2008 BMW M6 belt

Technology for comfort, convenience and safety
92 But the front, knee and side airbags on the
front passenger side are still deactivated.
Operational readiness of airbag system
From radio readiness, refer to page59, the
warning lamp lights up briefly, indicating the
operational readiness of the entire airbag sys-
tem and the safety belt tensioners.
Airbag system malfunction
>Warning lamp does not light up as of radio
readiness.
>Warning lamp lights up continuously.
Have the airbag system checked immedi-
ately in case of a malfunction; otherwise,
there is a danger that the airbag system may not
respond in the expected manner in an accident
despite an impact of corresponding intensity.<
Convertible: rollover
protection system
The rollover protection system is automatically
activated in the event of an accident or a critical
driving situation, extreme inclination on the lon-
gitudinal axis, or loss of ground contact. The
rollover bars located behind the rear head
restraints are deployed within fractions of a sec-
ond.
As a supplement to the rollover bar integrated
into the windshield frame, the rollover protec-
tion system ensures that all vehicle occupants
have the necessary headroom.
Always keep the path of movement of the
rollover protection system clear.
In less severe accidents, you are protected by
the fastened safety belt and, depending on the severity of the accident, the belt tensioner and
the multistage airbag restraint system.<
Lowering
If the rollover protection system experienced no
impact after automatic activation, then it can be
lowered again. No tools are necessary for this
purpose.
1.Press the release backward and hold in that
position.
2.Press the rollover protection unit halfway
down from above.
3.Let go of the release.
4.Press the rollover protection unit down until
it snaps into place.
5.Use the same procedure for the second roll-
over protection unit.
Have the rollover protection system checked
after unexpected triggering.
Never move the convertible top when the
rollover protection system is raised.
No changes of any nature may be made to the
individual components of the rollover protec-
tion system and wiring.
Work on the rollover protection system may
only be performed at a BMW center.

Securing cargo
After loading, secure the ski bag and its con-
tents. To do so, tighten the retaining belt at the
buckle.
Secure the ski bag in this way. If you fail to
do so, it could endanger vehicle occu-
pants during braking or evasive maneuvers.
To refit the filler element, insert the two tabs at
the bottom into the strip and press the filler ele-
ment back into place. Make sure that you do not
damage the rear seat upholstery.<

Wheels and tires

Tire identification marks
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed letter
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Z = over 150 mph/240 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the US Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 3307 indicates that the tire was manu-
factured in week 33 of 2007.BMW recommends replacing all tires at least
every 6 years, even if some tires may last for
10 years. This also concerns the tire of the
spare wheel
*.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half, 1γ, times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may
depart significantly from the norm due to varia-
tions in driving habits, service practices and dif-
ferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g.
Nominal width in mm
Aspect ratio in Ξ

Rim diameter in inches

Spare wheel*
1.Fold up the convertible top compartment
floor, refer to Convertible: increasing lug-
gage compartment capacity, page35.
2.Pull back lock1, fold open tensioning lock2
completely and loosen the belt3.
3.Remove the cover4.
4.Take the tool mounting out of the spare
wheel.
5.Remove the spare wheel.
Preparing wheel change
1.Observe the safety precautions above.
2.Prevent the vehicle from rolling:
Place the chock behind the front wheel on
the other side of the vehicle, or on inclines,
in front of this wheel. On steeply inclined
roads, always secure the vehicle against
rolling.
3.Loosen the lug bolts a half turn.
Jacking up vehicle
The jacking points for the car jack are located in
the positions shown.1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base rests on the ground
perpendicularly beneath the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
2.Guide the jack head into the rectangular
recess of the jacking point when cranking
up, refer to illustration detail.
3.Jack the vehicle up until the wheel you are
changing is raised from the ground.
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.

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.
