Drive with your safety belt onFasten your safety belt at the beginning
of every trip.
To fasten:
Make sure you hear the lock engage in
the belt buckle.
To release:
Press the red button in the buckle. Hold
the belt and guide it back into its reel.
For care instructions, refer to "Caring
for your vehicle," page 119.520de020
For your safety, please comply
with the following instructions for
wearing safety belts. Otherwise, your
personal safety will be diminished, and
the safety belts' protective function
impaired. The following information also
applies to your passengers:
Never allow more than one person to
wear a single safety belt. Infants or
small children should never be held on
the lap of a passenger.
Avoid twisting the belt while routing it
firmly across the pelvis and shoulder,
wear it as snugly against your body as
possible. Do not allow the belt to rest
against hard or fragile objects in your
pockets. Never route the belt across
your neck, do not run it across sharp
edges and ensure that the belt does not
become caught or jammed.
Avoid wearing bulky clothing and pull
on the belt periodically to retension it
over your shoulder. In the event of a
frontal impact, a loose lap belt could
slide over your hips, leading to abdom-
inal injury. In addition, the safety belt's
restraint effectiveness is reduced if the
belt is worn loosely.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips,
where it will not exert pressure against
the abdominal area.<
If the safety belt system has been
subjected to the stresses involved
in an accident or damaged in any other
way, have the complete mechanism
replaced by your BMW center,
including the safety belt tensioner and
the belt anchorages checked. If a child
restraint system
* is in the vehicle
during an accident, consult the manu-
facturer's instructions regarding
replacement.<
Child restraint systems
*
Your car is equipped with an
airbag designed to provide supple-
mental restraint for the front passenger
in an accident. Because the backrest on
any rear-facing restraint device (of the
kind designed for smaller infants) would
be within the airbag's deployment
range, you should never mount such a
device in this car, as the impact of the
airbag against the child restraint's back-
rest could lead to serious injuries. Never
modify a child restraint system in any
way, as the result could be reduced
protection for your child.<

Airbags 1 Front airbag on driver and passenger
side
2 Side airbags on driver and passenger
sideProtectionThe front airbags protect the driver and
passenger in the event of severe frontal
impacts in which a safety belt alone is
not enough to afford optimal protection.
The side airbags help provide protec-
tion in the event of a collision from the
side. Each of the side airbags is
designed to help support the seat occu-
pant's upper body.520de021
The illustration shows the system's
effective response range.
The airbags do not respond to mi-
nor impacts, if the vehicle rolls
over, or if the vehicle is hit from the
rear.<520de022
Indicator lamp
The indicator lamp in the instru-
ment cluster comes on to
confirm the system's operational
status from ignition key position 1.
System operational:
>The indicator lamp comes on briefly
then goes out.
System malfunction:
>The indicator lamp fails to come on
>The indicator lamp comes on briefly
before going out and then lighting up
again.
A system malfunction could prevent the
system from responding to a high-
intensity impact sustained within its
normal response range.
Have your BMW center inspect the
system immediately.

AirbagsSitting correctly with airbags
Comply with the following instruc-
tions for the airbags, otherwise,
the airbags may not be able to provide
their maximum protection, with
resulting risks to personal safety. All
passengers in the vehicle should be
aware of and comply with this informa-
tion:
The airbag is a supplemental restraint
device; it is not a substitute or replace-
ment for your safety belt, which you
should continue to wear at all times.
When adjusting your seat, assume a
comfortable driving posture allowing
comfortable and secure access to all of
the vehicle's controls. Avoid sitting too
close to the steering wheel.
Always hold the steering wheel by the
rim Ð hands in the "9 o'clock" and
"3 o'clock" positions Ð otherwise, your
hands or arms could be injured if the
airbag is triggered.
Never allow any other passengers,
animals or objects to intrude into the
area between the airbag and the driver
or front passenger.
Do not use the cover panel above the
front passenger airbag as a storage
area.
Do not apply adhesive materials to the
cover panels of the airbags, or cover or
modify them in any other way.
Do not use a rear-facing child seat in the
front passenger seat. If you use a child
restraint system, carefully read and
comply with the instructions on page 53.
Be sure that child seats are installed
correctly and with the greatest possible
distance between them and the side
airbag. Do not allow children to lean out
of the child's seat in the direction of the
side trim panels. If they do so, serious
injuries can occur if the airbag is trig-
gered.<
Even when all these guidelines are
observed, there is still a small residual
risk of injury to the face, hands and
arms occurring from airbag deployment
in isolated instances.
The ignition and inflation noise may
cause a mild temporary hearing loss in
extremely sensitive individuals.
You will find the proper airbag safety
precautions on both sun visors and on
the instrument cluster (US models).
For additional information concerning
the airbag system, refer to pages 121
and 148.The illustration shows the correct
seating position for a child in a child
restraint system

Before installing any child-
restraint device or child seat,
please read the following:
Never install a rear-facing child restraint
system in the passenger seat of this
car.
If the airbag deploys and hits the back-
rest of the rear-facing child seat, it is
likely that the child sitting in the rear-
facing child seat will be seriously
injured or killed.
If it is necessary for a child (not an
infant) to ride in the car, certain precau-
tions should be taken. First, move the
passenger seat as far away from the
dashboard as possible. This important
precaution is intended to maximize the
distance between the airbag and the
child. Older children should be tightly
secured with the safety belt. Younger
children should be secured in an appro-
priate forward-facing child-restraint
system that has first been secured with
a safety belt.
In the interest of the child's safety,
please carefully read and comply with
the instructions for installation and
use provided by the child-restraint's
manufacturer whenever you use such a
device.
Do not allow children to lean out of a
child restraint system toward the door
or dashboard, as otherwise serious
injuries may result if the airbag deploys.
Always ensure that all occupants (of all
ages) remain properly and securely
restrained at all times.
Read carefully and comply with the
safety precautions covering safety belts
on pages 50. If you do not, the protec-
tive function of the safety belts will be
limited.<

Transporting children safelyChild seat securityThe safety belt on the passenger side
can be locked for mounting and
securing child-restraint systems.
A label with operating instructions is
attached to the belt next to the sliding
latch plate.520us003
To lock the beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.
The belt cannot be retracted further.
Comply with the installation instructions
provided by the manufacturer of the
child restraint system.To release the beltRelease the buckle, remove the child-
restraint system and allow the inertia
reel to retract the belt completely.

Information for your safetyThe factory has approved steel-belted
radials with emergency driving charac-
teristics for your vehicle. These tires
combine optimal driving safety with the
comfort you desire.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures
regularly (refer to page 26), at
least every two weeks and before
beginning a longer trip. If this is not
done, incorrect tire pressures can
cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Run-flat tiresYour BMW Z8 is equipped with run-flat
tires.
The assembly consists of self-support-
ing tires mounted on specially-designed
wheel rims. Special reinforcement
elements support the sidewalls in the
event of pressure loss. Although tire
performance is then restricted, the
vehicle can still be driven on the
deflated tire for a limited distance. Your
vehicle is equipped with a tire pressure
monitor that signals you in case of a flat
tire.
For further information, refer to
pages 67, 135.
Tire tread Ð tire damageInspect your tires frequently for tread
depth, wear, signs of damage and for
foreign objects lodged in the tread.
Tread depth should not be allowed to
fall below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base will indicate that the legally
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.390de331

Special features of winter tires Snow chains
*
Choosing the right tireFor winter road driving, BMW recom-
mends winter tires (M+S radial belt
tires). Although all-season M+S tires
provide better winter traction than stan-
dard summer tires with H, V, W and ZR
speed ratings, they generally fail to
provide the same levels of performance
as standard snow tires in winter driving.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Use only winter tires with emer-
gency driving characteristics as
there is no spare tire available if you get
a flat tire.
For further information, refer to
page 135.<
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which winter tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureOnce the tread depth on winter tires is
less than 0.16 in (4 mm), they are no
longer suitable for winter road driving,
and in the interest of safety should be
replaced.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
The use of narrow-link BMW snow
chains is permissible in pairs only on
the rear wheels with winter tires with
tire size 245/45 R 18 96 H. Comply with
all manufacturer's safety precautions
when mounting the chains.
Do not activate the RDW system
while using snow chains.
Malfunction warnings and undetected
losses in pressure are possible when
driving with snow chains.
For further information, refer to
page 67.<
