Convertible: through-loading
opening with integrated
transport bag
*
The transport bag is designed for safe, clean
transport of up to 4 pairs of standard skis or up
to 2 snowboards.
With the transport bag you can stow skis up to a
length of 6.6 ft /2.0 m. When skis of 6.6 ft/2.0 m
length are loaded, the overall capacity of the ski
bag is reduced due to its tapered design.
When using the transport bag, it is not
permissible to transport passengers in
the rear seats.<
Loading
1.Pull the grip in the filler piece of the rear
backrest up and take out the filler piece.
2.Place the filler piece onto the seat cushion
with the backrest side facing up.
3.In the cargo bay: press the two recesses
together and fold down the cover.
4.Release the strap, lay out the transport bag
between the front seats and load it.
The zip fastener makes objects in the ski
bag easier to reach.Ensure that the skis are clean when you load
them into the transport bag. Wrap sharp edges
to prevent damage.
Securing cargo
After loading, secure the transport bag and its
contents. Tighten the retaining strap on the
tensioning buckle for this purpose.
Secure the transport bag in the manner
described, otherwise it could endanger
the car's occupants, e.g. in case of heavy brak-
ing or sudden swerving.<
To store the transport bag, perform the steps
described for loading in reverse order.

Things to remember when driving
100
Convertible
>Position heavy objects as low and as far for-
ward as possible, ideally directly behind the
respective seat backrests.
>Cover sharp edges and corners.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Secure smaller and lighter items using
retaining straps
*, a cargo bay net* or draw
straps
*.
>Heavy-duty cargo straps
* for securing
larger and heavier objects are available at
your BMW center. To attach the cargo
straps, there are two lashing eyes, arrows 1,
on the inside wall of the cargo bay. Depend-
ing on your vehicle's equipment, there may
be two additional lashing eyes, arrows2, on
the cargo bay sidewalls.
Follow the information included with the
cargo straps.
Always position and secure the cargo as
described above, so that it cannot endan-
ger the car's occupants, for example if sudden
braking or swerving is necessary.
Never exceed either the approved gross vehicle weight or either of the approved axle loads, refer
to page149, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of traffic safety laws.
Heavy or hard objects should not be carried
loose inside the car, since they could be thrown
around, for example as a result of heavy braking,
sudden swerves, etc., and endanger the occu-
pants.
Only attach the cargo straps using the lashing
eyes shown in the illustration. Do not secure
cargo with the anchors for tether straps, refer to
page45, otherwise these could be damaged.<
Coupe: roof-mounted
luggage rack*
A special rack system is available as an option
for your BMW. Comply with the directions given
in the installation instructions.
Mounting points
Fold open the cover.
Loading roof-mounted luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
vehicle 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 applicable data under Weights
on page149.
The roof load must be distributed uniformly and
should not be too large in area. Heavy items
should always be placed at the bottom. Be sure

during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.

A rear-mounted luggage rack is available as a
special accessory for your BMW. Comply with
the directions given in the installation instruc-
tions.
Mounting points
The mounting points are located under the pro-
tective covers in the bumper.
Loading the rear-mounted luggage
