The passenger-side mirror fea-
tures a convex lens. When esti-
mating the distance between yourself
and other traffic, bear in mind that the
objects reflected in the mirror are closer
than they appear. This means that esti-
mations of the distance to following
traffic should not be regarded as pre-
cise.<

Interior rearview mirror with
automatic dimming featureThis mirror automatically responds to
ambient light and headlamp glare from
following vehicles by dimming through
an infinitely variable range and auto-
matically reverts to its clear, undimmed
setting whenever you shift into Reverse
or move the selector lever into
position R.
There are two photocells for automatic
dimming. One photocell – see arrow – is
positioned in the mirror's frame, while
the other is slightly offset on the oppo-
site 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.

55 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 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 provide
protection in the event of a collision
from the side. They help support the
respective seat occupant's upper body.
For information on the correct sitting
position, refer to page 46.
The side airbags in the rear pas-
senger area* of your vehicle may
already have been deactivated by a
BMW center. You may have them acti-
vated if you desire to do so. Please
contact your BMW center for additional
information.<
The airbags will not be triggered in
the event of a minor accident, cer-
tain vehicle rollover situations or colli-
sions 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 air-
bag restraint system from the vehicle. In
the event of a malfunction, deactivation
or triggered activation – as a response
to an accident – of the airbag restraint
system, consult your BMW center for
inspection, repair or disassembly. Mod-
ifications may not be made on either
the wiring or the individual components
in the airbag system. These include the
upholstered covers on the steering
wheel, instrument panel, side trim pan-
els of the doors and front roof pillars
and on the sides of the headliner. Do
not attempt to remove or dismantle 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
directly after the system has been trig-
gered, as otherwise there is a danger of
burns.<

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 may place his or her head on
or near the side airbag, if so equipped.
For example, a child – even though
belted – may fall asleep with his or her
head against the side airbag. It may be
difficult for a driver to ensure that chil-
dren in the rear seat will remain prop-
erly 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 by a BMW cen-
ter. 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.
In sensitive individuals, the ignition and
inflation noise may induce a mild hear-
ing loss that is temporary in most
cases.
Airbag warning information is also pro-
vided on the sun visors.This is the right way a child should sit in
a child restraint when rear side airbags
are provided.

57
This is the right way a larger child
should sit wearing the seat belt when
rear side airbags are provided.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 the ignition key is turned 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 triggered within their normal
response range, even if the level of
impact would normally have triggered
them. Have your BMW center inspect
the airbag system immediately.<

Transporting children safely
Leave the rear safety belts in the
holders if they are not needed to
avoid unwanted movement from the
safety belts at high speeds.<
Commercially available child seats
complying with the legal standard are
designed to be secured with a seat belt
or with the seat belt portion of a combi-
nation lap/shoulder belt. Improperly or
inadequately installed restraint sys-
tems 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, two additional tether
anchorage points have been provided.
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 39
2. Lift the headrest and pass the tether
strap between the headrest and the
seat back. It is recommended that
you return the head restraint back 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.

59
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 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, as 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 the
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 when-
ever 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
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.
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.
