags help provide protec-
tion 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.
For information on the correct sitting
posture, refer to page 52.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated either at
the time of manufacture or by a BMW
center. You may have them activated if
you desire to do so. Please contact
your BMW center for additional infor-
mation.<
The airbags do not deploy in
response to minor collisions, rear
impacts and certain kinds of vehicle
rollover.<
Do not apply adhesive materials to
the cover panels of the airbags,
cover them or modify them in any other
way. Do not remove the airbag restraint
system. In the event of a malfunction,
deactivation or triggered activation – as
a response to an accident – of the air-
bag restraint system, consult your BMW
center for inspection, repair or disas-
sembly. Do not modify or tamper with
either the wiring or the individual com-
ponents in the airbag system. These
include the upholstered covers on the
steering wheel, instrument panel, side
trim panels of the doors and front roof
pillars and on the sides of the headliner.
Also, do not attempt to remove the
steering wheel. 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
immediately after the system has been
activated, as this could result in per-
sonal injury.<
At all times, occupants should sit
upright and be properly restrained
– infants and small children in appropri-
ate child-restraint systems; larger chil-
dren 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 indi-
cates the airbag's location.
Accident research shows that the saf-
est place for children in an automobile
is in the rear seat. However, a child sit-
ting in the rear seat and not properly
restrained could place his or her head
on or near the airbag, if so equipped.
For example, a child — even though
belted in — 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 installed in
the vehicle, be deactivated if children
will travel in the rear seat.
The rear-seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW cen-
ter. Labels in the 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 con-
tact your BMW center.<
Even when all these guidelines are fol-
lowed, 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
induce a mild temporary hearing loss in
sensitive individuals.
Corresponding airbag warning labels
are located on both sun visors.This is the right way a child should sit in
a child-restraint when rear side airbags,
see arrow, are provided.
This is the right way a larger child
should sit wearing the seat belt when
rear side airbags, see arrow, are pro-
vided.Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system when the ignition key is
in position 1 or higher.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or higher.
System malfunction:
>Indicator lamp does not come on or
>indicator lamp lights up continuously.

If there is a system malfunction, there is
a risk that the airbags will not be trig-
gered within their normal response
range, even if the level of impact would
normally have triggered them.
Have your BMW center inspect the sys-
tem immediately.
Transporting children safely
To avoid undesired movement at
high speeds, always store the rear
safety belts in their retainers when they
are not in use.<
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.
Child-restraint system with
tether strapIf you use a child-restraint system with
a tether strap, two additional tether
anchorage points have been provided –
refer to the arrows in the illustration.

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.
1. Open the convertible top compart-
ment lid, refer to page 41 or 46
2. Lift the headrest and pass the tether
strap between the headrest and the
seat back. It is recommended that
you return the headrest to its lowest
possible position
3. Adjust the tether strap according to
the child-restraint manufacturer's
instructions
4. Close the convertible top compart-
ment panel.
It is recommended to cover the child-
restraint attaching clip with a soft mate-
rial to prevent damage to the stored
soft top.
Should a hard top be installed, the
fitting of child harness tether
strap/s – if child seat is required – is
necessary before installation of the
hard top.<
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 lbs/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 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 dashboard 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 the
safety belt after they have outgrown a
booster seat that is appropriate for their
age, height, and weight. Younger chil-

dren should be secured in an appropri-
ate forward-facing child-restraint sys-
tem that has first been properly
installed 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
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
SAE J1819, 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
is located in the immediate vicinity of
the buckle 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.
The belt cannot be extracted further.
Always observe the installation instruc-
tions provided by the manufacturer of
the child-restraint system.To unlock the safety belt Release the safety belt, remove the
child seat and retract the safety belt to
its end position on the belt retractor.

LATCH child-restraint mounting
systemLATCH: Lower Anchors and Tethers for
CHildren
Canadian models only:
The LATCH anchorage points are iden-
tified by buttons.
The left and right rear seats are both
equipped with a LATCH child-restraint
mounting system.
The anchorage points for the LATCH
child-restraint system 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 mounting system.
To avoid undesired movement at high
speeds, always store the rear safety
belts in their retainers when they are
not in use.<
Your BMW center can provide you with
a special installation aid* that helps pre-
vent damage to the upholstery.
Press the installation aid firmly in the
crack between the seat and the back-
rest upholstery until both funnels click
onto the LATCH system bars in the
seat.
The illustration is an example showing
the anchorages for a LATCH child seat
system on the right rear seat.

Rollover protection systemIn 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 sys-
tem as well.<
If, after being automatically triggered,
its 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 – see arrow
2. Pull up on the lever – see arrow –
toward the front of the vehicle and
keep it in this position

3. Keep pressing down on the protec-
tive bar – see arrow 1 – from on top
until you hear it click into place
4. Put the cover panel back in place
and press down firmly
5. Push the back panel of the head
restraint closed – see arrow 2.
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 sys-
tem.
Work done on the system that is carried
out improperly could lead to failure in
an emergency or accidental activation.
Regarding having the system checked
to ensure long-term operation: be scru-
pulous in adhering to the Service inter-
val display for maintenance intervals.
Every 2 years at the latest, the rollover
protection system must be inspected at
a BMW center.<

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
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 then 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 door locks.
Color-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYour BMW center can provide you with
details on the capabilities of the Vehicle
Memory and Key Memory systems.
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your vehi-
cle, refer to pages 31, 33
>Activates/deactivates the "Follow me
home" function, refer to page 96
>Activates/deactivates daytime driv-
ing lamps, refer to page 96
>Sets the units of measure for display-
ing time, outside temperature, dis-
tance traveled and fuel consumption
in the instrument cluster>Indicates via an acoustic tone that
PDC has been activated, refer to
page 87
>Switches on rear window defroster
automatically, refer to
pages 102, 107
>After giving an ice warning, the dis-
play returns to the previous setting,
refer to page 85.
Examples for Key Memory:
>Unlocks driver's door first, then the
vehicle's remaining locks, refer to
page 33
>Locks the vehicle automatically after
you start off, refer to page 34
>Automatically adjusts the driver's
seat to the personal programmed
settings when the vehicle is
unlocked, refer to page 57
>Automatic tilting of the passenger-
side mirror, refer to page 58.
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.<

mission, that the selector lever is in P
>Depress the clutch pedal at low tem-
peratures.
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable materi-
als – grass, hay, leaves, etc. Such con-
tact could lead to a fire, resulting in
serious personal injury and property
damage.<
