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
218
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
In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the hood. 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
Let the hood drop from a height of approx. 10 in/
25 cm. 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
236
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
page75.
>Radio
In some cases, stations may have to be
stored again, refer to page147.
>Navigation system
Operability must be waited for, refer to
page124.
>Glass roof
It may happen that the roof can only be
raised. The system must be initialized.
Please contact your BMW center.
>Panorama 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
page45.
>Inside rearview mirror with digital compass
The system must be calibrated, refer to
page104.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page88.
>xDrive
The system automatically initializes itself
during a trip. Indicator lamps light up during
this time. If the lamps do not go out during
the current trip, have the system checked.
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.<
Open the cover in the glove compartment and
remove it.
Plastic tweezers are located on the distributor
box.
See the rear of the cover for information on fuse
assignment.
Spare fuses are available from your BMW cen-
ter.
