Refueling
Always observe all safety notices
posted at the service station when
refueling. Never carry spare fuel con-
tainers in your vehicle. Whether empty
or full, these containers can leak, cause
an explosion, or lead to fire in the event
of a collision.<
Simple and environmentally
friendly
Open the fuel filler cap carefully to
prevent fuel from spraying out. Fuel
spray may cause injury. Do not attempt
to continue adding fuel to the last drop,
as this practice can cause fuel to spill.<
Keep the fuel filler cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling the
nozzle out of the pipe during refueling
>results in premature pump shutoff
>and will reduce the effect of the vapor
recovery system on the pump.
As long as the filler nozzle is used prop-
erly, the fuel tank is full whenever the
nozzle shuts off the first time.
394de120
Refill early to avoid damaging the
catalytic converter; never attempt
to drive to the last drop of fuel in the
tank.<
Tank capacity: approx. 18.5 gal.
(70 liters), with reserve of approx.
2.5 gal. (10 liters).
Close the fuel filler cap carefully
after refueling until a click is
heard. While closing, be sure not to
squeeze the strap which is fastened to
the cap. A loose or missing cap will
activate the message "CHECK FILLER
CAP" in the Check Control.<

Airbags1 Front airbags on the driver and
passenger sides
2 Head protection airbags on driver
and passenger side (front and rear
*)
3 Side airbags on driver and passenger
side (front and rear
*)
Protective effectThe front airbags help to protect the
driver and passenger in the event of a
head-on collision where the protection
provided by the safety belt alone would
not be adequate. The head protection
airbags and side airbags help provide
protection in the event of a collision
from the side. Each of the side airbags
is designed to help support the occu-
pant's upper body.39mde084
The side airbags in the rear pas-
senger area
* of your vehicle may
already have been deactivated, either
at the time of manufacture or by a BMW
center. You may have them activated if
you desire to do so. Please contact
your BMW center for additional infor-
mation.<
For information on the correct seating
position, refer to page 40.
The airbags will not be triggered in
the event of a minor accident, a
vehicle rollover or a collision from the
rear.<
Never apply stickers or adhesive-
backed objects of any kind to the
airbag covers. Never attempt to reup-
holster the covers or modify them in any
way. If the airbags deploy in response
to an accident, if you note any signs of
system malfunction, or if you wish to
have any parts of the airbag passenger-
restraint system deactivated, always
contact your BMW center, to whom we
strongly urge you to entrust all testing,
repair and dismantling operations.
Never attempt to modify or tamper with
either the system's electrical wiring or
any of its individual components.
System components include the uphol-
stered surfaces on the steering wheel,
instrument panel, the trim panels on the
front and rear doors and the roof braces
as well as the sides of the headliner
above the doors.
Never attempt to remove or dismantle
the steering wheel.
To ensure compliance with official
safety regulations, always entrust dis-
posal of airbag generators to your BMW
center. Attempts to carry out service
procedures undertaken by anyone
other than specially-trained profes-
sionals can result in system failure or
undesired airbag deployment, both of
which can lead to personal injury. If the
airbags deploy in response to an acci-
dent, always remember to avoid all
contact with system components, as
they are hot and can cause burns in the
period immediately following deploy-
ment.<
All vehicle occupants should
always sit upright and be properly
restrained (infants and small children in
appropriate child-restraint systems;
larger children and adults using the
safety belts). Never let an occupant's
head rest near or on a side airbag: the
inflating airbag could cause a serious or

To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following.
Your BMW M5 is a masterpiece of
superlative technology. To ensure
that you derive maximum satisfaction
from its extensive array of advanced
features while simultaneously creating
the basis for many years of driving plea-
sure, we urge you to observe the fol-
lowing precautions during the initial
period of operation.<
Engine and differentialUp to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
5,500 rpm or 105 mph (170 km/h)
during this period.
Comply with all official speed limits.
Do not depress the accelerator pedal to
the full-throttle position.
Following the Break-in inspection at
1,200 miles (2,000 km), you can gradu-
ally increase engine or road speeds.
You should also comply with these
break-in procedures if the engine or dif-
ferential is replaced later in the course
of the vehicle service life.
TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
Thus drive with extra care during the
initial 200 miles (300 km).
Comply with all official speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may from between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake systemApproximately 300 miles (500 km) must
elapse before the brake pads and
rotors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and long service life later
on.
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance), provided that
traffic conditions allow you to do so. To
avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine shut off Ð when
towing, for instance Ð substantially
higher levels of pedal force will be
required to brake the vehicle. optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
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 main-
tenance of the specified tire inflation
pressure.
Incorrect inflation pressures are
a frequent cause of tire problems
and flat tires. Tire pressure also has a
major effect on your BMW's handling
response. Check tire inflation pressures
on a regular basis (refer to page 22), at
least every two weeks and before every
long trip. If you fail to observe these
precautions, incorrect tire pressures
can cause driving instability and tire
damage, ultimately resulting in an
accident.<
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
The tread depth should not drop
below 0.12 in (3 mm), even though, for
example the legally specified minimum
tread depth in Europe is only 0.063 in
(1.6 mm). Below a tread depth of
0.12 in (3 mm) there is an increased risk
of hydroplaning, even at relatively mod-
erate speeds and with only small
amounts of water on the road.
Tread wear indicators, refer to arrow,
are embedded around the tire circum-
ference in the base of the tire tread.
Their locations are indicated on the tire
sidewall with TWI Ð Tread Wear Indi-
cator. At a tread depth of 0.063 in 390de331
(1.6 mm) these indicators, signal that
the tires have reached the legally per-
missible wear limit.
Do not drive on a deflated (flat) tire.
A flat tire greatly impairs steering
and braking response, and can lead to
complete loss of control over the
vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading leads to over-
heating and causes damage inside the
tires. The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be caused
by contact with curbs, etc. This is also
true for irregularities in the vehicle's
handling characteristics, such as a pro-
nounced tendency to pull to the left or
right. Should this occur, respond by
immediately reducing your speed. Pro-
ceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels and tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<

response, use only tires of a single
tread configuration from a single manu-

All passenger car tires must con-

ments in addition to these grades. rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half (1g) times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
TractionThe traction grades, from highest to
lowest, are AA, A, B and C.
Those grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces 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, cornering,

teristics. highest), B and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to a sudden flat tire.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Car Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.

excessive loading, either separately or
in combination, can cause heat buildup

Tire replacement Wheel and tire combinations
Do not use retreaded tires, since
driving safety may be impaired.
This is due to the possible variations in
casing structures and, in some cases,
to their extreme age, which can lead to
a decrease in their durability.<
Tire ageThe date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 3401 indicates that the tire was
manufactured in week 34 of the year
2001.
Although tires may have a theoretical
service life of up to 10 years, BMW
strongly recommends that you replace
all tires after an absolute maximum of
6 years.
The right choice
Never mount wheels and tires that
have not been specifically
approved by BMW for use on your par-
ticular model. Although other wheels
and tires may theoretically have the
same dimensions, variations in factors
such as manufacturing tolerances can
result in contact between tire and body-
work, ultimately leading to serious acci-
dents. If non-approved wheels and tires
are used, BMW cannot evaluate their
suitability, and therefore cannot be held
liable for driving safety.<
BMW has tested certain tires for each
tire size, rated them according to road
safety and approved them. Your BMW
center can inform you which tires have
been tested in this way. Observe pos-
sible national guidelines, e.g. regarding
entry into vehicle documents.
Because various systems on your
vehicle, such as ABS, DSC and
the Flat Tire Monitor, rely on the correct
combination of tires and wheels for
optimal operation, their operation may
be adversely affected if other tires and/
or wheels are mounted .
You should therefore ensure that tires
from a single manufacturer with the
same tread pattern are mounted at all
four wheels. After installing a spare tire
in response to a flat tire you should
always ensure that a tire of the original
specifications is remounted as soon as
possible.<
The use of rims and wheel bolts
that do not meet the specifica-
tions of the original factory-installed
equipment will affect the safe operation
of your vehicle and may cause an acci-
dent and personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias-
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding and can lead to loss of vehicle control. tecting them against light whenever
possible. Protect the tires against con-
tact with oil, grease and fuel.

Special characteristics of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. While "all-season"
tires (M+S designation) provide better
winter traction than summer tires with
the load ratings H, V, W, Y and ZR, they
generally do not achieve the perfor-
mance of winter tires.

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.
Never exceed the maximum speed
approved for your speciÞc winter
tires.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire inflation
pressureWhen the tread wears to a depth of less
than 0.16 in (4 mm) there is a substan-
tial reduction in the tire's ability to pro-
vide adequate traction under winter
driving conditions. To ensure continued
safety, tires with this amount of tread
wear should always 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 wheels/tires.The use of BMW narrow-link snow
chains on winter tires is approved only
in pairs and only on the rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a speed of 30 mph
(50 km/h) while driving with mounted
snow chains.
It is not possible to mount snow
chains with 18-inch wheels and
tires.<
