Wheel and tire
combinationsThe right choice
Use only wheel and tire combinations
that BMW has approved for your
particular vehicle. Variations in factors such
as manufacturing tolerances mean that
even wheels and tires with identical official
size ratings could actually have different
dimensions than the approved units. These
differences could lead to body contact, and
with it the risk of severe accidents . If non-
approved wheels and tires are used, BMW
cannot evaluate their suitability, and there-
fore cannot be held liable for driving
safety.<
BMW tests certain tire brands for each tire
size, classifies them as road-safe and
approves them. Consult your BMW center
for more information. Observe any country-
specific regulations, e.g. on making a
corresponding entry in the vehicle
documents.
The correct combination of wheels
and tires is a vital factor in ensuring
reliable operation of various vehicle
systems such as ABS and DSC.
It is therefore important to ensure that tires
from a single manufacturer with a single
tread configuration are always mounted on
all vehicle wheels. After a flat tire, always
remember to have the specified wheel and
tire combination remounted on the vehicle
as soon as possible.<
Storage Always store wheels and tires in a cool, dry
place with as little exposure to light as
possible. Always protect tires against all
contact with oil, grease and fuels.
Special characteristics of
winter tires Choosing the right tire BMW recommends winter tires Ð M+S
radial tires for use in cold winter driving
conditions. Although all-season M+S tires
provide better winter traction than standard
summer tires with H, V, W and ZR speed
ratings, they generally fail to provide the
same levels of cold-weather performance
as winter tires.
When mounting, always install winter tires
of a single tread configuration and from a
single manufacturer on all four wheels to
ensure safe tracking and secure steering
response. Observe speed ratings
Never exceed the maximum speed for
which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents.
Have this work performed by skilled
professionals only. The technicians at your
BMW center will be glad to assist you with
the required professional knowledge and
specialized equipment.<
Tire condition, tire pressure Because winter tires display a noticeable
loss in their ability to cope with cold-
weather driving conditions once the tread
wears to below 0.16 in (4 mm), to ensure
continued safety you should always have
such tires replaced.
Always maintain the specified inflation
pressures in all tires, and remember to
have the wheel and tire assemblies
balanced every time either a wheel or a tire
is replaced. Snow chains*

are
approved exclusively for use in pairs on

Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
BMW engines are designed to
operate without additives, and their
use could even lead to damage in some
cases. This also applies to the automatic
transmission, the differential and the power
steering system.<
Recommendation: have your oil changed at
your BMW center.
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come
into contact with oil should be thoroughly
washed with soap and water.
Always store oil, grease, etc., well out of
the reach of children; always observe all
warning labels on the containers.<
Please observe all environmental-
protection rules and regulations when
disposing of used oil.< Specified engine oils The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their suit-
ability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High
Performance Synthetic Oil, you can add
small amounts of another synthetic oil
between oil changes. Use only oils with the
API SH specification or higher. Ask your BMW center for details
concerning the specific BMW High
Performance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
Viscosity ratingsViscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.
To avoid the possibility of damage later on,
never use anything other than factory-
approved, nitrite and amino-free extended-
duty antifreeze with corrosion inhibitor.
Your BMW center is familiar with the official
specifications.
Antifreeze and anticorrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Extended-duty antifreeze with corrosion
inhibitor contains ethylene glycol Ð a flam-
mable substance. For this reason, do not
spill antifreeze with corrosion inhibitor on
hot engine parts. It could ignite and cause
serious burns.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used
extended-duty antifreeze with corrosion
inhibitor.<

Maintenance The BMW Maintenance
System The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimal safety. The service
schedule also includes operations related
to the vehicle's comfort and convenience
features, such as replacement of the filters
for the inside air. The ultimate objective is
to furnish economical maintenance by
providing the ideal service for your indi-
vidual vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of great
value. CBS Condition Based Service CBS is a more advanced version of the
Service Interval Display. Sensors combine
with highly-specialized algorithms to
supply service information that reflects
your vehicle's actual operating conditions
more precisely than ever before.
The system now furnishes individual
displays of the times remaining until the
deadlines for specific service operations as
well as official state inspections:
>Engine oil
>Brakes Ð separate for front and rear
>Microfilter/activated-charcoal filter
>Brake fluid >Coolant
>Spark plugs
>Vehicle check
>Official state inspections
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's key, your BMW
service advisor is able to suggest precisely
the right array of service procedures for
your own individual vehicle.
By letting you define a service and mainte-
nance regimen that reflects your own indi-
vidual requirements, Condition Based
Service builds the basis for troublefree
driving.
