Under the hood
222
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.<

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-
mate. Your BMW center will be glad to advise in
all matters concerning the battery.
Battery replacing
Only use vehicle batteries that have been
approved for your vehicle by the manu-
facturer; otherwise, the vehicle could be dam-
aged and systems or functions may not be fully
available.<
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort functions are fully
available.
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 page239.
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
page83.
>Radio
In some cases, stations may have to be
stored again, refer to page157.
>Navigation system
Operability must be waited for, refer to
page134.>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
page114.
>Active steering
The system automatically initializes itself
briefly during a trip. The system is deacti-
vated during this time, refer to page96.
>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 center.
