Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
Protective action
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page43.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e. g. less severe acci-
dents, certain roll-over conditions, or rear-end
collisions.
Stickers on the rear door frame indicate
the status of the rear side airbags. If the
status cannot be clearly recognized, or if you
want to have the airbags activated/deactivated,
please contact your BMW center.<
For details on the correct seat position, refer to
page43.
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 retention system from the
vehicle. Do not modify or tamper with either the wiring or the individual components in the air-
bag system. This category includes the uphol-
stery in the center of the steering wheel, on the
instrument panel, the doors and the roof pillars
along with the sides of the headliner. Do not
attempt to remove or dismantle the steering
wheel. Do not touch the individual components
immediately after the system has been trig-
gered, because there is a danger of burns. In the
event of malfunctions, deactivation, or trigger-
ing of the airbag restraint system, have the test-
ing, repair, removal, and disposal of airbag gen-
erators executed only by a BMW center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Warnings and information on the airbags is also
provided on the sun visors.
Automatic deactivation of front
passenger airbags
The occupation of the seat is detected by eval-
uating the impression on the occupied seat sur-
face of the front passenger seat. The front and
side airbag on the front passenger side are acti-
vated or deactivated accordingly by the system.
The current status of the front passenger
airbag, i.e. deactivated or activated, is
indicated by the indicator lamp over the interior
rearview mirror, refer to Operating state of front
passenger airbags in the following.<

2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150-lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs.:
1,400 Ibs. minus 750 Ibs. = 650 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permissible load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
seat back.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
>Do not pile objects higher than the top edge
of the backrest.
>Sports Wagon:
Pull out the partition net, refer to page111,
and ensure that carried items cannot pass
through the partition net.
Wrap sharp-edged of pointed objects which
could strike the rear window while driving.

Things to remember when driving
120
Securing cargo
>Use the luggage net*, luggage straps, or
securing straps to hold down small and
lightweight luggage and cargo.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. Four lashing eyes
mounted in the luggage compartment or
cargo area are used to secure these heavy-
duty cargo straps, refer to illustration.
>Please observe the special instructions
supplied with the heavy-duty cargo straps.
Always position and secure the load as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
Use only the lashing eyes to secure heavy-duty
cargo straps, refer to illustration, otherwise the
cargo straps could become detached or the
vehicle could be damaged.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page221, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuvers.<
Roof-mounted luggage rack*
A special rack system is available as an option
for your BMW. Please comply with the precau-
tions included with the installation instructions.
Mounting points
The mounting points are located in the door
openings or on the roof rails
*.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its handling and steering response.
You should therefore always remember not to
exceed the approved roof load capacity, the
approved gross vehicle weight or the axle loads
when loading the rack.
You can find the specified weights under
Weights on page221 ff.
The load on the roof must be evenly distributed
and must not extend outward beyond the limits
of the loading surface. Always stow the heaviest
pieces at the bottom. Be sure that adequate
clearance is maintained for raising the glass
sunroof, and that objects do not project into the
opening path of the luggage compartment lid/
tailgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
