Cargo area
Roller cover
Pull out the cover and hook it into the retaining
fixtures.
Do not place objects on the cover; other-
wise, they could endanger the car's occu-
pants, e.g. in the case of braking or sudden
swerving.
Do not let the cover retract; otherwise, it could
be damaged.<
Raising the roller cover
Press the button: the roller cover is raised.
Before closing the rear window or tailgate,
press the roller cover downward until it
engages.
Expanding the cargo area
The rear seat backrest is divided. You can fold
down either division in order to expand the
cargo area.
Reach into the recess and pull forwards.
When folding the backrest back up, make
sure that the catch engages properly. If
you cannot see a red warning area in the recess,
the catch is properly engaged. Otherwise,
cargo can be thrown around inside the passen-
ger compartment and endanger the car's occu-
pants, e.g. in the case of braking or sudden
swerving.<
Observe the instructions concerning the
safety belt on page41 to ensure the best
possible personal protection.<

Partition net
Do not let the partition net retract; other-
wise, there is a risk of danger and the par-
tition net could be damaged.<
Use the loop strap to pull the partition net out of
the casing. Grip the bar on both ends and insert
it into the retaining fixtures, arrow 1. This can
best be done from the rear seat.
When you no longer require the partition net,
grip both ends of the bar and take it out of the
retaining fixtures, arrow 2. Let the partition net
slide into the casing slowly.
With cargo area expanded
1.Fold down both rear seat backrests, refer to
Expanding the cargo area.
2.Use the buttons to unlatch the casing on
both sides, arrow 1.3.Pull the casing out backwards, arrow 2,
without tilting it.
4.Slide the casing into the guides on the
backs of the seat backrests.
5.Carefully pull out the partition net and insert
it into the front retaining fixtures, refer to
Partition net above. This can best be done
from the front seat.
Follow the same steps in reverse order to return
the partition net and seats to their original posi-
tions. Finally, slide the casing into both retaining
fixtures on the sides until it engages. Tug on the
casing to check if it is properly locked in place.

Loading
1.Fold down the center armrest.
2.Press the button, reach into the recess and
fold down the cover.
3.Open the Velcro fastener, spread the ski
bag between the front seats and insert the
skis or snowboards.
The zip fastener makes objects in the ski
bag easier to reach.
4.Insert the latch plate of the ski bag's retain-
ing strap in the center belt buckle.
Only place clean skis in the ski bag. Wrap sharp
edges to prevent damage.
Securing cargo
After loading, secure the ski bag and its con-
tents. Tighten the retaining strap on the ten-
sioning buckle for this purpose.Secure the ski 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 ski bag, perform the steps
described for loading in reverse order.
Removing the ski bag
The ski bag can be completely removed, e.g. for
faster drying or to allow you to use other inserts.
1.Fold down the center panel in the rear seat
backrest.

When the vehicle is parked
Condensation forms while the automatic cli-
mate control is in operation, and then exits
under the vehicle. Traces of condensed water
under the vehicle are therefore normal.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. This can ultimately
result in a sudden blowout.<
Make sure that no liquids are spilled or
leak from their containers in the cargo
area, as this could result in damage to the vehi-
cle.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX kg or YYY lbs. Otherwise, overloading
can result in damage to the vehicle and
unstable driving conditions.<
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 kilograms or YYY
pounds.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the YYY 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 lbs. minus 750 lbs. = 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 the occupants, the less cargo/lug-
gage can be transported.
Stowing cargo
>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.

Things to remember when driving
120
Sedan
Sports Wagon
>Use the partition net to protect passengers,
refer to page111. Make sure that objects
cannot penetrate the partition net.
>Do not stack cargo higher than the upper
edge of the backrests.
>Place protective material around any
objects which could bump against the rear
window while the vehicle is in motion.
Securing cargo
>Secure smaller and lighter items using
retaining straps, a cargo area 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 for attaching the cargo straps.
Two are located on the cargo area
sidewalls1, two more are on the rear cargo
area panel2.
Please comply with the information sup-
plied 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 page247, 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
page51; otherwise, these could be damaged.<

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 page247.
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
that adequate clearance is maintained for rais-
ing the glass roof, and that objects do not
project into the opening path of the trunk lid/
tailgate.
Fasten 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.

Under the hood
Do not work on the car unless you pos-
sess the necessary technical knowledge.
If you are unfamiliar with the statutory guide-
lines, have any work on the vehicle performed
only by a BMW center or by a workshop that

some equipment may be limited and require
reinitialization. Individual settings may likewise
have been lost and will have to be programmed:
>Time and date
These values must be updated, refer to
page75.
>Radio
In some cases, stations may have to be
stored again, refer to page147.
