2008 BMW 750I SEDAN ECU

Replacing components
218
Battery switch
Before storing the vehicle for an extended
period of several weeks or more, slide the bat-
tery switch located behind the trim panel on the
right side of the luggage compartment to OFF.
This reduces the current flow from the battery
for the period during which the vehicle remains
parked. A message appears on the Info Display.
Please take note of the supplementary informa-
tion provided on the Control Display.
Disposal
Have old batteries disposed of following
replacement at your BMW center or bring
them to a collection point. Maintain the battery
in an upright position for transport and storage.
Always secure the battery to prevent it from tip-
ping over during transport.<
Power failure
After a temporary interruption in electrical
power, the functioning of some equipment may
be limited and must be reinitialized. Individual
settings are also lost and must be updated
again:
>Seat, mirror, and steering wheel memory
The positions must be stored again, refer to
page46.
>Time and date
These must be reset, refer to page84.
>Radio
Stations must be stored again, refer to
page158.
>Navigation system
You must wait until it becomes operational
again, refer to Inserting navigation CDs/
DVDs on page130.
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, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Spare fuses and plastic tweezers are stored in
the fuse box in the luggage compartment.
In glove compartment
Press the tab on the cover to the front, then fold
down the cover.
Additional information about fuse allocations is
provided on the fuse card in the compartment.
In the luggage compartment
Pull the handle to fold down the trim on the right
wall.
Additional information about fuse allocations is
provided on the side panel.

Giving and receiving assistance
222 The tow fittings used should be on the same
side on both vehicles. Should it prove impossi-
ble to avoid mounting the tow bar at an offset
angle, please be aware of the following:
>Clearance and maneuvering capability will
be strictly limited in corners.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only secure the tow bar to the tow fitting;
otherwise, damage can occur when it is
secured to other parts of the vehicle.<
With tow rope
When starting off in the towing vehicle, make
sure that the towrope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.
Only secure the tow rope on the tow fitting; oth-
erwise, damage can occur when it is secured on
other parts of the vehicle.<
With tow truck
Have the BMW transported with a tow truck
with a so-called lift bar or on a flat bed.
Do not lift vehicle by tow fitting or body
and chassis parts; otherwise, damage
may result.<
Tow starting
It is not possible to start the motor by tow start-
ing.
Starting assistance, refer to page220.
Have the cause of the starting difficulties reme-
died.
