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 area: 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.

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
Coupe
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.

Things to remember when driving
100
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. To attach the cargo
straps, there are two lashing eyes, arrows 1,
on the inside wall of the cargo area.
Depending on your vehicle's equipment,
there may be two additional lashing eyes,
arrows2, on the cargo area 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
f o r y o u r B M W . C o m p l y w i t h t h e d i r e c t i o n s g i v e n
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
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.
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.
Rear luggage rack*
A rear luggage rack is available as a special
accessory for your BMW. Comply with the
directions given in the installation instructions.

Under the hood

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
work according to BMW repair procedures with
correspondingly trained personnel. If this work
is not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
Hood
Releasing
Pull the lever.
Opening
To avoid damage, make sure that the
wiper arms are against the windshield
before you open the engine compartment. Do
not open the engine hood before the engine has
cooled down; otherwise, injuries may result.<
Press the release handle and open the hood.
Closing
Close the hood from a height of approx. 16 in/
40 cm with momentum. It must be clearly heard
to engage.
Make sure that the closing path of the
hood is clear; otherwise, injuries may
result.
If you see any signs while driving your vehicle
that the hood is not completely closed, stop at
once and close it securely.<

Replacing components
128 When mounting new tires or changing over
from summer to winter tires and vice versa,
mount run-flat tires for your own safety. In the
event of a flat, no spare wheel is available. Your
BMW center will be glad to advise you. Refer
also to New wheels and tires, page112.
The tools for changing wheels are avail-
able as optional accessories from your
BMW center.<
Jack mounting points
The jacking points are at the positions shown in
the illustration.
Vehicle battery
Battery care
The battery is 100 % maintenance-free, the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
ma te. Your BM W center will be glad to advise in
all matters concerning the battery.
Charging the battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine off. Connections, refer to Jump-starting
on page131.
Disposal
Have old batteries disposed of by your
BMW center or bring them to a recycling
center. Maintain the battery in an upright posi-
tion for transport and storage. Always secure
the battery against tipping over during trans-
port.<
Power failure
After a temporary power loss, the functioning of
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
page62.
>Radio
Stations must be stored again, refer to the
separate Owner's Manual for Radio.
>Glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Seat and mirror memory
*
The positions must be stored again, refer to
page40.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page87.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page70.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating; oth-
erwise, this could lead to a circuit overload, ulti-
mately resulting in a fire in the vehicle.<
