Vehicle Battery; Charging Battery - BMW 2006 M6 Owner's Manual

Mounting a wheel
1. Unscrew the lug bolts and remove the
wheel.
2. Remove accumulations of mud or dirt from
the mounting surfaces of the wheel and
hub. Also clean the lug bolts.
3. Position the new wheel or spare wheel.
Secure the wheel by screwing at least two
lug bolts into opposite bolt holes.
When you mount wheels other than Genu-
ine BMW light-alloy wheels, different lug
bolts may also be required.
4. Screw in the remaining lug bolts. Tighten all
the bolts securely in a diagonal pattern.
5. Lower the vehicle and remove the jack from
beneath the vehicle.
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. 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 and 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
page 74, and the Sequential Manual Trans-
mission, refer to After changing wheels/
tires on page 174.
4. Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Stowing wheel and tools
1. Lay the wheel in the tool mounting.
2. Lay the cover on the mounting.
3. Center the wheel and cover relative to the
lashing eyes 5.

4. Hook the belt into the lashing eyes.
5. Completely open the tensioning lock.
6. Thread the belt 3 through the axis 6 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.<
