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.<

Xenon lamps*
These bulbs have a very long service life and are
highly unlikely to fail. If a xenon lamp fails never-
theless, switch on the fog lamps and continue
the journey with great care, provided that local
legislation does not prohibit this.
Have any work on the xenon lamp system,
including bulb replacements, performed
o n ly b y a BM W c e n t e r o r a w o r k s h o p t h a t w o r k s
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
Removing the headlamp cover
1.Pull the wire brackets over the notches, see
arrows, and fold to the side.
2.Fold away the headlamp cover.
Be careful when attaching the headlamp
cover and ensure that both wire brackets
are securely in place; otherwise, leaks could
occur and cause damage to the headlamp sys-
tem.<
Attach the headlamp cover in reverse order.

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 page220.
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
page74.
>Radio
In some cases, stations may have to be
stored again, refer to page143.
>Navigation system
Wait for the system to start, refer to
page137.
>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
page48.
>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 page87.
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.<
In the glove compartment
Accessing the fuse box:
1.Open the glove compartment.
2.Remove the damper, arrow1, from the
lower holder by applying forward pressure.
3.Disengage the glove compartment by
pressing on both tabs, arrows 2, and fold it
down.
Plastic tweezers are located on the distributor
box.
Information on fuse assignment can be found
next to the distributor box.
Spare fuses are available from your BMW cen-
ter.
After replacing a fuse, press the glove compart-
ment upward until it engages and reattach the
damper.
