Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., 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.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page213.
Disposal
Have old batteries disposed of by your
BMW center or bring them a recycling
center. Maintain the battery in an upright posi-
tion for transport and storage. Always restrain
the battery to prevent it from tipping over during
transport.<
Power failure
Following a temporary power failure, e.g. due to
a discharged battery, the use of some equip-
ment will be restricted, requiring its reinitializa-
tion. In the same way, individual settings are lost
and must be updated again:
>Seat, mirror and steering wheel
* memory
The positions must be stored again, refer to
page45.
>Time and date
Must be updated again, refer to page69.
>Radio
Radio stations need to be stored again,
refer to page140.
>Navigation system
You must wait until the system becomes
functional again, refer to page116.>Power windows
The pinch prevention system for the power
windows must be reinitialized, refer to
page36.
Talk to your BMW center before placing
the stored vehicle back in service. <
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.<

Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW with
power from the battery in a second vehicle. You
can also use the same method to help start
another vehicle. Use only jumper cables with
fully-insulated clamp handles.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible personal injuries.<
Preparation
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
This information can be found on the bat-
tery.
2.Switch off the engine of the assisting vehi-
cle.
3.Switch off any electrical systems and com-
ponents in both vehicles.

Giving and receiving assistance
214 There must not be any contact between
the bodies of the two vehicles, otherwise
there is a danger of shorting.<
Connecting jumper cables
To avoid personal injury from sparks, fol-
low this sequence when connecting
jumper cables.<
In your BMW M6, the so-called jump-starting
terminal for jump starting in the engine com-
partment serves as a positive terminal for the
battery, also refer to engine compartment over-
view on page193. The cover cap is marked with
a+.
1.Fold open the cover of the BMW jump-
starting terminal. To do so, pull the tab.
2.Attach one end of the jumper cable plus/+
to the positive terminal of the battery or a
jump-starting terminal of the vehicle provid-
ing assistance.
3.Attach the second end of the cable to the
positive terminal of the battery or to a start-
ing-aid terminal of the vehicle to be started.
4.Attach one end of the jumper cable minus/–
to the negative terminal of the battery or to
an engine or body ground of the assisting
vehicle.Your BMW M6 has a special nut as body
ground or negative terminal.
5.Attach the second end of the cable to the
negative terminal of the battery or to the
engine or body ground of the vehicle to be
started.
Starting engine
1.Start the engine on the assisting vehicle
and allow it to run at idle for several minutes
at slightly increased speed.
2.Start the engine on the other vehicle in the
usual way.
If the first starting attempt is not successful,
wait a few minutes before another attempt
in order to allow the discharged battery to
recharge.
3.Let the engines run for a few minutes.
4.Disconnect the jumper cables by reversing
the connection sequence.
Check the battery and recharge if necessary.
Never use spray fluids to start the
engine.<
Tow-starting and towing
Observe applicable laws and regulations
for tow-starting and towing.<
Do not transport any passengers other
than the driver in a vehicle that is being
towed.<
Using tow fitting
The threaded tow fitting is stored in the tool kit
mounted on the inside of the luggage compart-
ment under the floor mat, refer to page203, and

should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
Only use the tow fitting that comes with
the vehicle and screw it in as far as possi-
ble. Use the tow fitting for towing only on roads.
Avoid lateral loading of the tow fitting, e.g. do
not lift the vehicle by the tow fitting. Otherwise
damage to the tow fitting and the vehicle can
occur.<
Access to screw thread
Front: press the arrow symbol on the cover in
the bumper.
Rear: press the arrow symbol on the cover while
prying out the cover upward by hand.
Being towed
Make sure that the ignition is switched on,
refer to page55, otherwise the low
beams, tail lamps, turn signals and windshield
wipers would not be available. Do not tow the
vehicle with the rear axle raised, as otherwise
the steering can turn to the left or right.When
the engine is stopped, there is no power assist.
This then requires increased effort for braking
and steering.<
Switch on the hazard warning flashers depend-
ing on the local regulations. If the electrical sys-tem fails, mark the vehicle to be towed, e.g. with
a sign or warning triangle in the rear window.
Manual transmission
Gearshift lever in neutral position.
Sequential Manual Transmission with
Drivelogic
Make sure that selector lever position N is
engaged with the ignition switched on, as
otherwise the engine can be damaged during
towing.<
Towing methods
Do not lift vehicle by tow fitting or body
and chassis parts; otherwise, damage
may result.<
In some countries, towing with tow bars or
ropes in public traffic is not permitted. Familiar-
ize yourself with the regulations on towing in the
respective country.
With tow bar
The towing vehicle may not be lighter
than the vehicle to be towed, otherwise it
will not be possible to reliably control vehicle
response.<
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 observe the following:
>Clearance and maneuvering capability will
be sharply limited during cornering.
>When mounted at an angle, the tow bar will
exert lateral forces, tending to push the
vehicle sideways.
Only attach the tow bar to the tow fittings,
as attachment to other vehicle parts can
lead to damage.<
With tow rope
When starting off in the towing vehicle, make
sure that the tow rope is taut.
To avoid jerking and the associated
stresses on vehicle components when
towing, always use nylon ropes or nylon straps.

Giving and receiving assistance
216 Only attach tow ropes to the tow fittings, as
attachment to other vehicle parts can lead to
damage.<
With tow truck
Do not tow the vehicle with only the front
or rear axle raised, as otherwise the
engine may be damaged or the steering can
turn to the left or right.<
Have the vehicle transported on a flatbed sur-
face only.
Tow-starting
Do not tow-start the vehicle if possible, but
instead start the engine by means of jump start-
ing, refer to page213. Vehicles equipped with a
catalytic converter should only be tow-started
when the engine is cold.
