Enlarging the cargo bay
When the hardtop is closed you can enlarge the
cargo bay:
To do so, press the cargo bay partition 1
upward.
Before opening the hardtop, pull the cargo bay
partition 1 down until it engages in both
guides 2.
Before moving the hardtop, ensure that
there are no objects on or next to the
cargo bay partition, othe rwise parts of the hard-
top may be damaged. Do not exceed the maxi-
mum loading height; refer to the sticker in the
cargo bay showing a line indicating the maxi-
mum height. Do not use fo rce to push down the
cargo bay partition. <
The retractable hard top can only be
opened if the cargo bay partition is in its
lowermost position and engaged on both
sides. <
Through-loading opening
with integrated
transport bag*
Always secure transported skis or similar
objects with the ski support
*; otherwise,
they could endanger occupants during braking
maneuvers and swerving. <
The transport bag lets you transport up to two
pairs of standard skis safely and cleanly.
The transport bag can hold skis up to a length of
5.4 ft/1.70 m. When transporting skis that are
5.4 ft/1.70 m in length, th e overall capacity of
the ski bag is reduced as the bag narrows.
Loading
1. Fold the cover down.
2. In the cargo bay: press the tab up and fold
the cover down.
3. Undo the fastener and spread out the trans-
port bag between the seats.
4. Insert the latch plate of the retaining strap
into the belt buckle under the transport bag.
5. Load the transport bag. The zipper eases
access to the stored items.
Only place clean skis in the transport bag. Wrap
sharp edges to prevent damage.

Practical interior accessories

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.
Ski support*
Always secure transported skis or similar
objects with the ski support* as they
could otherwise endanger occupants during
braking maneuvers and swerving. <
1. Remove both covers 1 with the screwdriver.
2. Attach the ski support 2 and fold it down,
see arrow.
3. Pull the fastener up and attach the rear of
the ski. Before closing the cargo bay, ensure that
the luggage compartment lid cannot be
damaged by the skis. <
Removing the transport bag
The transport bag can be completely removed,
e.g. for faster drying or to allow you to use other
inserts.
In the cargo bay: Press the handle up and fold
the transport bag completely down.
For more information on the various
inserts available, contact your BMW
center. <

Things to remember when driving
114
Load
The permissible load is the sum of the occu-
pants' weights and the weight of the cargo. The
greater the weight of the occupants, the less
cargo/luggage can be transported.
Stowing cargo
>Load heavy cargo as far forward as possi-
ble, directly behind the cargo bay partition,
and as low as possible.
> Cover sharp edges and corners.
Cargo, securing
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. Four lashing eyes are provided behind
the seats for attaching the cargo straps.
Adhere to the informat ion 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 a pproved axle loads, refer
to page 222, as excessive loads can pose a safety hazard, and may al
so 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. <
Before opening the hardtop, fold down
the cargo bay partition. Make sure the
cargo bay is loaded correctly, otherwise parts of
the hardtop can be damaged, refer to
page 105.<
