Safety belts Airbags Child restraint systems*
Do not install a rear-facing child
restraint system in the front
passenger seat of your vehicle. If you
do so, the child could be injured in an
accident when the airbag is triggered.
Children should always ride in the rear
and the restraint systems should be
secured with the safety belts.
Do not modify the child restraint system
in any way. If you do so, it will not
provide your child with maximum
protection.<
1 Front airbags for driver and
passenger
2 Side airbags for driver and passenger
(front and rear
*)
Protective effectThe front airbags protect the front-seat
occupants in the event of a severe
frontal collision on which the protection
afforded by the belts alone may no
longer be sufficient. 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
occupant's upper body.46cde048
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.<
The illustration depicts schematically
the primary directions of vehicle impact
that initiate airbag deployment.
The airbags will not be triggered in
the event of a minor accident, a
vehicle roll-over, or collisions from the
rear.<

Transporting children safelyCommercially 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 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
anchorage points (refer to the arrows in
the illustration) have been provided.
They are located under the convertible
top compartment.
Depending on the location selected for
seating in the rear passenger area,
attach the tether strap to the corres-
ponding anchorage point to secure the
child restraint system.46cus001
Lift the respective 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 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 rear-facing child restraint
system (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, 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 a 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 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 rear-facing child restraint
system in the front passenger seat.
We strongly urge you to carefully read
and observe the instructions for instal-
lation and use provided by the child
restraint's manufacturer whenever you
use such a device.
Allways 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
practice for securing child restraint
systems in motor vehicles.

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.46cus027
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 comply with the installation
instructions provided by the manufac-
turer 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.

Ski bag
*
The ski bag allows the safe and clean
transport of up to three pairs of skis or
up to two snowboards.
The length of the ski bag and the addi-
tional space provided in the luggage
compartment make it possible to carry
skis up to 6.8 ft long (2.1 0 meters).
Because of the tapered shape of the
bag, the ski bag can only accommodate
two pairs of skis up to 6.8 ft long
(2.1 0 meters).
Loading1 Take the safety belts out of their
brackets.
2 Press button downward (arrow) and
remove the filler piece by pulling it
forward.
3 Extend the ski bag between the front
seats. The zipper provides conve-
nient access to stored items and it
allows the ski bag to dry faster.46cde066
4 Press the release button in the
luggage compartment (arrow).
5 Use the magnetic holder to fasten the
cover panel to the back wall.
To store the ski bag, perform the above
steps in reverse sequence.
Secure the skis or other objects in
the bag by tightening the strap
with the buckle.<
Please be sure that your skis are clean
before loading them into the bag. Avoid
damage from sharp edges during
loading.46cde065

Stowing cargo If you are transporting a load in your
BMW:
>Load heavy cargo as far forward as
possible Ð directly behind the back-
rests or the luggage compartment
partition Ð and as low as possible.
>Cover sharp edges and corners.46cde063
With the convertible top closed,
you can increase the space in
your luggage compartment. Refer to
page 41.
We recommend that you always fold
the convertible top compartment panel
down as soon as you have removed
your cargo from the luggage compart-
ment. This way, you can be sure that
you can always operate the convertible
top at any time.
Conversely, when the convertible top is
closed, raise the convertible top
compartment panel before stowing
your cargo in the luggage compartment
to avoid any damage to the convertible
top compartment or your load.<

Cargo loadingSecuring the load >For small, light items, use the rubber-
lined non-skid side of the floor mat or
secure with a luggage net
* or flexible
straps (refer to page 41).
>For large, heavy pieces, see your
BMW center for load-securing
devices
*. Lashing eyes (arrow) are
provided at the inner corners of the
luggage compartment for attaching
these load-securing devices.
>Comply with the information enclosed
with the load-securing devices.
46cde008
Always position and secure the
load correctly. If you do not, it can
endanger the passengers during
braking or evasive maneuvers.
Do not exceed the approved gross
weight and axle load (refer to page 198),
otherwise the vehicle's operating safety
is no longer assured and you are in
violation of the law.
Do not stow heavy or hard objects in
the passenger compartment without
first securing them. Otherwise they
would be thrown around during braking
and evasive maneuvers and endanger
the occupants.<

Roof-mounted luggage rack for the hardtop
*
AnchorsAccess to the anchors:
To open the cover (arrow), please use
the tool included with the roof-rack
system.
A special roof-rack system is available
for your BMW as an optional extra.
Please comply with the precautions
included with the installation instruc-
tions.
Because roof racks raise the center of
gravity of the vehicle when loaded, they
exercise a major effect on its handling
and steering response. You should
therefore always remember not to
exceed the approved roof weight, the
approved gross vehicle weight or the 46cde097
axle loads when loading the rack. Perti-
nent specifications are listed under
"Technical Data," page 198.
Make sure that the load is not too
heavy, and distribute it evenly.
Always load the heaviest pieces first (on
the bottom). Be sure that objects do not
project into the opening path of the
luggage compartment lid.
Secure the roof luggage correctly and
securely to prevent it from shifting or
being lost during driving (danger to
following traffic).
Drive smoothly and avoid sudden
acceleration or braking. Do not corner
at high speeds.
The roof load increases aerodynamic
resistance, which in turn increases fuel
consumption and places additional
stress on the vehicle itself.

Antilock Brake System (ABS)The concept ABS enhances active safety by helping
to prevent the wheels from locking
under braking. This is because locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
The system can achieve the shortest
braking distances possible under most
conditions (on straight-aways and in
curves, on asphalt, ice, wet road
surfaces, etc.).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help maintain steering control and
maneuverability Ð on all types of road
surfaces (asphalt, concrete, mud, wet
road surfaces, snow, ice).
Braking with ABSAt about 6 mph (10 km/h), the system
becomes operative. Whenever the
vehicle's speed drops below approx.
4 mph (6 km/h), the ABS is deactivated.
This means that the wheels can lock in
the final phase of a panic stop Ð a factor
of no significance in actual use.
If you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can nevertheless
avoid possible obstacles with a
minimum of steering effort.
The ABS system closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you
should adapt road speed to the road
conditions.
On road surfaces that have a loose
surface layer on a firm base with good
traction (on gravel or snow, for
example), or when snow chains are
mounted, braking distances may be
longer than with locked wheels. Nevertheless, ABS possesses the
advantage of vehicle stability and
steering response.
Information for your safetyNot even ABS can suspend the laws of
physics. ABS cannot prevent the
consequences of brake applications
with inadequate clearances for safety
between vehicles, when exceeding the
speed limit, or the risks involved when
aquaplaning occurs. Responsibility for
these types of situations remains in the
hands (and at the feet) of the driver. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking
increased risks.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<

HoodTo closeAllow the hood to fall from a height
of about 12 in (30 cm) so that it audibly
engages.
To avoid injuries, be sure that the
travel path of the hood is clear
when it is closed, as with all closing
procedures. If it is determined that the
hood is not completely closed while
driving, stop immediately and close
it securely.<462de270
