2008 BMW M6 CONVERTIBLE battery

Replacing components
222
After mounting
1.Tighten the lug bolts in a diagonal pattern.
To ensure safety, always have the
lug bolts checked with a calibrated
torque wrench as soon as possible to
ensure that they are tightened to the speci-
fied torque. Otherwise, incorrectly tight-
ened lug bolts are a hidden safety risk. The
tightening torque is 88.5 lb ft/120 Nm.<
2.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve stem
seal caps against dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
3.Initialize the Flat Tire Monitor, refer to
page86, and the Sequential Manual Trans-
mission, refer to After changing wheels/
tires on page207.
4.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Stowing wheel and tools
Convertible: a rear wheel can only be
transported with the convertible top com-
partment floor folded up.<
1.Lay the wheel in the tool mounting.
2.Lay the cover on the mounting.
3.Coupe: center the wheel and cover relative
to the lashing eyes5.
Convertible: slide the wheel as far as possi-
ble to the left and to the rear.
4.Coupe: hook the belt into the lashing eyes5
and lay it in the belt guide which runs in the
center of the lid.Convertible: hook the belt into the lashing
eyes5 and7 and lay it in the belt guide of
the lid which runs offset.
5.Completely open the tensioning lock.
6.Thread the belt3 through the axis6 of the
tensioning lock without twisting it and ten-
sion it by hand.
7.Tighten the belt firmly with the tensioning
lock by opening and closing the lock several
times.
8.Fold the tensioning lock closed and stow
the protruding belt end.
Driving with spare wheel
With certain wheel-and-tire combinations
the size of the spare wheel differs from
that of the other wheels. The spare wheel is
equivalent to them in all load and speed ranges.
However, to restore the original state, the nor-
mal wheel should be remounted as soon as
possible.<
Vehicle battery
Maintenance
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.

posed of by your BMW center or deposit
them at a recycling center. Maintain the battery
in an upright position for transport and storage.

stitute of another color or amperage rating, as
this could lead to overloading of the wiring, ulti-
mately resulting in a fire in the vehicle.<

located in the compartment for the onboard tool
kit, refer to page216.
Information on fuse allocation is located below
the bracket for the onboard tool kit, see below.

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.<
Preparing
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 vehicle provid-
ing assistance.
3.Switch off any electrical systems and com-
ponents in both vehicles.

Giving and receiving assistance
226 There must not be any contact between
the bodies of the two vehicles; otherwise,
there is a danger of short circuiting.<
Connecting jumper cables
To avoid personal injury from sparks,
follow 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 page209. 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 jump-
starting 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 vehicle
providing assistance.
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 page216, and
should always remain in the vehicle. It can be
screwed in at the front or rear of the BMW.
