2003 BMW 330i SEDAN oil

127
Adding engine oilWait until the level has dropped to just
above the lower mark before adding oil.
However, you should never let the oil
drop below the lower mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the 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., out of
reach of children. Comply with all warn-
ing labels and information on lubricant
containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Specified engine oilsThe quality of the engine oil is
extremely important for the operation
and service life of an engine. Based on
extensive testing, BMW has approved
only certain grades of engine oil.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If an approved BMW High Performance
Synthetic Oil should be unavailable, you
may use small volumes of other syn-
thetic oils for topping up between oil
changes. Use only oils with the specifi-
cation API SH or higher.
Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit
this website: www.bmwusa.com to
obtain this information.
Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for driv-
ing in all ambient temperatures.

130Maintenance
The BMW Maintenance SystemThe BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.Service interval displayWhile conventional systems rely on
milage alone to determine when service
is due, the BMW Maintenance System
reflects the actual conditions under
which the vehicle is operated: some
miles are more strenuous than others.
From a maintenance point of view,
62,000 miles/100,000 km accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals accord-
ing to individual operating conditions.
Minimal use drivers – significantly fewer
than 6,200 miles/10,000 km annually –
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use.Service and Warranty Information
Booklet for US models/
Warranty and Service Guide
Booklet for Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.As a precaution against corrosion, if
your vehicle is exposed to potential
damage from unimproved road sur-
faces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
Have your BMW center perform
maintenance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries confirm that your vehicle has
benefitted from regular maintenance,
and are also required for warranty
claims.<

chure.

131 Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust, some of its con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after hand-
ling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument panel. The cover has the let-
ters OBD on it.
This interface makes it possible to
access data on emissions-related com-
ponents using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe
